Abstract: A portable cordless cardiopulmonary arrest recorder is provided by this invention. The arrest recorder is used by the attending personnel at the treatment site for a cardiac-arrest patient. It has multiple chronometers for recording the time and duration of significant events and three sections for recording the patient's rhythm, medication and cardiovert/defibrillation. A visual screen and keyboard for typing additional data is provided. The recorder is designed to manually interface with a central processing unit to transfer data, and recharge the recorder. The recorder subsequently interfaces with a printer and allows for entry of additional information. Optionally the recorder may have provisions for receiving a conventional computer disk capable of storing data which may be interfaced with the central processing unit.
