What does TEG measure?
Clot strength over time
What does R measure on a TEG?

If LY30 is high on a TEG, the patient is in what kind coagulation state?
Hypocoagulable state or hyperfibrinolysis
How can an elevated R parameter on a TEG be corrected?
Give FFP to increase clotting factors
How can a low MA CFF parameter on a TEG be corrected?
Give cryo to increase fibrinogen
How can a low MA CRT parameter on a TEG be corrected?
Give platelets to increase overall platelet activity
How can an elevated LY30 parameter on a TEG be corrected?
Give TXA/Amicar to counter the hyperfibrinolysis
What must the ACT be before turning on suckers and vents?
300 seconds
What is the minimum ACT to initiate bypass? What is the ideal ACT?
400, 480
What is one reason why ACT devices can be unreliable?

What can be used to standardize the variance seen in ACT devices?
INR
What is different about the ACT test vs. the INR, PT, and PTT?
The ACT uses whole blood, the others used centrifuged blood
