Evaluation of pulmonary B lines by different intensive care physicians using bedside ultrasonography: a reliability study.

Objective: To evaluate the agreement between intensive care physicians with similar training in the use of bedside lung ultrasonography in identifying pulmonary B lines, visualized in real time, to verify the reproducibility of the method.

Methods: A total of 67 patients with some ventilatory deterioration identified within 12 hours after a pulmonary ultrasonography in the period from November 2016 to March 2017 were analyzed, and all were admitted to an intensive care unit of a private hospital in Belo Horizonte, Minas Gerais. The lung ultrasonographies were performed by three different professionals, termed A, B and C, and the time interval between each lung ultrasonography was less than 3 hours.
