Fetal Monitors

Alien asked:


A pregnancy ultrasound is a safe and effective way of looking inside the womb of a pregnant woman. An ultrasound will use sound waves to transfer pictures of a fetus to a monitor at the bedside. A transducer is used on the abdomen and a full bladder is usually required to raise the uterus up closer to the surface of the abdomen for a better view. This is a non-invasive way to check on the condition of the fetus and in a lot of cases, to find out if you are having a boy or girl!

There are several reasons why your doctor may order an ultrasound for you. One reason is to detect and confirm pregnancy in the early stages. By measuring the fetus, the doctor will have a more accurate idea of your due date and he will also be able to determine that the fetus is in the cavity of the uterus.

Another reason for a pregnancy ultrasound may be due to vaginal bleeding in early pregnancy. If you experience cramping and bleeding early in pregnancy, your doctor may order an ultrasound to check for a visible heartbeat. This can be detected as early as six weeks into the pregnancy. If no heartbeat is detected and the gestational sac is malformed, it probably indicates a miscarriage.

When the doctor uses an ultrasound to determine gestational age, he uses several different measurements. The first measurement he will look at will be the crown to rump length. This gives a very accurate estimation of the gestational age.

The next measurement will be the diameter between both sides of the head. This measurement is taken at around 13 weeks.

The doctor will then look at the femur length of the fetus. This is the longest bone in the body and helps to give an accurate estimate of gestational age and growth.

Another important aspect of using a pregnancy ultrasound is to diagnose fetal abnormalities. The ultrasound can pick up abnormalities such as, spina bifida, hydrocephalus, dwarfism and other congenital defects. This will prepare the doctor and the parents in the event an abnormality is found. Sometimes, depending on the condition, special equipment will be needed in the delivery room. Knowing what to expect ahead of time helps everyone to be prepared.

A new and exciting development in the ultrasound is the 3-D and 4-D ultrasound. This type of ultrasound can transfer images to the monitor and they can be processed into 3-D images. You are able to see your baby’s features and movements. These ultrasounds are also able to pick up smaller defects, such as cleft palates.

If this is your first pregnancy, do not be alarmed when your doctor orders an ultrasound for you. This is normal practice and it will give you the unforgettable experience of seeing your baby for the very first time. Bring your partner along and cherish the moment when you first lay eyes on your baby through your pregnancy ultrasound.

Ruben Knisely asked:


In vitro fertilization is the procedure that takes sperm and eggs to fertilize them in a laboratory and plant the embryo thus created in the ovary. In IVF sperm and eggs may be used both from the partners and from donors.

Assisted reproductive procedures using your own eggs require some hormonal treatment to control your ovulation and avoid unpredictable ovulation. Usually this procedure is done by using on of two similar types of gonadotropins- releasing hormone analogue. We present you two examples of controlled ovulations:

* - GnRH agonist injected or on nasal administration for 10 days to shut down the ovaries. Next, you undergo daily ovary-stimulating hormone injections and close monitoring for 2 weeks before egg retrieval. At home, you or your partner injects you with gonadotropins or follicle-stimulating hormone (FSH) to make your ovaries produce multiple eggs (super ovulation).

* - FSH treatment with injections , then adding GnRH antagonist injection after about 5 days; this stops the production of luteinizing hormone (LH) within an hour or two.

Blood estrogens level is checked after a week, and ultrasound monitoring to see whether the eggs in the follicles are maturing. Dosage changes in the second week based on the results and monitoring continues. If follicles fully develop, you are given a human chorionic gonadotropins (hCG) injection to stimulate the follicles to mature. The mature eggs are collected 34 to 36 hours later by needle aspiration guided by ultrasound.

Collecting the sperm. There are two ways of doing that: through masturbation or through a small incision in the scrotum. The second method is used when there is a problem with the sperm production or when ejaculation is blocked.

The fertilization and the embryo transfer. The sperm and eggs are placed in a dish in a sterile environment with controlled temperature and pressure for 48-120 hours. The fertilized eggs are then selected and the best 2-4 embryos are inserted into the uterus through a catheter (a thin flexible tube). The remaining embryos are cryopreserved for future attempts.

The embryos thus implanted in the uterus may then result in pregnancy and birth of one or more children.

What comes after treatment?

IVF technique can be very demanding for a woman. It requires periodic blood tests, hormones tests, periodic doctor consultations, plus, some of the injections the treatment requires may be quite painful, thus it can trigger emotional issues.

The good side is that this procedure is done on an outpatient basis and need a short recovery time. Yet, depending on the doctor’s recommendation, the patient may need on bed rest for a few days or meet some restrains and encounter cramps.

Reasons and results of IVF

This treatment is an option if one of the following is causing infertility:

* - Woman suffers from severe endometriosis

* - Man encounters low sperm count

* - Failure of artificial or intrauterine insemination

* - Unexplained infertility for a long time

* - Blocked or missing fallopian tubes in a woman

* - Unsuccessful tubal ligation reverses surgery

IVF success rate is about 25 percent. It is very closely connected to many factors that caused infertility, prior pregnancies, genetic inheritance and age.

Once the woman ages, so does her supply of eggs and the chances for healthy pregnancy and birth even in case of IVF. So, many women that passed the age of 40 choose donor eggs instead of their own for a higher rate of success.

What are the risks

OHS and multiple pregnancy are the first risks of IVF.

Super ovulation needs close monitoring on the ovaries, blood and hormones level during the IVF procedure because it has a 0.5 - 2 % rate of developing severe OHS which is rarely life threatening.

Multiple pregnancies represent a risk for both mother and children. 30% of the IVF pregnancies produce twins, 5%produce triplets and 0.6% produce more then 3 children.

Before deciding how many embryos to implant in your uterus, the doctor will advice for the best options pending on all the factors involved. You will most likely have this conversation with your doctor before the treatment begins and again before the implantation. In case if more than 2 embryos will be implanted, you will probably be advised on the multi fetal reduction pregnancy to increase the chances for a healthy pregnancy and healthy child.

Tom Parker asked:


When you are pregnant it is increasingly important to watch what you eat. Since you are now eating for two every bad nutritional choice will not just effect you, but also your baby. In general terms, there are two things that you need to be monitoring. First, you need to monitor how much you are eating as getting the correct caloric intake during pregnancy is crucial. Secondly, you need to be watching what you eat because the wrong types of food can be damaging to your baby. In this article I will discuss both the above issues in greater detail and provide you with some solid nutritional advice for your nine month pregnancy.

As already stated getting your caloric intake right is very important during pregnancy. Consuming too many calories and putting on too much weight whilst pregnant can increase your risk of contracting a blood pressure related disease. Contrastingly, not getting enough calories during your pregnancy can lead to your baby being born underweight and even slow down fetal development.

So where do you go for advice for on the number of calories you should be consuming each day? Your doctor should always be your number one port of call. They are professionally trained in this area and also know about you and any specific issues affecting you and your baby. Every pregnant woman is unique and will have slightly different requirements. Therefore, your doctor is the best source of information in this area and should not be overlooked in favour of this article.

However, you can determine the general amount of calories you need using a free online BMR & Caloric Intake Calculator (just do an Internet search). This calculator will determine your recommended daily caloric intake BEFORE pregnancy. You then need to add approximately 300 daily calories to this figure during your second and third trimester to support your baby’s increased rate of growth. Generally, no additional calories are needed during the first trimester but again this may not be the case for you. Only your doctor will know for sure.

Once you have your daily caloric intake sorted you also need to consider what you are eating. There are a number of foods that you need to cut down on or even avoid completely whilst you are pregnant. I have outlined three of these foods in the list below:

1) Alcohol:- Whilst there are no set recommendations on the amount of alcohol you can consume during pregnancy, a number of sources suggest that the number of alcohol related birth defects is on the rise. Alcohol can also potentially lead to miscarriage, low birthweight or stillbirth. These are quite significant risks which can be avoided by giving up alcohol during your pregnancy. I’m not saying it’s going to be easy but if you want to be a responsible mother you should have the discipline to avoid alcohol for nine months.

2) Uncooked Meat & Dairy Products:- Deli meats, undercooked eggs, unpasteurised cheeses etc often contain pathogens (such as e.coli, salmonella and listeria). These pathogens can lead to serious infection for both you and your baby. In pregnant women the symptoms can include diarrhea, vomitting and dehydration. In the baby these pathogens can ultimately lead to stillbirth and miscarriage. Therefore, if you are a fan of these types of food try to limit your intake during pregnancy or avoid them completely if you can.

3) Unwashed Fruits & Vegetables:- By consuming unwashed fruit or vegetables you are putting yourself at serious risk of Toxoplasma infection. Whilst Toxoplasma is generally not a risk for pregnant women it can be seriously damaging for undeveloped babies. It only takes a few seconds to wash the fruits and vegetables you consume so make sure you always clean your fruit and veg before consumption. This small act can make a huge difference to the health of your unborn child.

This article is not intended to scare you or make you worry. My aim is to make you aware that things you didn’t previously regard as important could now be very important. An undeveloped child is much more fragile than a fully developed human being and as an expectant mother you are ultimately responsible for the health of your baby. If you want the best for your baby, read this article, take the advice on board and then go consult your doctor regarding your diet as an expectant mother.

AMANDA ISBITT asked:


How does the Doppler work ?

The Doppler listens to the reflections of small, high frequency sound waves that are reflected from within the womb. These sound waves are picked up by the probe and amplified through the hand held speaker so that you can hear them clearly. There are a variety of sounds that can be heard, including the fetal heart beat/tone, each of which is distinctive and so are easily identified. You can hear kicks and hiccups when your baby grows larger. Sounds can generally be heard from 10-12 weeks of your pregnancy.

Is the Doppler safe ?

All the Fetal Doppler’s available through reputable internet stores are the same, or use the same technology as the Doppler’s used by your midwife or doctor during your examinations throughout your pregnancy. Ultrasound technology has been used for many years without any adverse effect on either the foetus or mother.

Fetal Doppler’s have an incredible safety record. They have been used daily for the last thirty years around the world. It is estimated around five million are in use every single day. No adverse effects to either mother or baby have ever been reported.

Please do not confuse Doppler’s with ultrasound scanners used in a hospital to show images of your baby. Our Doppler’s use ultrasound in an extremely low power output. This is why they are run on a household battery alone.

What if I can’t find the heartbeat ?

Finding the heartbeat can be daunting at first as your baby may be lower than you expect. Make sure you have used a generous amount of coupling gel and position the probe low down on your abdomen. If you do not hear any sound at first, move the probe slowly until you pick up the heartbeat. The fetal heart beat sounds like a galloping horse and is very fast at 120-160 beats per minute. If you still have difficulty then refer to the leaflet enclosed with your Doppler.

How can I tell it’s not my heartbeat I can hear?

The sound of the fetal heartbeat is distinctive, but can often be confused with other sounds at first. You may well have heard it already during your antenatal appointments with your midwife or doctor. It is a regular fast beating sound, not to be confused with the swishing sound of the placenta.

- A roaring sound, like waves on a beach, is the sound of your placenta.

- A ‘whooshing’ noise is the sound of the blood supply to the placenta.

- Your own pulse! Don’t forget that your baby’s heartbeat is about twice as fast as this.

- A pulse that is more high-pitched than your baby’s heartbeat, but at the same speed. This is the pulse through the umbilical cord; a very pregnant and reassuring noise !

How many heartbeats per minute will I hear ?

The fetal heartbeat is much faster than your own and is usually between 120 and 160 beats per minute. However, the heartbeat is not likely to remain constant and will vary depending on the time of day and amount of activity. The readings from the Doppler should not be used for self-diagnosis as any interpretation is complicated and requires detailed medical training.

Do I need a special lotion or ultrasound gel ?

The probe on your fetal doppler needs a dense liquid to pick up the sound waves from the womb. The coupling gel that is provided with your Doppler is to be used to ensure the high quality and clarity of the sounds you can hear.

Doppler Tips

- A very easy way to find the heartbeat is to take your Doppler with you to your next prenatal appointment. Your OB or midwife can help you locate your baby’s heartbeat and provide you with helpful doppler tips.

- A full bladder may help, especially in early pregnancy.

- Early in pregnancy, start your fetal doppler in line with the belly button right above the pubic hair. As pregnancy progresses, your fetal doppler will find the heartbeat higher up the abdomen.

- Move the doppler probe VERY slowly - it is quite easy to go over the heartbeat. Also, if you move the probe too fast it may cause interference noise.

- Tilt the doppler probe downward toward the pubic bone.

- Be sure to use plenty of Doppler gel. If you run out of gel, you can buy additional doppler gel from us.

- The baby is normally positioned far deeper in the pelvis than you would imagine.

- Do not panic if you do not pick up the heartbeat immediately, some days you will it and other days the baby may be in hiding.

Josh Stone asked:


Projection radiography

you may call them radiographs or more formally Roentgenographs, because they’re named after the discoverer of X-rays, Wilhelm Conrad Roentgen. These are often used for evaluation of bony structures and soft tissues. An X-Ray machine directs electromagnetic radiation upon a region in the body. The lower the density of the object, the more light passes through. Thus radiation tends to pass through skin, fat, muscle, and other tissues, but is absorbed by bones, tumors, and lungs affected by severe pneumonia. Radiation which has passed through a patient then exposes onto an X-ray film. Areas of film exposed to higher amounts of radiation will usually appear dark gray after development. The unexposed areas of film of course stay white.

Fluoroscopy

Fluoroscopy and angiography are special applications of X-ray imaging, in which a fluorescent screen or image intensifier tube is connected to a small television system, which allows real-time imaging of structures in motion. Radiocontrast agents are administered, which are often swallowed or injected into the body of the patient, that help delineate anatomy such as the blood vessels, the genitourinary system or the gastrointestinal tract. There is a radiocontrast agent for each specific type of evaluation. For example, barium in a suspension is administered into the gastrointestinal tract and the image is taken with fluoroscopy or radiography. Radiocontrast agents, which ’soak up’ X-ray radiation, in conjunction with the real-time imaging allows demonstration of dynamic processes. Peristalsis in the digestive tract or blood flow in arteries and veins can easily be seen dynamically this way, for instance.

CT scanning

CT imaging uses X-rays in conjunction with computing algorithms to take an image of a variety of soft tissues in the body. CT is acquired in the axial plane, while coronal and sagittal images can be rendered by computer software reconstruction. It is of course only recently that the combined studies of computer imaging such as 3D ray-tracing and Computer Assisted Design have made this process possible. Yes, CT imaging owes a little debt to movies like “Tron”! Radiocontrast agents are often used with CT for enhanced delineation of the patient’s anatomy. Intravenous contrast allows 3D reconstructions of arteries and veins, showing them as a network of branching tunnels in real-time space. While radiographs provide higher resolution for bone X-rays, CT can generate much more detailed images of the soft tissues. CT exposes the patient to more ionizing radiation than a radiograph, which is the main reason it isn’t used any more oftan than it needs to be.

Ultrasound

Medical ultrasonography uses ultrasound, literal high-frequency sound waves, to visualize soft tissue structures in the body in real time. No ionizing radiation is involved, but the quality of the images obtained using ultrasound is highly dependent on the skill of the person performing the exam, who is known as the ultrasonographer. The use of ultrasound in medical imaging has developed mostly within the last thirty years. The first ultrasound images were static and two dimensional, but with modern-day ultrasonography 3D reconstructions can be observed in real-time. Because ultrasound does not utilize ionizing radiation like radiography, CT scans, and nuclear medicine imaging techniques, it is generally considered safer. For this reason, this imaging method plays a vital role in obstetrical imaging. Fetal development can be thoroughly evaluated, allowing early diagnosis of fetal anomalies or confirmation of a normal gestation.

MRI/NMR

MRI uses strong magnetic fields to align spinning hydrogen proton nuclei within body tissues, then uses a radio signal to disturb the axis of rotation of these nuclei. It then observes the radio frequency signal generated as the nuclei return to their baseline states. MRI scans give the highest quality soft tissue contrast of all the imaging modalities. With advances in scanning speed and spatial resolution and improvements in computer 3D algorithms and hardware, MRI has made greatleaps forward in the recent years. One distinct disadvantage is that the patient has to hold still for long periods of time in a noisy, cramped space while the imaging is performed. Recent improvements in magnet design like wider, shorter magnet bores and more open magnet designs, have brought some relief for claustrophobic patients, who previously had to be sedated – unfortunate if you are looking at the brain on the MRI, since the brain shows different activity when sedated. MRI has it’s best benefit in imaging the brain, spine, and musculoskeletal system. The modality can be contraindicated for patients with pacemakers (watch out for those magnets!), certain types of cerebral aneurysmal clips or metallic hardware due to the strong magnetic fields. Areas of present advancement include functional imaging, cardiovascular MRI, as well as MR image guided therapy.

Nuclear medicine

Nuclear medicine imaging, our newest technology, involves the administration into the patient of substances labeled with radioactive tracers which have affinity for particular tissues. The heart, lungs, thyroid, liver, gallbladder, and bones are commonly evaluated for particular conditions using nuclear medicine techniques. While anatomical detail is limited in these kinds of images, nuclear medicine is useful in displaying physiological functions. For instance, processes such as the growth of a tumor can often be monitored, even when the tumor cannot be adequately visualized using any of the other methods. The principal imaging device is the gamma camera which detects the radiation emitted by the tracer in the body and displays it as an image on a computer monitor. Often the information is converted into a series of slices through the body like a loaf of bread. In the most modern devices, nuclear medicine images can be fused with a CT scan taken at the same time so that the physiological information can be super-imposed with the anatomical structures to improve diagnostic accuracy. PET scanning is another kind of nuclear medicine. The applications of nuclear medicine can include the scanning of bones, which traditionally has had a strong role in the staging of cancers. Molecular Imaging is the new and exciting frontier in this field.

They say that a picture is worth a thousand words, but the development of each of these technologies to show doctors what’s happening inside the body in a non-invasive fashion has been worthwhile for saving many times a thousand lives!

Smruti Ranjan Sarangi asked:


Monitor is another term for display screen. The term monitor, however, usually refers to the entire box, whereas display screen can mean just the screen. In addition, the term monitor often implies graphics capabilities.

There are many ways to classify monitors. The most basic is in terms of color capabilities, which separates monitors into three classes:

1- Monochrome: Monochrome monitors actually display two colors, one for the background and one for the foreground. The colors can be black and white, green and black, or amber and black.

2- Gray-scale : A gray-scale monitor is a special type of monochrome monitor capable of displaying different shades of gray.

3- Color: Color monitors can display anywhere from 16 to over 1 million different colors. Color monitors are sometimes called RGB monitors because they accept three separate signals—red, green, and blue.

After this classification, the most important aspect of a monitor is its screen size. Like televisions, screen sizes are measured in diagonal inches, the distance from one corner to the opposite corner diagonally. A typical size for small VGA monitors is 14 inches. Monitors that are 16 or more inches diagonally are often called full-page monitors. In addition to their size, monitors can be either portrait (height greater than width) or landscape (width greater than height). Larger landscape monitors can display two full pages, side by side. The screen size is sometimes misleading because there is always an area around the edge of the screen that can’t be used. Therefore, monitor manufacturers must now also state the viewable area—that is, the area of screen that is actually used.

The resolution of a monitor indicates how densely packed the pixels are. In general, the more pixels (often expressed in dots per inch), the sharper the image. Most modern monitors can display 1024 by 768 pixels, the SVGA standard. Some high-end models can display 1280 by 1024, or even 1600 by 1200.

Another common way of classifying monitors is in terms of the type of signal they accept: analog or digital. Nearly all modern monitors accept analog signals, which is required by the VGA, SVGA, 8514/A, and other high-resolution color standards.

A few monitors are fixed frequency, which means that they accept input at only one frequency. Most monitors, however, are multiscanning, which means that they automatically adjust themselves to the frequency of the signals being sent to it. This means that they can display images at different resolutions, depending on the data being sent to them by the video adapters.

Other factors that determine a monitor’s quality include the following:

1- Bandwidth: The range of signal frequencies the monitor can handle. This determines how much data it can process and therefore how fast it can refresh at higher resolutions.

2- Refresh rate: How many times per second the screen is refreshed (redrawn). To avoid flickering, the refresh rate should be at least 72 Hz.

3- Interlaced or noninterlaced: Interlacing is a technique that enables a monitor to have more resolution, but it reduces the monitor’s reaction speed.

4- Dot pitch : The amount of space between each pixel. The smaller the dot pitch, the sharper the image.

5- Convergence: The clarity and sharpness of each pixel.

TOUCH SCREEN MONITOR

A touchscreen is an easy to use input device that allows users to control PC software, DVD video, camera etc. by touching the display screen. We manufacture and distribute a variety of touch screen related products. A touchscreen is an input device that allows users to operate a PC, camera etc. instruments by simply touching the display screen. Touch input is suitable for a wide variety of computing applications. A touchscreen can be used with most systems as easily as other input devices such as track balls or touch pads.

How Does a Touchscreen Work? A typical touchscreen input system is basically an input device like a mouse , trackpad or ball pens etc.. A touchscreen system is made up of a touch sensor, a controller card, and a software driver.

What Are Touchscreens Used For? Touchscreen systems are being used in a variety of applications, including point-of-sale systems, public information displays, industrial control systems, and more.

Touchscreen monitors have become more and more commonplace as their price has steadily dropped over the past decade. There are three basic systems that are used to recognize a person’s touch: 1- Resistive 2- Capacitive 3- Surface acoustic wave

The resistive system consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. These two layers are held apart by spacers, and a scratch-resistant layer is placed on top of the whole setup. An electrical current runs through the two layers while the monitor is operational. When a user touches the screen, the two layers make contact in that exact spot. The change in the electrical field is noted and the coordinates of the point of contact are calculated by the system. Once the coordinates are known, a special driver translates the touch into something that the operating system can understand, much as a computer mouse driver translates a mouse’s movements into a click or a drag.

In the capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touchscreen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.

On the monitor of a surface acoustic wave system, two transducers (one receiving and one sending) are placed along the x and y axes of the monitor’s glass plate. Also placed on the glass are reflectors—they reflect an electrical signal sent from one transducer to the other. The receiving transducer is able to tell if the wave has been disturbed by a touch event at any instant, and can locate it accordingly. The wave setup has no metallic layers on the screen, allowing for 100-percent light throughput and perfect image clarity. This makes the surface acoustic wave system best for displaying detailed graphics (both other systems have significant degradation in clarity).

Another area in which the systems differ is in which stimuli will register as a touch event. A resistive system registers a touch as long as the two layers make contact, which means that it doesn’t matter if you touch it with your finger or a rubber ball. A capacitive system, on the other hand, must have a conductive input, usually your finger, in order to register a touch. The surface acoustic wave system works much like the resistive system, allowing a touch with almost any object—except hard and small objects like a pen tip.

As far as price, the resistive system is the cheapest; its clarity is the lowest of the three, and its layers can be damaged by sharp objects. The surface acoustic wave setup is usually the most expensive.

MONITORING TOOLS

There are many types of tools, devices, instruments and software available in market for monitor. Some of the tools names I am giving below:

Blue eye 2 monitor calibration tool For accurate professional color rendering, the LaCie blue eye 2 with hardware-assisted LCD and CRT monitor calibration is an easy, compatible color evaluation tool.

Monitor with Built-In DVR and 4 Cameras Observe and record all your security activities with this all-in-one system. Includes monitor with built-in digital video recorder and 4 color.

And many other tools available in market.

FLAT SCREEN MONITOR

You don’t have to feel boxed in by today’s selection of computer monitors. Nor must you purchase a space-swallowing monstrosity to view text and graphics. Modern-day monitors are an amalgam of fashion and functionality.

There are two main types of monitors: CRT flat-screen monitors and LCD flat-panel monitors.

Less expensive, cathode-ray tubes (CRTs) are the most common type of monitor. While earlier models have slightly rounded screens, today’s flat-screen CRTs are quickly gaining in popularity.

Whereas the origins of CRT technology can be traced to television sets, liquid crystal displays (LCDs) have long been used in laptop computers. LCDs often deliver sharper and brighter images than their bulkier counterparts. And although they are traditionally more expensive than CRTs, LCDs are significantly dropping in price as they enter the mainstream market.

So is it better to stick to tried-and-true CRTs or jump on the LCD wave? Consider the following:

Save space on your desk

In today’s world of home offices and cramped quarters, size matters. Choose a resolution to suit your needs. LCDs might save on space but CRTs offer better sightlines. In addition to supporting multiple resolutions, CRTs let users view images clearly from various angles. LCD monitors, on the other hand, often appear blurry or dim when viewed from the side.

There are graphics people who still prefer a very large CRT flat-screen display to an LCD monitor. Digital photography enthusiasts will appreciate LCDs’ sharp and bright images, especially when enhancing and touching up digital photos. LCD monitors also prevent consumers from straining their eyes when staring at the screen, says Park.

Research upkeep and longevity

Whether your preference is a sturdy CRT or a lightweight LCD, both types of monitors enjoy an average lifespan of five to seven years.

Whereas CRT screens can be cleaned with a cloth, oil from a person’s skin can leave tough-to-remove markings on an LCD screen. When purchasing an LCD monitor, be sure to ask a store clerk to point you in the direction of appropriate cleansing solutions and wipe-ups in order to extend the life of your monitor.

FLAT PANEL MONITOR

A flat panel monitor can refer to either a computer or television monitor that does not use cathode ray tube (CRT) technology, but commonly LCD or plasma technology. This allows the monitor to have a thin profile, which is how the flat panel monitor gets its name. Because of its light weight, small footprint, clarity and digital technology, the flat panel monitor has become the monitor of choice.

Prior to the flat panel monitor, the CRT monitor was standard. These monitors are easily recognizable by the bulging back or picture tube. Vacuum tube monitors are not only bulky and heavy, but they are environmentally unfriendly and emit more radiation than a flat panel monitor.

While there are many advantages to a flat panel monitor, there are also one or two potential disadvantages. A limited viewing angle can be one, although this is easily avoided by shopping discriminately, as the viewing range is included in the specifications of these products. A second potential disadvantage is being bound to the “native resolution.”

A CRT monitor will display sharp text in any supported resolution, but a flat panel monitor only delivers perfectly clear text in the native resolution. On a 19-inch screen this might be 1280×1024 pixels. Switching to a lower resolution will make text appear slightly blurred or fuzzy.

Why would anyone want to switch to a lower resolution? In higher resolutions, images improve but they also become smaller. For instance, the icons on a desktop, toolbars within software, and menus within the operating system are all reduced at higher resolutions. Though many of these items can be adjusted up, some people prefer a lower resolution to get overall larger images on screen. This might be a particular concern for those with visual disabilities. In this case, one should carefully view the flat panel monitor prior to purchase to be sure the native resolution will be comfortable.

Flat panel monitors have decreased steadily in price while improving in quality. Gamers and video-editing professionals tended to avoid these monitors initially because of “ghosting” with fast moving graphics, but this is no longer an issue. A faster response time and increased viewing angle have made the flat panel monitor more popular than ever. With its clear digital picture, space-saving footprint, and ultra-light weight, the flat panel monitor is a welcome improvement over its CRT predecessor.

Juliet Cohen asked:


Eclampsia is the occurence of seizures in a pregnant woman. Usually eclampsia occurs after the onslaught of pre-eclampsia though sometimes no pre-eclamptic symptoms are recognisable. The reason of eclampsia is not easily understood. Researchers believe a person’s genes, diet, blood vessels, and neurological factors may play a role. However, no theories have yet been proven. Eclampsia follows preeclampsia, a serious complication of pregnancy marked by high blood pressure, weight gain, and protein in the urine. Women with very high blood pressure, headaches, vision changes, or abnormal blood tests have severe preeclampsia and are at high risk for seizures. The disease process can begin mild and stay mild, or can be initially diagnosed as eclampsia without prior warning. Eclampsia is more common in young women and those older than age 35.

The trademark of eclampsia is seizures. Similar to preeclampsia, new changes and symptoms may be existing and change according to the organ structure or systems that are affected. These changes can affect the mother only, baby only, or more commonly affect both mother and baby. The majority of cases are heralded by pregnancy-induced hypertension and proteinuria but the only true sign of eclampsia is an eclamptic convulsion, of which there are four stages. Symtoms of preeclampsia include swelling of hands and face, gaining more than 2 pounds per week, headache, vision problems, and stomach pain. Patients with edema and oliguria may develop renal failure or pulmonary edema. There is no known prevention. However, it is important for all pregnant women to get early and ongoing medical care. This allows for the early diagnosis and treatment of conditions such as preeclampsia.

A woman with eclampsia should be continously monitored. Delivery is the handling of selection for eclampsia in a pregnancy over 28 weeks. Prevention of paroxysm is normally done using magnesium sulfate with a loading of magnesium sulfate 20% resolution, 4 g IV over 5 minutes. Women may be given medicine to prevent seizures. Magnesium sulfate is a safe drug for both the mother and the baby. Delivery should take place as soon as the woman’s condition has stabilized. Delaying delivery to increase fetal maturity is unsafe for both the woman and the fetus, after delivery the womans health relative to the condition is improved drastically. Delivery should occur regardless of the gestational age. Medication may be used to lower the high blood pressure. The condition is then relieved with the delivery of the baby. Delivery may be induced if blood pressure stays high despite medication.

Do you like it? I cant seem to hear anything with it. I can hear my own heartbeat, but not the babies. Any thuds I hear are from moving the monitor. I can hear an ocassional kick. Besides that it seems to be a waste of money.
