What is the relationship between Pulse Oximeter and Covid19

Oxygen saturation (also called SpO2) is a fraction of the oxygen-saturated haemoglobin, compared to the total haemoglobin in the blood. The normal values of SpO2 range from 92 to 100 percent. For a healthy person, SpO2 values usually fall between 94-96 percent. However, a value below 90 percent during a COVID-19 outbreak could indicate low oxygen level, a condition known as hypoxemia.

Hypoxemia is a symptom that, irrespective of the cause, can lead to multiple issues like organ failure and cardiac arrest if not treated early.
