About Andrew Ray


Dr. Ray’s work focuses on respiratory muscle dysfunction and cancer treatment-induced symptomology (dyspnea) and a reduced exercise capacity. More specifically, he uses respiratory muscle training to strengthen the breathing muscles in the lungs before and after surgery and during treatment. This helps minimize complication from surgery as well as common symptoms associated with treatment like fatigue and dyspnea, which might also help reduce the length of time a patient needs to stay in the hospital after treatment. With a home-based approach, Dr. Ray’s work has the potential to reach a large number of patients that may otherwise not receive rehabilitation services.
