After 8 minutes or 4 cycles what should be done?

High-quality CPR hinges on two things: keeping blood flow with uninterrupted chest compressions and providing adequate ventilation without breaking the rhythm. After about eight minutes (four two-minute cycles), you should reassess airway management and keep the compression pattern consistent. If you’ve been relying on passive insufflation for ventilation, switch to bag-valve-mask ventilation to provide reliable breaths. If you’ve been ventilating with a bag-valve-mask from the start, continue doing so. In any case, maintain two-minute rounds of uninterrupted chest compressions, with rhythm checks and possible defibrillation performed as indicated at the end of each cycle.
