Community Acquired Pneumonia in a 66-Year-Old Male Patient with Mild Hipoxia

Abstract

Community-Acquired Pneumonia (CAP) remains a significant cause of morbidity and mortality among geriatric patients in primary care settings due to atypical presentations and rapid progression. A 66-year-old male presented with a 2-day history of worsening shortness of breath, high fever, productive cough, and nausea. Physical examination revealed tachypnea (24 breaths/min), mild hypoxia (SpO₂ 91% on room air), dry oral mucosa, and bilateral coarse crackles. He was diagnosed with CAP accompanied by mild hypoxia and risk of dehydration. Standard management at the emergency unit included oxygen supplementation via nasal cannula, intravenous fluid resuscitation, bronchodilator nebulization, and antipyretics. Prompt identification using clinical criteria and risk
stratification, such as the CURB-65 score, is essential in primary care to guide appropriate treatment levels and empiric antimicrobial therapy for elderly patients with CAP
