| Abstract: | Seventeen patients undergoing middle abdominal operation were studied with control ventilation in general anesthesia. The change of inhale and end tidal O2 concentration difference (I-EtO2 ) was observed and compared with end tidal CO2 (PetCO2 ) while pulmonary ventilation was decreased. The results showed:as the tidal volume(VT)decreased, I-EtO2 and PetCO2 increased. Compared with control value, when VT decreased 20% ~50% , I-EtO2 was markedly increased; while VT decreased 30% ~50% ,PetCO2 was dramatically elevated. Multiple linear regression analysis, used VT as dependent variance and I-EtO2 , PerCO2 as independent variance,found that the standard partial regression coefficient was:b1 (I-EtO2 ) = 0.1875,b2(PetCO2) = 0.1573 and Y = 0.187 5X1 0.157 3X2. It suggested that I-EtO2, can be used in monitoring the pulmonary ventilation, which was more sensitive than PetCO2 in reflecting the decrease of pulmonary ventilation. |
