title: Flow-volume loops: clinical correlation.
abstract: Flow volume loops are an essential part of spirometry testing. Their appearance can give information that can be helpful in the differential diagnosis of a patient's clinical condition. We present two clinical scenarios in which careful evaluation of the flow-volume loop gives an insight into the cause of the disease process.
