What is the minimum oxygen level for COVID-19 patients?

The optimal oxygen saturation (SpO2) in adults with COVID-19 who are receiving supplemental oxygen is unknown. However, a target SpO2 of 92% to 96% seems logical, considering that indirect evidence from patients without COVID-19 suggests that an SpO2 of <92% or >96% may be harmful.

Why would you need a ventilator in the context of the COVID-19 pandemic?

When your lungs inhale and exhale air normally, they take in oxygen your cells need to survive and expel carbon dioxide. COVID-19 can inflame your airways​​​​​​​ and essentially drown your lungs in fluids.

A ventilator mechanically helps pump oxygen into your body.
