Inhaled Nitric Oxide in Severe Obesity

概要

The goal of this clinical trial is to learn about the effects of inhaled nitric oxide on oxygenation and lung perfusion in participants with severe obesity who have acute hypoxemic respiratory failure and are on mechanical ventilation The main questions it aims to answer are: 1. In acute hypoxemic respiratory failure, what are the effects of inhaled nitric oxide on oxygenation in participants with severe obesity compared to participants with normal body weight. 2. In acute hypoxemic respiratory failure, what are the effects of inhaled nitric oxide on lung perfusion and heart function in participants with severe obesity compared to participants with normal body weight. 3. In acute hypoxemic respiratory failure, does severe obesity impact nitric oxide signaling pathways? Participants with acute hypoxemic respiratory failure will be exposed to inhaled nitric oxide (20 ppm) while being clinically monitored.
