Methemoglobin Concentration in High Dose Inhaled Nitric Oxide (NCT05612074)

Kinetics of Methemoglobin Concentration in Healthy Subjects Exposed to High Dose Inhaled Nitric Oxide

๐Ÿ”ต Active, Not Recruiting Early Phase1 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Massachusetts General Hospital

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
