Prognostic value of on admission arterial PCO2 in hospitalized patients with community-acquired pneumonia %K %X Background: There is little data about the correlation between the outcome of community acquired pneumonia (CAP) and the hypercapnic type respiratory failure. In this study we prospectively investigated the prognostic significance of first arterial CO2 tension in patients hospitalized with CAP. Methods: In this prospective study patients with CAP, admitted to a general hospital were included. PaCO2 was measured for each subject in an arterial blood sample drawn in the first 2 hours and its correlations with three major outcomes were evaluated: intensive care unit (ICU) admission, duration of admission and mortality in 30 days. Results: A total of 114 patients (mean age: 60.9±18.3; male: 51.8%) diagnosed with CAP were included. Significant relationship was not found between PaCO2 and mortality (P=0.544) or ICU admission (P=0.863).
