Abstract:
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.
