摘要: 目的:观察机械通气时不同水平的呼气末正压通气(postive end-exp iratory pressure,PEEP)对中心静脉压(central venouspressure,CVP)的影响。方法:监测10例实施机械通气的呼吸衰竭患者在不同水平PEEP(0~14 cmH2O)时的CVP,分析CVP与PEEP的相关性。结果:不同水平PEEP时CVP有统计学意义(P<0.01);CVP与PEEP呈显著正相关(r=0.989)。结论:CVP随PEEP的上调而增加。Abstract: Objective: To observe the effect of positive end-expiratory pressure(PEEP) on central venous pressure(CVP) of patients undergoing mechanical ventilation.Methods: CVP of 10 patients with respiratory failure undergoing mechanical ventilation at different levels of PEEP(0~14 cmH2O) were monitored.Results: There were increases of CVP accompanied with PEEP increment,and there was a significant positive correlation between CVP and PEEP.Conclusions: PEEP and CVP is significantly correlated.
