Respiratory failure
Measurement, hypercapnia, and care after hospitalization.
Brian W. Locke, MD, MSCI
Assistant Professor of Research, Intermountain Health
Pulmonary and Critical Care Physician
Advisor, MTN · Adaptive healthcare data integration
I study how health systems recognize, evaluate, and manage respiratory failure, from physiologic measurement through care after hospitalization.
About
My research uses linked clinical and claims data, computable phenotypes, clinical prediction, causal inference, and pragmatic trials to improve the recognition and management of respiratory failure. I practice in the Shock Trauma ICU and Schmidt Chest Clinic and serve as core faculty in the University of Utah Pulmonary and Critical Care Fellowship.
