1. A gas sampling system comprising:

  • a first housing comprising a sensor assembly, wherein the sensor assembly is configured to measure a gaseous molecular species in a gas mixture, and wherein the first housing is configured to removably engage an airway adapter configured for insertion into a breathing circuit in fluid communication with a subject, and further comprising on an outer surface of the first housing, a first physical interface component and a second physical interface component; and

    a second housing comprising a pump, a pump inlet configured to reversibly receive a portion of the airway adapter, a pump outlet, and further comprising, formed in an outer surface of the second housing, a first physical interface component complementary to the first physical interface component of the first housing, and a second physical interface component complementary to the second physical interface component of the first housing, wherein the first housing and the second housing are further configured to removably couple with each other via the physical interface components such that a processing component in the first housing is configured to control operation of the pump in the second housing, wherein at least one set of complementary physical interface components are configured such that the processing component in the first housing is in wired communication with the pump of the second housing via the at least one set of complementary physical interface components;

    wherein the first and second housings are configured to engage the airway adapter such that operation of the pump in the second housing pulls gas into the first housing where the gas is measured by the sensor assembly, and then into the second housing via the pump inlet, and wherein the second housing is configured to exhaust the measured gas via the pump outlet of the second housing.
