Objectives: Pneumonia is a common infection, especially in older patients with comorbidities. This study aimed to assess outcome severity scores and arterial blood gas parameters in adult pneumonia patients in the emergency. Methods: 112 adult patients (?18 years) with pneumonia were prospectively enrolled at a tertiary center between March–December 2024. Data included demographics, comorbidities, vitals, lab tests, CURB-65 and PSI scores. Arterial blood gases (pH, PaCO?, HCO?) were evaluated by ROC analysis for prognostic value. Results: Mean age was 69.4 years; 86.6% had chronic disease. Mean CURB-65 was 1.40; most patients were in PSI stage IV–V. Oxygen therapy was applied to 73.2%, vasopressors to 54.5%. ROC analysis showed pH cutoff of 7.35 predicted PSI I–III with 80.4% sensitivity, 50.8% specificity (p=0.007). HCO? cutoff 24.20 predicted CURB-65 <2 with 62.3% sensitivity (p=0.031). Low pH and HCO? values were strongly associated with severity. Conclusion: Combining CURB-65 and PSI with pH and HCO? values may enhance severity assessment and support clinical decisions in emergency pneumonia cases.
