${session.getAttribute("locale")} 5 Noninvasive cerebrovascular autoregulation assessment in traumatic brain injury: Validation and utility 0.3 indicates impaired CA; in these patients CPP had a significant positive correlation with CBFV, confirming failure of CA, while in those with Mx < 0.3, CPP was not correlated with CBFV, indicating intact CA. These findings were confirmed for Mx-ABP. We found a significant correlation between impaired CA, indicated by Mx-CPP and Mx-ABP, and poor outcome for TBI patients. ABP, CPP, ICP, and CBFV were not correlated with CA but it must be noted that our average CPP was considerably higher than in other studies. This study confirms the validity of this index to demonstrate CA preservation or failure in TBI. This index is also valid if ABP is used instead of CPP, which eliminates the need for invasive ICP measurements for CA assessment. An unfavorable outcome is associated with early CA failure. Further studies using the Mx-ABP will reveal whether CA improves along with patients' clinical improvement.]]> Tue 05 Apr 2016 15:14:45 AEST ]]> Cerebral vasomotor reactivity testing in head injury: The link between pressure and flow Mon 27 Jun 2016 10:02:47 AEST ]]>
