The objective of this study was to prospectively determine the utility of resting measurements of VD and VD/VT in predicting PPC in patients who underwent robotic-assisted lung resection for suspected or biopsy-proven lung malignancy. Resting physiologic dead space (VD), and physiologic dead space to tidal volume ratio (VD/VT), may be a better predictor of PPC than PETCO 2. ![]() However, breath-breath breathing pattern significantly affects PETCO 2. Recently, resting end-tidal partial pressure of carbon dioxide (PETCO 2) has been shown as a good predictor for increased risk of PPC. Cardiopulmonary exercise testing (CPET) is performed to predict risk of PPC in patients with severely reduced predicted postoperative forced expiratory volume in one second (FEV1) and diffusion of carbon monoxide (DLCO). Lung resection surgery carries significant risks of postoperative pulmonary complications (PPC). 3The Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center, Torrance, CA, United States.2Department of Medicine, Division of Pulmonary and Critical Care Medicine, VA Long Beach Healthcare System, Long Beach, CA, United States.1Department of Medicine, Division of Pulmonary and Critical Care Medicine, University of California, Irvine, CA, United States.Church 1 Amir Abolhoda 1,2 Janos Porszasz 3 Catherine S. ![]()
