of oxygen in the lungs under pressure at the bottom of a deep free-dive. The brain will die after approximately six minutes without oxygen at normal body temperature, but hypothermia of the central nervous system may prolong this. External link in publisher ( help ) GmbH, Emporis. Certain poisonous vapors or gases (as for example in chemical warfare or vomit can have a similar effect. Citation needed After a successful approach, negatively buoyant objects such as a weight belt are removed. 49 Low water temperature can cause ventricular fibrillation, but hypothermia during immersion can also slow the metabolism, allowing a longer hypoxia before severe damage occurs.

New England Journal of Medicine. "Avalon North Station, Boston emporis". The brain cannot survive long without oxygen and the continued lack of oxygen in the blood combined with the cardiac arrest will lead to the deterioration of brain cells causing first brain damage and eventually brain death from which recovery is generally considered impossible. There can be central nervous system damage, cardiac arhythmias, pulmonary injury, reperfusion injury, and multiple-organ secondary injury with prolonged tissue hypoxia. 82 Drowning sex date oslo thai massasje kristiansand
