Background on Pulse Oximeter and Relevance to Covid-19

In brief, a pulse oximeter is…

A pulse oximeter is a medical device that measures saturation of oxygen (called SpO2) in your blood cells). The way it works is it clips to your finger and then the device sends a shining light through your skin, which is analysed to give reading of blood oxygen amount. Some oximeters can be clipped onto ear, nose or toes as well.

Doctors and medical professionals routinely use pulse oximeters in hospitals and clinics for patients suffering from breathing issues or having lungs / heart disorders resulting in breathing problems.  It helps in identifying if adequate oxygen is being carried through your blood or not.

You can use pulse oximeters at home as well for monitoring SpO2 regularly basis for anyone someone recovering at home at advice of doctor.

Covid-19 relevance of Pulse Oximeter

Can low blood oxygen indicate Covid 19?

Many patients with severe cases of Covid-19 are known to experience extremely low levels of oxygen in the blood. This can be measured as SpO2 level by use of a typical finger pulse oximeter. If someone tests positive for novel coronavirus or Covid 19, he or she may experience shortness of breath after few days and consequently results in lower supply of oxygen to blood.

This has increased importance of pulse oximeters in our lives, since this is a fairly simple, effective and quite affordable way of measuring oxygen level in our red blood cells.

However, you should not misunderstand pulse oximetry reading to be a substitute for Coronavirus test. A professor of Pulmonary and Critical Care Medicine at the University of Washington says that Pulse Oximeter reading cannot indicate any Covid 19 infection. This is due to the fact that a Covid 19 infected person experiences lower oxygen levels only after some period (in days) of Covid 19 infection, not immediately after getting infected.


When Do You Need Pulse Oximeter during Covid 19

However, there are situations when it makes perfect sense to use pulse oximetry at home. This is really important for people who have already tested positive for Covid-19 and/or are recovering at home due to lack of isolated bed facilities outside. If you fall into this category or have any body at home in this condition, then you may think of buying and keeping a pulse oximeter at home.

Pulse oximeter can largely help monitor whether a Covid 19 patient may need additional oxygen or other urgent health care support. Some state governments in India are providing pulse oximeter for such patients to encourage increasing home treatment of Covid 19 infections. However, it is best to consult with your doctor once in such situations and not take all decisions yourself.
