In this study we prospectively investigated the prognostic significance of first arterial CO 2 tension in patients hospitalized with CAP. Methods: In this prospective study patients with CAP, admitted to a general hospital were included. PaCO 2 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 PaCO 2 and mortality (P=0.544) or ICU admission (P=0.863). However advanced age, associated CHF, high BUN levels, high CURB-65 scores, associated pleural effusion in chest X-ray and being admitted to the ICU (P=0.012, 0.004, 0.003, Conclusions: There was less prominent prognostic value regarding on-admission PaCO 2 in comparison to other factors such as CURB-65. Considering the inconsistent results of surveys conducted on prognostic value of PaCO 2 for CAP outcomes, further investigations are required to reach a consensus on this matter.
