We claim: 1. A method for providing a dose of a gaseous drug to a patient that has a respiratory disorder comprising:(a) determining a normal resting breath rate for the patient; with a control circuit including a vacuum sensor, a microprocessor and an internal clock, by:(i) sensing transitions between patient inhalations and exhalations,(ii) monitoring and tracking the transitions,(iii) calculating a current breath rate of the patient,(iv) monitoring the current breath rate and determining a filtered normal resting rate specific to the patient by excluding her breath rates, and(v) calculating a new normal resting breath rate by combining the current normal resting breath rate and the current breath rate with an algorithm and weighting them respectively to provide a new normal resting breath rate;(b) comparing the current breath rate with the normal resting breath rate; and(c) providing a dose of the gaseous drug based on the comparison of the current breath rate with the normal breath rate.
