Final answer:
Every 2 minutes or after about 150 compressions (5 cycles of 30 compressions), it is recommended to switch CPR providers to maintain high-quality chest compressions.
Step-by-step explanation:
The question is every 2 minutes or every 5 cycles of 30 compressions each. This practice is recommended to ensure the effectiveness of chest compressions during CPR (cardiopulmonary resuscitation).
CPR is a critical emergency procedure used to manually pump blood through the heart when it stops beating. The goal is to maintain blood flow, especially to the brain, to prevent irreversible damage. During CPR, a responder delivers chest compressions at a depth of at least 5 cm and at a rate of 100 compressions per minute. It's crucial to maintain the quality of chest compressions, and fatigue can lead to less effective compressions. To counter this, it is recommended that the person performing CPR switch with another provider every 2 minutes or after approximately 5 cycles of 30 compressions each. Taking these breaks helps to maintain the intensity and depth of compressions, which is vital for increasing the patient's chances of survival until advanced medical help arrives or spontaneous circulation resumes.
