Illustration of hemodynamic benefits of 40-ml counterpulsation device (CPD) device in calf with diminished cardiac function (DCF). The CPD is operating in 1:2 mode, where every other beat the CPD provides counterpulsation. As indicated by arrows, the CPD increases aortic diastolic pressure (AoP), descending aortic flow (AoF), and diastolic coronary artery flow (CAF). The CPD also decreases afterload, as seen by dotted lines and downward arrow in the AoP waveform.
