1. A universal respiratory detector for detecting a respiratory gas and displaying a respiratory status based on the gas, the respiratory detector comprising:
a first side and a second side opposite the first side;
a cover layer on the first side;
a transparent or translucent backing on the second side;
a respiratory sensor layer comprising a visual indicator, wherein the respiratory sensor layer is between the cover layer and the transparent or translucent backing, the visual indicator configured to reversibly change color when a respiratory gas parameter changes and to display the color change, wherein the color change is visible from both the first side and the second side;
a biocompatible adhesive layer on top of the cover layer, wherein the adhesive layer is configured for attaching the detector to an oxygen delivery device or a face of a user,
wherein the universal respiratory detector is a sticker, and further wherein the detector is configured to conform to a curved or variable surface contour of the oxygen delivery device or the face of the user and configured to flex and move together with movement of the oxygen delivery device or the face of the user.
