All subjects enrolled with be assigned to Arm 1

Enrolled subjects will undergo a Hyperfine MRI exam, which is a portable, low-field MRI, at various timepoints during their clinical course on ECMO

Measuring the occurrence of adverse events and serious adverse events that occurring during the portable MRI procedure. Adverse events and serious adverse events include (change in mean arterial pressure by 20% increase or decreased measured by the meters of mercury as identified by catheter measurement in patient, a decrease in the ECMO flow rate by 20% measured in milliliters per min by the ECMO machine, decrease in the oxygen saturation by 10% measured by pulse oximetry, dislodgement of the ECMO cannula measured by the occurrence of hemorrhage, as identified by PI).

The analyses will examine the amount of time it takes to conduct a Portable MRI with ECMO patients. The examination records the amount of time to prep and move the patient to the portable MRI and back from the portable MRI. Preparation and movement of patient will be measured using a stopwatch identifying the number of minuets passed. The amount of time it takes to conduct the portable MRI with ECMO patients will also be analyzed. The time the MRI takes will be measured using a stopwatch examining the number of minuets passed.

The analysis will examine the number of staff needed to prep and use a portable MRI with patients. Number of staff needed will be record in RedCap via head count.

Analyzing the number of critical therapies conducted during patient prep, during intervention, and post intervention. The study will record in RedCap the number of critical care therapies identified by study coordinator and PI by counting the number of therapies. Critical care therapies include (EEG, mechanical ventilation, continuous renal replacement therapy, continuous IV infusions, temporary pacing wires).
