Carbon dioxide detector having borosilicate substrate
First Claim
1. A carbon dioxide detector comprising:
- a borosilicate substrate having an acrylic binder; and
a carbon dioxide responsive indicator solution disposed on the borosilicate substrate, wherein the indicator solution changes color in less than 1 second in the presence of carbon dioxide above a first level.

Abstract
The present disclosure relates to a carbon dioxide detector having a borosilicate substrate. It may also have a carbon dioxide responsive indicator solution disposed on the borosilicate substrate. The carbon dioxide detector may be part of a carbon dioxide detector system also including an air intake operably connected to the housing to allow air to reach the carbon dioxide detector. The carbon dioxide detector may include a borosilicate substrate and a carbon dioxide responsive indicator solution disposed on the borosilicate substrate. This detector may be part of a further system, such as a resuscitation system. The detector may be made by wetting a borosilicate substrate with a carbon dioxide responsive indicator solution and drying the indicator solution to immobilize it and form a dried carbon dioxide detector. It may be used to detect the concentration of carbon dioxide in an air sample by exposing the detector to the sample.
