Capnotherapy refers to the use of CO2 capnometry-assisted feedback tool to encourage healthy breathing and self-regulated control of the challenges of disorders associated with breath and emotion. Capnotherapy may occur on its own, in concert with other approaches, or as part of an integrated consciousness-raising treatment curriculum.

Portable capnometers can provide for in-home training and software exists to provide effective monitoring and training over the internet. Such training is not necessarily limited to one-to-one work but may be applied on a larger scale holding incredible potential for employment and assistance programs.
