The lungs are normally protected against aspiration by a series of protective reflexes such as coughing and swallowing. Significant aspiration can only occur if the protective reflexes are absent or severely diminished (in neurological disease, coma , drug overdose , sedation or general anesthesia ).
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.
Foreign body aspiration occurs when a foreign body enters the airway which can cause difficulty breathing or choking. [1] Objects may reach the respiratory tract and the digestive tract from the mouth and nose, but when an object enters the respiratory tract it is termed aspiration.
A pulmonary agent, or choking agent, is a chemical weapon agent designed to impede a victim's ability to breathe. Such compounds operate by causing a build-up of fluids in the lungs, which then leads to asphyxiation. Exposure of the eyes and skin tends to be corrosive, causing blurred vision and severe deep burns.
They make up the majority of normal oral flora and the presence of putrid fluid in the lungs is highly suggestive of aspiration pneumonia secondary to an anaerobic organism. [14] While it is difficult to confirm the presence of anaerobes through cultures, the treatment of aspiration pneumonia typically includes anaerobic coverage regardless. [14]
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
