What does Rotem measure?

BACKGROUND: ROTEM is a method of measuring hemostasis quality via the viscoelastic properties of a blood clot and is designed for patient blood management. ROTEM provides a rapid assessment of clot development from secondary hemostasis to clot lysis by evaluating clot formation, clot firmness, and clot fibrinolysis.

What does Rotem mean?

The name Rotem is primarily a gender-neutral name of Hebrew origin that means Desert Plant. Unisex name, but most commonly used for females.

Where is Rotem used?

TEG®/ROTEM® tests are relatively rapid to perform (< 30 min) and have traditionally been used as point-of-care tests in surgical departments. Their main advantage is to provide a complete profile of clot formation, including the kinetics of clotting, clot strength, and fibrinolysis.

When is Rotem used?

method for hemostasis testing in whole blood. Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood. It is a modification of traditional thromboelastography (TEG).

What is alpha angle in Rotem?

α-Angle (degrees): The α-angle is the angle tangent to the clotting curve at the 2-mm amplitude point, with a larger angle indicating more rapid clotting, and is typically displayed 30 to 40 seconds after the CT. 7. Normal range for EXTEM α-angle (α- EX) is 65 to 80 degrees.

What is Rotem machine?

Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood. It is a modification of traditional thromboelastography (TEG).

How does TEG Rotem work?

Rotational thromboelastometry (ROTEM) evolved from TEG technology and both devices generate output by transducing changes in the viscoelastic strength of a small sample of clotting blood (300 µl) to which a constant rotational force is applied.

What is the difference between Rotem and TEG?

In fact the main difference between TEG and ROTEM is the bit which rotates (TEG rotates the cup, and ROTEM rotates the pin). Irrespective of which bit is rotating, some impediment to the rotation develops as the blood clots.
