How does the compression-to-ventilation ratio differ between single-provider CPR and multiple-provider CPR for adults?

The compression-to-ventilation ratio remains the same for both single-provider CPR and multiple-provider CPR for adults, which is 30 compressions followed by 2 ventilations. This standard ratio is established to maximize the effectiveness of CPR by ensuring that the victim receives adequate oxygenation through ventilations while maintaining sufficient blood circulation through chest compressions, regardless of the number of providers assisting in the effort.

In single-provider CPR, the provider is responsible for both providing compressions and delivering ventilations, while in multiple-provider CPR, roles can be shared, but the same ratio is maintained to ensure consistency in the protocol. Therefore, it is essential for both scenarios that the ratio stays uniform to ensure effective resuscitation efforts.
