摘要：
A nasal mask has exhalation scoop fixed adjacent a lower portion of mask, adapted to overlie an upper lip of a patient when the mask is worn. The mask includes ports for sampling flow of CO2 expelled from the mouth and nose of the patient to the end-port, and a pressure-based flow resistor for balancing flow of CO2 expelled from the mouth and the nose of the patient.
