A respiratory delivery care system featuring a mechanical flow indicator movable in response to inhalation and/or exhalation by a user, and an electronic indicator operable in response to an electronic signal transmitted in response to the movement of the flow indicator. The flow indicator is an inhalation valve, exhalation valve, or an axially movable actuator. A delivery device includes a holding chamber wrapped by a coil and at least one magnet disposed within the center of the coil and reciprocally movable to induce a current and store it in a supercapacitor coupled to a circuit and an electronic indicator. A respiratory delivery device featuring a flow indicator configured to send a first input signal, a metered dose inhaler communicating with a holding chamber, a lever to actuate the inhaler and having a sensor to send a second input signal, and a processor operative to receive these signals to generate an output signal.
