This measurement is useful in detecting changes in airways that could signal a worsening of symptoms or an improvement in breathing function for people with respiratory conditions such as Asthma and emphysema. This device is packaged and labeled so it can be used as a screening device in a hospital or other clinical setting. Labeling is also included for the use of the device if dispensed by a health care provider to a patient for personal use.
