NCT ID NCT07690358
First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time
Summary
This study measures how long nitrous oxide can be detected in blood, exhaled air, and urine after three types of exposure: inhaling cartridges in a car, eating whipped cream, or working as a midwife in a delivery room. Researchers will track levels for up to two hours. The goal is to understand how different exposures affect detection times, which could inform safety and legal guidelines.
