Retrospective analysis of the hemodynamic consequences of prehospital supplemental oxygen in acute stroke

摘要

Objective: Hyperoxia, the delivery of high levels of supplemental oxygen (sO(2)) despite normoxia, may increase cerebral oxygenation to penumbral tissue and improve stroke outcomes. However, it may also alter peripheral hemodynamic profiles with potential negative effects on cerebral blood flow (CBF). This study examines the hemodynamic consequences of prehospital sO(2) in stroke.
