Continuous monitoring of lung ventilation can be useful in treating patients admitted to the intensive care unit (ICU). Electrical impedance tomography (EIT) has been used as a relatively new imaging technique for this purpose. We presented a patient with pneumonia who was admitted to the ICU after pulmonary thromboembolism (PTE) required to perform bronchoalveolar lavage (BAL). A drainage procedure and subsequent improvement in pulmonary function were monitored using EIT contributed to the treatment process. The patient has been discharged from the hospital with an improved general condition. (C) 2018 Elsevier Inc. All rights reserved.
