DR Burton Healthcare Products, the makers of the vPEP® Oscillating Positive Expiratory Pressure device, was recently featured in a Respiratory Therapy journal article.

“Analysis of Three Oscillating Positive Expiratory Pressure Devices During Simulated Breathing“ was published in the winter issue of the journal and written by Doug Pursley, MEd, RRT-ACCS, FAARC.

In the study, a human lung simulator analyzed maximum expiratory flow during OPEP therapy by comparing flow-volume loops generated by the DR Burton vPEP device and two other OPEP products.  

Pursley focused on peak expiratory flow, which is a major factor in improving secretion. The device indicated OPEP effectiveness in secretion clearance.


“The study showed the superiority of the vPEP across five tidal volumes, which indicates superior secretion clearance ability even for patients with low tidal volume,” said Dennis Cook, BSRT, RRT, and CEO of D R Burton. “The vPEP is also an easy device to clean for patients with only four parts, making it easier to help reduce risk of infection.”
