The rhythm challenge
Can you hold the rhythm?
Chest compressions run at 100 to 120 a minute. We count you in, then the beat stops and you keep it going for 120 seconds.
Tap anywhere in the box, or press the spacebar. Nothing is recorded or sent anywhere.
Follow the beat
Then the beat stops.
Keep going. Tap anywhere.

Your rate is the part you can hold. In a real cardiac arrest it is the depth that goes instead, and the rescuer cannot feel it happening. That is why we swap every two minutes.
In a real cardiac arrest a defibrillator or the 111 call-taker may count the beat for you. Without one, this is what happens.
This measures rhythm only, which is the easy half. Depth is the half that fails, and you cannot practise it on a screen. That takes a course.
