Abstract

SISTEMA E MÉTODOS PARA MONITORAMENTO INTRACRANIANO NÃO INVASIVO BASEADO EM IMPEDÂNCIA. A presente invenção refere-se a um sistema para avaliar trauma cerebral através de mudanças regionais na impedância do teci-do. A presente descrição descreve um sistema para monitoramento intracraniano não invasivo, compreendendo dois ou mais eletrodos que afetam dispostos entre um local condutor de um crânio de um paciente e um local no couro cabeludo do paciente, dois ou mais eletrodos afetados dispostos entre a localização condutora do crânio do paciente e a localização no couro cabeludo do pacientee circuito de processamento configurado para aplicar um estímulo elétrico entre os dois ou mais eletrodos que afetam, medir um diferencial de estímulo elétrico entre os dois ou mais eletrodos afetados, calcular, para os dois ou mais eletrodos afetados, um valor de uma métrica de impedância, e identificar, com base no valor calculado da métrica de impedância, uma condição de saúde do paciente.
