What has been your stepwise approach to oxygenation, including when to consider the use of inhaled nitric oxide or epoprostenol, in refractory hypoxemia due to cardiogenic pulmonary edema in patients who are otherwise not ECMO candidates?

Stepwise Approach to Oxygenation in Refractory Hypoxemia Due to Cardiogenic Pulmonary Edema:

1. Initial Stabilization and Oxygen Therapy:

   • Start with supplemental oxygen to maintain SpOâ‚‚ > 90%.
   • Use noninvasive ventilation (NIV), such as CPAP or BiPAP, to provide positive end-expiratory pressure (PEE...
