• A condition in which an extreme decrease in the concentration of oxygen in the body accompanied by an increase in the concentration of carbon dioxide leads to loss of consciousness or death. Asphyxia can be induced by choking, drowning, electric shock, injury, or the inhalation of toxic gases.
  • Originally, absence of pulse.
  • The extreme condition caused by lack of oxygen and excess of carbon dioxid in the blood, brought about by any sufficient interference with respiration, as in choking, drowning, or paralysis of the muscles of respiration. Also <internalXref urlencoded="asphyxy">asphyxy</internalXref>.
  • Apparent death, or suspended animation; the condition which results from interruption of respiration, as in suffocation or drowning, or the inhalation of poisonous or irrespirable gases.
  • The loss of consciousness due to the interruption of breathing and consequent <xref>anoxia</xref>. Asphyxia can be result from choking, drowning, electric shock, injury.
  • 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 <xref>methemoglobinemia</xref>.
  • A condition in which an extreme decrease in the concentration of <xref>oxygen</xref> in the body leads to loss of <xref>consciousness</xref> or death. The term is now obsolete, having been replace in mid-twentieth century by the more specific terms <xref>anoxia</xref>, <xref>hypoxia</xref>, <xref>hypoxemia</xref> and <xref>hypercapnia</xref>.
  • a condition in which insufficient or no oxygen and carbon dioxide are exchanged on a ventilatory basis; caused by choking or drowning or electric shock or poison gas
