Abstract

Colloid oncotic pressure (COP), pulmonary artery wedge pressure (WP), and the COP-WP gradient were measured in seven critically ill adult patients and compared with extravascular lung water determined using the thermal-dye double-indicator dilution technique and a bedside lung water computer. Correlation coefficients for changes in extravascular lung water vs. COP, WP, and COP-WP were not significant, and in this patient population the COP-WP gradient did not predict changes in extravascular lung water.

摘要

对7例成年危重症患者测量了胶体渗透压(COP)、肺动脉楔压(WP)以及COP-WP梯度,并与采用热染料双指示剂稀释技术和床边肺水计算机测定的血管外肺水进行比较。血管外肺水变化与COP、WP和COP-WP之间的相关系数无统计学意义,在该患者群体中,COP-WP梯度不能预测血管外肺水的变化。
