In patients with restrictive lung disease, the WOB is minimized when the tidal volume is low. Therefore, to compensate for low lung volumes, ☆rapid, shallow breathing is favored (as in this patient).
In contrast, in patients who have obstructive lung disease, the WOB is minimized with lower respiratory rates and higher tidal volumes (ie, relatively slow, deep breathing) (due to faster airflow with increased turbulence)
