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, 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]
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.
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily ...
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 include tumors of the upper respiratory tract (oral cavity, pharynx ...
A cricothyrotomy (also called cricothyroidotomy) is an incision made through the skin and cricothyroid membrane to establish a patient airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema, or massive facial trauma.
An airway obstruction can be caused by either an intraluminal mass such as a tumor or a foreign body. [31] The presence of an airway obstruction leads to a cycle of inflammation. [3] It is important to identify the presence of an obstruction because surgical resection is often curative if obstruction is the cause. [32] In adults, foreign body ...
