## Description

From the manufacturer The Microlife Digital Peak Flow Meter with FEV1 is the doctor's choice for managing diseases that restrict lung performance. This advanced meter for spirometry includes a digital diary and measures air flow velocity and volume (FEV1) to indicate early warning signs for impending asthmatic incidents or conditions. Using these measurements in conjunction with a doctor's consultation allows patients with asthma, COPD and other lung diseases to manage their condition. What is PEF: PEF is Peak Expiratory Flow, or in other words measures how fast you can push air out of your lungs. What is FEV: FEV is Forced Expiratory Volume, or in other words measures how much air a person can exhale during a forced breath. Who should use this meter? Asthmatics Chronic Obstructive Pulmonary Disease (COPD) Other Respiratory Problems Athletes Superior digital accuracy Accuracy: Superior to mechanical methods, digital peak flow meters provide an exact reading, avoiding any accidental mistakes. The meter measures the flow rate at one hundredths of a liter per minute, and the results are automatically recorded. Consistent and accurate readings will improve your ability to accurately know your condition. Memory: Automatically stores 240 readings The highest reading from each session is automatically stored, allowing you to test multiple times and record your best result. Reports show that patients who measure and record their readings are better able to monitor and manage their conditions. Peak Flow and FEV1 tracking software Connect your meter to your PC and automatically download your readings. With the user friendly analysis software, you can chart your progress print graphs make notes about your symptoms or triggers export your results to a spreadsheet share your result with your health care provider Use & Care How to take a measurement Step 1: Standing up, hold the peak flow meter as shown with both hands. Step 2: Take a deep breath and blow into the mouthpiece as hard as you can for as long as possible. Step 3: As you exhale, bend forward as shown to push all the air from your lungs. Step 4: Measure your peak flow rate twice daily and close to the same time each day. Complete instructions in English/Spanish included. How does the risk indicator work? Whether you are using national standards, or your own customized numbers, the green, yellow and red bars on the display are a quick visual reference to show how your results compare. As your peak flow raises or lowers, the arrow on the display will show the measurement as within the normal (green), borderline (yellow) or in the danger (red) range. What do the colors mean? Green = 80% or higher than your personal best Yellow = 60 - 79% of your personal best Red = 50 - 59% of your personal best How do I clean my monitor? Simply separate the mouthpiece and measuring tube from the meter, then clean the parts with soap & warm water. Air dry. Removable mouthpiece Designed for all ages, this monitor comes with 3 color coded mouthpieces. Use them to monitor yourself and your child, or rotate them between uses for cleaning. Specifications
