What term describes the condition of having less blood oxygenated?

The term that refers to the condition of having less blood oxygenated is hypoxemia. Hypoxemia specifically denotes a lower-than-normal level of oxygen in the blood, which can result from various factors such as impaired lung function, altitude, or inadequate oxygen supply.

Hypoxia, on the other hand, is a broader term that describes a deficiency of oxygen in the tissues of the body, which can occur even when blood oxygen levels are adequate. Anoxemia refers to an extreme form of hypoxemia, indicating that there is no oxygen in the blood, while ischemia relates to restricted blood flow, which can lead to insufficient oxygen delivery to tissues but does not inherently indicate low blood oxygen levels alone. Therefore, in the context of describing a condition where blood lacks adequate oxygenation, hypoxemia is the most accurate term to use.
