Abstract: Most advances in monitoring have been associated with the development of new clinical measurements, or improvements in the processing of existing ones to enhance their information content or validity. It is also possible to enhance monitoring systems in quite a different way, by automating the interpretation of signals. Rather than simply displaying measurements for clinicians to interpret, monitoring devices can assist clinicians in the task of interpretation itself. Such advances are made possible through developments in the fields of signal processing, pattern recognition and artificial intelligence (AI). This paper presents an introduction for clinicians to the basic problems that need to be solved, and reviews the major technologies available at present.
