The AutoPulse is a brand of mechanical chest compression device designed to perform CPR automatically without the need for continuous manual effort from a rescuer. It applies a band across the chest that compresses the sternum rhythmically at the correct rate and depth, delivering consistent compressions that are difficult to sustain with manual CPR during a prolonged resuscitation.
Mechanical CPR devices provide several advantages over manual compressions in specific situations. They deliver perfectly consistent compressions without fatigue, allowing CPR to continue uninterrupted during patient transport (from the scene to hospital), during procedures difficult to perform alongside manual CPR (such as coronary angiography and PCI), and when insufficient trained rescuers are available to rotate compressions. They are particularly useful in prolonged refractory cardiac arrests and in extracorporeal CPR (eCPR) scenarios.
Clinical trial evidence for mechanical CPR devices has not consistently shown improved neurological survival compared to high-quality manual CPR, and current guidelines do not recommend them as a routine replacement for manual compressions. They are best used in specific situations where sustaining manual CPR is impractical: in the catheterisation laboratory, on a moving vehicle, or during prolonged arrest awaiting specialist intervention.
Families who see a mechanical chest compression device in use at a resuscitation should be reassured that it is performing the same function as manual chest compressions. Its use is driven by the practical demands of the resuscitation, not by the patient’s prognosis.
