It is recommended to initiate oxygen therapy when the SpO2 levels drop below 90-92% . Try to avoid nasal oxygen due to aerosol spread and use masks instead.

In adults with COVID-19 and acute hyperemic respiratory failure on oxygen, it is recommended that SpO2 be maintained no higher than 96%.

A recent study from China showed that approx. 41% of all patients who were hospitalized with COVID-19 needed supplementary oxygen.
