Two rescuers begin high-quality CPR while the third rescuer leaves to get the AED. What action supports 2-rescuer CPR?
The Correct Answer and Explanation is :
In two-rescuer CPR, one rescuer performs chest compressions while the other provides ventilations. To maintain high-quality CPR and prevent rescuer fatigue, it’s essential to alternate roles every two minutes. This practice ensures that both rescuers remain effective throughout the resuscitation effort.
Explanation:
High-quality CPR involves delivering chest compressions at a rate of 100 to 120 per minute, with a depth of at least 2 inches (5 cm) for adults, allowing full recoil between compressions. Providing ventilations at a ratio of 30:2 (compressions to breaths) is also recommended. Performing these tasks continuously can lead to fatigue, which may reduce the effectiveness of CPR.
By alternating roles every two minutes, rescuers can rest briefly, allowing them to continue performing CPR at optimal quality. This strategy helps maintain the necessary compression rate and depth, as well as the appropriate ventilation rate, thereby increasing the likelihood of a successful resuscitation.
Additionally, alternating roles every two minutes aligns with the American Heart Association’s guidelines, which emphasize the importance of minimizing interruptions in chest compressions and ensuring that rescuers are well-rested to perform high-quality CPR.
In summary, to support two-rescuer CPR, it’s crucial to alternate the roles of chest compressions and ventilations every two minutes. This practice helps prevent rescuer fatigue, maintains the quality of CPR, and improves the chances of a positive outcome for the individual in need.
