Philosophy of Care
Integrated, team-based multidisciplinary care is essential for successful treatment of advanced cardiopulmonary disease. Bringing the patient, family, physicians, nurses, and therapists in alignment on a common set of values and goals gives the patient the best care and highest chance of recovery.
Clinical Interests
Dr. Peterfreund is a critical care anesthesiologist offering general anesthesia services with a focus on thoracic and vascular anesthesia. He also serves in the cardiovascular ICU with a focus on temporary circulatory support and point-of-care ultrasound.
Research/Academic Interests
Dr. Peterfreund is interested in teaching about cardiopulmonary physiology and how point-of-care ultrasound allows for the real time understanding of this physiology as a way to target and refine our treatments.
