Why is it important to allow full chest recoil during compressions?

• A. To keep the airway open
• B. To decrease chest discomfort
• C. To allow the heart to refill with blood
• D. To prevent fatigue in the rescuer

Answer: (C)

Allowing full chest recoil during compressions is crucial primarily because it facilitates the heart's ability to refill with blood. When chest compressions are performed, the heart is mechanically compressed, which helps to pump blood to vital organs. However, if the chest does not fully recoil after each compression, it can impede the return of blood to the heart, thereby reducing the volume of blood available for the next compression. This can lead to ineffective perfusion and ultimately decrease the chances of maintaining adequate circulation during a cardiac arrest scenario. The recoil phase creates a negative pressure in the chest cavity, allowing blood to flow back into the heart from the veins, which is essential for adequate blood flow during resuscitation efforts. Therefore, ensuring full chest recoil is vital for maximizing the effectiveness of CPR and improving the likelihood of restoring a spontaneous heartbeat.
