【摘要】目的 探讨ICU严重肺部感染行机械通气患者床头抬高的不同角度对中心静脉压的(CVP)影响。方法 选取ICU收治的严重肺部感染致呼吸衰竭行机械通气患者48例，按照患者收治顺序随机均分为对照组和观察组各24例。观察组患者取平卧位，对照组患者取平卧位下自15°递增至60°分四个水平抬高床头。观察比较两组患者CVP值及HR、MAP及SpO2参数。结果 观察组CVP值明显高于对照组四个角度CVP值，对照组四个不同抬高床头水平的CVP值依次递减，卧位角度越大相应的CVP值越小；差异有统计学意义(P<0.05)。经监测两组患者HR、MAP及SpO2参数，差异无统计学意义(P>0.05)。结论 ICU严重肺部感染行机械通气患者床头抬高的不同角度均影响其CVP 值，病情危重患者在测量CVP时应尽量保持原

    【Abstract】Objective To investigate the effect of different angles of the bedside elevation on central venous pressure (CVP) in patients with severe pulmonary infection in ICU.Methods Forty-eight patients with respiratory failure were randomly divided into control group and observation group(24 cases)according to the order of patients treated with ICU. The patients in the observation group were given supine position. In the control group ......
