DIRECTIONS
Before First Use: Instructions on how to find your "personal best" peak flow number (usually by taking readings daily for 2-3 weeks when asthma is well-controlled).
How to Take a Reading:
Move the marker to the bottom of the numbered scale.
Stand up straight.
Take a deep breath, filling your lungs completely.
Place the mouthpiece in your mouth, between your teeth, and close your lips tightly around it. Do not block the hole with your tongue.
Blow out as hard and fast as you can in a single, quick burst.
Note the number where the marker stopped.
Repeat the process two more times and record the highest of the three readings.
When to Take Readings: Typically advised to take readings every morning (before medication) and/or when symptoms occur, or as directed by a healthcare professional.
Interpreting Readings: Guidance on what readings in the Green, Yellow, and Red zones indicate and what actions to take based on your Asthma Action Plan (developed with a doctor).
Record Keeping: Advise to keep a log of readings.
