Patent ID: 8061353

Claim:
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.
