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, wherein the cover layer covers at least part of a backing;
a respiratory sensor layer comprising the backing and a visual indicator on the 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; and
a biocompatible adhesive on the cover layer and a release liner on top of the biocompatible adhesive,
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 an oxygen delivery device or a face of a user and configured to flex and move together with movement of the oxygen delivery device or the face of the user.
 
15. 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, wherein the cover layer covers at least part of a backing; and
a respiratory sensor layer comprising the backing and a visual indicator on the 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,
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 an oxygen delivery device or a face of a user and configured to flex and move together with movement of the oxygen delivery device or the face of the user,
wherein the universal respiratory detector comprises a maximum thickness of less than 0.1 inches.
 
18. 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, wherein the cover layer covers at least part of a backing; and
a respiratory sensor layer comprising the backing and a visual indicator on the 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,
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 an oxygen delivery device or a face of a user and is configured to flex and move together with movement of the oxygen delivery device or the face of the user,
wherein the universal respiratory detector has a longest dimension of less than 2 inches.
