A system for super selective lung lobe isolation and ventilation used to isolate and selectively ventilate lung segments with different compliance.
Diseased lung segments have lower compliance than healthy lung zones, and require more pressure to ventilate. This is the case in several diseases such as acute respiratory distress syndrome (ARDS), pneumonia, lung collapse (atelectasis) and other acute conditions. Use of high pressure can cause overdistention of normal alveoli and cause ventilation induced lung injury (VILI).
The ARDS tube allows segmental isolation, ventilation and specific therapies for diseased lung segments without causing overdistension and lesion of normal lung zones.
