A delivery tube assembly for delivering a breathing gas to a patient, the delivery tube includes a first lumen having an upstream portion and a downstream portion. The lumen is configured to deliver the breathing gas from the upstream portion to the downstream portion. A second lumen is configured to flow an insulating gas around the first lumen. A method of insulating a breathing gas with an insulating gas and discharging the insulating gas to atmosphere is also disclosed.


1. A delivery tube assembly for delivering a breathing gas to a patient, the delivery tube comprising: a first lumen having an upstream portion positionaly away from the patient and a downstream portion towards the patient, the lumen configured to deliver the breathing gas from the upstream portion to the downstream portion; a second lumen having an upstream portion and a downstream portion and at least partially surrounding the first lumen and configured to flow an insulating gas in the same direction as the breathing gas around the first lumen; and a d...
