Abstract: A method for augmenting blood flow in a limb that is wrapped with a sleeve having at least one chamber for applying compression to the limb in a region generally underlying the chamber includes pressurizing the chamber to a first compression pressure and then reducing the pressure to a refill pressure. Pressure in the chamber is then sensed to determine a first venous refill time. The preceding steps are repeated a second and other times using second and other compression pressures that are different from the first compression pressure and from each other to determine second and other venous refill times. A customized compression pressure is determined by locating the compression pressure at which blood flow out of the region generally underlying the chamber is maximized by finding compression pressure at a maximum venous refill time. A compression device employing such a method is also disclosed.

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.
