Date: 2009 (data collection)
Brief Description: EIT data were collected at Children's Hospital Boston in 2009 during a stepwise lung recruitment manoeuver and positive end-expiratory pressure (PEEP) titration of a patient with the acute respiratory distress syndrome as part of a clinical study (ClinicalTrials.gov identifier NCT00830284). Directory structure is used by the accompanying software to recognize study codes, subject numbers, study dates, and EIT hardware. Filenames end with 'b' for baseline, 'c1'-'c4' for lung recruitment, and 'd1-d5' for PEEP titration.

Data were published in the following two papers:

Format: Data were acquired with the Goe-MF II (CareFusion, San Diego, CA) EIT system, using 16 electrodes with adjacent current stimulation and measurement. Electrodes were placed equidistantly around the thorax at the level of the parasternal 6th intercostal space. Electrode #1 was placed on the sternum and subsequent electrodes (#2, #3, ...) were placed sequentially starting to the patient left of electrode #1.
Methods: Detailed methods are described in the referenced papers. The following figure illustrates the experimental protocol. (Source: C Gómez-Laberge, et al, 2012)

The patient details are as follows: Gender: F, Age: 5.9 years, Weight: 20kg, Condition: Primary ARDS triggered by parainfluenza pneumonia.
