WebPURPOSE: To define the effects of obesity on DLCO and DL/VA. METHODS: We retrospectively reviewed our pulmonary function testing (PFT) data for overweight individuals, defined as a body mass index (BMI) of >25, who underwent PFTs. We selected for overweight non-smoking individuals who had a total lung capacity (TLC) > 80% of … WebThe DL CO provides a measure of the severity of parenchymal lung disease—although the measurement probably reflects ventilation-perfusion inequalities rather than impaired function of the alveolar capillary membrane. Reduced DL CO is strongly associated with adverse postoperative outcome. Historically, patients undergoing pulmonary resection ... how do more grain boundaries affect strength
