Mechanical devices for chest compression: to use or not to use?

Area of Science:

• Cardiology
• Emergency Medicine
• Resuscitation Science

Background:

• High-quality manual chest compressions are difficult to achieve in practice.
• Mechanical chest compression devices offer consistent compression delivery.
• Recent large trials provide new insights into device efficacy.

Purpose of the Study:

• To review the role and efficacy of mechanical chest compression devices in cardiac arrest.
• To analyze findings from recent large prehospital trials.
• To assess the current evidence for device use in different settings.

Main Methods:

• Review of large prehospital randomized controlled trials: CIRC, LINC, and PARMEDIC.
• Analysis of observational studies on device use in specific circumstances.
• Evaluation of data regarding in-hospital cardiac arrest scenarios.

Main Results:

• Large prehospital trials (CIRC, LINC, PARMEDIC) found no survival benefit of mechanical devices over manual CPR.
• Limited data exist on routine mechanical device use during in-hospital cardiac arrest.
• Observational studies suggest benefits in specific situations, such as bridging to advanced therapies like ECMO.

Conclusions:

• Mechanical cardiopulmonary resuscitation (CPR) shows similar survival rates to manual CPR in out-of-hospital cardiac arrest.
• Evidence is insufficient to support or refute routine mechanical CPR device use in-hospital.
• Mechanical CPR is feasible when manual CPR is challenging and can serve as a bridge to advanced therapies.
