A ge healthcare service representative retrieved the device logs but did not perform any tests per customer request.Ge healthcare product engineering performed an investigation of this event.The ventilator logs show that the ventilator display lost power, then regained power while the ventilator continued to ventilate the patient.When the ventilator display regained power, all the subsystems were already running, so the ventilator display could not complete the bootup sequence and communicate with the subsystems.This caused the ventilator to display the ventilator failure쳌 message.Per the ventilator user manual, when this internal error occurs, it states, the ventilator will continue to ventilate the patient with the current settings and show this [ventilator failure] message on the display".However, it may be difficult to visually see if the patient is still being ventilated from chest movement or by listening to sounds from the heart, lungs, or other organs.Therefore, the ventilator user manual also states that, access to an appropriate alternative means of ventilation at all times is required to prevent patient injury or death in the event of ventilator failure.쳌 since the ventilator display is unavailable to make changes to ventilation, it is up to the clinician to decide if the patient should be manually ventilated while attempting to reboot the ventilator, manually ventilate while securing alternate ventilation, or to transfer the patient to an alternate source of ventilation.In this case, the patient was removed from the ventilator and manually ventilated, and suffered a cardiac arrest due to the patient âs critical condition.
