The result is that oxygen molecules in the air are further apart, reducing the oxygen content of each breath incrementally as one goes up in altitude. For this reason, they are used by clinical staff in all settings both in the hospital and in the community, as well as by many people in their own homes. When this happens, it's called hypoxia. If youre experiencing symptoms of COVID-19, contact your healthcare provider as soon as possible. Oxygen saturations less than 92% are associated with major adverse events in outpatients with pneumonia: a population-based cohort study. For example, with chronic conditions such as COPD and asthma, the cause of hypoxia is usually low air exchange in the lungs and alveoli. An ABG value refers to the levels of oxygen and carbon dioxide in blood running through your veins. The oxygen that we breathe in then gets absorbed through the lining of our lungs into our bloodstream.
