In this article, we have jotted down the points on how to use the pulse oximeter the right way to help you make an informed decision of whether hospitalization is necessary or not.

How to Use a Pulse Oximeter

To check oxygen saturation, COVID-19 patients isolating at home are requested to use a pulse oximeter to monitor oxygen levels. Here are some pointers to keep in mind when using a pulse oximeter at home:

  • Rest for at least 10-15 mins before checking oxygen level
  • Always put the oximeter on the middle or index finger
  • Don’t move, keep it in the same place to get a correct reading
  • Register the highest result once the reading has stabilised
  • Start recording from the baseline and record at least twice a day unless you notice any changes in your health
  • Consult a doctor immediately in case of breathlessness or dip in oxygen levels to 93 per cent or less

The pulse oximeter displays 2 results: blood oxygen level (SpO2) and pulse rate (PR). Your doctor can tell what numbers are or should be considered normal for you. It is SpO2 which shows the percentage of oxygen concentration in the patient’s blood.
