Complex home monitoring

As the demand for sleep evaluations rises, one response has been to conduct such studies in the home. In this brief review, complex home sleep monitoring systems (those recording at least four channels of physiologic data) on which there is peer-reviewed data are assessed. Four currently available systems met these criteria and are discussed. Each such system has clear strengths and weaknesses. These overall data suggest that home monitoring systems are becoming increasingly complex and more successful in monitoring, the desired variables. This trend is likely to continue.
