1. Apparatus for delivering pressurized, humidified breathable gas to a patient having a sleep-related disorder, the apparatus comprising:

  • a CPAP unit comprising a blower configured to generate a flow of pressurized breathable gas;

    a liquid storage container configured to hold a body of liquid, the liquid storage container comprising a gas feed opening, a gas discharge opening and a humidifying region above a metallic heat conducting material, the humidifying region being a region inside the liquid storage container in which the pressurized breathable gas generated by the CPAP unit passes over and absorbs water vapor generated from the body of liquid; and

    a support housing integrated directly into the CPAP unit and having a receiving space configured to removably receive the liquid storage container, the support housing comprising;

    a gas feed flow path in fluid communication with an outlet of the CPAP unit and having an ending portion that opens up to the receiving space; and

    a gas discharge flow path configured to be fluidly connected to an air delivery tube and having a beginning portion that opens up to the receiving space, the gas feed flow path and the gas discharge flow path being separated from each other,wherein the liquid storage container is structured such that when the liquid storage container is received by the support housing, the gas feed opening aligns with and engages with the ending portion of the gas feed flow path and the gas discharge opening aligns with and engages with the beginning portion of the gas discharge flow path so that the liquid storage container fluidly connects the gas feed flow path and the gas discharge flow path.
