"After full insertion of the device, typically to an empiric depth of 50 cm, a chest radiograph should demonstrate the tube descent along the expected course of the oesophagus with the distal tip terminating below the level of the left hemidiaphragm 7. Partial inflation of the gastric balloon (typically performed with 50 mL of air) should subsequently demonstrate the appearance of a lucent, circular structure below the diaphragm and corresponding to the expected location of the gastric body; a supradiaphragmatic location or migration of this lucency is concerning for intrathoracic (oesophageal) malposition."
"When visualised in its long axis, the device will appear as paired, parallel hyperechoic lines. Visualisation of the gastro-oesophageal junction should demonstrate this tubular echogenic traversing it, extending to the gastric body. Dynamic visualisation while advancing the tube may cause agitation of gastric contents; air may be injected into the gastric aspiration port to enhance detection of this phenomenon."
