Revolutionary digital peak flow meter

Experience the comfort of a digital peak flow meter with the revolutionary Smart Peak Flow! It has scientifically been proven that the Smart Peak Flow guarantees more accurate measurements than mechanical peak flow meters ¹. Use the device with the app and connect it to your smartphone or tablet. The app processes your results and automatically records them. This will save you a lot of time on a daily basis. Thanks to its compact size, you can take the Smart Peak Flow with you wherever you go.

Connecting the Smart Peak Flow to your smartphone or tablet

There are different versions of the Smart Peak Flow. You can connect your devices to each other wirelessly and hold the peak flow meter in your hand using the included handle (or the audio jack) if you choose the Bluetooth version. Download the free app and start managing your asthma! The other version is not wireless but uses the audio jack of your smartphone or tablet: simply plug the Smart Peak Flow into the audio jack! Please note that you’ll need an adapter if your smartphone doesn’t have an audio jack. Consult your smartphone manual for more information.

TIP: use the Smart Asthma app on your smartwatch and get notified when you need to measure your peak flow!

Predicting future asthma attacks

The Smart Peak Flow is a very useful device that allows you to gain insight into your lung capacity for the next day. If you also fill in how often you use your inhalator, the app will be able to predict asthma attacks. Are you going to measure your peak flow? Take a deep breath and blow powerfully into the mouthpiece. It is the speed and force of your exhaled breath that counts, not the length of it. After blowing, the peak expiratory flow (PEF) appears in liters per minute. You’ll also see how this result relates to your "Personal Best", the best value you have blown up to that point. The app asks you to perform three blows and will save the highest of those values as the result. Depending on your result, the "traffic light" will be green (asthma under control), amber (caution) or red (medical emergency).

Monitoring your lung function over a longer period of time

The app automatically saves your daily results. This helps you to monitor your lung function over a longer period of time: weekly, quarterly or annually. Would you like to perform a peak flow measurement on different locations and compare the results (at home, at work, during exercise…)? Then give the app access to your location.

"Download – Blow – Track – Share!"

User friendly app

5 tips and tricks

1. Put your lips around the mouthpiece and place it past the teeth.
2. Always stand upright when measuring your peak flow.
3. Use the Smart Peak Flow in a room with ample sunlight or artificial light. The peak flow meter needs sufficient light to be able to perform an accurate measurement.
4. Clean the Smart Peak Flow and the mouthpiece with warm water and Pürdoux soap. It shouldn’t be cleaned with normal soap. Dry with a soft cloth.
5. Never lend your Smart Peak flow to another person because of the risk of cross-contamination.
