Why is allowing complete chest recoil important when performing high-quality CPR?

A. The rate of chest compressions will increase.
B. It will reduce the risk of rib fractures.
C. The heart will adequately refill between compressions.
D. There will be a reduction of rescuer fatigue.

When you are performing CPR on an unresponsive person whom you know is choking, what modification should you incorporate?

A. You should attempt a jaw thrust instead of a head tilt-chin lift.
B. You do not give breaths to an unresponsive choking victim.
C. Each time you open the airway, you look for the obstructing object.

Complete chest recoil during CPR is vital for allowing the heart to refill properly between compressions, enhancing blood flow. For unresponsive choking victims, breaths should not be given, focusing instead on chest compressions. These practices are essential to improve survival chances in emergency situations.

Explanation:

Importance of Complete Chest Recoil in CPR

Allowing complete chest recoil during CPR is crucial for several reasons. The correct answer to the first question is C. The heart will adequately refill between compressions. When the chest fully recoils after each compression, it creates a negative pressure in the thoracic cavity, which helps to draw blood back into the heart. This process is essential for maintaining effective blood circulation and ensuring that the heart has enough volume to pump effectively during the next compression.

If the chest does not fully recoil, the heart may not refill properly, leading to decreased blood flow to vital organs and ultimately reducing the chances of survival. Additionally, while correct compression depth and rate are important, allowing for complete recoil primarily impacts the efficacy of blood flow.

CPR Modifications for Choking Victims

When performing CPR on an unresponsive person whom you know is choking, the correct modification to incorporate is B. You do not give breaths to an unresponsive choking victim. In such cases, the airway is obstructed, and giving breaths can lead to further complications. Instead, focus on delivering chest compressions to try to expel the obstruction.

It is also relevant to mention that after each set of compressions, you should check for the obstructing object; however, the priority remains to remove the obstruction through compressions until the airway is clear.
