suffocation: a life-threatening condition in which oxygen is prevented from reaching the tissues by obstruction of or damage to any part of the respiratory system. Drowning, choking, and breathing poisonous gas all lead to asphyxia. Unless the condition is remedied by removing the obstruction (when present) and by artificial respiration if necessary, there is progressive cyanosis leading to death. Brain cells cannot live for more than about four minutes without oxygen.
