asphyxia

 [as-fik´se-ah]
pathological changes caused by lack of oxygen in respired air, resulting in a deficiency of oxygen in the blood (hypoxia) and an increase in carbon dioxide in the blood and tissues (hypercapnia). Symptoms include irregular and disturbed respirations, or a complete absence of breathing, and pallor or cyanosis. Asphyxia may occur whenever there is an interruption in the normal exchange of oxygen and carbon dioxide between the lungs and the outside air. Some common causes are drowning, electric shock, hanging, suffocation, lodging of a foreign body in the air passages, inhalation of smoke and poisonous gases, and trauma to or disease of the lungs or air passages. Treatment includes immediate remedy of the situation by artificial respiration and removal of the underlying cause whenever possible. See also suffocation. adj., adj asphyx´�ial, asphyx´iant.

as·phyx·i·a

(as-fik'sē-ă),
Impaired or absent exchange of oxygen and carbon dioxide on a ventilatory basis; combined hypercapnia and hypoxia or anoxia.
[G. a- priv. + sphyzō, to throb]

asphyxia

(ăs-fĭk′sē-ə)
n.
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.

asphyxia

Physiology
1. Impaired breathing.
2. A pathological state caused by the inadequate intake of O2, with accumulation of CO2 and hypoxia. See Autoerotic asphyxia, Sexual asphyxia.

as·phyx·i·a

(as-fik'sē-ă)
Impairment of ventilatory exchange of oxygen and carbon dioxide; combined hypercapnia, hypoxia, or anoxia; causes death if not corrected.
[G. a- priv. + sphyzō, to throb]

asphyxia

Suffocation by interference with the free AIRWAY between the atmosphere and the air sacs in the lungs. Asphyxia is usually the cause of death in drowning, choking, strangling, inhalation of a gas which excludes oxygen, foreign body airway obstruction and OEDEMA of the LARYNX.

asphyxia

suffocation, lack of oxygen.

Asphyxia
