The manufacturer previously reported that an everflo oxygen concentrator alleged had sparks and flames coming from the power cord during use.There was no report of patient harm or injury.The device was returned to the manufacturer's service center for evaluation.The customer's complaint was confirmed.The device has evidence of thermal damage to the power cord.The power cord was observed to have damage consistent with the application of excessive force by the end user.It appears the device was placed too close to a hard surface.This caused the power cord to bend, creating weakness in the power cord.Product labeling for the everflo oxygen concentrator states, "keep the device at least 15-30cm away from walls, furniture, and especially curtains that could impede adequate airflow to the device.Do not place the concentrator in a small closed space (suchas a closet)." "do not use the oxygen concentrator if either the plug or power cord is damaged.".
