Choking, also known as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract. An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation .
The causes of upper airway obstructions can be acute or chronic. Acute causes of upper airway obstruction include foreign body aspiration, blunt trauma to the neck, infection, and swelling due to allergies or other inflammatory conditions. [3] In children, viral infections such as croup or epiglottitis are frequent causes. [4]
Nasal blockage may easily lead to upper airway obstruction in infants. For other ages, upper airway obstruction may occur from a foreign body or edema of the pharynx, larynx, or trachea. In cases of decreased or total loss of consciousness, the tongue can lose muscle tone and obstruct the upper airway. [2] Other potential causes of obstruction ...
Airway obstruction is commonly caused by the tongue, the airways itself, foreign bodies or materials from the body itself, such as blood or vomit. [ 2 ] Contrary to advanced airway management , basic airway management technique do not rely on the use of invasive medical equipment and can be performed with less training.
Airway obstruction can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents . [citation needed] Airway management is commonly divided into two categories: basic and advanced.
Actual or impending airway obstruction is a common indication for intubation of the trachea. Life-threatening airway obstruction may occur when a foreign body becomes lodged in the airway; this is especially common in infants and toddlers.
The most common complication from a foreign body aspiration is a pulmonary infection, such as pneumonia or a lung abscess. [7] This can be more difficult to overcome in the elderly population and lead to even further complications. Patients may develop inflammation of the airway walls from a foreign body remaining in the airway. [2]
Choking occurs when a foreign body obstructs the trachea. Rescuers should only intervene in patients who show signs of severe airway obstruction, such as a silent cough, cyanosis, or inability to speak or breathe. If a patient is coughing forcefully, rescuers should not interfere with this process and encourage the patient to keep coughing.
