Abstract: An apparatus including a tubular channel having a pathway extending between a proximal end and a distal end of the tubular channel. The proximal end is configured to connect directly or indirectly to an end tidal CO2 monitor. The distal end has an opening. The apparatus further includes a detection member including a chamber disposed in fluid communication with the pathway of the tubular channel such that gas entering the tubular channel via the opening on the distal end passes into the chamber. A detection element is disposed within the chamber and includes a component that is sensitive to one or more systemic biomarkers such that, upon exposure to a predetermined concentration level of the one or more systemic biomarkers contained in the gas, a state of the detection element experiences a permanent alteration and the detection member indicates that the predetermined concentration level of the one or more systemic biomarkers is present in the gas.

Abstract: An apparatus may include a controller that may include one or more processors, and memory storing executable instructions that, when executed by the one or more processors, may cause the one or more processors to perform operations. The operations may include receiving key fob data from a reader. The key fob data may include ID information of a user. The operations may further include determining authorization privileges associated with the received ID information of the user, and controlling a lock system of a gas flow valve in response to the determination of the authorization privileges associated with the received ID information of the user.
