“…Thus, measurands can be carried out d in difficult to access parts of the human body with greater concentration sensitivity. Lastly, it is technologically possible to bundle multiple sensors with different measurement capabilities can be fused into a single probe as a packaged instrument, and hence potentially increasing useful information content [10][11][12][13][14]. Optical fiber technology offers a convenient, affordable, safe and effective approach for the delivery and collection of light to and from the tissue region of interest, and has been employed clinically since the 1960s [5].…”

“…However, the technique only provides discrete measurements. In order to overcome this limitation, an optical fibre sensor was developed (79). This is based on the utilisation of a CO2 sensing layer fixed at the end of an optical fibre catheter that is connected to an optoelectronic unit.…”

“…Este tipo de sensor de pH pode ser empregado em sistemas específicos, como, por ex., no monitoramento contínuo de dióxido de carbono em suco gástrico 43 , com as vantagens inerentes de um sensor óptico com relação a um eletroquímico, que foram anteriormente descritas, proporcionando medidas em tempo real, que não são obtidas com o procedimento convencional de gasometria 49 . Finalmente, as determinações de pH podem ser efetuadas com base em medidas de absorbância, empregando-se um espectrofotômetro comercial.…”
