Blood oxygen levels can be checked by withdrawing blood from an artery in the wrist, elbow, or groin. Whats more, pulse oximeters can be used continuously and, therefore, can provide long-term monitoring of a persons blood oxygen levels. Any respiratory failure leads to a decrease in saturation, so the level of oxygen in the blood is not a diagnostic criterion in determining coronavirus. During sleep, an elderly persons saturation (the level of oxygen saturation in the blood) drops till 92/93 %. In some people, the right thumb may also work well.
