title: A comparison of oesophageal and central venous pressures in the measurement of transpulmonary pressure change.
abstract: Oesophageal (oes) and central venous pressure (CVP) were compared as indices of transpulmonary pressure change (deltap). The mean increase of deltaPoes over deltapCVP was 2.8 cm H2O. The size and 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.
