AED and CPR equipment assists with restoring heart rhythm in the event of cardiac arrest or abnormal heartbeat. AEDs transmit an electric shock to reset proper heart rhythm. AED storage cabinets and cases keep defibrillators and supplies organized and ready for use. AED and CPR training equipment assists with learning and practicing lifesaving measures to build the necessary skills and confidence to perform during an emergency. CPR masks and shields protect rescuers from contact with body fluids during CPR. Automated CPR devices stand in for fatigued rescuers or in the absence of trained rescuers.
