ABSTRACTIn the acute respiratory distress syndrome (ARDS) mechanical ventilation remains the main method to implement recruitment maneuvers and positive end expiratory pressure (PEEP) and delivering oxygen and eliminating carbon dioxide. Considering the clinical importance of mechanical ventilation based on the open-lung strategy, special attention should be paid to assessement of the degree of lung aereation. Ultrasound (US) is widely applied for the diagnosis in Intensive Care Unit. US exam may also be useful for evaluation of lungs and diagnosis of their dysfunction. In patient with ARDS inflammation and loss of lung volume induce collapse and atelectatic areas in special in dependent zones. US is a useful tool to the bedside to evaluate the increase in lung volume and decreased areas of alveolar collapse during recruitment maneuvers and PEEP. The aim of this paper is to review current concepts related to the ultrasonographic assessement of alveolar recruitment maneuvers and PEEP.
