Spirometry Reference Values Mismeasurement for Women

Measurement of lung volume is used routinely by pulmonologists and according to the Global Lung Initiative (GLI) regression, women as a population have different lung volumes than men.  Dr. Philippe Haouzi, medical director of Cleveland Clinic’s Pulmonary Function Testing Lab, discusses the lack of clear evidence for this assumption and why it’s time to re-evaluate the inclusion of sex as a parameter in developing reference values for spirometry.
