Peak Flow Meter

• Every adult asthmatic should have a peak flow meter.
• A peak flow meter is a device that measures how well air moves out of your lungs.
• The number that is obtained is called the peak expiratory flow rate (PEFR).
• The "personal best" value is the highest PEFR number that a person obtains when they are feeling well.

• STEP 1 - Move the indicator to the bottom of the numbered scale. Stand up.

• STEP 4 - Blow out as hard and fast as you can.
• STEP 5 - Repeat the process two more times.
• STEP 6 - Write down the highest of the three numbers.

Using a Peak Flow Meter to Determine the Severity of an Asthma Attack

• GREEN Zone - MILD Attack: PEFR 80-100% of personal best
• YELLOW Zone - MODERATE Attack: PEFR 50-80%
• RED Zone - SEVERE Attack: PEFR less than 50%

And remember, contact your doctor if you develop any of the "Call Your Doctor" symptoms.
