May not improve oxygenation post-abdominal surgery despite V/Q gains; hypothesis-generating and needs randomized confirmation before practice change.
Does changing from supine to sitting position improve gas exchange and ventilation-perfusion distribution in patients after abdominal surgery?
In post-abdominal surgery patients, changing from supine to sitting position improves ventilation-perfusion distribution in low VA/Q regions but does not significantly change PaO2, likely due to a simultaneous decrease in cardiac output.
Bonnet et al. (1988) studied this question.
