Patent ID: 8261738

Claim:
A method for maintaining a consistent treatment time for aerosol drug delivery treatments, comprising: administering a predetermined dose of aerosolized drug to a patient using an aerosol generator, the aerosol generator operating in pulses to deliver the aerosolized drug to the patient in pulses, and the aerosol generator operating at an initial power level during a first set of pulses; monitoring the patient's breathing pattern during the first set of pulses; and varying the power level at which the aerosol generator operates during a second set of one or more pulses based on the monitored breathing pattern in order to maintain the consistent treatment time, wherein the breathing pattern includes a ratio of the patient's inhalation with respect to exhalation, and wherein varying the power level includes increasing the power level for the second set of one or more pulses responsive to the ratio falling below a predetermined threshold during the first set of pulses.
