Correction to: Neurocrit Care https://doi.org/10.1007/s12028-018-0540-x

The authors note that the number 14 was inadvertently omitted from the formula listed on page 5 of the article. It currently reads

$$ {\text{CPPe}} = {\text{MAP}}*\left( {{\text{EDV}}/{\text{TAPV}}} \right) $$

The correct formula is

$$ {\text{CPPe}} = {\text{MAP}}*\left( {{\text{EDV}}/{\text{TAPV}}} \right) + 14 $$

The number 14 was inadvertently cut out and the oversight was not noticed during the review or the proof process.

The authors would also like to add a reference:
