All eyes are now on NASA’s Scott and Mark Kelly, the only twins ever tested for the effects of long-duration space travel on the human body. 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 placed on the patient’s eye. How it works The invented device gauges brain pressure through a sensor placed safely and painlessly on the patient’s eye, to which, in much the same way as the inflated armband used to measure blood pressure, it applies a small amount of pressure at the same level as that of the ophthalmic artery just behind the eye and leading to the brain.
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.
Their combined citations are counted only for the first article.

Marketed by the inventor’s start-up company Vittamed as non-invasive intracranial pressure meter Vittamed and non-invasive cerebral auto-regulation monitor Vittamedthe devices received CE marking approval in The biomarkers can then be used to generate an acute hypotension prediction classifier, or monitored factor, derived from a three dimensional temporal representation of two or more biomarkers.
Method and apparatus for non-invasive continuous monitoring of cerebrovascular autoregulation state. In Europe, roughly 2. Method and apparatus for non-invasively deriving and indicating of dynamic characteristics of the human and animal intracranial media A Ragauskas, G Daubaris US Patent 5, ragaiskas, Unlike many other diagnostic tools used in neurology, they need not be calibrated for individual patients and provide neurosurgeons, neurologists and ophthalmologists with a fast, accurate and above all safe means of diagnosing a wide range of neurological conditions and glaucoma.

Ragauskas developed an interest in measurement sciences as a young scientist and established the Telematics Science Laboratory at Kaunas University of Technology in to further his research. The eye in 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.
Arminas Ragauskas with a brain-wave monitor Arminas Ragauskas Arminas Ragauskas using an ultrasound device Device for measuring intracranial pressure and blood flow Monitoring a patient’s brain pressure Ultrasound sensor for brain pressure. A method raagauskas apparatus for continuously measuring the absolute intracranial pressure in a non-invasive manner is described by using an ultrasonic Doppler device which arminass the pulsatility indexes of the blood flow inside the eye artery for both intracranial and extracranial eye artery portions.

Data derived from sensors or other measurement devices such as ECG sensors can be used to generate biomarkers. The eye in which the blood flow is monitored is subjected to a small pressure, sufficient to equalize the pulsatility armibas measurements of the internal and external portions of the eye artery.

Amrinas heart, for instance, tends to become more spherical and lose muscle mass due to the lack of gravity, which can cause problems on return to Earth.

The robust and accurate devices are garnering attention on the global brain-monitoring market, which includes diagnostic devices for TBI, strokes and tumours.
For his research in health telematics, Ragauskas received the Armnas Inventor of the Year award in and All eyes are now on NASA’s Scott ragausmas Mark Kelly, the only twins ever tested for the effects of long-duration space travel on the human body.
Brought to market intwo medical devices developed by Ragauskas and a team of fellow Lithuanian scientists give neurologists and other doctors precious extra time to detect and assess increased cranial pressure.
A method and system of predicting a hypotensive episode in a patient using one or more time varying hypotension specific biomarkers corresponding to physiological processes in rwgauskas patient.
When the monitored factor exceeds a predetermined threshold the method and system trigger an alarm before an appearance of a hypotensive episode in the patient. Patent information events Consult our calendar.
The elastic film expands inward toward the patient with an inflow of pressurized liquid, imparting a pressure against the patient’s eye.
Apparatus and method for simulating arterial arjinas flow under various pressure conditions. Arminas Ragauskas, Gediminas Daubaris.
The use of hyperventilation therapy after traumatic brain injury in Europe: The inventor’s measuring devices are currently being used by the US National Space Biomedical Research Institute at a facility run by the German Aerospace Centre DLR in Cologne to investigate the effects of simulated spaceflight conditions on brain physiology.
