Dynamic Autoregulation is Impaired in Circulatory Shock.

Background: Circulatory shock is a life-threatening disorder that is associated with high mortality, with a state of systemic and tissue hypoperfusion that can lead to organ failure, including the brain, where altered mental state is often observed. We hypothesized that cerebral autoregulation (CA) is impaired in patients with circulatory shock.

Methods: Adult patients with circulatory shock and healthy controls were included.
