Final answer:
Interruptions in chest compressions during CPR should be limited to less than 10 seconds. This allows for sufficient blood circulation, reducing the risk of brain damage due to a lack of oxygen.
Step-by-step explanation:
The correct answer to the question regarding interruptions in chest compressions during CPR is A. Less than 10 seconds. Chest compressions are a critical part of cardiopulmonary resuscitation, and minimizing interruptions is essential for maintaining blood flow to the brain and other vital organs. During CPR, the chest should be compressed at least 5 cm deep at a rate of approximately 100 compressions per minute.
Any interruption should be as brief as possible. The ideal is to limit pauses to less than 10 seconds, which is especially important during the crucial moments when a defibrillator is being prepared or when checking for signs of life. Quick resumption of compressions is vital after these necessary interruptions. Proper training in CPR technique is critical, as improper hand placement or technique can lead to severe injuries like a broken sternum or ribs.
