From: Doppler images of intra-pulmonary shunt within atelectasis in anesthetized children
Color Doppler images of intra-pulmonary shunt. The images belong to two mechanically ventilated anesthetized children: (1) 1 year old and (2) 2 months old. a Atelectasis is observed as subpleural consolidations with air bronchograms and coalescent B-lines. b Color Doppler revealed lung vessels within the atelectasis showing a radial distribution to the lung periphery. c Normal lung tissue after successful treatment of the atelectasis by a recruitment maneuver, the normal aeration prevents the pulmonary vessels from being seen by lung sonography.
