Former studies have shown that the application of positive end-expiratory pressure could increase the alveolar fluid clearance rate and decrease the EVLWI.[sup][34],[35]
The respiratory parameters were specified as follows: oxygen concentration was 25%, ventilation frequency was 15 times/min, inspiration and expiration ratio was 1:2, tidal volume was 6 mL/kg, positive end-expiratory pressure was 5 cm [H.sub.2]O, inspiratory oxygen concentration and respiratory rate were adjusted accordingly to maintain the oxygen saturation above 95%, and end-expiratory carbon dioxide concentration was 30-40 mmHg.
Furthermore, inspiratory fraction of oxygen (Fi[O.sub.2]) and positive end-expiratory pressure (PEEP) are adjusted automatically to reach a target pulse oximetry (Sp[O.sub.2]).
Expert opinion in adults suggests avoidance of elevated Fi[O.sub.2] and titration of positive end-expiratory pressure (PEEP) to optimise compliance and oxygenation (10).
Positive end-expiratory pressure (PEEP) was not reduced initially to avoid atelectasis due to the reduced tidal volume.

Spontaneous breathing requires no large transpulmonary pressure swings (high transpulmonary pressure) documented with an oesophageal catheter to achieve acceptable end-inspiratory transpulmonary pressure (<28 cm [H.sub.2]O in spontanously breathing healthy volunteers (63); <25 cm [H.sub.2]O in ARDS patients under CMV (61, 62)) with end-expiratory pressure added as necessary (62).
HFNC is an open ventilation system, yet it is still able to increase end-expiratory pressure. Pharyngeal pressure is affected by mouth-opening or closing, delivered flow, and size of nasal prongs.

IPV combines conventional positive pressure ventilation, high frequency oscillation, and external positive end-expiratory pressure (Antonaglia et al 2006, Fig.
Background: Stress index at post-recruitment maneuvers could be a method of positive end-expiratory pressure (PEEP) titration in acute respiratory distress syndrome (ARDS) patients.
