1. A nasal mask comprising:
an inner surface forming a nasal chamber;
a ventilation port that extends from an upper portion of the nasal mask in a first direction;
an end-tidal CO2 port that extends from the upper portion of the nasal mask and comprises an opening adjacent a lower portion of the nasal mask; and
an exhalation scoop fixed adjacent the lower portion of the nasal mask and adapted to overlie an upper lip of a patient when the nasal mask is worn;
wherein the opening is located behind the exhalation scoop for sampling CO2 expelled from a mouth of the patient, and the exhalation scoop is formed of a material that is flexible relative to a material that defines the nasal chamber such that the exhalation scoop is adapted to be folded back in the first direction toward the nasal chamber to permit access to the mouth of the patient.
