Visual Control System Based on Nociception-Analgesia Index for Patients in a Vegetative State/Unresponsive Wakefulness Syndrome and Minimally Conscious State

Abstract

Considering people who are in a coma, doctors have to rely on physical clues and information provided by monitoring systems. It is commonly used for patients in a vegetative state, as contact with them is difficult. Taking into account the typical workload of the doctor, they require several tools to monitor the coma depth, since it is hard to perform a clinical evaluation hourly. Therefore, visual perception and monitoring of physical state for coma personnel proved to be more convenient for prompt decision-making. In a number of cases, it would be possible to make a prognosis for their recovery and monitor effectiveness of treatment courses. Visual control system based on RGB led strips according to the ANI range of values was created. In conclusion, the connecting scheme of ANI monitor with the implementation of visual object was presented.
