Contactless respiration monitoring of infants

Five alternative contactless methods for monitoring respiration in infants during the first year of life are evaluated. The methods are: (i) an air-filled mattress system, (ii) an under-mattress pressure sensor, (iii) a magnetometer and magnet, (iv) a capacitance-change detector and (v) a radar reflection system. A battery-powered 2-channel radar system is described in detail and some results are given of information obtained from overnight recordings in infants.SommaireOn a évalué cing méthodes différentes de contrôle sans contact de la respiration infantile pendant la première année d'existence. Ces méthodes sont les suivantes: (i) système de matelas rempli d'air; (ii) détectuer de pression sous matelas; (iii) magnétomètre à aimant; (iv) détecteur de changement de capacité et (v) système de réflection radar. L'article décrit en détail un système radar à deux canaux à pile et présente quelques résultats d'informations obtenues à partir d'enregistrements effectués chez des enfants au cours de la nuit.ZusammenfassungEs wurden fünf alternative kontaktlose Verfahren zur Atemüberwachung von Säuglingen während des ersten Lebensjahres beurteilt. Es handelte sich um folgende Verfahren: (i) das luftgefüllte Matratzensystem, (ii) Druckfühler unter der Matratze, (iii) Magnetometer und Magnet, (iv) Kapazitanzänderungssucher und (v) ein Radar-Reflektionssystem. Ein batteriebetriebenes Radarsystem mit zwei Kanälen wird genauer beschrieben, und es werden einige Ergebnisse in Form von Daten aus während der Nacht an Säuglingen vorgenommenen Aufzeichnungen angegeben.
