文摘
- •
We investigated the status of cerebral autoregulation (CA) by powerful correlation coefficient analysis method.
- •
Our results demonstrated that CA was impaired following acute intracerebral hemorrhage.
- •
We are the first to applied nonlinear sample entropy algorithm to analyze the variability of cerebral blood flow velocity (CBFV).
- •
The variability of CBFV significantly increased following supratentorial hemorrhage.
