Pulmonary aspiration
Pulmonary aspiration[edit | edit source]
Pulmonary aspiration is the entry of material (such as phlegm, food or drink, or stomach contents) from the oropharynx or gastrointestinal tract into the larynx (voice box) and lower respiratory tract, the portions of the respiratory system from the trachea (windpipe) to the lungs. A person may either inhale the material, or it may be delivered into the tracheobronchial tree during positive pressure ventilation. When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the wrong pipe."

Causes[edit | edit source]
Consequences of pulmonary aspiration range from no injury at all, to chemical pneumonitis, to lung abscess, to acute respiratory distress syndrome (ARDS). The risk of pulmonary aspiration is relatively high in individuals with a reduced level of consciousness (as a result of intoxication or anaesthetic). In healthy adults, the risk of aspiration is lowest when a person is sitting or standing and awake.
Symptoms[edit | edit source]
Symptoms of pulmonary aspiration include coughing, wheezing, fever, shortness of breath, rapid breathing, chest pain, and a bluish coloration of the skin (cyanosis).
Diagnosis[edit | edit source]
Diagnosis of pulmonary aspiration is based on patient history and often confirmed by physical examination and chest x-ray.
Treatment[edit | edit source]
Treatment for pulmonary aspiration depends on the severity of the condition and the symptoms. It may include antibiotics for bacterial infections, bronchodilators for wheezing, oxygen therapy for low oxygen levels, and in severe cases, mechanical ventilation.
Prevention[edit | edit source]
Prevention strategies for pulmonary aspiration include maintaining good oral hygiene, avoiding over sedation, proper positioning of the body during and after eating, and specific interventions by healthcare professionals such as speech therapists and occupational therapists.
