Specifically this type of loop shows an abrupt decrease in flow rate.

. One of the more recognizable flow-volume loop contours is the one associated with severe airway obstruction. Modem microprocessor controlled recording spirometers. Flow volume loop revealed a normal upstroke to the peak flow and then a rapid linear fall to an inflection point at approximately 43 percent of forced vital capacity. Low maximum forced expiratory flow biphasic expiratory curve flow oscillations and notching.

Flow Volume Loops are more sensitive and informative in detecting pulmonary diseases than conventional spirometry. Take the maximum deep breath in then. Flow-volume loops in restrictive lung disease If the restrictive disease did nothing but reduce the volume of the lung the curve would look rather normal but diminished in size. On this same axis exhalation is found in the area above the x.
