Oxygenation and Ventilation | COVID-19 Treatment Guidelines

2020-12-17· Goal of Oxygenation. The optimal oxygen saturation (SpO 2) in adults with COVID-19 is uncertain.

Regarding the potential harm of maintaining an SpO 2 <92%, a ...

Your Guide to Masks | CDC

2021-06-29· The CO2 escapes into the air through the mask when you breathe out or talk. CO2 molecules are small enough to easily pass through mask material. In contrast, the respiratory droplets that carry the virus that causes COVID-19 are much larger than CO2, so they cannot pass as easily through a properly designed and properly worn mask.

In the real world, the average mask user without preexisting respiratory illness has nothing to worry about — except COVID-19. Only ...
