Our blood oxygen level is a measure of how much oxygen our RBC are carrying. Pulse oximeter and arterial blood gas are two methods that measure our oxygen level or SpO2. SpO2 normal reading is typically between 95 to 100 percent. Below normal is called hypoxemia where SpO2 is below 95 percent.

In Covid patients oxygen levels could drop beyond 92% saturation level. For people who tested positive and suffering from mild symptoms as well as some breathlessness, Ministry of Health, Govt of India has announced an approved proning that increases oxygen level to keep patient in safer zone with oxygen above 94%.
