In this article, we will discuss various Causes of Asphyxia. So, let’s get started

Asphyxia refers to an airway obstruction leading to less or non-delivery of atmospheric oxygen to the lungs resulting in carbon-di-oxide retention. Asphyxia can be caused due to mechanical or non-mechanical obstructions.


Mechanical causes

Covering of face (e.g. plastic bag)

Gag or pad smothering (closing of the external respiratory orifice by hand or by other means)


Food or foreign body obstruction (choking)

Throttling (compression of the neck manually)

Hanging or strangulation


Traumatic asphyxia

Non-mechanical causes

Diseases such as Diptheria, infectious mononucleosis, H.influenzae

Rupture of aortic aneurysm in air passages

Hemoptysis in pulmonary tuberculosis

Erosion of bronchus by a tubercular gland

Laryngeal edema because of steam inhalation, ingestion of irritant substances, drug allergies, and poisons

Retropharyngeal edema

Laryngeal or bronchial outgrowths

Non-penetrating injury to the front of the neck
