Vitalograph Pneumotrac Used in Research into the Association of Lower Lung Function with Cessation of Menstruation

Pneumotrac with spirotrac Screen

Vitalograph Pneumotrac was used to conduct spirometry on 141,076 women from the UK Biobank as part of a study that revealed an association between lower lung function and the natural and surgical cessation of menstruation. Pneumotrac has been the spirometer of choice for many medical researchers over the years due its outstanding accuracy and reproducibility.
