Final answer:
In CPR, interruptions to chest compressions to check for a pulse should be limited to less than 10 seconds to ensure continuous blood flow to vital organs.
Step-by-step explanation:
When performing cardiopulmonary resuscitation (CPR), current guidelines emphasize the importance of minimizing interruptions to chest compressions. While checking for a pulse is necessary, it is recommended to limit these interruptions to less than 10 seconds. The objective is to maintain blood circulation, especially to vital organs like the brain. During CPR, chest compressions should be at least 5 cm deep and at a rate of approximately 100 compressions per minute, which aligns with the beat of the song "Staying Alive" by the Bee Gees.
