Aspiration pneumonia

Aspiration pneumonia is an infectious pulmonary disorder that occurs when colonized oropharyngeal secretions, food, or gastric contents are misdirected into the larynx and lower respiratory tract It primarily affects the lower respiratory system, with elevated vulnerability seen in older adults, hospitalized individuals, and patients with compromised airway defense mechanisms due to dysphagia, neurological impairment, or altered consciousness Pathophysiologically, the aspirated inoculum introduc...

Aspiration pneumonia is an infectious pulmonary disorder that occurs when colonized oropharyngeal secretions, food, or gastric contents are misdirected into the larynx and lower respiratory tract

It primarily affects the lower respiratory system, with elevated vulnerability seen in older adults, hospitalized individuals, and patients with compromised airway defense mechanisms due to dysphagia, neurological impairment, or altered consciousness Defining clinical manifestations typically include fever, productive cough, dyspnea, hypoxemia, and radiographic infiltrates characteristically situated in dependent lung segments

It primarily affects the lower respiratory system, with elevated vulnerability seen in older adults, hospitalized individuals, and patients with compromised airway defense mechanisms due to dysphagia, neurological impairment, or altered consciousness Pathophysiologically, the aspirated inoculum introduces oral and gastric bacteria into the pulmonary parenchyma, provoking acute alveolar inflammation, localized tissue consolidation, and systemic inflammatory signs

Defining clinical manifestations typically include fever, productive cough, dyspnea, hypoxemia, and radiographic infiltrates characteristically situated in dependent lung segments
