A comparison of oesophageal and central venous pressures in the measurement of transpulmonary pressure change

Abstract

Summary: Oesophageal (oes) and central venous pressure (CVP) were compared as indices of transpulmonary pressure change (Ap). The mean increase of Apoes over was 2.8 cm H2O. The size and A oes variability of the increase were similar to the expected difference between oesophageal and pleural pressure fluctuations occurring in the supine patient. Central venous pressure may be more accurate and reliable than oesophageal pressure for estimations of transpulmonary pressure change in the supine position. © 1976 Macmillan Journals Ltd.
