cerebral hypoxia

Lack of oxygen supply to the brain, usually as a result of either diminished blood flow (such as in traumatic childbirth or cardiopulmonary arrest) or diminished oxygenation of the blood (such as in high-altitude exposures or patients with advanced cardiopulmonary disease). If nothing is done to treat this condition, irreversible anoxic damage to the brain begins after 4 to 6 min and sooner in some cases. If basic resuscitation measures are begun before the end of this period, the onset of cerebral death may be postponed.

"A number of possible causes have been discounted on evidence which suggest that the cause of death was acute brain hypoxia due to an airway obstructed by laryngeal spasm." She added: "We're still pursuing a civil claim against the trust."
