The Difference Between Slow and Forced Vital Capacity Increases With Increasing Body Mass Index: A Paradoxical Difference in Low and Normal Body Mass Indices
2014
Respiratory care
BACKGROUND: Obesity reduces FVC, the most commonly used measurement of vital capacity (VC) and slow VC (SVC). It is unknown whether the difference between SVC and FVC is constant in different body mass indices (BMIs). We hypothesized that the difference between SVC and FVC increases as a function of BMI. METHODS: We retrospectively reviewed pulmonary function tests (PFTs) that included spirometry and plethysmography and were performed in adults from January 2013 to August 2013. A total of 1,805
