What is pneumonia oxygen level?

The present study suggests that in acutely infected nursing home patients, a decrease in oxygen saturation of >3% from baseline, as well as a single oxygen saturation of <94, should suggest pneumonia. A decrease from baseline of <4% or a single oxygen saturation of 94 or higher suggests that pneumonia is unlikely.
