Respiratory failure & ventilation
Physiological effects of awake prone position in acute hypoxemic respiratory failure
Authors' conclusion
Prone position improves oxygenation, increases EELI and promotes VT distribution towards dependent lung regions without affecting VT size, ΔPL, lung compliance and pendelluft magnitude. Prone position reduces respiratory rate and increases ΔPES because of positional increases in airway resistance and prolonged expiratory time.
