Apparatus and method of sampling gas from a patient using a gas sampling assembly that include a patient interface assembly having a patient interface portion and a first gas sampling tube. The patient interface portion communicates with an airway of a patient and is attached to a first end of the first gas sampling tube so that the patient interface assembly is a unitary component. A second gas sampling tube is releasably engageable with the second end of the first gas sampling tube such that substantially smooth and undisturbed fluid flow is maintained between the first gas sampling tube and the second gas sampling tube. The second gas sampling tube connects to a gas sensor and can be used with other patient interface assemblies. |
