How To Measure Oxygen Saturation With Pulse Oximeter Sensor

By Jessie Uresti


It is a given for some people to make use of the pulse oximeter sensor. This is one of those non-invasive monitoring techniques that is used for estimating the measurement of one's arterial oxygen saturation of the body's hemoglobin. This will indicate the percentage of hemoglobin saturated with oxygen during the time he took the measurement. Be sure to get an accurate reading.

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.

If he wants to know this measurement, he should first start with selecting the right device. The device should properly fit his needs. There are several different models of oximeters available these days. There are even those popular portable handhelds and there are those fingertip oximeters. All he has to do is choose between these two.

To those who have not chosen the portable type, then remember that he has to always plug his device into a wall outlet to make use of it. On the other hand, the portable type is quite convenient since he does not have to plug it into any wall outlet just to make use of it. He just has to make sure that is has enough battery to last him.

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.

The probe should then be placed onto his finger or his earlobe. He might need Ethicon sutures. When done with that, he should then turn the device on. There must be enough arterial pulse strength so that he can obtain the accurate SpO2 measurement.

It is a given that the measurement will be properly displayed on the lighted display screen. He should be able to know the pulse rate along with his oxygen saturation level with this. The normal range is on the 95 to 100 percent. If it is below 85 percent, then it is time for him to seek 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.
