This page is about how your Pari PEP™ works, how to assemble it, carry out treatment and clean it.
How does the Pari PEP™ work?
This device uses PEP (positive expiratory pressure) which causes a resistance when you breathe out which helps keeps airways open. This allows air to get behind secretions so that the sputum can be cleared more easily. The adjustable ring has a series of different sized holes which will alter the resistance. Your physiotherapist will set the resistance that is appropriate for your chest and will review this regularly.
How to assemble the Pari PEP™


How to carry out your Pari PEP™ treatment?
- Take any inhalers/nebulisers as prescribed before you start your airway clearance to help prepare your airways
- Treatment can be carried out in relaxed sitting or in different positions as advised by your physiotherapist
- A pressure gauge may be added by your physiotherapist, this helps visualise how hard you should blow into the device.
- Place the mouthpiece in your mouth and create a seal around it with your lips.
- Slowly take a bigger breath in than normal through your nose/mouth, then pause for 2-3 seconds.
- Breathe out through the mouthpiece as far as is comfortable using a slightly stronger breath out than normal, but not too forceful.
- Return to relaxed breathing without the device for a short while.
- Complete huffs and cough/s as advised by your physiotherapist.
- Complete steps as prescribed by your physiotherapist ensuring you practice some relaxed breathing in between cycles.
- Take any inhalers/nebulisers after your airway clearance as prescribed
- This treatment can be combined with other airway clearance techniques such as Autogenic drainage as taught by your physiotherapist and certain nebulised solutions.
- Please bring your Pari PEP™ to clinic with you on a regular basis so that your physiotherapist can check whether it is in working order and review your technique.

Cleaning your Pari PEP™
- Clean all parts in a clean bowl with warm tap water and washing up liquid (except the manometer/tubing if you are using one) Rinse thoroughly with warm running tap water.
- Leave to dry in a clean and warm place.
- Keep the parts somewhere clean and dry such as a lunchbox.
- Once a week dismantle the Pari PEP™ (except the pressure gauge, connector and extension tube) and place in a pan of water and boil for 10 minutes. Dry thoroughly and store somewhere dry and clean as above.
