The maximal recruitment strategy (MRS) is considered an efficient maneuver to reverse nonaerated lung in ARDS patients. There is no information regarding tidal recruitment during MRS.
Early and severe ARDS patients were submitted to MRS guided by thoracic CT: A - recruitment phase (PEEP 10 to 45 cmH2O and constant driving pressure 15 cmH2O); B - PEEP titration phase (PEEP 25 to 10 cmH2O). Images were obtained at end expiration and inspiration. Global and regional quantitative CT analyses from each step of PEEP were compared .
MRS decreased nonaerated areas and tidal recruitment. Increasing PEEP without full recruitment may cause lung injury exacerbation in the severe ARDS population.
