Patient monitoring systems: criteria for evaluation & selection

Patient monitoring is more than just the acquisition and accumulation of physiological data. In order for it to be efficacious in patient diagnosis and treatment, the professional staff must be continuously involved in protocol development, evaluation, and modification. Given the constraints of these tasks, of cost limitations, and of staff interest and expertise, the clinical engineer should develop a rationale for making judgments about patient monitoring systems at his particular site. This rationale should include: evaluation of design criteria from medical, nursing, and engineering standpoints; consideration of the considerable and increasing effect of computers on monitoring; and the intelligent appraisal of technique and system development performed at other sites.
