Abstract

DADOS ADICIONAIS PARA MELHORAR O DESEMPENHO DE UM SISTEMA DE MONITORAMENTO CONTÍNUO DE GLICOSE. São fornecidos sistemas e métodos para a operação do dispositivo de monitoramento contínuo de analitos (CAM). Em um exemplo, um método compreende a conversão de um primeiro fluxo de dados de analito em valores de analito refletivos de uma concentração biológica do analito, a obtenção de um ou mais fluxos de dados adicionais de um ou mais sensores adjuvantes, a inferência com base no primeiro fluxo de dados e em um ou mais fluxos de dados adicionais de que a conversão do primeiro fluxo de dados em valores de analito é predita como imprecisa e a tomada de medidas mitigadoras para evitar que valores de analito imprecisos sejam comunicados a um usuário. Desta forma, medidas corretivas podem ser tomadas para melhorar a operação geral do dispositivo CAM, a qualidade dos dados fornecidos através de um dispositivo CAM pode ser melhorada e o perfil de saúde e segurança do usuário associado ao dispositivo de monitoramento contínuo de analito pode ser melhorado.
