Abstract
The invention provides a narcotic dosage calculating method for an anesthetic machine. The narcotic dosage calculating method comprises steps of measuring the concentration of the narcotic gas and the mixed gas flow, and recoding the measuring time; calculating the dosage of the gas narcotic depending on the concentration of the narcotic gas, the mixed gas flow and the measuring time; and recognizing the type of the narcotic gas. A main controller can be used for calculating the dosage of a liquid narcotic corresponding to the dosage of the gas narcotic, based on a method for calculating a molar volume of gas. The narcotic dosage calculating method for an anesthetic machine is advantageous in that a large error caused by manual computation can be reduced.
