Our laboratory studies lung mechanics in the context of the acute respiratory distress syndrome (ARDS).  A hallmark of ARDS is pulmonary edema, in which liquid leaks out of the blood vessels into the alveoli, or smallest airspaces, of the lungs.  Such liquid-filling of the alveoli causes breathing difficulty in patients.  For breathing assistance, ARDS patients are placed on mechanical ventilation.  In attempting to provide sufficient assistance, however, mechanical ventilation can cause an additional over-distension injury, ventilator induced lung injury (VILI), and prevent recovery.  The mortality rate for ARDS/VILI exceeds 35%.

To address this problem, we study surface tension in and inflation mechanics of the edematous lungs.  We have developed the first means of determining surface tension in flooded alveoli of the lungs.  With this method, we have shed doubt on the common belief that plasma proteins present in edema liquid raise surface tension in the lungs.  We have further identified novel methods of lowering surface tension in the lungs.  These methods, which should lessen VILI, could be used as new treatments for ARDS.  

In our investigations of lung mechanics, we have used combined experimental and computational methods to determine the Young's modulus of the alveolar septum in situ in the lungs.  Further, we are designing novel mechanical ventilation waveforms targeted at reducing VILI.

Our overall goal is to use our understanding of mechanics to inform development of novel treatment methods for ARDS.
