The customer received a report of an unconscious patient and attempted to resuscitate the patient using the autopulse platform (sn (b)(6).En route, the customer was informed that bystanders had initiated telephone-based cpr.Upon the arrival of the emergency services, the crew found the patient lying in the garden, having been resuscitated for about 7 minutes.The crew took over the resuscitation efforts, diagnosed ventricular fibrillation, and applied the patches.The crew immediately placed the autopulse platform on the stretcher and resuscitated the patient.The initial positioning on the platform was incorrect, as the patient's arms were also strapped in, but the autopulse did not display any error messages and turned off.After correcting the patient's position, the crew turned the autopulse back on and attempted to continue the resuscitation.This time, the device compressed the patient's chest 5-6 times and then turned off completely, without displaying any error messages.This was repeated approximately 5-6 times.Therefore, the crew switched to manual cpr.No consequences or impacts on the patient.Upon later inspecting the device after the call, the customer confirmed that the battery was fully charged and correctly inserted and locked in place, ruling out these potential sources of error.The autopulse platform was then taken out of service.
