In-vivo airway compliance analysis of acute chlorine gas inhalation injury in rabbit model

In this work, we demonstrate the ability to image and quantify airway changes, we were able to quantify a decrease in airway compliance. The proposed approach will enable further investigations of using OCT assessing pulmonary injury to prevent/treat ARDS using a chlorine inhalation injury model, as well as diagnosing of large airway injury and compliance change due to airway toxic chemical exposure. With enhanced portability over conventional bronchoscopy, we believe our system is capable of field hospital deployment and investigating airway conditions in warfighters. Combining OCT and pressure transducer with bronchoscopy would enhance assessment and treatment of large airway chemical injury.
