What does hypoxia refer to?

Hypoxia refers specifically to a lack of adequate oxygen supply to the body's tissues. When an individual is hypoxic, their blood and organs do not receive enough oxygen to function properly, which can lead to serious physiological problems. This condition can arise from various causes such as high altitudes, respiratory illnesses, or environmental factors that impede oxygen absorption. Understanding hypoxia is crucial in tactical combat situations, as it can affect a casualty's ability to survive and respond to treatment, necessitating immediate intervention to restore proper oxygen levels in the body.
