Monitor Mask is a Seattle, Washington medical device company founded with the mission of creating capnography oxygen face masks to increase patient safety and streamline workflows. The first design, the M1 Capnography Mask, was imagined in the spring of 2011 and served as the inspiration for the CapnoVue face mask series. Since then, the mask has been produced and sold in infant, child and adult sizes throughout the United States. A new product, the Scope Capnography Mask, was  added to our product line to address customer needs.

CapnoVue devices facilitate capnography in medical practice, increase patient safety, make care workflows more efficient, and help clinicians meet monitoring standards.
