1. An oscillating positive expiratory pressure system comprising:
an oscillating positive expiratory pressure device comprising an inhalation port and a mouthpiece defining a chamber, wherein the chamber and the inhalation port are separated by a one-way valve;
a first sensor in communication with the chamber, wherein the first sensor is configured to sense an exhalation flow and/or pressure and generate a first input signal correlated to the exhalation flow or pressure;
a second sensor in communication with the inhalation port, wherein the second sensor is configured to sense an inhalation flow and/or pressure and generate a second input signal correlated to the inhalation flow or pressure;
a processor configured to receive and compare the first and second input signals from the first and second sensors and generate an I:E value, wherein the processor is configured to compare the I:E value with an upper limit and a lower limit; and
an output component configured to: (1) provide a first feedback when the I:E value is greater than the upper limit, (2) provide a second feedback when the I:E value is less than the lower limit, and (3) provide a third feedback when the I:E value is equal to or between the upper and lower limits.
