When should compressions begin after recognizing cardiac arrest?

• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 20 seconds

Answer: (B)

Compressions should begin within 10 seconds after recognizing cardiac arrest. This guideline emphasizes the importance of immediate action in response to cardiac arrest, as prompt compressions can significantly increase a person's chance of survival by maintaining blood flow to vital organs until advanced care is available. The urgency in starting compressions is grounded in the recognition that every moment counts during cardiac arrest. The brain and heart are highly sensitive to the lack of oxygenated blood, and even a delay of more than 10 seconds can begin to compromise the chances of a successful resuscitation. This standard is part of the overall emphasis within BLS protocols on minimizing delays in starting high-quality chest compressions, thus highlighting the critical role that timely intervention plays in emergency situations.
