ABSTRACT:
A conscious sedation system and a cannula and response testing assemblage for a conscious sedation system. In one embodiment, a controller generates a request for a predetermined response from a patient and analyses at least a response made by the patient to the request to determine a level of sedation of the patient. A cannula is disposable on the face of the patient for monitoring the breathing of the patient. A request assembly communicates to the patient the request generated by the controller. A response assembly senses the response and communicates the response to the controller. At least a part of at least one of the request and response assemblies is supported by the cannula. In another embodiment, the cannula itself is used as the response assembly wherein the response is a breathing response of the patient to the request.
