Lung volumes and compliance in myasthenia gravis and reversible airway obstruction.


A patient with myasthenia gravis, reversible airway obstruction, and a vertical chest wall pressure-volume curve was shown to inflate his lungs to 12 liter during the night. During the day, either spontaneously or after isoproterenol, his functional residual capacity decreased by more than 2 liter. The large lung volume changes occurred without a change in… (More)
