1. A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system, the gas delivery conduit comprising:
a first connector adapted for connecting to both a tubular outlet of the respiratory gases delivery system and a receptacle wall of the respiratory gases delivery system that protrudes from an exterior wall of the respiratory gases delivery system and defines a space including system electrical contacts of the respiratory gases delivery system, wherein the first connector comprises both a gas inlet having a tubular wall portion configured to be fluidly connected to the tubular outlet of the respiratory gases delivery system to receive a supply of respiratory gas and an offset connector flange that extends to a distal tip of the first connector at a position exterior to the tubular wall portion to slidingly mate with the receptacle wall of the respiratory gases delivery system that protrudes from the exterior wall of the respiratory gases delivery system, wherein the first connector further comprises conduit electrical contacts spaced apart and laterally offset from the tubular wall portion of gas inlet so as to mate with the system electrical contacts of the respiratory gases delivery system when the offset connector flange slidingly mates with the receptacle wall of the respiratory gases delivery system that protrudes from the exterior wall of the respiratory gases delivery system;
a second connector adapted for connecting to a fitting of a patient interface;
tubing fluidly connecting the first connector to the second connector;
a heating element configured to warm the supply of respiratory gas within the tubing, wherein the heating element is configured to be powered and controlled via the electrical connection between the conduit electrical contacts and the system electrical contacts; and
a sensor configured to measure a condition of the supply of respiratory gas, wherein the sensor is configured to supply a signal indicating the condition to the respiratory gases delivery system via the conduit electrical contacts.
