title: Biotelemetry, based on optical transmission.
abstract: Biotelemetry has developed as a reliable alternative to continuous monitoring of physiological variables under realistic circumstances of data assessment. For incorporation in clinical routine the lack of an adequate number of biotelemetry frequencies forms a severe disadvantage. This paper shows a way to circumvent the problem, namely by using infrared light as the carrier for the transmission system. Use of infrared light is limited to indoor applications, and a number of additional restrictions have to be accepted, but on the other hand infrared telemetry opens new possibilities not known to radiotelemetry, especially suited for clinical applications.
