With a 240-reading memory, intuitive color-coded alerts, and PC connectivity including analysis software, it empowers asthma, COPD patients, and athletes to monitor lung function accurately. Lightweight and portable, it suits all ages and includes multiple mouthpieces and a carrying case for convenient daily use. ## Description 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. PEF is Peak Expiratory Flow, or in other words measures how fast you can push air out of your lungs. FEV is Forced Expiratory Volume, or in other words measures how much air a person can exhale during a forced breath. Asthmatics Chronic Obstructive Pulmonary Disease (COPD) Other Respiratory Problems Athletes 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. 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. 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 Standing up, hold the peak flow meter as shown with both hands. Take a deep breath and blow into the mouthpiece as hard as you can for as long as possible. As you exhale, bend forward as shown to push all the air from your lungs. Measure your peak flow rate twice daily and close to the same time each day. Complete instructions in English/Spanish included. 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. Green = 80% or higher than your personal best Yellow = 60 - 79% of your personal best Red = 50 - 59% of your personal best Simply separate the mouthpiece and measuring tube from the meter, then clean the parts with soap & warm water. Air dry. 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. ## Features - Peak Flow Pack Of 1 - High accuracy With peak expiratory flow (PEF) & FEV1 measurement. - 240 data memory Stores up to 240 measured values with date and time. - Result indicator Understand measurement data intuitively. - Rotating vane wheel method.Suitable for children and adults.Professional carrying bag.Battery driven.Equipped with wall holder.Software and connection cable included ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B000BH8TUA | | Best Sellers Rank | #79,587 in Health (See Top 100 in Health) #11 in Respiration Flow Meters | | Item Model Number | PF 100 | | Manufacturer | Microlife | | Product Dimensions | 19.05 x 13.97 x 10.16 cm; 150 g | ## Images ![Microlife Pf-100 Microlife Peak Flow & Asthma Meter - Expiratory Flow Pef and Fev1 Measurement - Image 1](https://m.media-amazon.com/images/I/71VoA9MCGLL.jpg) ## Questions & Answers **Q: Does the free downloadable software work on a Mac?** A: It does not work on MAC.
