Erratum to: Journal of Clinical Monitoring and Computing 2016 end of year summary: cardiovascular and hemodynamic monitoring (vol 31, pg 5, 2017)

In the original publication of the article, in Sect. 2.2, the sentence that reads as “TPTD is a well-validated … femoral vein)” was incorrectly published. The correct sentence should read “TPTD is a well-validated … femoral artery)”. In Sect. 4, fourth paragraph, the sentence that reads as, “Furthermore, the pleth variability … index (PI)-values, was recorded” should read as “Furthermore, the pleth variability … index (PI)-values divided by the maximal PI was recorded”.
