Klinisk og eksperimentell kardiovaskulær overvåkning

Gruppen har som mål å utvikle og teste ny teknologi for, kardiovaskulær overvåkning, kardiovaskulær respons på nye kardiovaskulære terapier og myokardfunksjon i terapeutisk hypotermi og alvorlig sepsis.

Beskrivelse av forskningsprofil

Main aims:

  • Develop and test new technologies in cardiovascular monitoring

  • Cardiovascular response to new cardiovascular therapies

  • Myocardial function in therapeutic hypothermia and severe sepsis

This includes evaluating hemodynamic responses of 

  1. new cardiovascular image guided procedures

  2. ECMO strategies

  3. treatment for end stage heart failure with ventricular assist devices (VAD)

Langsiktig mål

To translate new concepts in technology and physiology into clinical practice.
