How to use an Oximeter- Simple Steps to operate a Oximeter


In these desperate times, where we are helpless with medical treatments for Covid-19 patients, it would be better to learn to use the pulse oximeter at home. These units are known to track the health of patients through the measurement of the oxygen level of the blood. It estimates the oxygen saturation of the blood and the pulse rate by using the light beams which provide information about the amount of oxygen carried in the blood. The Oximeters are preferred as they track the oxygen levels painlessly and without drawing the blood sample.

As the Oximeter is used so commonly these days, we should know how to use the oximeter at home to track the health of patients. So there is a guide following simple steps for the use of an Oximeter at home.

How to use a Pulse Oximeter at home

Step 1– Remove any nail polish/false nails and warm your hand if cold.

Step 2– Rest for at least 5 minutes before taking your measurement.

Step 3– Rest your hand on your chest at heart level and hold it still.

Step 4– Switch on the Oximeter and place it on your middle or index finger.

Step 5– The reading takes time to steady so keep the oximeter in place for at least a minute or longer if the reading is not stable.

Step 6– Record the highest result once it has not changed for 5 seconds.

Step 7– Identify each reading carefully.

Step 8– Start recording from baseline and record three times a day at the same time. Take extra measures if you feel a change in your health.

In case of emergency, please contact the Doctor for consultation.
