Is this trial a fit for you?
✓Likely a good fit
Adults 18 years and older with cardiac ICU admission requiring invasive ventilation for more than 12 hours, including those with cardiogenic shock, reduced ejection fraction, or right heart dysfunction.
✕Probably not a fit
Patients with very short expected ventilation duration (<12 hours), severe COPD or ARDS without pulmonary edema, or those on home ventilation or ECMO may not benefit from this comparison.

What this trial studies
This feasibility pilot investigates two ventilation strategies—volume-controlled and pressure-controlled modes—in adults admitted to a cardiac ICU who require invasive mechanical ventilation for more than 12 hours. The study aims to assess feasibility and gather exploratory data on how these modes affect patient-ventilator interaction, sedation needs, and hemodynamics in the setting of cardiogenic disease and varying degrees of heart failure or shock. Participants may belong to predefined subgroups such as cardiogenic shock stages, use of mechanical circulatory support, reduced ejection fraction, right ventricular dysfunction, or pulmonary hypertension. The trial is led by Mayo Clinic and conducted at the Mayo Clinic in Rochester, Minnesota, without listed collaborators. Outcomes will inform whether a larger, definitive comparison is warranted in this high-risk population.
Why it matters
Potential benefit: If feasible and favorable, selecting the optimal ventilation mode could improve hemodynamics and comfort, potentially reducing complications and length of ICU stay.
How similar studies have gone: Prior data on ventilator modes in mixed critical care populations suggest mode choice can impact comfort and favor some hemodynamic profiles, but evidence is limited in cardio-cardiac ICU patients; this remains relatively novel in this specific group.

Neuromuscular electrical stimulation for patients on invasive mechanical ventilation (MOVCARE)
We will test whether adding neuromuscular electrical stimulation to usual physical therapy helps adults on invasive mechanical ventilation regain leg muscle strength faster.
