1. An airway adjunct adapted to secure to an airway device, the airway device having a first end, a second end opposite the first end, and an internal airway volume defined by a single continuous channel with one or more internal-facing surfaces extending from the first end to the second end, the airway adjunct comprising:
a body that is configured to be removably coupled to the first end of the airway device, the body including
a first opening extending through the body and configured to be in fluid communication with the internal airway volume,
a second opening extending through the body and configured to be in fluid communication with the internal airway volume,
a third opening extending through the body and configured to be in fluid communication with the internal airway volume,
a first cross-member positioned between the first opening and the second opening, and
a second cross-member positioned between the second opening and the third opening;
a gas administration tube extending through the first cross-member such that the gas administration tube is positioned between the first opening and the second opening and comprising a first internal terminal end configured to be centrally positioned relative to the internal airway volume of the airway device such that the first terminal end is configured to be spaced apart from the internal-facing surfaces of the single continuous channel and a first port, the gas administration tube holding the first port in a fixed position relative to the airway device;
a gas sampling tube extending through the second cross-member such that the gas sampling tube is positioned between the second opening and the third opening and comprising a second internal terminal end configured to be positioned centrally relative to the internal airway volume of the airway device such that the second internal terminal end is configured to be spaced apart from the internal-facing surfaces of the single continuous channel and a second port, the gas sampling tube holding the second port in a fixed position relative to the airway device;
wherein the first internal terminal end is spaced apart from the body by a first distance and the second internal terminal end is spaced apart from the body by a second distance that is greater than the first distance, such that the second internal terminal end is positioned further into the airway device than the first internal terminal end,
wherein the first cross-member and the second cross-member are configured not to extend within the single continuous channel, and
wherein when the body is attached to the first end of the airway device, the single continuous channel of the airway device is unobstructed from the first internal terminal end of the gas administration tube and the second internal terminal end of the gas sampling tube.
