PositioningPositioning

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

Right side lying may be more beneficial for cardiac Right side lying may be more beneficial for cardiac output than left side lying output than left side lying (Wong, 1998).(Wong, 1998).Simply turning from supine to side lying can clear Simply turning from supine to side lying can clear atelectasis from dependent regions atelectasis from dependent regions ((BrismarBrismar, 1985)., 1985).
