Abstract
A mechanical CPR device having one or more of a piston, a driving component configured to extend the piston toward a patient's torso and retract the piston away from the patient's torso, a controller configured to control the driving component to at least compress the patient's torso by extending the piston from a reference position to a depth and retracting the piston from the depth to the reference position, and a contact member such as one or more of a pressure pad and a suction cup attached to the end of the piston. The contact member can include a semi-adhesive material that has low adhesiveness when the controller controls the driving component to compress the patient's torso less than 60 times per minute and high adhesiveness when the controller controls the driving component to compress the patient's torso more than 60 times per minute.
