pulse oximeter

A pulse oximeter is essentially a small clip-like device and it can be attached to a body part like a finger, earlobe or toes.

With the COVID-19 pandemic in full swing, it is advisable for people to always keep a tab on their blood oxygen levels. Hence, it is advisable to always use a pulse oximeter as it non-invasive and painless. It also calculates the amount of oxygen in the blood in places which are farthest from the heart.

A pulse oximeter is essentially a small clip-like device and it can be attached to a body part like a finger, earlobe or toes. One can get a good oximeter between Rs 1,000 and Rs 2,000. An oximeter can also be used for other health issues which include Asthma, Lung Cancer, Pneumonia, chronic obstructive pulmonary disease and more.

How does a pulse oximeter work?

When the pulse oximeter is attached to your finger, earlobe or toe beams multiple small lights pass through to your body part the oximeter is attached too. In the process, the amount of oxygen in your blood can be measured.

This is how to use a pulse oximeter
  • The clip style pulse oximeter can be placed on the finger, earlobe, or toe. It will not prick you  – all you feel is a small amount of pressure.
  • The finger or the body part should be placed directly under the light.
  • It needs to be mentioned here that you might have to remove any fingernail polish and this is dependent on what kind of pulse oximeter you purchase.
  • Now, turn on the probe.
  • So, as soon as the probe is turned on, within seconds the probe will start relaying accurate information and this gives information about your blood oxygen saturation levels.
  • So, now the test is over and you have your results, all you need to do is take off the probe and the device will shut down automatically.

Check the level and any count which is under 95 is quite problematic and this is when, you have to consult a medical practitioner.
