A dhr review was completed and there were no noted nonconformances within the dhr.Product testing met all specifications and there were no issues identified with the raw materials used.The sample was returned for evaluation.Apex pad did not show any signs of heat damage however the sternum pad showed char marks.It was noted that there was excessive hair adhered to the sternum pad.Further investigation did confirm that the patient was not shaved prior to use of the pads.This could lead to poor adherence to the skin and cause an air gap to be present.
