What is "in two-person cpr?

In two-person CPR, two rescuers work together to provide more effective and sustained support to a person experiencing cardiac arrest. The primary roles are often designated as "Rescuer 1" and "Rescuer 2."

Rescuer 1:

• Typically handles chest compressions. They ensure high-quality compressions are delivered at the correct rate (100-120 compressions per minute) and depth (at least 2 inches for adults). It is important to allow for full chest recoil between compressions. Minimizing interruptions to compressions is crucial.

Rescuer 2:

• Manages the airway and provides rescue breaths. This involves opening the airway using the head-tilt/chin-lift maneuver (unless a spinal injury is suspected) and delivering breaths, ensuring visible chest rise. With advanced airways (like an endotracheal tube), breaths are often given asynchronously without pausing compressions.
• Coordinates with Rescuer 1 to minimize interruptions.

Coordination and Switching:

• A key advantage of two-person CPR is the ability to switch roles approximately every two minutes (or about every 5 cycles of 30 compressions and 2 breaths) to prevent rescuer fatigue and maintain the quality of compressions.
• The switch should be done quickly and efficiently to minimize interruptions. Rescuers should communicate clearly during the switch. Rescuer 1 counts down until the change to let the rescuer 2 know they will start to give compressions soon.
• Two-person CPR allows for faster AED integration by having one person ready and prepared when it becomes available.

Ratio:

• When there's no advanced airway: 30 compressions to 2 breaths. This is the same ratio as one-person CPR in most cases.
• When there is an advanced airway in place: Deliver continuous chest compressions at a rate of 100-120 per minute, and give one breath every 6 seconds (10 breaths per minute).

The goal of two-person CPR is to optimize circulation and oxygenation until more advanced medical care arrives.
