Which devices can provide continuous chest compressions during long resuscitation efforts?

• A. Manual-only devices.
• B. Mechanical chest compression devices.
• C. Defibrillators.
• D. Oxygen masks.

Answer: (B)

Sustained, high-quality chest compressions over long resuscitation efforts rely on a tool that can deliver consistent depth and rate without fatigue. Mechanical chest compression devices remove the fatigue factor and maintain continuous compressions, even during transport or when rescuers are occupied with other tasks like airway management or medication administration. This helps preserve coronary and cerebral perfusion when the resuscitation is prolonged. Manual compressions, while essential, degrade in quality as rescuers tire, leading to interruptions and shallower compressions. Defibrillators and oxygen masks play crucial roles in resuscitation, but they do not provide continuous chest compressions. So the best option for continuous chest compressions over long efforts is mechanical chest compression devices.
