Effect of positive end-expiratory pressure on central venous pressure of the patients undergoing mechanical ventilation

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.
