The primer purpose of a vaporizer machine is adding anesthetic vapor into the fresh gas flow. It’s done in such a way that the output delivers the set anesthetic agent concentration in the most accurate way. Soon fresh gas enters the inlet and gets divided into two pathways. Here things depend on the setting of the control dial. The fresh gas never comes into contact with the vapor, but still it gets fully saturated with vapor. At the exit the gas meets the chamber gas and they two mix. The output of the process depends on how much of fresh gas went through the pathways.
An anesthesia vaporizer machine is one of the most critical components of the whole anesthetic machine. It produces a predictable and controlled concentration of vapor in the gas that passes through the vaporizer.
