In a vaporizer a volatile anesthetic liquid is evaporated into a gas which eventually flows to the patient. A lot of attention is directed toward temperature maintenance in order to assure that the patient receives the proper concentration. Why is temperature control important? What methods can be used to actually control the temperature? What does splitting ratio mean and what role does it play?
The vapor pressure of the anesthetic (which determines how much of the anesthetic goes into the gas) depends on the type of anesthetic used and the temperature. Since the type of anesthetic is already predetermined, the only variable to control vapor pressure is the temperature. ...
This solution looks at anesthetic vaporization and its controlled delivery.
