At minimum how long should an EMT perform CPR on scene?

• A. 8 minutes
• B. 2 minutes
• C. 4 minutes
• D. 6 minutes

Answer: (A)

Maintaining blood flow to vital organs relies on continuing high‑quality CPR for as long as the patient remains in cardiac arrest and until definitive care is ready. The minimum on‑scene CPR duration is eight minutes because it allows several full cycles of chest compressions, time for rhythm checks and potential defibrillation, airway management if needed, and coordination of transport to definitive care, all while keeping perfusion going to the brain and heart. If return of spontaneous circulation occurs at any point, CPR is stopped. While performing CPR, keep the rate about 100–120 compressions per minute, depth around 2 inches (5 cm) for adults, with minimal interruptions and a quick switch of compressors every two minutes.
