Thromboelastogram (TEG) Flashcards
1
Q
R time =
A
- Time to begin forming the clot formation
- 6-8 minutes
- Determined by coagulation factors
- Treat with FFP
2
Q
K time
A
- Time until the clot has achieved fixed strength.
- 3-7 minutes
- Fibrinogen
- Give Cryo
3
Q
Alpha angle=
A
- Speed of fibrin accumulation
- 50- 60 degrees
- Fibrinogen problem area
- Give cryo
4
Q
Maximum amplitude (MA)
A
- Measurement of clot strength
- Highest vertical amplitude
- 50-60mm
- Platelet problem area
- Give platelets +/- DDAVP
5
Q
Amplitude at minutes after maximum amplitude (A60) =
A
- Height of vertical amplitude 60 minutes after the maximum amplitude.
- MA -5
- Excess fibrinolysis
- Give TXA
