Claim 8:
9. A method of delivering medicine for optimizing medicine delivery to a user, the method comprising:
providing an inhaler having a detachable cap, the detachable cap adapted to removably receive the inhaler, the detachable cap comprising:
a hollow receiving portion adapted to removably receive the inhaler and comprising a rigid roof portion and a rigid side surface, wherein the hollow receiving portion is configured to snugly fit an outer body of the inhaler;
a vent formed in the roof portion of the detachable cap to allow a flow of inhaled air through the detachable cap to the inhaler, the vent defined by a fixed size opening through the roof portion, wherein a height of the cap and the size of the vent are configured to facilitate laminar air flow through the cap and vent, wherein structure of the detachable cap is configured to create pressure difference to flow of inhaled air during use of the inhaler;
a pressure sensor inside the detachable cap, underneath the roof portion, and adjacent to the vent, wherein the pressure sensor comprises a pressure sensor port situated on the outside of the detachable cap, the pressure sensor adapted to detect a first internal air pressure within the detachable cap, underneath the roof portion, and adjacent to the vent, and the pressure sensor port adapted to detect a first ambient pressure outside the cap;

providing an electronic circuit communicatively coupled to the pressure sensor;
receiving, by the electronic circuit, the first internal air pressure and the first ambient pressure from the pressure sensor;
calculating, by the electronic circuit, an inhaled air flow rate through the detachable cap based on the difference between the first detected ambient pressure and first detected internal air pressure based on Bernoulli's principle; and
providing, by the electronic circuit, recommendation to the user for optimizing medicine delivery, wherein the recommendation is based on the calculated air flow rate.
