The new electronic peak flow meter from Microlife, Model PF 100
This is an open, randomised study which compares the Microlife device with an established mechanical device, the MiniWright peak flow meter.
Test persons are patients with asthma bronchiale.
With consent, subjects are randomly assigned a Microlife device or MiniWright device and are instructed how to use it.

Dynamic Testing of peak flow using the 26 flow time wave forms
Dynamic testing was performed by injecting the 26 standard flow time waveforms recommended by the American Thoracic Society using a computer driven spirometry simulator.
Each waveform was delivered into each of two randomly selected peak flow meters five times. For testing, Microife meters were used in the random selection.
