Final answer:

The chest compression fraction in high-quality CPR is profoundly influenced by the correct hand positioning on the sternum and maintaining the correct compression depth and rate. Ensuring hands are positioned between the T4 and T9 and applying compressions at the recommended depth and rate are critical to circulating blood and preventing brain damage in the absence of spontaneous heartbeat.

Step-by-step explanation:

The component of high-quality CPR (cardiopulmonary resuscitation) that directly affects chest compression fraction is the proper positioning of the hands on the sternum and the depth and rate of chest compressions. Positioned between the lines of T4 and T9 on the sternum, the hands apply pressure to compress the chest at least 5 cm deep and at a rate of 100 compressions per minute.

This rate is essential to maintain proper circulation, particularly to the brain, to prevent neuron damage or death due to lack of blood flow. High-quality CPR underscores the importance of robust compressions over artificial respiration and should be executed until the patient shows signs of recovery or is otherwise declared by a professional. Proper training is crucial, as incorrect technique may result in severe injuries to the patient, therefore certification and recertification in CPR are imperative for medical personnel and the public.
