Over the past years, various systems and techniques enabling unobtrusive/minimally obtrusive acquisition of physiological signals have evolved. These systems and techniques open up novel opportunities for sleep medicine. This work provides an overview of unobtrusive systems and techniques to monitor cardiorespiratory function. We present basic principles of mechanical, radar-based, optical, and electrical measurements, and present concrete examples focused on how such systems and techniques can be used for sleep medicine. This work demonstrates the high potential of unobtrusive acquisition. Furthermore, it highlights the need for a standardized evaluation of the available techniques and demonstrates the demand for sleep-specific developments of available techniques in interdisciplinary collaborations.

Kontaktlose Erfassung kardiorespiratorischer Signale

Verfügbare Verfahren und Perspektiven für die Schlafmedizin


In den letzten Jahren wurden verschiedene Systeme und Verfahren entwickelt, die es ermöglichen, kontaktlos bzw. minimal kontaktgebunden physiologische Signale zu erfassen. Die aktuellen Entwicklungen eröffnen für die Schlafmedizin neue Möglichkeiten. In dieser Arbeit wird ein Überblick über kontaktlose Techniken zum Monitoring der kardiorespiratorischen Aktivität gegeben. Die Autoren stellen die Grundlagen mechanischer, radarbasierter, optischer und elektrischer Messverfahren vor und geben konkrete Beispiele mit einem Fokus darauf, wie eine Nutzung für die Schlafmedizin aussehen kann. Es zeigt sich, dass die heutigen Systeme vielversprechende Möglichkeiten der Signalerfassung bieten, hinsichtlich zukünftiger Anwendungen allerdings eine standardisierte Evaluation verfügbarer Techniken und Weiterentwicklungen für den spezifischen Bedarf der Schlafmedizin in interdisziplinären Zusammenarbeiten erforderlich ist.
