ROTEM
Carlos Sarta
ROTEM (rotational thromboelastometry) is a point-of-care viscoelastic test that evaluates coagulation in real time using whole blood, rather than just providing an isolated number like PT or aPTT. In just a few minutes, it shows how the clot forms, how firm it is, and whether it degrades, through its channels (EXTEM, INTEM, FIBTEM, APTEM, HEPTEM) and parameters (CT, CFT, A5/A10, MCF, ML). It is a key tool for guiding transfusion therapy in trauma, cardiac surgery, postpartum hemorrhage, and severe perioperative bleeding. The problem: ROTEM provides a lot of information quickly... but interpreting it under pressure, remembering normal ranges, and translating it into a concrete action plan isn't always easy, especially outside clinical areas where it is used daily. That’s where ROTEM Interpreter comes in. Enter the values from the terminal, and the app does the rest: Live temogram: As you type, the clot morphology for each channel is drawn—just as you see it on the device—connecting the numbers with the visual image to cement the pattern in your memory. Automatic interpretation: Identifies key patterns: hyperfibrinolysis, fibrinogen vs. platelet deficiency, factor deficiency, heparin effect, and hypercoagulability. Suggested action with dosing: Translates the findings into practical recommendations, calculating fibrinogen dosage (based on target A5 increase and body weight) and A5-guided platelet dosing. Step-by-step management algorithm: (EXTEM/FIBTEM) featuring zoom and pan capabilities for detailed exploration. Integrated guide: Test portfolio, diagnostic patterns, fibrinogen calculation, and an evidence and guidelines section (Cochrane, European Trauma Guideline, ESAIC, EACTS, NICE, OBS2) with links to the original sources. Device-saved interpretation history: 100% offline, light/dark modes, for both adult and pediatric profiles. Who is this for: Intensivists, anesthesiologists, emergency physicians, hematologists, and residents who want to interpret ROTEM quickly and confidently at the bedside. Decision support tool: This app does not replace clinical judgment or correlation with the patient's context; always verify against local ranges and protocols.
