Final answer:
The element not part of adult high-performance CPR is maintaining a 2:30 ratio of ventilations to compressions. High-performance CPR emphasizes at least 100 compressions per minute and a depth of at least 5 cm.
Step-by-step explanation:
One element that is NOT part of adult high-performance CPR is maintaining a 2:30 ratio of ventilations to compressions. High-performance CPR for adults emphasizes a compression rate of at least 100 per minute and a compression depth of at least 5 cm. When performing CPR, it is also crucial to place the heel of one hand on the center of the victim's chest, specifically between the lines at T4 and T9 on the sternum, to effectively squeeze the blood out of the heart and into the circulation.
A depth of more than 1 inch (2.54 cm) is typically recommended, contrary to the incorrect option stating compressions should be no more than 1 inch in depth. Proper training in CPR is advised to avoid severe damage to the patient, such as rib fractures or liver injuries caused by incorrect hand placement.
