This value-priced trainer features 8 pre-programmed scenarios that simulate a variety of cardiac arrest situations. All scenarios can be taught in either English or Spanish. The full-function remote control allows the instructor to easily control the rescue scenarios and pause the session when review or discussion is necessary. The remote uses 2 AAA batteries (not included). An audible metronome assists with the pacing of the CPR chest compressions. The trainer is powered by 3 AA batteries (not included), or can be plugged in using the included AC adapter. A line out port allows the instructor to plug in external speakers.
