Uploaded and shared in Youtube by: USFoodandDrugAdmin — Physio-Control has alerted users of LIFEPAK 20 and LIFEPAK 20e defibrillators about possible failures in AC or DC power that could delay or prevent these devices from delivering therapy. If a failure occurs while the device is being used in the AC or line-power mode, the unit should automatically switch to the DC, or battery mode. But after the battery is depleted, the AC failure will prevent the battery from recharging and all power will be lost. All power could also be lost if a failure occurs in the DC, or battery mode and the user cannot plug the unit into an AC source. The company says that it will update the power supplies on the affected devices. In the meantime, users should keep the units in service if they are functioning normally. It is important to inspect and test the devices every day according to the company's operating instructions, because that can help identify potential power failures. If possible, the units should be kept connected to an AC source with the batteries charged. For more information, contact Physio-Control Technical Support at 1-800-442-1142.
