Hypoxemia Causes, Symptoms, and Treatments

1Hypoxemia Overview

Oxygen is essential for lives. People breathe in air through their noses and draw air into their lungs. Red blood cells carry oxygen out from the lungs and deliver it to other parts to ensure normal body function. Organs like the brain and liver would be damaged when there is no sufficient oxygen. The oxygen level range of a normal person is from 95% to 100%, and hypoxemia happens when people have a below-normal oxygen saturation in the blood. Hypoxemia can also result in hypoxia, which is a decreased level of tissue oxygenation. Though the two terms are similar in spellings, they are different in nature. In brief, hypoxemia is a low oxygen content in the blood, whereas hypoxia refers to the low oxygen content in tissue cells. [1]
