Rotational thromboelastometry variables derived from thromboelstometer graph

ROTEM variable	Description
CT: Clotting time (s)	Time until the recognizable start of clot formation (2 mm amplitude)
CFT: Clot formation time (s)	Time until amplitude of 20 mm is reached. Represents the clot formation dynamics
Angle: Alpha-angle (°)	Angle between central line and a tangent to the curve through the 2 mm amplitude point. Represents the kinetics of clot formation
MCF: Maximum clot firmness (mm)	Maximum firmness (amplitude) that the clot achieves during the measurement
A10-A30: Amplitude at 10-30 min after CT (mm)	Describes the clot firmness at 10-30 min after CT
CL30: Clot lysis index at 30 min after CT (%)	Ratio between the MCF and the amplitude 30-60 min after CT. Describes the progress of fibrinolysis
ML: Maximal clot lysis (%)	Ratio of the lowest amplitude detected after achieving MCF to the MCF
