Product Description

This device is used to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) in both children and adults. PEF is the fastest speed air can be blown out of the lungs after inhalation. FEV1 measures the volume after exhaling in 1-second. Peak Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) measurements can tell how well lungs are breathing by monitoring airflow. Doctors can have patients monitor changes in airflow and record the results. The automatic memory stores and provides easy access to the last 240 readings along with the time and date.

Customer Reviews

easy asthma management
This is my first peak flow meter and it works beautifully. It comes with three mouthpieces and is easy to snap apart and clean. It feels solid and durable. It comes with a large booklet and a carrying case. Best of all, it stores the measurement in memory along with the time and the date it was taken, in case you don't have time to log it right away. It gives an immediate red, yellow, or green indication on each measurement also. The Microlife also measures FEV1, although this seems to vary proportionally to Peak Flow so I don't know what use it has.

1 of 2 did not work
I purchased 2 of these meters. One of the two did not work properly. The readings were over 100 points higher than my mechanical meter. I kept getting a new "HI" reading just about each time I took readings. During an attack, I took my readings, and received a new "HI"(reading over 685). I then used my mechanical meter, and found I was in the red zone (actual reading 370).

The second meter I purchased is for my son, his 'appears' to be working properly. I will monitor this closely. As far as I am concerned, this meter is a piece of garbage.

Nice design
I tried a Pico electronic peak flow meter and it never gave consistent measurements.

The Microlife is a big improvement. It uses a fan/propeller to measure flow, via an
optical sensor. The part you blow through can be removed for cleaning without getting the electronics wet.

The Windows software is so-so. If you aren't running as a user with Administrator privileges, the program pops up an error message.
