Abstract
The ability of enflurane and halothane to absorb IR energy to visualize their vapors; IR radiation was emitted by a heated screen and the absorption was studied with an IR camera. Even small concentrations of enflurane (0.2 vol%) and halothane (0.5 vol%) were detected when released into the operating room atmosphere. Enflurane and N2O were dispersed in a similar way when they leaked from the face mask. When anesthetic pollution was monitored in the operating room, measurements of the concentration of N2O were sufficient for routine purposes. The IR method added a new dimension to the study of occupational exposure to otherwise invisible gases.This publication has 2 references indexed in Scilit:
