INDEXING OF HEMODYNAMIC PARAMETERS CONSIDERING THE INDIVIDUAL CONTEXT

INDEXING OF HEMODYNAMIC PARAMETERS CONSIDERING THE INDIVIDUAL CONTEXT

CHALLENGE

Hemodynamics is the fluid dynamics of blood flow. It includes a multitude of parameters which characterize and quantify the blood supply of an organism. In the clinical context he- modynamic monitoring is supplied to patients in emergency medicine, intensive care and postoperative areas. The circulation of blood is monitored in order to determine the need of stabilizing measures, such as the administration of medication or the supply of fluids to pre- vent dehydration. Therefor different parameters such as stroke volume variation, intratho- racic blood volume, global end-diastolic volume or the cardiac output are determined. Wor- ld-wide an extended hemodynamic monitoring is performed on more than 500.000 patients.

INNOVATION

The invention describes a procedure for a novel indexation of hemodynamic and biochemical parameters that respect additional contexts. Hemodynamic parameters are often measured as raw values which can have a different meaning for different patients. To increase compa- rability between patients several biometric parameters such as height, body surface, weight and age are used. Typically raw values are divided by single biometric values or a combinati- on thereof (such as body surface area).

However, the indexations remain unspecific, leading to possible cover-ups or even feigning of relations. Also several other important influences are not considered yet in the indexa- tions. This leads to unnecessary difficulties in the conclusive assessment of patient health status. For example different “normal ranges” of the parameters are given nowadays. The procedure according to the invention is based on an extensive patient database and allows for a better indexation. Parameters such as stroke volume variation, central venous pressure, cardiac output, global end-diastolic volume and extravascular lung water are new and better indexed.

COMMERCIAL OPPORTUNITIES

  • Target audience: Producers of medical equipment for intensive care monitoring
  • Applications: Better assessment of patient health status and an easily accesible presentation
  • The benificial assessment of the vital parameters helps to avoid misinterpretation of patient health status by taking formerly unused influences into account

DEVELOPMENT STATUS

Ready for implementation
