INSTRUCTION MANUAL Peak Flow Meter MODEL PF9940 INTRODUCTION TO THE PEAK-AIRTM PEAK FLOW METER The PEAK-AIR is a portable device for the measurement of peak expiratory flow rate (PEFR). It can be used by the patient at home, school, workplace, etc. Daily measurements of PEFR provide information to you and your doctor on small changes in your lung function, often to prevent the onset of an asthma attack. Your doctor will assist you in learning to properly perform the test and record the results, as well as providing a treatment plan based on the peak flow measurements. CAUTION Use PEAK-AIR under the guidance and supervision of a physician or other healthcare professional. Contact this person if you note a downward change in your readings indicating a worsening of your condition. WARRANTY PEAK-AIR is covered by a three year warranty. If found to be defective under normal use, the unit will be replaced free of charge. The National Asthma Education Program (NAEP) of the National Institutes of Health established technical standards for peak flow monitoring. These include documentation, accuracy and reproducibility requirements. PEAK-AIR and this pamphlet have been designed to meet these rigorous standards. HOW TO CLEAN YOUR PEAK-AIR PEAK FLOW METER The PEAK-AIR and the plastic mouthpieces may be hand washed. When hand washing, thoroughly drain and air dry the peak flow meter. It is not recommended to submerge the peak flow meter in water or to use solvents or strong cleaning solutions. Use only soap and water. If used in a home setting by a single patient, weekly washing is recommended. DO NOT BOIL. HOW TO USE YOUR PEAK-AIR PEAK FLOW METER Take a few moments to apply the accompanying personalized self-stick information labels and circle-shaped labels. Your physician will assist you in positioning the color zone labels along the scale. 1. Attach the appropriate size plastic mouthpiece on the input side of the peak flow meter, the side clearly marked with the arrow ( ). Both adult and pediatric mouthpieces are tapered. Please be sure to insert the wide end into the meter. 2. Make sure the sliding indicator is at the bottom (zero) side of the scale. 3. Hold the peak flow meter so that your fingers do not block the outlet opening or prevent the sliding indicator from moving the full length of the scale. It is best to grasp the meter around the round handle of the device. 4. While standing, inhale as deeply as possible, then place your mouth firmly around the mouthpiece, making sure that your lips form a tight deal. The mouthpiece should be inserted past the teeth. 5. BLOW OUT AS HARD AND FAST AS POSSIBLE, a short, sharp blast. This will cause the indicator to move up the scale. NOTE: you do not have to expel all of the air in your lungs, the indicator will most likely not move after the first few seconds of the effort. 6. The final position of the indicator is your PEFR (peak expiratory flow rate); make note of this value. 7. Repeat steps 2 through 6 until you have completed three efforts correctly. Allow a minute or so between efforts to rest. The variation between the readings should not exceed 10%. HOW TO USE YOUR PEAK-AIR PEAK FLOW METER 8. Record the highest of the three readings. DO NOT AVERAGE, in your PEFR readings personal log. Also record the date and time. 9. Compare the highest result with your personal best and calculate the percentage (divide the current highest PEFR by the personal best PEFR and multiply by 100). Check to see which zone you are currently in (green, yellow or red). Follow your physician's advice regarding your treatment for each zone (percentage of personal best) - green (80%-100%), yellow (50%-80%), red (0%-50%).

They follow the recommendations of the National Heart, Lung, and Blood Institute, National Asthma Education Program, Expert Panel Report - 1991. GREEN - No asthma symptoms are present and the routine plan for maintaining control can be followed. For patients on chronic medications, consistent readings in the green zone may indicate an opportunity to consider a reduction in medications. YELLOW - An acute exacerbation may be present and a temporary increase in medication may be indicated. RED - An immediate bronchodilator should be taken and the clinician should be notified if PEFR measures do not return immediately and stay in yellow or green zones. Use the PEAK-AIR under the guidance and supervision of a physician or other healthcare professional. Contact this person if you note a downward change in your readings indicating a worsening of your condition. BENEFITS OF PEAK FLOW MONITORING · Aids in the early detection of an impending asthma attack. · Measurement of reduced respiratory capacity such as during an allergic reaction. · Easy self-administration of the peak flow test can uncover harmful effects of air pollution and environmental or occupational hazards. · Portable convenience - package includes reusable mouthpiece and peak flow diary.
