1. An oscillating positive expiratory pressure device comprising:
a mouthpiece defining a longitudinal axis and having an end port;
a housing connected to the mouthpiece and having a top surface, wherein at least a portion of the top surface is longitudinally spaced from the end port and defines a viewing surface adapted to be visible to a user when the end port is disposed in a mouth of the user; and
a feedback array disposed on the viewing surface, wherein the feedback array extends diagonally across the viewing surface, wherein the feedback array is substantially linear, and wherein the feedback array comprises a plurality of spaced apart lights, wherein the plurality of lights comprises a first endmost light positioned closest to the end port and a second endmost light positioned furthest from the end port, and wherein the first endmost light is adapted to be illuminated in a first color indicating a user input that is below a predetermined acceptable range, wherein the second endmost light is adapted to be illuminated in a second color indicating the user input is above the predetermined acceptable range, and wherein at least one of the plurality of lights is positioned between the first and second endmost lights and is adapted to be illuminated in a third color indicating the user input is within the predetermined acceptable range.
