1. An oscillating positive expiratory pressure apparatus comprising:
a housing defining a chamber,
a chamber inlet configured to receive exhaled air into the chamber;
a chamber outlet configured to permit exhaled air to exit the chamber;
a respiratory portal configured to receive an aerosol medicament into the chamber from a nebulizer configured to deliver aerosol therapy; and,
a one-way valve configured to permit the aerosol medicament to enter the chamber;
an inhalation flow path defined between the one-way valve and the chamber inlet; and,
a moveable oscillation member positioned in the inhalation flow path;
wherein the one-way valve is configured to remain closed during administration of oscillating positive expiratory pressure therapy, and is configured to open when the aerosol medicament is received into the chamber, thereby allowing a user to perform both oscillating positive expiratory pressure therapy and aerosol therapy during a respiratory cycle.
