Table 2. Summary of the critical elements of a thrombelastography ³⁸ .

Phase of Coagulation	TEG Parameter	Normal Range	Description	Interpretation in a Hypocoagulable Patients
Activation	R time	5-10 minutes	Time period from the start of the test until the initial clot formation	If R time >10 minutes, consider: FFP, prothrombin complex, anticoagulant reversal
Amplification	K time	1-3 minutes	Time from beginning of clot formation to reaching a certain strength, specifically an amplitude of 20mm	If K time >3 minutes, consider: Fibrinogen concentrate or cryoprecipitate
Propagation	α angle	53.0-70.0mm	Angle between R and the imaginary line from the initial clot formation to the point of maximum strength related to the K time	If α angle <53mm, consider: Fibrinogen concentrate or cryoprecipitate
Termination	MA angle	50-70mm	Highest point on the curve that represents the maximum clot strength	Si MA <50mm, consider: Platelets
Fibrinolysis	LY30	0-3%	Percentage of reduction in amplitude 30 minutes after the MA	If LY30 >3%, consider: Tranexamic acid
