Main finding
As reported in the abstract
- 3 commonly used bedside approaches for assessing cerebral autoregulation (CAR) identified
- CAR impairment common across critical illness (acute brain injury, sepsis, cardiac surgery, hepatic failure); dysregulation can lead to secondary brain injury and worse outcomes
- Techniques vary in invasiveness, continuous monitoring capability and technical requirements
- Methods can help detect impaired CAR, identify optimal perfusion targets, and may guide individualized management
