Effect of iNO in Patients With Submassive and Massive PE

Summary

A single center study to evaluate the effect of inhaled nitric oxide (iNO) on pulmonary dynamics in patients presenting with imaging confirmed intermediate/submassive or massive pulmonary embolism (PE). The target enrollment is 20 subjects at Ronald Reagan UCLA Medical Center. PE patients undergoing catheter-based intervention will be administered iNO during their intervention and pulmonary hemodynamic measurement will be measured before, during, and after iNO administration (Invasive Cohort). Patients who are not undergoing catheter-based intervention will also be administered iNO and will have pulmonary hemodynamics, blood pressure, and heart rate measured non-invasively (Non-Invasive Cohort).
