1. A medical device comprising:

  • a conduit adapted to transfer a gas to or from a patient; and

    a plurality of sensing components associated with a respective plurality of locations on the conduit, wherein the plurality of sensing components is adapted to provide a signal related to a carbon dioxide gas in the conduit at the respective plurality of locations, wherein at least one of the plurality of sensing components comprises a borosilicate substrate having an acrylic binder incorporated within the borosilicate substrate, and a carbon dioxide-responsive indicator solution disposed on the borosilicate substrate wherein the acrylic binder increases a hydrophobicity of the borosilicate substrate relative to borosilicate alone.
