Extracorporeal Membrane Oxygenation, or ECMO, is a specialty within our Critical Care department. The ECMO team caring for your child is made up of a neonatologist or an intensivist, surgeon, ECMO primer, ECMO specialist, ICU nurses and respiratory therapists. This program was the first pediatric and neonatal ECMO program in Arizona, and involves recognized ECMO experts from across the state.
