Fig. 1. Mean ± SD temperatures measured in the sodalime canister at the different examination times in both circuits (closed circles = PhysioFlex apparatus; open circles = valve circuit), decribed as T°infor the probe situated in the lower inflow part and as T°outfor the probe situated in the upper outflow part. The temperature at the Y-piece (T°Y) was also measured with a thermistor. *Intergroup P < 0.05 significance for the specific time assessment.
