When did you last check that you did chest compressions exactly at 100 per minute?  Studies have shown that most first aid trainers have healthcare professionals go way too fast!  An audable beep from this simple device ensures that trainers and students do CPR at the correct speed, which is essential for the effectiveness of CPR.

This metronome will fit in the palm of your hand yet can produce a beep that can be easily be heard by the entire class. Volume control and easy to set at 100 beats per minute.

Nigel's tip: Stuides show that coronary perfusion falls significantly if chest compressions are delivered slower than 90 bpm or faster than 120 bpm, so make sure you are teaching your students at the correct speed!
