A medical anesthesia machine is designed to deliver drugs that help to eliminate pain and other unwanted sensations. The continuous flow anesthetic machine provides an accurate and constant supply of medical gases (such as air, oxygen and nitrous oxide), mixed with an accurate concentration of anesthetic vapor (such as isoflurane), and delivers this mixture to the patient at a desired pressure and flow.

Honeywell manufactures many products that may be used in anesthesia machines. They are designed to help control pressure, airflow and temperature.
