Request for Differentiating Blood Samples from CVAC (central venous) vs. PAC (mixed venous)

[pukekoo]

Hi everyone,

I am seeking a reliable method to determine whether blood samples in the MIMIC database were drawn from a central venous access catheter (CVAC) or a pulmonary artery catheter (PAC). This distinction is crucial for accurately comparing central venous oxygen saturation (ScvO2) with mixed venous oxygen saturation (SvO2).

Request:

If anyone has experience or suggestions for achieving this distinction within the MIMIC database, please share your insights. Specific methods, code snippets, or references to relevant documentation would be greatly appreciated.

Thank you for your assistance!
