title: Vaporizer position.
abstract: The vaporizers that are positioned outside of the circle have known constant output concentrations and are not affected by positive pressure ventilation. The vaporizers that are positioned inside the circle system have unknown, variable output concentrations and are markedly affected by positive pressure ventilation. Either type can be safely used if its operating characteristics are understood.
