Final answer:
The component that directly affects chest compression fraction in high-quality CPR is Interruptions. Minimizing interruptions is essential to maximize the effectiveness of chest compressions and ensure continuous blood flow during CPR.
Step-by-step explanation:
The component of high-quality CPR that directly affects chest compression fraction is B. Interruptions. Chest compression fraction refers to the percentage of time during a cardiac arrest in which chest compressions are being performed, and it is critical to minimize interruptions to maintain high quality CPR. The goal is to achieve a chest compression fraction as close to 100% as possible. Interruptions in chest compressions can significantly reduce the likelihood of successful resuscitation, as they can diminish blood flow to vital organs like the brain.
Proper CPR technique involves applying pressure to the sternum between the T4 and T9 vertebrae, compressing the chest at least 5 cm deep and at a rate of 100 compressions per minute. This rate can be equated to the beat of the song 'Staying Alive' by the Bee Gees for easier memory recall. Ensuring proper hand positioning and depth of compressions, at the correct rate, with complete chest recoil and minimal interruptions is key to the effectiveness of CPR.
However, to avoid injuries like broken ribs or damage to internal organs, proper training and recertification in CPR techniques is essential for medical personnel and the public. This life-saving procedure must be performed correctly to be beneficial.
