The Microlife Digital Peak Flow Meter PF100 is a reliable, compact device used to measure Peak Expiratory Flow (PEF) - being the fastest speed that air can be blown out of the lungs after inhalation - and Forced Expiratory Volume in 1-second (FEV1) in both children and adults, which can indicate early warning signs for emerging asthmatic episodes.   According to medical practice guidelines and recommendations, patients with asthma, COPD, emphysema, and other lung diseases need to manage their condition at home or on-the-go during one’s daily routine. The PF100 meets and exceeds these needs, and fits comfortably in a purse, briefcase, or book bag. Used in conjunction with the PC analyzer software (sold separately), this device becomes a powerful instrument for data recording and analysis. Easily e-mail or print graphs/reports for your doctor and eliminate the daily nuisance of handwritten records and diaries.  A built in digital memory function provides easy access to the last 240 readings along with the date and time, and the results are automatically stored after each reading.

Monitoring Peak Flow and FEV1 in between visits to the doctor can be vital to a patient's care. Peak Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) measurements can tell how well lungs are breathing by monitoring a user's airflow, which serves as an important diagnostic tool to help determine whether the patient's treatment regimen is working, or needs revision. .

quite useful equipment Review by B K Roberts
In fact, I was quite surprised at how quickly you shipped my order. Having just completed a full-blown Pulmonary Function Test, the oximeter and peak flow meter are quite useful to compare to my benchmark from the pulmonoligist. There was excellent correlation between the test results from the PFT and your products. (Posted on 6/27/2019)
