A system for setting a medically prescribed treatment regime on a hand held inhalator device is disclosed that includes the hand held inhalator device having a transmitter/receiver configured to receive data from a medical practitioner device and send data to the medical practitioner device as well as a trigger configured to dispense medication from a medication source into a chamber of the inhalator device after a threshold level of positive pressure is achieved within the chamber and maintained for a predetermined period of time. A medical practitioner application programming interface is used to configure the predetermined period of time and the second threshold level of positive pressure of the hand held inhalator device required to actuate the trigger and dispense medication.
