guys, i read in kaplan that Peak flow is decreased in restrictive lung disease but UW mention there s an increase in expiratory flow rate due to increase in radial traction on the conducting airways.

What do you think?

Thank u for helping.

In restrictive diseases, the lung volumes and flow are reduced but the flow in relation to lung volume is actually higher than normal, in other words there is a supernormal expiratory flows when corrected for lung volume.
