acute hypoxia, a sudden or rapid depletion in available oxygen at the tissue level. The condition may result from asphyxia, airway obstruction, acute hemorrhage, blockage of alveoli by edema or infectious exudate, or abrupt cardiorespiratory failure. Clinical signs may include hypoventilation or hyperventilation to the point of air hunger and neurological deficits ranging from headache and confusion to loss of consciousness. Compare chronic hypoxia.
