(as-fik'se-a) [ ¹an- + Gr. sphyxis, pulse]
An insufficient intake of oxygen. asphyxial (-se-al), adjective


Extrinsic causes include choking, toxic gases, exhaust gas (principally carbon monoxide), electric shock, drugs, anesthesia, trauma, crushing injuries of the chest, compression of the chest, injury of the respiratory nerves or centers, diminished environmental oxygenation, and drowning.

Intrinsic causes include hemorrhage into the lungs or pleural cavity, foreign bodies in the throat, swelling of the airways, diseases of the airways, ruptured aneurysm or abscess, edema of the lung, cardiac deficiency, tumors such as goiter, and pharyngeal and retropharyngeal abscesses. Other causes include paralysis of the respiratory center or of respiratory muscles, anesthesia, pneumothorax, narcotic drugs, electrocution, and child abuse.


In general, symptoms range in severity from dyspnea, palpitations, and impairment of consciousness, to coma, seizures, permanent brain injury, and death.

autoerotic asphyxia

Autoerotic hypoxia.

fetal asphyxia

Asphyxia occurring in a fetus. It results from interference in placental circulation, umbilical cord compression, or premature separation of the placenta, as in abruptio placentae.

local asphyxia

Asphyxia affecting a limited portion of the body (e.g., fingers, hands, toes, or feet) due to insufficient blood supply. It is a symptom usually associated with Raynaud's disease.

asphyxia neonatorum

A dated term for respiratory failure in the newborn.

asphyxia pallida

An obsolete term for asphyxia in which difficulty in breathing is accompanied by weak and thready pulse, pale skin, and absence of reflexes.

sexual asphyxia

Autoerotic hypoxia.

In the first of two studies which investigated whether the initial PetCO2 measurement at pre- hospitalization CPR might provide an indicator for survival only one case with PetCO2 value below10 mmHg out of 127 survived and none out of139 cases in the second study.1516 According to our results none of the patients with PetCO2 value below 14 mmHg survived.In the study by Grmec et al the pre-hospital PetCO2 levels of 44 asphyxial cardiac arrest patients (in PEA or asystole) and 141 primary cardiac arrest patients (in VF or pulseless VT) were compared.16They found PetCO2 values measured during the1st minute of CPR in the cardiac arrest group and suggested that arrest etiology may be differentiated on the basis of 1st minute values.
Kinney asserted that the abnormality prevents the brainstem from responding to the asphyxial challenge and waking.
