Designed to be used with a CO₂ capnograph monitor system, this mask and adapter combination allows clinicians to comply with state and national health-care organizations’ guidelines regarding capnograph monitoring during moderate-to-deep sedation and general anesthesia. Mask-in-mask design draws excess gas into vacuum, reducing ambient nitrous oxide. Transparent outer hood provides visual of nose breathing. Low profile improves clinician’s view and access to oral cavity. Capnography adapter allows for flexibility in connecting to either left or right side of the mask. Capnography sampling takes place within the nasal mask and directly measures patient’s exhalations at the source. Recyclable. Not made with natural rubber latex.
