Typically, rescuers aim to perform five cycles of CPR in 2 minutes.
This is based on the standard CPR guidelines, which recommend a compression rate of 100-120 compressions per minute and a compression-to-ventilation ratio of 30:2. One cycle of CPR consists of 30 chest compressions followed by 2 rescue breaths.
Therefore, to achieve five cycles within two minutes, rescuers need to:
-
Maintain a Consistent Compression Rate: Aim for 100-120 compressions per minute. This ensures adequate blood flow to the vital organs.
-
Deliver Effective Breaths: Each breath should last approximately one second and create a visible chest rise. Avoid excessive ventilation.
-
Minimize Interruptions: Interruptions in chest compressions significantly reduce the effectiveness of CPR. Try to keep interruptions as brief as possible. This is why rescuers should swap every 2 minutes to minimize rescuer fatigue. After 2 minutes and five cycles, swap rescuers to ensure optimal compressions.
| Action | Description |
|---|---|
| Compression Rate | 100-120 compressions per minute |
| Compression Depth | At least 2 inches (5 cm) for adults |
| Compression:Breath Ratio | 30:2 |
| Cycle Duration | Aim for approximately 24 seconds per cycle |
| Number of Cycles | 5 cycles in 2 minutes |
Performing five cycles of CPR in two minutes is crucial for maximizing the chances of survival for a person experiencing cardiac arrest. Adhering to the recommended compression rate, depth, and minimizing interruptions are essential elements of effective CPR.
