What is the normal oxygen saturation range in a pulse oximeter, and how should a COVID-19 patient use it?

Question

Hello doctor,

My father is diabetic and was diagnosed with COVID-19. The doctor asked me to use a pulse oximeter to check his oxygen levels.

Why does a COVID-19 patient need a pulse oximeter?
What is the normal pulse oximeter range, and how should I use it?

I hope this helps.

Hello,

Welcome to icliniq.com.

I can understand your concern.

A pulse oximeter helps check blood oxygen levels. COVID-19 patients develop hypoxia when the infection is severe and damages the lungs. We need a pulse oximeter to check the patient's hypoxia, or oxygen levels.

The normal range of oxygen saturation is above 94%. I suggest you admit him if his value is below 90%.

I hope this helps answer your query.

Please let me know if I can assist you further.

Thank you.
