New EEG trace interpretation method predicts neurological recovery of cardiac arrest patients

11.05.2009
Miikka Ermes (M.Sc., Eng.), Research Scientist from VTT Technical Research Centre of Finland will publicly defend his doctoral thesis presenting methods for analysing human biosignals on 15 May 2009, including innovative methods for the verification of brain damage following cardiac arrest.
Up until now, the use of electroencephalography (EEG) in the monitoring of cardiac patients has been limited due to interpretation difficulties.

A study conducted by a multi-disciplinary research team showed that variables derived from EEG traces can be used to predict neurological recovery even within the first 24 hours following cardiac arrest.

The researchers derived variables from the EEG trace which simplified the interpretation process. The long-term goal of the team is to develop methods that allow continuous monitoring of neurological recovery at hospitals. This would allow the health care personnel to promptly respond to changes in the patient’s brain status.

If blood circulation stops, the tissue in the patient’s body soon begins to suffer from reduced oxygen delivery. Brain cells are particularly sensitive to oxygen deprivation, which explains why even successfully resuscitated patients often sustain neurological damage. In its mildest form this is manifested as transient memory or movement disturbances; in the most serious cases, they can cause permanent unconsciousness.

Basically, an electroencephalogram (EEG) records the electrical activity of the brain in the same way as an electrocardiogram (ECG) records heart activity. Interpreting EEG traces is more difficult, however, since unlike the electrical activity of a regularly beating heart, the electrical activity of the brain consists of irregular impulses generated by billions of brain cells. While the applicability of EEG in predicting neurological recovery has long been known, difficulties in interpreting the recordings have limited the routine use of EEG in patient monitoring. Interpretation almost invariably requires consulting a specialist, which may cause a delay in treatment.

Miikka Ermes will publicly defend his doctoral thesis “Methods for the Classification of Biosignals Applied to the Detection of Epileptiform Waveforms and to the Recognition of Physical Activity” on Friday, 15 May 2009 starting at 12 noon. The public defence will take place in the Tietotalo Auditorium (room TB219) of the Tampere University of Technology (TUT), address: Korkeakoulunkatu 1, Tampere. Professor Georg Dorffner from the Medical University of Vienna (Austria) will act as the opponent.

The doctoral thesis, which belongs to the field of signal processing, is available on the Internet at

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
