During a multi-provider CPR session, what should the compression-to-ventilation ratio be when switching roles?

In a multi-provider CPR scenario, the correct compression-to-ventilation ratio when switching roles is 15:2. This ratio is specifically designed to optimize the effectiveness of CPR for adult patients. It allows for a higher frequency of compressions while still providing adequate ventilations.

The guideline of 15 compressions followed by 2 breaths is essential in a team environment because it helps maintain blood circulation to the heart and brain, which is critical during cardiac arrest. The ratio emphasizes the importance of high-quality chest compressions, which should remain consistent and are ideally delivered at a rate of 100-120 compressions per minute. After a set of 15 compressions, the rescue provider can give 2 breaths, facilitating oxygenation.

Using this ratio helps teams work efficiently and prevents fatigue among rescuers by allowing them to rotate roles more frequently, ensuring that compressions are sustained without significant breaks. This approach assures that both compressions and ventilations are given substantial attention, which is vital for the patient's survival and recovery.
