Early Rehabilitation in Patients on Extracorporeal Membrane Oxygenation

The intervention involves a progression of rehabilitation exercises with the objective of rehabilitating the patient at the highest level of exercise possible for the patient for the longest period of time that can be tolerated (up to 60 mins) at each session. The intervention will be administered 5 days per week (weekdays) while the patient remains in ICU, censored at 28 days after randomisation.
