What does hypoxia refer to?

Hypoxia refers to a state where there is an insufficient supply of oxygen to the tissues and organs of the body. This condition can arise from various causes, such as respiratory issues, inadequate oxygen in the environment, or circulatory problems. When the body or a region of the body does not receive enough oxygen, it cannot function properly, potentially leading to serious health consequences. Understanding hypoxia is critical in basic life support, as it helps in recognizing when someone may require immediate intervention, such as supplemental oxygen or ventilation support. The other options describe different medical conditions or effects, but they do not accurately define hypoxia.
