Pulmonary function testing measures how well you are breathing.
It is important to realise that there is no time axis on the flow-volume loop so one can not interpret time intervals.
In this article, we'll focus on helping you to understand what the results of your spirometry test mean.
Spirometry is also used to monitor the severity of some other lung conditions and their response to treatment.
