There are a great number of different devices that modern medical technology offers. They allow diagnosing different diseases at early stages. One of such important devices is pulse oxymeter. It is used for measuring the amount of oxygen in a patient`s blood. All the measures are performed in a curious way: a device is counting all red blood cells that travel through the light beam. And with this information in a digital form, devices can easily calculate the hemoglobin percentage. To have such measurements done a special clip is placed on the most transparent part of the body, a finger or an ear. That allows performing all the measurements with no need to take blood sample or apply any other "risky" invasive method. That is a significant improvement of technology and all the measurements can be taken at any time, during sleep or even during a certain physical activity. That is a wonderful opportunity to control the hemoglobin level of sportsmen, for example. The clip with which measurements are taken is connected to a control unit which makes all the needed calculations and produces the results. That block can be made pretty simple and small for portable usage as well as in bigger form it can be used in hospitals. Big and more advanced modifications of pulse oxymeters can be connected to a computer and, thus, all the data can be stored on a hard disk to monitor the patient condition through the time. That also makes data of the patient very easy to interpret. It can also be sent to other doctors via e-mail to facilitate complex cases. The principle that the pulse oxymeter employs is quite simple, but as long as complicated devices of laser technology and computer modules are needed, the actual implementation is far from being that simple. All the above said shows that pulse oxymeter can be a pretty complex device, which means that it usually costs a lot of money. And not all the hospitals, especially in developing countries and countries in financial straits can afford a wide use of pulse oxymeters. Then, donating pulse oxymeters can become very helpful. There are many different world wide organizations that have money for donating pulse oxymeters to different hospitals in various countries. There are also many medical equipment manufacturers donating pulse oxymeters they produce. Such humanitarian activity can help many people and possibly save many lives. Novametrix is one of the leading medical devices producers in the world. And according to the report of Rosa DeLauro, Novametrix has been donating pulse oxymeters and other kinds of non-invasive monitors used in critical care to "Children of Chernobyl Relief Fund". Today, more and more medical device producers follow the wonderful example set by Novametrix Company and donate their product to different humanitarian organizations and hospitals. Although it may not be so big for these companies, such aid is very important for every hospital that receive very expensive, but so needed for critical care devices as pulse oxymeters.
