The pdm and battery involved were not available for ge healthcare engineering evaluation.Investigation into the event was based on the limited information and photos provided by the customer.The customer clarified that the pdm and internal battery did not explode, catch fire nor create any smoke.This is consistent with the photos of the pdm case which showed a melting and slight discoloration of the plastic housing.The investigation concluded the pdm likely overheated due to a shorting of the battery terminals due to fluid ingress.The source of the heat, as indicated by the biomedical technician, was likely the pdm battery which shorted out due to fluid entering the pdm.Conductive cleaning solutions can short out the battery terminals thus causing the battery to overheat.
