Abstract
A device for operating an intra-aortic balloon pump having an arterial pressure sensor associated therewith for measuring arterial pressure includes a pressure sensor for measuring an internal pressure of the balloon pump and an arrangement for applying a positive pressure in order to provide fluid to the balloon pump for purposes of inflating the ballon pump. An adjustment device is also included for adjusting the zero point of the arterial pressure sensor. The adjustment device compares the arterial pressure measured by the arterial pressure sensor with the internal pressure of the balloon pump as determined by the pressure sensor and adjusts the zero point accordingly to eliminate differences between the arterial pressure and internal pressure.
