High frequency oscillatory ventilation is a form of artificial ventilation where the tidal volume is less than the anatomical dead space. The efficacy of gas exchange depends upon the oscillatory frequency, volume, bias flow and the airway pressure. The present study was undertaken to determine the influence of oscillatory frequency, oscillatory volume and(More)
Thirty-nine epileptic patients underwent pulmonary function testing. Twenty-one of these patients, ranging in age from 16 to 44 years, had taken diphenylhydantoin (DPH) for 2 to 17 years. Eighteen patients, who had taken other anticonvulsants for similar time periods served as controls. Five patients in the DPH group had lung volume abnormalities, four had(More)
