PEP Therapy

Westmed offers an inexpensive, easy-to-implement, and time-saving solution for providing PEP during aerosol therapy with the Circulaire II aerosol delivery system, or airway clearance with the Vibralung Acoustical Percussor.  Westmed’s Variable Expiratory Resistor provides PEP which promotes lung expansion and airway clearance.

PEP Therapy is built into the Circulaire II Aerosol Delivery Device and the Vibralung Acoustical Percussor

PEP is the acronym for Positive Expiratory Pressure, the technique of applying resistance to the exhalation phase of breathing in order to slow expiratory flow, build up a modest amount of back-pressure, slightly prolong the expiratory phase and dilate and “splint” the airways and alveoli. In so doing, a number of therapeutic benefits are conferred to the patient:

1. Prevent small airway collapse.
2. Promote airway clearance through airway dilation.
3. Promote lung expansion.
4. Improve aerosol distribution and deposition when used concomitantly with aerosol delivery.
Pursed-lips breathing, or use of a fixed-orifice resistor, such as a PEP device, creates back-pressure that splints the airways open during exhalation.

 

 

All Circulaire II High-Efficiency Aerosol Drug Delivery and Vibralung Acoustical Percussor systems include a Variable Expiratory Resistor that allows the cross-sectional area of the exhalation port to be varied from a “wide open” zero resistance position to a “closed down” position that slightly restricts expiratory airflow and imposes a small amount of PEP (0 to ~5 cmH2O) during quiet breathing.

“Classic” PEP Maneuver

The most potentially beneficial application of PEP is to have the patient perform the “classic” PEP maneuver from approximately 80% of Total Lung Capacity. This can be done while the patient is breathing on the Circulaire or Vibralung. The PEP Resistor with Manometer should be used so the patient will have the visual feedback of the manometer available. The manometer should be oriented so that the patient can see the red pointer movement within the manometer tube, and hold it between 10 and 20 cmH2O during the maneuver for a few seconds as directed by the respiratory therapist.
