- W2183895384 abstract "SUMMARY Wedescribe a new method for the absolute deter-mination of cardiac output in intra-aortic balloon pumped (IABP)patients. The method uses the known pumping volume ofthe IABPballoon and the radial arterial pressure trace, which is commonlyused to monitor IABP patients, to determinethecardiac output. Two pressure excursions denoted by P,-P0 and P2-P0, characterizing IABP balloondeflation, andventricularejection, respectively, areex- tracted fromthe radial trace. The cardiac output (CO)is then deter-mined by the simple relation: CO = (BV) X (P2-Po)/(P,-P,) X HR where HR is the heart rate, andthevalue for pumpedballoonvolume THE RADIAL ARTERIAL PRESSURE CONTOURwhich is commonly used to monitor intra-aortic balloonpumped (IABP) patients consists ofseveral pulse segmentsrepresenting discrete events in the cardiac cycle: ventricle ejection of blood into the aorta, balloon inflation accom- panied by runoff from the aorta into the arterial tree, and balloondeflation, withtheinflation transient separated" @default.
