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.
In most cases, this is nothing to be concerned about. In fact, the theory that popping your joints will lead to arthritis has absolutely no support in the research literature. Now some folks will notice a grinding noise in the knee joint when they squat. If it's not painful, itâs categorized as âbenign creptiusâ which, again. is nothing to be concerned about.
