First seen Jan 11, 2026 · Last updated Apr 28, 2026 · Updated 18 times
Summary
This study looks at how the body forms and clears methemoglobin when healthy people breathe high doses of nitric oxide gas. Ten volunteers aged 18–64 will inhale up to 300 parts per million of nitric oxide in short bursts while being closely monitored. The goal is to understand the safety and body chemistry of this gas, not to treat any disease.
