The method of delivering chest compressions remains the same, as does the rate (at least 100 per minute). It is hoped that the use of compression-only delivery will increase the chances of the lay public delivering CPR.
Much like when crack your knuckles, loud popping noises from your knees are most likely caused by what is called cavitation. Cavitation results from a change in joint pressure that allows carbon dioxide, which is normally dissolved in your joint fluidâa.k.a.
However, if youâre not in the habit of cracking your joints and you still hear an unusual popping sound, it might not be due to your joints cracking at all. Such noises may also come from your tendons, which keep your muscles attached to your bones, and ligaments, which connect your bones.
