Canadian Red Cross Basic Life Support (BLS) Practice Test

Question: 1 / 400

How fast should you perform chest compressions in CPR?

60 to 80 compressions per minute

100 to 120 compressions per minute

Performing chest compressions at a rate of 100 to 120 compressions per minute is crucial for delivering effective cardiopulmonary resuscitation (CPR). This rate has been established by guidelines from leading organizations, including the American Heart Association and the Canadian Red Cross, as it is optimal for maintaining blood flow to vital organs during cardiac arrest.

The rationale behind this specific compression rate is that it helps to maximize the return of spontaneous circulation (ROSC) by delivering enough blood to the heart and brain. Chest compressions that are too slow may not produce adequate blood flow, while compressions that are too fast can hamper the effectiveness of blood circulation and may lead to incomplete chest recoil, which is necessary for allowing the heart to fill between compressions.

Overall, maintaining the correct compression rate is essential for improving the likelihood of survival and achieving better outcomes in patients experiencing cardiac arrest.
