Bronchoalveolar lavage (BAL) is a useful tool for the diagnostic evaluation and management of patients with pulmonary infection, interstitial lung disease, or malignancy. There exist concern about performing BAL in mechanically ventilated and hypoxemic patients that is associated with the loss of lung aeration and increase in shunt caused by the the procedure and resulting in impaired oxygenation. The impact of BAL on regional ventilation and aeration has not been fully investigated because of lack of monitoring tool. Electrical impedance tomography (EIT) is a promising non-invasive, radiation-free monitoring tool that can evaluate lung volume and efficient ventilation at the bedside in a real-time.The aim of study is to investigate the change in end-expiratory lung volume and ventilation as well as lung mechanics during BAL.
