Abstract
Objective To evaluate the ef ect of dif erent positive end expiratory pressure ( PEEP) on central venous pressure (CVP) in patients with mechanical ventilation. Methods Twenty-eight cases of respiratory failure with mechanical ventilation were enrol ed in this study. Vessel was inserted via subclavian vein or internal jugular vein in every one ,then CVP was measured under dif erent PEEP conditions of 0,3,6,9,12,15cmH2O. Results The CVP value got an increase with a rise of PEEP when it is greater than 3 cmH2O. The linear regression equation Y=9.981+0.485X can be got when taking PEEP as independent variable X and CVP as dependent variable Y. Conclusion When PEEP is greater than 3 cmH2O,it has obvious influence on CVP. The dynamic change of CVP has certain significance to value the change of blood volume and guide the rehydration.关键词
