FEV1 forced expiratory volume in the first 1 second of expiration ... spirometry is the FEF25-75, or mid-flow rate. This is a measurement of what flow is like during the middle 1/2 of a forced breath. Although often said to be a measurement of small airways obstruction, the FEF25-75 is fairly non-specific and reductions can be seen with a ...

Wheezes are an expiratory sound caused by forced airflow through collapsed airways. Due to the collapsed or abnormally narrow airway, the velocity of air in the lungs is elevated. [1] Wheezes are continuous high pitched hissing sounds. They are heard more frequently on expiration than on inspiration.

Lack of wheezing suggests that there is partial clearing of bronchospasm in the large airways and there still may be bronchospasm in the small airways. In an acute exacerbation, it is important to continue to treat and monitor the patient after the resolution of wheezing. ... Forced expiratory volume in one second and/or peak flow rate is more ...
