Excretion of nitrous oxide in anesthetized man

Abstract

The elimination of N₂O was studied in anesthetized man in order to define the excretion process. The end-tidal concentrations of N₂O were determined for approximately 30 min during washout produced by breathing air at rates of alveolar ventilation producing end-tidal CO₂ tensions of approximately 40 mm Hg. The average excretion curve was resolved into three exponentials and the constants determined. Submitted on February 6, 1961
