1. A method of forming a custom fitted mask configured for coupling to an external gas supply system, comprising:

  • applying a first sheet of deformable material against a user'"'"'s face surrounding the user'"'"'s nostrils while the first sheet is in a deformable state;

    deforming the first sheet against the user'"'"'s face to cause the first sheet to conform substantially optimally to the user'"'"'s unique facial features;

    configuring a second sheet of deformable material around a fitting adapted for coupling to the external gas supply system;

    applying a contact portion of the second sheet against a contact portion of the first sheet while the second sheet is in a deformable state such that the fitting is positioned between the first and second sheets;

    deforming the contact portion of the second sheet against the contact portion of the first sheet with the fitting positioned between the first and second sheets to cause the contact portion of the second sheet to conform substantially optimally to the contact portion of the first sheet;

    allowing the contact portion of the second sheet to bond to the contact portion of the first sheet; and

    allowing the second sheet to transition from the deformable state to a non-deformable state to form the custom fitted mask configured for coupling to the external gas supply system.
