Interesting. Here is a cut and paste of the instructions that I have:
Using your PEP device
1. If this is the first time you will use your PEP device, the respiratory therapist or nurse will determine on what level your frequency adjustment dial should be set. With each use, make sure the dial is on this setting.
2. Sit with elbows resting on a table and relax.
3. Take in a deep breath and hold it for 2 - 3 seconds.
4. Place the mouthpiece lightly in mouth. Breathe out (exhale) through the PEP device slowly and smoothly. Be sure to keep a tight seal on the mouthpiece when breathing out.
5. Perform 10 - 20 breaths with each use. You should use your PEP device 4 - 6 times per day.
But it sounds like most people just adjust it to what feels right.
