[Results of the flow-volume curve in XXXX with bronchial asthma (author's transl)].

@entity748 @entity1 @entity16535
In 65 @entity748 @entity1 aged 18 to 59 years maximal expiratory flow-volume curves were performed. The measurements were done with a pneumotachograph in connection with a self-developed two-channel FM modulator, a stereo tape recorder, and a X-Y recorder. We examined 53 @entity1 in clinical remission and 12 @entity1 during an attack period. The greatest sensitivity of the tested flow-volume data had @entity16535 50/FVC pred. and the time constant of the terminal portion of the curve. @entity16535 50/ @entity16535 75 and V2/V1 were about equally sensitive for detecting ventilatory inhomogeneities. The attack group most differed from the remission groups in FVC % pred., @entity16535 50/FVC pred. and the other flow rates. The flow-volume curve is a valuable method to assess obstruction and ventilatory inhomogeneity in @entity748 @entity1 . It has a greater sensitivity than conventional spirometry.
