Lungs Fibrosis and COPD at Lung Volumes!

Can someone explain this concept in words:
> fibrosis patients breath at lower lung volumes AND
> COPD patients breath at higher lung volumes.

after going through costanzo respiratory yesterday, i read through this section, and it made perfect sense. but that was passive reading, and i don't think i really have it sunk in yet.

maybe if someone else could explain it in words, i'll see it from a different perspective.

Thanks!

in patients with stiff lungs (increased elastic resistance), the work of breathing is when the respiratory rate is high and tidal volume is low.
in contrast dz that cause high airflow resistance (eg asthma COPD) slow deep breaths with inc tidal volumes will be favored to minimize the work of breathing.
