Asphyxia

Asphyxia or asphyxiation is a condition of severely deficient supply of oxygen to the body that arises from abnormal breathing. An example of asphyxia is choking. Asphyxia causes generalized hypoxia, which primarily affects the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by an inability of an individual to acquire sufficient oxygen through breathing for an extended period of time. These circumstances can include but are not limited to: the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in ...

  2. The loss of consciousness due to the body's inability to deliver oxygen to its tissues, either by the breathing of air lacking oxygen or by the inability of the blood to carry oxygen. Such asphyxia can be result from the inhalation of non-toxic gases which displace oxygen from the inhaled air, by exposure to carbon monoxide from smoke inhalation such that hemoglobin is poisoned, or the development of methemoglobinemia.
  3. A condition in which an extreme decrease in the concentration of oxygen in the body leads to loss of consciousness or death. The term is now obsolete, having been replace in mid-twentieth century by the more specific terms anoxia, hypoxia, hypoxemia and hypercapnia.
