Education is the Focus

  • The changing arena of health care has brought more attention to all areas of medicine. Funds are tight and Gasshead wanted to continue to maintain its focus on education.
  • In the true spirit of making education available to all users throughout the world, Gasshead has dramatically reduced the cost of the full version of ACTc to just $9.99.
    • This low fee assists in general maintenance and funds future projects.
  • ACTc is available also available in a Lite version which has temporary popup messages

Note: On each screen, ACTc has a “Help” button which explains in detail the research that establishes the calculation and thought flow of that specific screen. A complete list of references can be found in the About US section under “Readings” as well as list of some of our testers who took their valuable time to assist in ACTc’s development.


Legal Notice: ACTc is an educational tool that stresses many important aspects of the science of anesthesia. It accomplishes this by showing the multiplicities and connections of the daily calculations that every anesthesia provider uses for each case. Each calculation is further explained in detailed within each help section. Every effort has been made to ensure that the proper information has been provided to assist in the educational aspect of this program. Your use of ACTc releases its developers and Gasshead from any liability from ACTc use or misuse. ACTc is intended for education use only and is not intended to replace or dictate clinical decisions by trained anesthesia providers. Gasshead wishes the best of luck to all of its users.
