Your Personal Breathing Coach

PEP Buddy is a small, easy-to-use, hands-free, device held in the mouth. By breathing out through PEP Buddy, exhalation is prolonged, and your breathing rate slows. PEP Buddy is a simple, innovative, and portable medical device that reduces breathlessness so you can increase your activity level.

What is PEP Buddy?

 A light-weight, handsfree, positive expiratory pressure (PEP) device

 Attached to a lanyard for easy accessibility and held in mouth like a whistle

 Designed for use during activities and rest

 Various grades of PEP available

How It Works

PEP-Buddy works through 4 mechanisms:

1  It provides positive pressure during exhalation (back pressure), which keeps the airways open to prevent air trapping and airway collapse.

2  It slows down the respiratory rate.

3  It prolongs exhalation time.

4 It provides a point of focus for breathing.

These mechanisms help reduce dynamic hyperinflation and its consequences during activities. Hence improving dyspnea, oxygenation, and exercise tolerance. Such breathing pattern also help reduce stress and anxiety.
