Abstract
Carbon dioxide indicator for receiving gas containing carbon dioxide and for providing a visible indication of the presence of carbon dioxide in the gas, the indicator includes a connector for removably connecting the indicator to a source of gas containing carbon dioxide and which connector is for communicating at least a portion of such gas to the indicator. The carbon dioxide indicator may be a disk indicator and the connector may be a male luer or a locking male luer. The carbon dioxide indicator may include removable ultraviolet radiation shielding permitting the carbon dioxide indicator to be preassembled to a patient's respiratory or breathing circuits or to a resuscitator.
