Silent Hypoxia-1

•It is a form of oxygen deprivation that is harder to detect than regular hypoxis because patients appear to be less in distress.
•Covid pneumonia, a serious medical condition found in severe Covid-19 patients, is preceded by silent hypoxia.
•Many Covid-19 patients with oxygen levels below 80% look at ease and alert. There have been a few cases of oxygen levels below 50% as well.
