Background: Central venous pressure (CVP) monitoring from the peripherally inserted central venous catheter (PICC) has not often been used because of the higher inherent resistance of the PICC due to its longer length and narrower lumen. The objective of this study was to assess the reliability of the CVP measured from PICCs as a predictor of the CVP measured from CICCs in the setting of rapidly fluctuating hemodynamic conditions during liver transplantation.
