Previously healthy patient admitted to outside hospital three months ago with multilobar pneumonia.Pt placed on v-v ecmo approximately 4 days after admission to outside facility.Transferred to this facility on ecmo approximately one month later for lung transplant evaluation and has remained on ecmo.Approximately 2 months after transfer to this facility, 2 rns performing routine q 12 hr flush and zeroing of the ecmo circuit pressure lines.Immediately after zeroing line on venous side of ecmo circuit & releasing pigtail stopcock, ecmo rns noted air on venous and arterial side of oxygenator of the ecmo circuit.Rn immediately clamped the lines.Code team summoned.Pt bagged and prolonged resuscitation including chest compressions and arrest meds occurred while pt was recannulated and converted to veno arterial ecmo.Pt remained critical and the next afternoon, after lengthy discussion with mds, parent requested that we withdraw treatment.Patient expired while surrounded by family.How air got into the circuit is not known at this time.The tubing remained visually intact & did not "fall apart"; however, it is possible that the stopcock and connectors became loose and allowed air to be drawn into the line.There have been no previous issues with the tubing at this facility.The ecmo machine did not alarm: air was detected by the two ecmo rn's before the air reached the ecmo circuit.Both ecmo rn's had received training/education to perform the line flush and are experienced in this procedure.Preliminary cause of death is ards.Autopsy being performed.
