CRT
Rapid initiation
Citrated Rapid TEG — tissue factor plus kaolin activation. Fastest channel to results in active hemorrhage; CRT.MA gives an early read on clot strength when waiting on conventional labs costs blood.

About
Clinician first.
Curious always.
I am a Doctor of Nursing Practice candidate in nurse anesthesiology at the University of Arizona, with clinical rotations across Phoenix’s Level I trauma centers — Banner University, Banner Desert, and Valleywise — covering general, trauma, and neurosurgery, regional anesthesia, obstetrics, pediatrics, and burns.
Before training, I spent two years in the Trauma / Surgical ICU at Renown in Reno, caring for high-acuity patients drawn from over 80,000 square miles of catchment. That ground — complex resuscitation, vasoactive titration, invasive monitoring — shapes how I think at the head of the bed today.
My clinical and scholarly focus sits at the intersection of trauma anesthesiology and viscoelastic coagulation testing — specifically TEG 6s with the Global Hemostasis with Lysis cartridge — to drive goal-directed resuscitation when minutes and products both matter.

Clinical & Research Focus
TEG 6s in trauma.
A bedside language for hemorrhage.
The Global Hemostasis with Lysis cartridge runs three assays in parallel — CK, CRT, and CFF — producing a profile of clot initiation, clot strength, fibrinogen contribution, and fibrinolysis from a single citrated sample. In trauma, that distinction reshapes the resuscitation.
Hover a parameter below to highlight its channel on the tracing.
CK
R time & MA
Citrated Kaolin — the workhorse channel. CK.R reflects clot initiation and points us toward plasma rather than reflexive platelet transfusion; CK.MA is the integrated read on overall clot strength.
CFF
FFMA — fibrinogen
Citrated Functional Fibrinogen — platelets are inhibited so the MA reflects fibrinogen alone. FFMA reframes cryoprecipitate or concentrate as a goal-directed decision rather than empiric replacement.
LY30
Hyperfibrinolysis
Catching trauma-induced hyperfibrinolysis early changes mortality. CK.LY30 operationalizes the TXA decision in real time — a small number with outsized weight for the patient on the table.
“Goal-directed resuscitation is not just about giving less product. It is about giving the right product at the right moment — and being able to explain why at the end of the case.”
