Special function tests

 

CO2-reactivity

The amount of blood supplied to the brain is regulated by altering the resistance of the arterioles in the brain.

  • Estimate of the haemodynamic significance of stenoses of the carotid artery
  • Asymptomatic extracranial stenoses
  • Pre-operative carotid endarterectomy
  • Symptomatic regulation disorders

Non-invasive determination of cerebral autoregulation may be useful in developing strategies for improvement. It may also help to control intracranial pressure (ICP) and maintain optimal cerebral blood flow.

 

Autoregulation test

With the aid of the autoregulation test one can establish whether a constant cerebral blood flow can be maintained even if cerebral perfusion pressure varies.

  • High intracranial pressure – neurotrauma
  • Neurological deficits
  • Deficits in the autonomic nervous system
  • Infant respiration
  • Preoperative investigation prior to cardiac or vascular surgery
     

Evoke Flow Test

This test enables cerebral vascular regulation which is affected by metabolic brain activity (MBA), to be evaluated.

  • Neuroregulation
  • Enables an accurate assessment if autoregulation disorders are suspected e.g. due to occlusion of the proximal basilar, vertebral and cerebral arteries
  • Preoperative function tests
