1. A method of providing feedback regarding administration of oscillating positive expiratory pressure (“OPEP”) therapy, the method comprising:
receiving an oscillating air pressure through a conduit in fluid communication with an OPEP device;
dampening the oscillating air pressure with a pressure stabilizing orifice, the pressure stabilizing orifice having a cross-sectional area between 0.196 mm2 and 1.767 mm2;
sensing the dampened oscillating air pressure; and,
providing feedback regarding the dampened oscillating air pressure.
 
14. A method of providing feedback regarding administration of oscillating positive expiratory pressure (“OPEP”) therapy, the method comprising:
receiving an oscillating air pressure through a conduit in fluid communication with an OPEP device;
dampening the oscillating air pressure with a pressure stabilizing orifice having a cross-sectional area between 0.196 mm2 and 1.767 mm2;
sensing the dampened oscillating air pressure;
providing feedback regarding the dampened oscillating air pressure to a user of the OPEP device; and,
adjusting an administration parameter of OPEP therapy based on the feedback.
 
19. A method of providing feedback regarding administration of oscillating positive expiratory pressure (“OPEP”) therapy, the method comprising:
receiving an oscillating air pressure through a conduit in fluid communication with an OPEP device;
dampening the oscillating air pressure with a pressure stabilizing orifice, the pressure stabilizing orifice having a cross-sectional area between 0.196 mm2 and 1.767 mm2;
sensing the dampened oscillating air pressure; and,
providing feedback regarding the dampened oscillating air pressure to a caregiver to a user of the OPEP device; and,
monitoring the feedback during a predetermined period of time to determine whether appropriate dampened oscillating air pressure is achieved during the predetermined period of time.
