ROTEM sigma is an easy-to-use, cartridge-based Thromboelastometry System that delivers rapid results at the point of care (POC), providing guidance in bleeding management. Used to assess clinically significant bleeding situations in cardiac surgery and liver transplantation, ROTEM TEMograms provide clear, real-time information, helping clinicians to optimize hemostasis while minimizing blood loss and blood product exposure, key goals of patient blood management programs.
