How many cycles of CPR should you perform before re-evaluating the situation?

To ensure effective CPR, it is recommended to perform approximately 5 cycles, which typically takes about 2 minutes, before pausing to re-evaluate the situation. This timeframe is based on the understanding that high-quality chest compressions are crucial for maintaining cerebral and coronary perfusion during a cardiac arrest.

After approximately 5 cycles, you should check for any signs of life, assess the need for continued resuscitation efforts, and modify your approach based on the patient's response or any changes in the situation. This is essential for making informed decisions about the next steps, such as calling for advanced help or utilizing an Automated External Defibrillator (AED) if available.

While other options suggest different numbers of cycles, 2 minutes is considered the optimal duration for providing compressions without interruption to maintain the efficacy of CPR and to assess the patient's condition adequately afterward.
