Due to progressive nature of the disease the respiratory failure verification is of great importance.Objectives: This study aimed to investigate capnometry indices in patients with stable COPD (GOLD III-IV) compare to healthy subjects.Methods: Bodyplethysmography, capnometry. Data are presented as mean±SD.Results: A total of 87 subjects (age 56.2±1.2 years; 59% male) were enrolled: COPD group (n=42, mean%FEV1 =39.5%), control group (n=45, mean%FEV1 =93.7%). All subjects were performed bodyplethysmography and capnometry, we compared the results between groups.All bodyplethysmography and capnometry indices of COPD subjects were significantly (p<0.05) different from control. The mean values Rtot,% was 241.6±12.7 and 117.7±8.4, IC,% was 81,1±2.2 and 110.9±3.2, RV,% was 189±9 and 101.1±5 in COPD and control group respectively. The capnometry results was Vde%VT 33.8±1.2 and 25.5±1, PECO2, kPa was 2.8±0.1 and 3.2±0.1, end-expiratory lung volume, l was 5.1±0.2 and 4.7±0.2, FeCO2,% was 3.0±0.1 and 3.4±0.1 in COPD and control group respectively.Conclusions: Capnometry might be a useful tool to detect the respiratory failure in COPD patients.
