Finger Pulse Oximeter Key Buying Considerations

With the rate of technological development taking place in this modern era, even medical instruments and devices are fast becoming smaller and more affordable. When it comes to the finger pulse oximeter, the once massive large equipment can now literally fit in your pocket (with many oximeters weighing less than 2 ounces). What the pulse oximeter does is measure the oxygen saturation level in the blood. These more compact models can provide the same valuable data as compared to the ones which are placed on you when you are in the hospital (and it is just as quick). To use a finger pulse oximeter, you place one end of the device on your fingertip and the reading comes up on the screen in a few seconds.
Here's the basis of how the oximeter works in order to provide accurate readings of the oxygen saturation levels in the blood: infrared light is absorbed by oxygenated hemoglobin and the red light is allowed to pass through. On the other hand, the opposite is said for the deoxygenated blood. Beams of red light and infrared light are directed from the oximeters through your finger and goes onto the photo detector on the opposite end. The photo detector then calculates the ratio of the red light to the infrared light. This then gives the oxygen saturation level. Persons who are healthy will have an oxygen saturation level between 95% to 99%. The oxygen saturation level indicates how well the heart, lungs and blood are supplying organs with oxygen.

3. The main reason for purchasing the oximeter is to measure your oxygen saturation and your pulse rate. Therefore you would only want something that is going to give you accurate and reliable readings.
4. You should also determine if your oximeter is easy to use and if you can read the results clearly through the display. Different devices show the results differently.
For some individuals, having a finger pulse oximeter that they can use at home is quite important. Instead of having to make appointments to go see a doctor or nurse in order to measure their oxygen saturation levels, they can conveniently use a finger pulse oximeter to determine how much oxygen they have in their blood stream.
