ABSTRACT:
A method of controlling the delivery-point temperature and vapor level of a gas which is conveyed through a delivery line from a heater/humidifier to a delivery point. The method is particularly applicable to apparatus for use in the medical field and it involves heating and humidifying the gas to a temperature T.sub.1 and to a vapor level W.sub.1 of less than 100% saturation, and controlling the temperature of the gas in the delivery line to provide for a lower temperature T.sub.2 which corresponds to a selected higher vapor level W.sub.2 at the delivery point.
