Abstract:
1. A method for activating an intra-aortal balloon pump (IABP) comprising: (a) calculating the curve of the blood flow rate D(t) in the aorta from the curve of the arterial blood pressure signal P(t) and determining from the curve of the blood flow rate D(t) in each cardiac cycle the time at which an incisura point lies, wherein the incisura point is determined from a first local minimum in the curve of the blood flow rate D(t) after the beginning of an ejection phase; (b) delivering a first signal when the incisura point is reached, wherein said first signal activates an intra-aortal balloon pump (IABP) to inflate; and (c) delivering a second signal at the beginning of the ejection phase, wherein said second signal activates an intra-aortal balloon pump (IABP) to deflate.
