Does anyone know the mechanism behind early mobilization post-op and reduced risk of atelectasis?

Atelectasis=closed airways. Deep breathing opens airways. With activity (or incentive spirometry) comes deeper breathing

-Getting them up out of bed reduces dependent airway collapse (i.e. bases and posterior segments if they are laying down all the time)
-Helps minimize splinting
-as above, increasing activity causes deeper inspiration/less atelectasis.
