1. An apparatus for inducing a pediatric patient to inhale a fluid pharmacological agent while breathing gas through a face mask, comprising:
- a. a fluid conduit having a first end, a second end, and a rotor housing, said first end capable of being coupled to a source of fluid pharmacological agent and said second end capable of being coupled to a face mask sized to fit a pediatric patient such that fluid pharmacological agent flowing through said conduit can enter a face mask, said rotor housing comprising a first port and a second port positioned on opposite sides of said housing and offset from the center of said housing;
said conduit having sufficient diameter to allow fluid pharmacological agent to flow through said conduit at a sufficient flow rate to be inhaled by a pediatric patient;
b. a turbine driven rotor in said rotor housing, said rotor comprising a first end in said fluid conduit, a second end extending outside said fluid conduit, and at least two turbine blades affixed to the first end; and
c. a visual stimulator affixed to the second end of said rotor such that said stimulator moves when said rotor rotates, and said stimulator being of sufficient size such that its movement is visible to a pediatric patient breathing ventilatory gases through a face mask.
