What is the alternate method to chest compressions described for CPR when two people are involved?

• A. Interposed Abdominal Compressions
• B. Chest-only CPR
• C. Two-person Chest Compressions
• D. Defibrillation

Answer: (A)

Interposed abdominal compressions are the alternate two-person CPR method. In this approach, one rescuer does chest compressions while the other delivers a rapid abdominal compression between those chest compressions. The idea is to boost circulation by increasing venous return and diastolic pressure, potentially improving perfusion to the heart and brain during CPR. This concept was described for two rescuers, but it isn’t standard in current guidelines due to mixed evidence and potential for injury. The other options don’t describe a two-person variation: chest-only CPR omits ventilations, two-person chest compressions is just the standard two-rescuer version without the abdominal component, and defibrillation is a separate treatment, not a method of performing compressions.
