The recommended rate of compressions for adults during CPR is between 100 to 120 compressions per minute. This rate is optimal for maintaining blood flow to the brain and other vital organs during cardiac arrest. Research has shown that compressions within this range are effective in supporting circulation during resuscitation, improving the chances of survival and favorable outcomes post-cardiac arrest. Performing compressions at a rate of 100 to 120 per minute ensures that the chest is compressed sufficiently and at a frequency that allows for adequate blood flow. It's crucial to sustain this tempo consistently throughout the resuscitation process, as interruptions can decrease the effectiveness of CPR. Additionally, this compression rate corresponds well with the rhythm of common songs, such as "Stayin' Alive" by the Bee Gees, which can help rescuers keep time while performing compressions. In contrast, significantly lower or higher rates of compressions can lead to inadequate circulation. For instance, a rate of 60 to 80 compressions per minute would be too slow to provide effective support for the heart and brain. Rates exceeding 120 compressions per minute might lead to diminished blood flow due to inadequate time for the heart to refill between compressions. Thus, adhering to the
