Airway obstruction is a condition that occurs when airflow is impeded in the airway, which can lead to breathing difficulties. This condition can be caused by a variety of factors such as a foreign body in the airway, airway narrowing due to inflammation or edema, mucus buildup in the airway, or upper airway obstruction due to sleep apnea. Airway obstruction is a potentially dangerous situation that can cause serious complications, such as asphyxia, hypoxia, or cardiac arrest. It requires immediate medical intervention to avoid potentially life-threatening complications.
Definition and Meaning
Airway obstruction is a condition where airflow is blocked in the airway, causing difficulty in breathing. This can be caused by a foreign body, tissue swelling or mucus build-up. This condition is potentially dangerous and requires immediate intervention to avoid serious complications.
The weight of the tongue
The weight of the tongue pushing back the epiglottis causing closure and obstruction of the larynx in the unconscious victim who is lying on his back. This mechanism is common in persons with impaired consciousness.
Swelling of the epiglottis
Swelling of the epiglottis as a result of an inflammatory reaction leading to closure and obstruction of the larynx in a supine victim. This mechanism is common in people with respiratory diseases such as asthma or bronchitis.
A foreign body in the pharynx
The presence of a foreign body in the pharynx that causes it to become obstructed. This mechanism is common in children and people with swallowing disorders.
Swelling of the laryngeal wall
Swelling of the laryngeal wall during an allergic reaction or trauma to the neck leading to closure and obstruction of the larynx. This mechanism is common in people with allergies and victims of neck trauma.
In brief
Airway obstruction can be caused by a variety of mechanisms such as tongue weight, swelling of the epiglottis, a foreign body in the pharynx, or swelling of the laryngeal wall. It is important to consider these different mechanisms in order to quickly diagnose and treat airway obstruction.
