ABSTRACT:
Apparatus for delivering conditioned gas to be breathed by a living being includes a humidifier for conditioning gas provided from a source, inhalation conduit means for conducting an inhalant flow of conditioned gas from the humidifier to the living being, and exhalation conduit means for conducting away gas exhaled by the living being, the inhalation conduit means having a first and a second conduit each extending between and communicating with the humidifier and a delivery point near the living being, gas propulsion apparatus for propelling a carrier flow of gas within the first conduit from the conditioner to the delivery point and within the second conduit from the delivery point to the humidifier, the first and second conduits and the gas propulsion apparatus being adapted to maintain a circulating flow of conditioned gas that includes the inhalant flow and the carrier flow through a loop defined by the first and second conduits, the delivery point, and the humidifier, the demand of the patient being taken from the circulating flow at the delivery point, whereby the gas is conditioned to substantially the same extent at the delivery point as at the humidifier.
