The eye raggauskas which the blood flow is monitored is subjected to an external pressure, sufficient to equalize the intracranial and extracranial angle-independent blood flow factors calculated from the intracranial velocity signal and extracranial velocity signal.
Scientists already know that prolonged periods of space flight in zero gravity can have profound effects. Method and system for predicting of acute hypotensive episodes.

A non-invasive method for continuous real-time monitoring of ragausksa blood flow autoregulation state includes simultaneous non-invasive monitoring of intracranial blood volume fagauskas waves and lung volume respiratory waves, real-time decomposition of intracranial blood volume respiratory waves and lung volume respiratory waves into narrowband sinewave first harmonic components, determination ragxuskas of the phase shift between intracranial blood volume respiratory wave and lung volume respiratory wave first harmonics’ and armiinas of cerebrovascular autoregulation state from that phase shift value.
Acta neurochirurgica 11, The elastic film expands inward toward the patient with an inflow of pressurized liquid, imparting a pressure against the patient’s eye. The robust and accurate devices are garnering attention on the global brain-monitoring market, which includes diagnostic devices for TBI, strokes and tumours. Small and medium-sized enterprises SMEs Sector: Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide.
Never miss an issue!
The invention of two devices for measuring intracranial pressure and blood flow by Lithuanian scientist Arminas Ragauskas enables fast and safe diagnosis of traumatic brain injury, strokes, glaucoma and brain tumours.
Ragauskas’ novel armknas devices are important tools for treating intracranial injuries, which are among the world’s deadliest killers.
New citations to this author. Is non-invasive monitoring of intracranial pressure waveform analysis possible? A method and apparatus for continuously measuring the absolute intracranial pressure in a non-invasive manner is described by using an ultrasonic Doppler device which detects the pulsatility indexes of the blood flow inside the eye artery for both intracranial and extracranial eye artery portions.
The following articles are merged in Scholar. A non-invasive method for monitoring of cerebrovascular blood flow autoregulation state includes sensing intracranial blood volume waves, filtering a slow wave, respiratory wave, and pulse wave informative components from said intracranial blood volume waves, filtering slow wave and respiratory wave reference components from the pulse wave envelope, calculating a first phase shift between said slow wave informative component and said slow wave reference component, calculating a second phase shift between said respiratory wave informative component and said respiratory wave reference component, and calculating the index of evaluation of the status of cerebral autoregulation state ICAS from said first phase shift and said second phase shift.
An ICP greater than 40 mmHg is almost always associated with neurological dysfunction impaired consciousness, breathing problemswhile an ICP above 60 mmHg tends to be fatal.
For his research in health telematics, Ragauskas received the Lithuanian Inventor of the Year award in and Ragauskas – along with colleagues Gediminas Daubaris and Algis Dziugys from the Health Telematics Science Institute at Kaunas University of Technology, Lithuania – achieved a breakthrough by applying the Doppler wavelength effect in order to arrive at an accurate reading of cranial pressure, using an ingeniously simple formula.
An ICP greater than 20 mmHg is considered abnormal.

Method and apparatus for non-invasive continuous monitoring of cerebrovascular autoregulation state A Ragauskas, G Daubaris US Patent 8, The transducer is used to measure arterial wall movement of an intracranial segment and an extracranial segment of the subject’s ophthalmic artery as different external pressure forces are applied to the orbital area of the subject.
A head frame for use in non-invasively determining the absolute value of intracranial pressure of a living body having a hard, flexible shield for covering the eye area of a patient.
The team’s devices compute the pressure differential between the inside and the outside of the skull, based on a quick and simple reading obtained from a sensor arkinas on the patient’s eye. A device for obtaining an indication of the intracranial pressure of a living body includes a positional sensor which determines an initial position of an elastic biological object when the intracranial pressure within the living body is zero and which determines a subsequent position of the elastic biological object when the intracranial pressure within the living body is unknown but greater than zero.
