Abstract

trata-se de o tempo de repreenchimento capilar (crt) de um paciente ser um importante recurso na determinação da saúde do sistema cardiovascular ? rápida reperfusão da microcirculação (ou seja, os capilares) é uma boa indicação de que o sistema cardiovascular tem capacidade de distribuir eficientemente o sangue por todo o corpo. os sistemas atuais são métodos não confiáveis ou subjetivos para testar o crt. adicionalmente, o cálculo do crt não é usado, em geral, no espaço médico adulto à medida que é mais comumente usado na pediatria. o presente pedido descreve um sistema e um método para calcular um crt do paciente com o uso de um dispositivo móvel (102, 200, 300) com uma câmera integrada (204, 302) e fonte de luz (202), ou um mostruário óptico montado na cabeça (300) com o uso de uma fonte de luz (202) em combinação com a luz ambiente para calcular o crt. uma vez que o crt do paciente é calculado, o aplicativo integrado (206, 306) classifica os dados e os envia para o médico do tratamento para revisão.
