Drainage times vary, but ideally each Drainage times vary, but ideally each position requires 10 minutes (gumery et al, position requires 10 minutes (gumery et al, 2001).2001).

PositioningPositioning

Positioning restores ventilation to dependent Positioning restores ventilation to dependent lung regions more effectively than PEEP or lung regions more effectively than PEEP or large tidal volumes large tidal volumes (Froese & Bryan, 1974).(Froese & Bryan, 1974).

Positioning has a marked influence on gas Positioning has a marked influence on gas exchange because of unevenly damaged lungs exchange because of unevenly damaged lungs (Tobin, 1994).(Tobin, 1994).

Side lying reduces lung densities in the upper Side lying reduces lung densities in the upper most lung most lung (Brismar, 1985).(Brismar, 1985).

Right side lying may be more beneficial for Right side lying may be more beneficial for cardiac output than left side lying cardiac output than left side lying (Wong, 1998).(Wong, 1998).

Simply turning from supine to side lying can Simply turning from supine to side lying can clear atelectasis from dependent regions clear atelectasis from dependent regions (Brismar, 1985).(Brismar, 1985).
