Brief summary
This is a single center prospective observational study to compare QStat parameter measurements in arterial and venous blood samples collected in parallel from patients undergoing liver transplantation.
Detailed description
In this single center prospective observational study, 25 cardiac surgery subjects will enrolled, each with parallel artrial and venous samples collected at 3 time points to yield 75 matched samples for analysis on the Quantra System with the QStat Cartridge.
