A control system for an inflatable chamber on a patient's aorta monitors (402, 412) an actual flow duration time for inflating or deflating the chamber with a volume of pressurized fluid from reservoirs, and compares (404, 416) the actual time with a target time. If the actual inflation time is too short with respect to the target time, the pressure is decreased (408), and if too long the pressure is increased (410). Also, if the actual deflating time is too short with respect to the target time, the vacuum is decreased (418), and if too long, the vacuum is increased (420). The change in either of the pressure sources is varied (422-428) until the desired value is reached within the reservoirs. |
