Flow-volume loops: clinical correlation.
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.
متن کاملExercise flow-volume loops in prepubescent aerobically trained children.
We studied mechanical ventilatory constraints in 13 aerobically trained (Tr) and 11 untrained (UT) prepubescent children by plotting the exercise flow-volume (F-V) loops within the maximal F-V loop (MFVL) measured at rest. The MFVL allowed to determine forced vital capacity (FVC) and maximal expiratory flows. Expiratory and inspiratory reserve volumes relative to FVC (ERV/FVC and IRV/FVC, respe...
متن کاملValidity of forced expiratory flow volume loops in neonates.
It is claimed that suddenly squeezing a newborn baby's trunk with a pressure of 3-4 kPa produces a flow volume curve that can be used to measure the function of the small airways. If the squeeze is applied during expiration rather than at the end of inspiration, however, anomalous results may be obtained. One possible explanation is that the babies are limiting expiratory flow by making inspira...
