Abstract: An aid for cardio-pulmonary resuscitation comprises a flat disc having a lower surface coated with an adhesive suitable for application to the skin of a patient, the adhesive being covered by a removable film to allow the adhesive to be activated. The upper surface of the disc is covered by a moisture absorption layer and includes a peripheral rib. The size of the upper surface is sufficient just to receive the forward part of the palm of the operative and the forward rib is arranged to lift the fingers of the operative away from the patient's skin. The device is positioned at the start of the resuscitation process at the landmark position and remains in place during the process.
