What is desaturation used for?

How do you manage desaturation?
In the face of persistent desaturation, management should consist of hand ventilation with 100% oxygen, completion of COVER ABCD-A SWIFT CHECK, and a return to a supine posture. Blood gases, chest radiography, and bronchoscopy may be required where desaturation is persistent and/or no apparent causes can be found.
Why does oxygen drop with Covid?
Using a computational lung model, Herrmann, Suki, and their team tested that theory, revealing that for blood oxygen levels to drop to the levels observed in COVID-19 patients, blood flow would indeed have to be much higher than normal in areas of the lungs that can no longer gather oxygen—contributing to low levels of …

What is normal oxygen desaturation?
At sea level, a normal blood oxygen level (saturation) is usually 96 – 97%. Although there are no generally accepted classifications for severity of oxygen desaturation, reductions to not less than 90% usually are considered mild. Dips into the 80 – 89% range can be considered moderate, and those below 80% are severe.

What happens when someone desaturated?
Oxygen desaturation (low oxygen saturation) means that the percentage of oxygen in your blood is lower than it should be. Low oxygen saturation is one of the indicators that you could be at risk of long-term health consequences, such as cardiac (heart) disease and dementia.
