Abstract

DISPOSITIVO DE DETECçãO FISIOLóGICA PARA A MEDIçãO DE pCO~ 2~ A dispositivo de detecção fisiológica para a medição de pCO~ 2~ inclui uma câmara fechada delimitada, pelo menos parcialmente, por uma mecanismo permeável a dióxido de carbono (12). Existem dois eletrodos (10) na câmara. A câmara contém um líquido substancialmente livre de eletrólito com eletrodos (10) e a membrana (12). o Líquido contém um excipiente não iónico a fim de impedir a entrada de água por causa de um gradiente osmótico através da membrana (12) em uso.
