The effect of aorta unfolding and remodelling on oesophageal Doppler readings as probe depth is varied J. Zhang, L.A.H. Critchley, L. Huang British Journal of Anaesthesia Volume 115, Issue 5, Pages 708-715 (November 2015) DOI: 10.1093/bja/aev343 Copyright © 2015 The Author(s) Terms and Conditions

Fig 1 The measurements of variables that quantified descending thoracic aortic remodelling on the erect posteroanterior chest radiograph: (a) measurement of lateral displacement; (b) measurement of curvature angle.

Fig 2 Correlations of (a) lateral displacement and (b) curvature angle measured on chest radiograph with a maximum lateral distance of the aorta measured on computed tomography (CT). Data are collected from 32 patients, with 10 from the 70 patients of the present study.

Fig 3 Variability in oesophageal Doppler monitor (ODM) readings over a 10-cm probe depth range as aorta unfolding increased, quantified by the (a) lateral displacement and (b) curvature angle measurements from erect posteroanterior chest radiograph. Regression lines and equations were shown. CV: coefficient of variation; SV: stroke volume.

Fig 4 Receiver operating characteristic (ROC) curves showing the ability of (a) lateral displacement and (b) curvature angle to predict a >10% variation in stroke volume readings of the oesophageal Doppler monitor (ODM) as probe depth varies over a 10-cm range. The optimal cut-off value is shown by the open circle on the ROC curve. British Journal of Anaesthesia 2015 115, 708-715DOI: (10.1093/bja/aev343) Copyright © 2015 The Author(s) Terms and Conditions
