My research interests include two general areas: Respiratory and Cardiovascular Physiology and Pathophysiology. This includes assessment and management of patients with acute and chronic lung disease, and patients at risk for Perioperative Heart Failure. Intraoperative noninvasive cardiac output studies show cardiac index is the most reliable indicator for hypovolemia during acute surgical anemia, and also for intraoperative heart failure. We have confirmed that a steep alveolar plateau on the capnograph of morbidly obese patients during laparoscopic CO2 insufflation, or during congestive heart failure, is induced by lung volume (FRC) falling below closing capacity towards residual volume. The capnograph slope recovers with increased FRC via positive end-expiratory pressure.
