Zusammenfassung:	A system for delivering an aerosolized drug to a patient includes an aerosol drug generator coupled to a mouthpiece including two sensing ports. A pressure sensor is connected to the two sensing ports of the mouthpiece. The system also includes a data processing component which calculates an inspired flow rate based on a signal from the pressure sensor, and a measurement component which measures the inhalation time, which is the time during which the aerosolized drug is inhaled at the inspired flow rate. The data processing component also calculates the amount of the aerosolized drug delivered to the patient based on the inspired flow rate, the amount of inhalation time, and a drug delivery coefficient.
