Some electrode pads used with the hs1/onsite/home AED have been observed to experience gel separation from the foam/tin backing when peeled from the yellow plastic liner. The gel may fold onto itself, resulting in reduced surface area of gel on the pad. A pad in this condition could cause the hs1/onsite/home AED to deliver less effective or ineffective therapy to the patient due to the reduced surface contact area with the skin.
