Hello! I have used both a PEP and the Vest [among others], so I wanted to weigh in here. Traditionally, hand PDs really are the best. There is a machine called the IPV machine which worked particularly well for me, also. However, specifically, the PEP, in my mind, is something of an alternative to chest therapy rather than chest physiotherapy for its own sake. For example, after my PDs were completed, I would sometimes use a mask to assist in getting a bit of extra clearance. The Vest, at the end of the day has the most power though - as long as you interact with it. PDs are easier because they require less effort on your part, but if you are energetic and proactive - the Vest can really pack a whollop.

<br>I have a blog of my own where I once covered the Vest, if you care to read about what goes on in my brain about such matters: <a target="_blank" title="Breathe Easy - The Art of Coughing" href="http://http://gwpoland.wordpress.com/2010/11/28/the-art-of-coughing/">http://gwpoland.wordpress.com/2010/11/28/the-art-of-coughing/

<br>Blessings to you, and best of luck!
