Abstract: A resuscitation device having a specific frame design with an integrated hydraulic plunger frame which is adapted to be strapped over a patient's chest. The frame is designed with two protruding arms stretching towards the patient's armpits. The frame includes flexible straps coiled onto spring biased rotatable reels. The straps end in respective armpit stays which are looked into recesses in a back support. The plunger of the frame stops against a limiting means which limits the travel of the plunger automatically according to the size of the patient's chest.
