It was reported that the patient's ventilator was connected to an external marine battery with a cable.When the caregiver was disconnecting the cable from the ventilator pigtail, sparks and a three inch flame came from the ventilator at the strain relief connection to the ventilator.The ventilator continued to ventilate, however, the patient's mother powered the ventilator off and began to manually ventilate the patient.The patient was switched to another ventilator with no patient harm reported.Prior to this incident, fuses on the batteries continued to blow during ventilation and the batteries had been switched out three times to address this issue.

The manufacturer was able to verify that the ventilator's pigtail had burned into two pieces near the strain relief.After a test pigtail was installed, the ventilator passed an extended test run using the customer¿s ventilator settings.During the ltv final test, the ventilator had a non-conformance with the peep pilot pressure test.This slight non-conformance would not result in a failure to ventilate properly.Internal inspection did not reveal any anomalies with the ventilator.The customer did not provide the external battery for further testing.The pigtail was replaced to correct the reported problem.
