Abstract

In 15 patients without cardiopulmonary disease, We studied the effects of positive end- expiratory pressure(PEEP) on the deadspace-tidal volume ratio (VD/VT ratio) and total static compliance after induction of anesthesia. PEEP of 0,37+/- and 15 cmH2O were sequentially applied. Mean VD/VT ratio and compliance were 0.34+/-7.11, 57+/-8 m17H70 at zero PEEP, 0.37 +/-0.06, 64+/-6ml/H2O at 10 cmH70 PEBP, 0.43+/-0.16, 59+/-8 ml/cmH2O at 10 cmH2O PEEP and 0.43+/-0.16, 59.8 ml/cmHaO at 15 cm/H20 PEEP At each level of PEEP, VD/VT retie and compliance had increased with elevation of PEEP. VD/VT ratio at 15 cmH20 was signica- ntlr differed from that of utero PEEP but not in compliance. We 77served in anesthetized patients with healthy lung that the ap1ication of PEEP up to 15 omHaO increased VD/VT ratio and compliance.
