Mechanics of Measurements of Blow through the mouth quickly and strongly into the device in 1 Respiration Pulmonary Function breath, attempting to empty the lungs V. References ○ Make sure to blow through the mouth and not through the nose I. PEAK FLOW METER Handheld device used to measure the best effort of a patient in exhaling air forcefully from the lungs Prescribed by physicians to patients for monitoring of moderate-to-severe asthma as part of a patient’s asthma management plan ○ NOT used for COPD due to lack of data Patients aged 5 and above are usually able to use the devices with instruction and coordination from their primary physician or family member and recording important values in their diary Peak flow meter should be performed twice daily Figure 3. Blowing fast and lip-tight on the mouthpiece Step 3 Note the number indicated by the marker in the device after exhalation ○ Write the number down in peak flow diary Step 4 Reset marker of the device and repeat procedure for a total of 3 times Indicate in the peak flow diary the highest result from the 3 trials (called “personal best”) Indicate in recording experienced symptoms and time of the day result as recorded Step 5 Dispose of the used mouthpiece Figure 1. Peak Flow Meter D. INTERPRETING THE RESULTS A. IMPORTANCE The measurement of a patient’s peak flow will be compared with Results and trends recorded from this simple test may have their personal best value multiple uses including but not limited to: A peak flow meter has three (3) zones of measurement ○ Adjustment of daily medication on follow up Results vary depending on the height, sex, age, and race ○ Monitoring of symptoms to observe for changes in severity ○ Identify possible triggers to episodes Green Zone Designed to be convenient and easy for asthma self management 80-100% of a patient’s normal result ○ Can be used at home Suggests good control ○ Should be used with other methods as it does NOT solely Yellow Zone determine the status of the patient’s asthma 50-80% of a patient’s normal result B. PEAK EXPIRATORY FLOW May be accompanied by worsening symptoms Two important values: Indicate need for additional treatment or change in current ○ Predicted value treatment regimen Theoretical values that depend on the patient’s physical profile Red Zone and demographic
