摘要 一种新型无创袖带血压测量仪DynaPulse,在测量血压、心输出量等方面具有价值。作者通过DynaPulse与Fick法以及多普勒超声法的对照研究来验证这一无创性心输出量检测法的准确性和可信度。 4 5例住院患者参加DynaPulse与多普勒超声法测量心输出量的对照研究 ;另外 2 6例参加了DynaPulse与Fick法的测量心输出量的对照研究。结果显示 ,DynaPulse与多普勒超声测量的心输出量之间有很好的相关性 (r=0 76 )。DynaPulse测量的心输出量虽然较Fick法测量的值低 ,但两者之间仍有较好的相关性 (r=0 6 1)。Dyna DynaPulse, a newly developed noninvasive apparatus, is valuable in assessing blood pressure, cardiac output and vascular compliance. The purpose of the present study was to evaluate the validity of cardiac output measurement using DynaPulse in patients, compared with echocardiography and Fick method. Forty five inpatients underwent cardiac output measurement using DynaPulse (CO DP ) and Doppler echocardiography (CO DE ), cardiac output was measured with DynaPulse (CO DP ) and Fick method (CO FM ) in additional 26 patients. A good correlation was found between CO DP and CO DE ( r =0 76). There was an acceptable correlation between CO DP and CO FM ( r =0 61). DynaPulse can provide a noninvasive, clinically useful estimation of cardiac output.
