Pulmonary, Critical Care, Hyperbaric and Sleep Medicine


The Division of Pulmonary, Critical Care, Hyperbaric and Sleep Medicine includes over 25 faculty and 100 staff members, providing comprehensive therapy for lung diseases, critical illnesses, and sleep disorders to thousands of adult patients each year in the Inland Empire of Southern California. We have academic and clinical activities at three hospitals, Loma Linda University Medical Center, VA Loma Linda Healthcare System, and Riverside University Medical Center (formerly known as Riverside County Regional Medical Center).

Our services span the spectrum of prevention, diagnosis and treatment of complex pulmonary diseases, critical care and sleep disorders for adults. Subspecialty expertise includes hyperbaric medicine, pulmonary hypertension, asthma and obstructive lung disorders, interventional pulmonology, sleep apnea, and critical illness.

Faculty have research or academic interests in high altitude medicine, asthma, chronic obstructive pulmonary disease, ultrasound-guided bronchoscopy, critical care ultrasound, sedation management, pulmonary hypertension, sleep disorders, hyperbaric medicine, sepsis, hemodynamic monitoring, biomarkers, applied statistics, ethics and humanities in medicine.

Our training program matriculates two fellows per year in the 3-year pulmonary and critical care fellowship. Occasionally, we offer training to exceptional emergency medicine graduates for a 2-year critical care fellowship. Our first fellows, James Dexter, M.D. and Edwin Sammer, M.D., began in 1978, completing their fellowship in 1980. Since then, we have graduated numerous pulmonologists and intensivists, with successful careers in both community and academic settings throughout the country.

Our vision is for a thriving academic division with diverse and exceptional faculty committed to advancing patient care, training and research in respiratory diseases and critical illness that exceeds the rapidly changing needs of today’s healthcare, and upholding the mission of the Loma Linda University Health.

We welcome you to visit our home in beautiful Southern California.
