Intervention
Circuit change or de-airing with backflush technique
Limitations
Four patients, one centre, one console; abstract only read; backflush technique not described in abstract.
Main result
Source located in all 4; venous side in 3; centrifugal pump airlock with flow cessation in 2. All 4 weaned from ECMO; 3 discharged alive. Authors: systemic gas embolism avoidable with effective management; backflush safe and effective for airlock in Cardiohelp.
Population
116 ECMO patients on Cardiohelp HLS, single centre, October 2009 to July 2020; 4 with circuit gas bubbles or systemic gas embolism.
