Abstract
Opto-electronic systems (OS) are motion analysissystems, employed in different clinical applications. Optoelectronicplethysmograph (OEP) is a particular OS able tomeasure pulmonary volumes, starting from markerdisplacements, placed on the thorax.The aim of this work is to assess the OEP's accuracy on volume measurements, by using a volumetric respiratorysimulator (RS). The RS is realized in order to simulate thehuman quiet breathing and an algorithm computes volumevariations. Different trials have been carried out, by measuringvolume through OEP and comparing with volume computed byalgorithm.Results show OEP accuracy on tidal volume measurementdoes not depend on thorax displacement¶V PDJQLWXGH DQG LWranges from 9% to 20%.Therefore, accuracy of OEP on dynamic volume...movement magnitude.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
