Abstract__ Background In this study we analyzed maximal inspiratory pressure MIP and maximal expiratory pressure MEP values in a stable COPD population compared with normal subjects. We evaluated the possible correlation between functional maximal respiratory static pressures and functional and anthropometric parameters at different stages of COPD. Furthermore we considered the possible correlation between airway obstruction and MIP and MEP values. Subject and methods ll0 patients with stable COPD and 2l age-matched healthy subjects were enrolled in this study. Patients were subdivided according to GOLD guidelines 3l mild 39 moderate and 28 severe. Results Both MIP and MEP were lower in patients with severe airway impairment than in normal subjects.
