 Diminished elastic recoil and the collapse of supporting tissues around the airways cause a significant increase in residual volume (RV). However, total lung capacity (TLC) remains unchanged because the decreased chest wall compliance counterbalances increases in lung compliance.

 In obstructive disease, the flow-volume loop begins and ends at abnormally high lung volumes, and the expiratory flow is lower than normal. In addition, the downslope of expiration “scallops” or “bows” inward. This scalloping indicates that at any given lung volume, flow is less. Thus, airway resistance is elevated (obstructive).

 In restrictive disease, the flow-volume loop begins and ends at unusually low lung volumes. Peak flow is less, because overall volume is less. However, when expiratory flow is compared at specific lung volumes, the flow in restrictive disease is somewhat greater than normal.

[q] Although resistance within the trachea and mainstem bronchi is relatively high, it reaches the maximum in ………… because of highly turbulent airflow.
