In recent years lung recruitment maneuvers (RM) have awakened an increasing interest due to their potential beneficial effects in lung protection so that they have been progressively introduced into clinical practice. Many clinical and experimental studies have described the physiological benefits obtained after lung re-expansion although these benefits are not uniform, partly because of the wide heterogeneity of the RMs applied and lack of criteria defining their goal. Therefore, to date it has been difficult to establish the role of recruitment in the ventilatory management of ARDS patients. However, the information obtained from recent studies has improved our understanding regarding the mechanisms governing lung recruitment, interpretation of its response and its side effects and this has strongly contributed to its improved practical application. Lung recruitment must be applied in a protocolized and individualized way, establishing the pressure necessary to obtain the reasonably possible maximum lung re-expansion in each patient. Post RM PEEP adjustment is an essential aspect which, if ignored, renders RM useless and possibly without indication. Taking these essential aspects into account we are getting closer to, as the author believes, finally demonstrating the benefit of RM in lung protection and ARDS patients' outcome.
