Using the pulse oximeter sensor is one of the noninvasive monitoring techniques that can be used to get the estimate of the measurement of one's arterial oxygen saturation. This is an indicator for the percentage of the hemoglobin in his body that is saturated with oxygen while measuring. He should see to it to take an accurate measurement of that substance.

The reading will usually make use of two sources of lights which is also known as light Nellcor sensors. These two lights are called the red and infrared, respectively. They are absorbed by the body's hemoglobin which is then transmitted into the tissues to photodetectors.

There are steps that the person can follow if he wants to get a measurement. For this one, the first thing that must be done is to find the right device that he can use. When it comes to oximeters, there are many types available these days. The two popular choices are the portable handhelds and the fingertip oximeters.

If the device is not the portable type, then he should plug the device into any grounded wall outlets. On the other hand, it will be more convenient for him if the device is portable. If it is the latter, then all he has to do is ensure that it has enough battery for when he is going to use it.

When using it, there is a need for him to wash his hands. He should keep it clean so that he can get an accurate reading. After all, washing his hands will ensure that he reduces the transmission of the body secretions and various other microorganisms.

When done with the washing, the next thing that he will use is the probe along with the Ethicon sutures. This is placed into one's fingers or one's earlobe. Once properly positioned, the device is then turned on. The device will ready the arterial pulse strength to obtain the right measurement.

The measurement will then be displayed on a lighted display screen. Of course, he will know about his oxygen saturation level along with his pulse rate this way. The range considered to be normal is 95 to 100 percent. If it drops below the 85 percentage, then it is recommended that he seeks medical attention.

The reading should then be printed out. The pulse oximeter sensor is usually build with this capability. On the modern models of the said device, the person can even download the readings into his computer.
