1. An apparatus, comprising:
a tubular channel having a pathway extending between a proximal end and a distal end of the tubular channel, the proximal end being configured to connect directly or indirectly to an end tidal CO2 monitor, and the distal end having an opening;
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, and
a detection element disposed within the chamber, the detection element including 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 as an indication that the predetermined concentration level of the one or more systemic biomarkers is present in the gas;
a cannula channel that extends from a side of the detection member in a direction transverse to the pathway of the tubular channel, the cannula channel being configured to allow a nasal cannula to be inserted laterally therein such that the nasal cannula extends in a same direction as the pathway of the tubular channel; and
a movable obstruction element that, in a first position, permits insertion of the nasal cannula into the cannula channel, and when moved from the first position into a second position, impedes removal of the nasal cannula without pinching the nasal cannula when the nasal cannula is inserted in the cannula channel,
wherein the cannula channel includes a slot having a width as wide as a diameter of the nasal cannula and a thickness as thick as the detection member, the slot extending longitudinally from an outer wall of the detection member toward the chamber and curving to extend away from the chamber before terminating within the outer wall of the detection member,
wherein the detection member further includes a protrusion on a side thereof, the protrusion extending around the tubular channel and having a threaded external surface,
wherein the obstruction element is a cylindrical collar having threads on an internal surface, a first side of the collar having a hole therein through which the first end of the tubular channel extends, and a second side of the collar facing the detection member,
wherein, in the first position, the collar is disconnected from the detection member and the nasal cannula is insertable into the slot, and
wherein, in the second position, the collar is connected to the detection member, via engagement between the threads on the internal surface of the collar and the threaded external surface of the protrusion on the side of the detection member, and the nasal cannula is fixed in place via pressure between a sidewall of the slot and an exterior side wall of the collar.
