Respiratory failure & ventilation
Physiological and clinical effects of trunk inclination adjustment in patients with respiratory failure: a scoping review and narrative synthesis
Authors' conclusion
In patients with acute respiratory failure, transitioning from a supine to a semi-recumbent position leads to decreased respiratory system compliance and increased airway driving pressure.

Main finding
As reported in the abstract
primarily within 60 min post postural change
- Supine to semi-recumbent: decreased respiratory system compliance and increased airway driving pressure
- C-ARDS: improved ventilatory efficiency, lower PaCO2
- Oxygenation improved in a few patients, only those with increased EELV on moving to semi-recumbent
