Influence of isoflurane on hypoxic pulmonary vasoconstriction in dogs.

abstract：BACKGROUND:The medical, social, and economic effects of the teaching mission on delivery of care at an academic medical center (AMC) are not fully understood. When a free-standing private practice ambulatory clinic with no teaching mission was merged into an AMC, a natural experiment was created. The authors compared p...
