Patient's Query

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?


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 %.
