What term describes depressed oxygen levels in the blood?

Hypoxia describes a state where tissues aren’t getting enough oxygen. It isn’t about air movement or breathing mechanics itself, but about the end result: despite whatever air intake is happening, the body's cells are starved of oxygen. This can happen if there’s not enough oxygen in the blood (hypoxemia), or if blood flow to tissues is poor, or if oxygen use at the cellular level is impaired. In practical terms, recognizing hypoxia means you understand that oxygen delivery to tissues is insufficient and you need to improve oxygen delivery, often with supplemental oxygen and ensuring adequate ventilation and perfusion. The other terms describe processes or conditions not defined by a current lack of oxygen in the tissues: respiratory arrest is a stopping of breathing, ventilation is the act of moving air in and out, and respiratory failure is a broader state where gas exchange can no longer be maintained. So the best term for the described situation is hypoxia.
