Abstract:
:This report describes the radiologic appearance of the intravenous oxygenator (IVOX), an intracorporeal CO2-O2 exchanger for use in patients with severe respiratory deficiency, and the extensive radiographic and sonographic support required for its use. Six patients aged 19-39 years who had severe adult respiratory distress syndrome (ARDS) and who were not expected to survive were selected for IVOX placement; ARDS was caused by trauma (four patients), severe pneumonia (one patient), or a fat embolus from a tibial fracture (one patient). Before insertion of the IVOX, all patients underwent evaluation of their right internal jugular vein, right common femoral vein, and inferior vena cava with real-time ultrasound (US) to ascertain vascular size. The IVOX improved oxygenation in all patients; because of such improvement, one patient survived. Use of the IVOX may become common; hence, radiologists should understand how the IVOX functions and its appropriate placement, be able to identify it on chest and abdominal radiographs, and appreciate the importance of US in placement of this device and follow-up.
