Abstract: Methods to control the delivery of CPR to a patient through a mechanical CPR device are described. The method generally allows for a gradual increase in the frequency of CPR cycles. The gradual increase can be regulated by protocols programmed within the CPR device such as intermittently starting and stopping the delivery of CPR, accelerating the delivery of CPR, stepping up the CPR frequency, increasing the force of CPR, and adjusting the ratio of compression and decompression in a CPR cycle. Combinations of each of these forms may also be used to control the delivery of CPR. This manner of gradually accelerating artificial blood flow during the first minutes of mechanical CPR delivery can serve to lessen the potential for ischemia/reperfusion injury in the patient who receives mechanical CPR treatment.
