Our Mission

As our aging population grows, so does the prevalence of respiratory-related ailments. To meet this medical need, a variety of new respiratory diagnostic and treatment options are being developed. With the availability of these new options, respiratory care professionals will require the most up-to-date, scientifically- and clinically-based information to help them make informed decisions on what is best for their patients.


Clinical Foundations provides practical, clinically- and evidenced-based articles, case studies and symposia for respiratory therapists and respiratory care directors, managers, and supervisors. Clinical Foundations is based on a patient-focused model of care that emphasizes the need to provide the care and services that focus on patients’ individual needs and preferences.


As part of our commitment to helping respiratory care professionals improve their skills, each edition of Clinical Foundations is fully accredited by the AARC for CRCEs.

Oscillating Positive Expiratory Pressure,
(OPEP) Therapy

David M. Wheeler M. Ed., RRT-NPS


“To know even one life has breathed easier because you have lived. This is to have succeeded.”

                                        – Ralph Waldo Emerson


Oscillating positive expiratory pressure, (OPEP) is a therapeutic method which facilitates airway clearance through the combination of positive expiratory pressure and airflow oscillations during an active exhalation.,, OPEP devices have been described in the literature since the late 1990’s as cost effective secretion clearance alternatives to the labor and time consuming interventions such as: postural drainage, percussion and vibration.3


There are several types of OPEP devices on the market. The quality of the airflow oscillations and pressure thresholds are dependent on the device design and the ability of the patient to generate flow during an active exhaled maneuver, or maneuver that engages the muscles to assist with the flow of gas from the lungs. Thus, the device and the patient work together to produce the therapeutic effect of airway clearance.3,
