Patient Satisfaction Ratings

Patient Rating Breakdown

The Patient Satisfaction Rating is an average of all responses to the care provider related questions shown below from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.

Responses are measured on a scale of 1 to 5 with 5 being the best score.

Comments are submitted by patients and reflect their views and opinions. The comments are not endorsed by and do not necessarily reflect the views of Penn Medicine.

Description of Research Expertise:

Dr. Schwab’s research has focused on the pathogenesis of obstructive sleep apnea utilizing novel upper airway imaging techniques. His studies help elucidate the role of the motion of key structures of the upper airway in mediating airway closure. By examining dynamic state-related changes in the upper airway and soft tissue structures surrounding the upper airway he has begun to understand the biomechanics of apneic events. He has studied patients with both magnetic resonance imaging and electronic beam computed tomography during wakefulness and sleep. Several novel findings have resulted from these studies: 1) the anatomic significance of the lateral pharyngeal walls in mediating airway caliber in normals and apneics; and 2) the characterization of the changes in upper airway caliber during the respiratory cycle and the importance of end-expiratory airway narrowing. Dr. Schwab collaborates closely with members of the Departments of Radiology and Biomechanical and Computer Engineering. They have developed state-of-the-art, computer graphics-based analysis software to help model in three dimensions the biomechanical interrelationships between the soft tissue structures and the upper airway.
