Study Summary

The goal of this clinical trial is to learn about the kinetic of methemoglobin in healthy subjects breathing high dose inhaled nitric oxide. The main questions it aims to answer are: * What are the kinetics of methemoglobin formation at a maximum of 300 parts per million of nitric oxide and oxygen * What are the kinetics of methemoglobin reduction after nitric oxide discontinuation Participants will be exposed to intermittent high dose inhaled nitric oxide at a maximum of 300 parts per million while being continuously monitored.
