Something which blocks the air passages.
Blockage of any portion of the respiratory tract; usually with reference to the upper tract. When complete, airway obstruction may be life- threatening and is treated with the Heimlich maneuver.
The constriction or occlusion of the respiratory passages, which can impede the normal flow of air. This obstruction may arise from various factors, including the presence of a foreign object, such as a food particle, that becomes lodged in a segment of the upper airway, potentially leading to choking. Furthermore, certain diseases and disorders, such as diphtheria and lung cancer, have the potential to cause blockages in the air passages. Additionally, the spasm of the muscular walls of the airway, as observed in bronchospasm, a characteristic feature of asthma and bronchitis, can result in breathing difficulties.
