Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In stable obese subjects, in sitting and supine positions, the investigators measured Borg dyspnea score, static lung volumes, expiratory flow limitation, and single-breath nitrogen expiration test, from which the investigators determined closing volume and closing capacity, slope of phase III, and opening capacity.
Orthopnea was defined as any increase in the Borg score in the supine position from its value in the sitting position
