Educational content only — not medical advice.
Anatomy
High remittent fever with shaking chills, productive cough with rust-colored sputum, pleuritic chest pain aggravated by inspiration, tachypnea.
Action
Pathogen inhalation triggers inflammatory cascade characterized by alveolar congestion, red hepatization, and gray hepatization, leading to severe ventilation-perfusion mismatch.
Clinical notes
Diagnosed via chest radiograph (consolidation) and sputum culture. Severity stratified by CURB-65 score to guide outpatient vs ICU antibiotic therapy.
