Abstract
IABP can be utilized not only as a useful treatment modality but also as a diagnostic tool, so the following analysis was carried out using aortic pressure waveform recorded through the IABP catheter in 10 patients. 1. Cardiac output estimation by a Pulse-Contour Method; The correlation was well (R=0.91) within 12 hours from the calibration. 2. Evaluation of cardiac contractility by determining the peak pressure change (ΔP) and stroke volume change (ΔV) at the point of abrupt cessation of IABP (theoretically ΔP/ΔV represents Emax); When cardiac function was poor (SWI<30gm/M2(PAw≥15mmHg, SWI<20gm/M2(PAw<15mmHg), the ΔV was larger.
