Title
(EN) ANALYSIS OF MUCUS CHARACTERISTICS
(FR) ANALYSE DE CARACTÉRISTIQUES DE MUCUS
Abstract
(EN) A system is for analyzing physical characteristics of mucus, in particular during patient respiratory support using a ventilator. A ventilation waveform is sensed (224) and analyzed (226) and an estimate of, or a change in, at least one mucus characteristic can then be determined, namely by utilizing changes in ventilation waveforms (e.g. power spectral density), in particular in a flow waveform and/or a pressure waveform. Mucus characteristic may relate to the physical properties of the mucus itself or the way mucus is distributed in the airway.
(FR) Un système est destiné à analyser des caractéristiques physiques du mucus, plus particulièrement pendant le support respiratoire d'un patient à l'aide d'un ventilateur mécanique. Une forme d'onde de ventilation est détectée (224) et analysée (226) et une estimation de, ou un changement de, au moins une caractéristique de mucus peut ensuite être déterminée, à savoir en utilisant des changements de formes d'onde de ventilation (par exemple la densité spectrale de puissance), plus particulièrement dans une forme d'onde d'écoulement et/ou une forme d'onde de pression. La caractéristique de mucus peut concerner les propriétés physiques du mucus lui-même ou la façon dont le mucus est distribué dans les voies respiratoires.
