Oximeters to Measure Blood Oxygen

oximeter measure blood oxygenThe oximeters are devices that measure oxygen in blood and tissues in a simple and noninvasive, so are ideal for medical use and for educational experiences on physiology in vivo. It is scientifically proven medical devices that measure the oxygen concentration through infrared sensors and calculate the degree of saturation of this gas in blood. As detected electromagnetic radiation absorption by hemoglobin is necessary to remove the paint with acetone on the nail for a correct reading of oxygen saturation values.

By developing the technology of ultrasound, microwave, laser and infrared light has succeeded in developing a wide range of medical devices that act through electromagnetic waves, sonic or physical. Most important is that these devices are available to any user, and you can get a good home oximeter for a small investment of 100 or 200, although some houses have as Quirumed cheaper models by just over 60 euros plus shipping shipment. In hospitals are classified as having a fixed oximeter plethysmographic curve but for private use or educational enough portable pulse oximeter, hand or finger. Nonin is one of the brands that specialize in pulse, you indicate both the oxygen values as the number of heartbeats per minute.

The normal values of oxygen in blood vary between 95% and 97% SaO2 so easily detected irregularities to be decreases below 95% saturation of O2. Go2 Nonin finger pulse oximeter is cheaper brand, you can buy for $ 99 in a few days pmedicalonline.net and start making the first tests with your own finger. It is designed to be used with fingers of size from millimeters to a centimeter and has 2 year warranty. Among the additions, plus a charger Go2 also have some support for adequate transportation, avoid losses and protect against falls, such as a bag, a briefcase and a simple string. There are several other notebook models Nonin 9500 Onyx from $ 200, and handheld pulse oximeters from $ 400 to $ 600 as the Nonin 2500 PalmSAT.

The main functions of this is patient care and monitoring the level of oxygen in cases of asthma there may be respiratory distress, cyanosis, control of oxygen therapy and the assessment of exercise tolerance. So that according to these functions can perform tests to see how exercise or changes in breathing may alter the level of oxygen in blood. You can also perform other experiences related to research projects specific to the Baccalaureate, to correlate the age with the amount of oxygen in the blood, or measure differences in this value between men and women.

In clinical practice are complementary to the gases, and are widely used in pediatrics to be the least invasive and most friendly to children. So a little ingenuity can be placed permanently if necessary, and notify you of any decrease in blood oxygen saturation. The main disadvantage of these devices is that regard, a gas analysis provides less information: do not measure the concentration of carbon dioxide, or the blood pH, and also for oxygen values are accurate only above 80-90%, so that are not useful for certain pathologies. As advantages we should mention its use simple and fast, in addition to its noninvasive application already discussed earlier.
