Event or Problem Description
During a reported rescue attempt, the customer stated that the aed failed to power on and the aed's asi was blank.As a result, the aed was not used during the event.Manual cpr was performed by responders until paramedics arrived on scene.It was reported the patient survived to hospital.
Additional Manufacturer Narrative
Analysis of the log files from the aed showed that the aed was placed into service without the pads connected to the aed.The ddu series aeds are designed to be stored with the pads connector already installed.This simplifies the procedure for deploying and operating the device in an emergency.During the aed's automated self-test, the aed identified that the pads were not connected and attempted to alert the user by flashing its red asi and chirping.The aed continued to chirp and flash without any evidence in the log of any human interaction to address the aeds condition until the battery pack became completely depleted.The cause of the aed not powering on was related to a failure of the customer to set-up the aed and maintain the battery pack.
