Final answer:
To perform high-quality CPR on a 5-year-old child, the chest should be compressed to a depth of at least 2 inches. Proper hand placement and technique are critical to avoid potential injuries and effectively maintain blood flow to vital organs.
Step-by-step explanation:
When performing CPR (cardiopulmonary resuscitation) on a 5-year-old child in cardiac arrest, you ensure that high-quality CPR is administered by compressing the chest to a depth of at least 2 inches (5 cm). It is crucial to note that the compression must be done with care, as improper technique can cause injury to the child. Proper placement of hands is between the lines at T4 and T9 on the sternum to effectively compress the heart and maintain blood flow, especially to the brain, where irreversible damage can occur within minutes without blood flow.
Current CPR guidelines emphasize high-quality chest compressions over artificial respiration, aiming for a compression rate of 100 compressions per minute. Proper training and certification for CPR are highly advised for medical personnel and the general public to avoid potential injuries such as broken ribs or damage to internal organs. By following these guidelines, you can effectively support the circulatory system until professional medical assistance is available or the heart resumes beating.
