subject: The Benefits Of Using A Pulse Oximeter [print this page] Oxygen saturation is a measurement of the number of oxygen molecules found in a persons blood. The blood molecule, hemoglobin, can only carry a maximum of four oxygen molecules. To get this measurement in the human body, doctors get a blood sample from the patient. However, the more common and accessible way is to use a pulse oximeter.
In todays medical world, the pulse oximeter has provided a lot of advantages in measuring the oxygen-blood levels as oppose to the old of taking a blood sample and analyzing it form there. This method is still used for verification or when there is more time is available. However, if you are looking for easiest and fastest way the oxygen saturation of a person, the oximeter is the best device to use.
As compared to other methods, the oximeter can determine the saturation of oxygen within seconds, not minutes. The use of arterial blood gases take a longer time because they have to go through the blood gas lab to be measured and analyzed. In case of emergencies, the sudden need to measure the oxygen level in the blood should be made faster.
Another advantage is that this device can easily be used by anyone. Medical training is not needed when using an oximeter. Since there are already many portable versions, an ordinary person can use it and measure his own oxygen level. Its as easy as simply pressing a button and waiting a few seconds. New models today are more accessible and easy to use as oppose to older versions that are larger in size.
There is some debate on whether or not the use of a pulse oximeter is accurate or not. In most cases, it will measure what is needed at optimum speed. However, it should not be the only basis when measuring the oxygen saturation. If time permits, the blood should still be taken through traditional procedures for further study. In other scenarios like people who have chronic conditions, the levels can vary and thus need further analysis. A patient may show that he has low oxygen levels but this may be only due to his chronic condition and could change through time.
Using a pulse oximeter truly has a lot of advantages. Its easy to use, portable, and measures what you need faster. In other versions, you can even measure burned calories and heart rate. However, if you have a serious medical condition, the use of this device may be limited and an extensive analysis of your oxygen saturation is needed.
