1. A sensor comprising:
- a solid indicator layer adapted to provide feedback related to a presence of carbon dioxide in a non-gaseous patient sample; and
a selective barrier disposed on a sample-contacting side of the indicator, wherein the selective barrier is permeable to carbon dioxide and substantially impermeable to water.

Abstract
A sensor for carbon dioxide detection may be adapted to have reduced water permeability. A sensor is provided that is appropriate for use in an aqueous medium. The sensor has a barrier with reduced water permeability, but that is permeable to carbon dioxide, that separates the sensor components from the aqueous medium.
