Medical technology for intensive care units

Ongoing project. Development of a novel analysis monitor for real-time monitoring of cerebral autoregulation and intracranial compliance in patients in the neurointensive care unit.

 

Background

The SPARC (Science – Powered – AutoRegulation and Compliance) monitor is intended to monitor cerebral autoregulation and intracranial compliance in patients being treated in a neurological/neurosurgical intensive care unit.

Cerebral autoregulation as a physiological regulatory mechanism describes the brain’s ability to maintain constant cerebral blood flow with variable arterial blood pressure values. This ensures that the tissue is constantly supplied with sufficient oxygen and nutrients. Intracranial compliance is the ability of the brain to compensate for volume changes in the intracranial space, for example caused by swelling of the tissue.

Both a disruption of cerebral autoregulation and a severe restriction of intracranial compliance, which frequently occurs in severe traumatic brain injury and spontaneous intracranial haemorrhage, can lead to a variety of complications, such as brain damage due to oxygen deficiency or an increase in intracranial pressure (ICP). Continuous, bed-side monitoring of both cerebral control mechanisms makes it possible to recognise such complications at an early stage and initiate suitable therapeutic measures.

 

Task

The aim of this project is to develop an analysis monitor that allows a valid statement to be made about the state of cerebral autoregulation and intracranial compliance by correlation analysis of intracranial pressure (ICP), arterial blood pressure (ABP) and partial pressure of oxygen (pO2).

For this purpose, the dependencies of the oxygen partial pressure under physiological and pathophysiological conditions are investigated and integrated into a mathematical simulation model. Through simulation analyses, correlation patterns between the ICP, the ABP and the pO2 are investigated and defined when simulating different pathophysiological conditions. Based on the simulation results, a corresponding analysis algorithm will then be developed, which will be part of a new type of analysis software.

This will obtain the measurement data from the intensive care monitors and make the results available to the intensive care physician in real time in the form of a holistic, interpretative graphical representation in a suitable form. The aim is to improve the treatment results for these serious illnesses.

 

Challenge for ASTRUM IT

ASTRUM IT acts as the central project coordinator and is responsible for overall project management. As a certified supplier for medical products, ASTRUM IT is also taking on the role of software development partner.

As part of this partnership, ASTRUM IT is developing the entire software architecture for the innovative analysis monitor. Based on the preliminary clinical work, ASTRUM IT is responsible for developing the algorithms and customising the interfaces.
