Nocturnal Wheeze Measurement in Preschool Children

Abstract

Overall, the wheeze rate in young children is low, but seems to increase over nighttime. Almost 50% of the children have sporadic wheeze during the night. Although higher nocturnal wheeze rates are related to increased respiratory system resistance, it is not related to clinical wheezing symptoms.

The highs and lows of wheezing: A review of the most popular adventitious lung sound

“…A multi‐sensor array system for “vibration response imaging” (VRIxp, Deep Breeze, Or‐Akiva, Israel), that is, for the spatial mapping of chest sounds, was FDA approved in 2008 and has been used in a study of wheezes . The quantitation of recorded nocturnal wheezing had been a tedious manual job before extended data capture and automated analyzes became available with systems like the WHolter (KarmelSonix, Haifa, Israel) or the recently introduced LEOsound (Heinen & Löwenstein, Bad Ems, Germany). Interested readers are directed to a more detailed review and appraisal of automated lung sound analysis for asthma…”

Relationship between computerized wheeze detection and lung function parameters in young infants

“…Overnight recordings of lung sounds in children 6–14 years of age using the PulmoTrack® showed a good correlation between the duration of nocturnal wheezing and spirometric indices of asthma activity . Use of the same device in 3‐year‐old nocturnal wheezers revealed a significant correlation between wheeze and R rs measured by the interrupter technique …”

“…CORSA has several advantages compared with clinician‐performed auscultation, including better compliance with objective criteria that define respiratory sounds, as well as reduced inter‐observer variability . Moreover, CORSA can be used in continuous overnight monitoring to quantify nocturnal wheeze . Although conventional lung function testing (LFT) is the gold standard to detect bronchial obstruction, CORSA is much easier to perform.…”

LEOSound – Ein innovatives Verfahren zum akustischen Langzeit-Monitoring von asthmatischen Symptomen (Wheezing und Husten) bei Kindern und Erwachsenen

“…"Pre-school wheeze" ! Viele Studien bei Kindern im Vorschulalter beschäftigen sich mit dem sogenannten "pre-school wheeze" unter der speziellen Fragestellung eines Prädiktionsfaktors für ein manifestes Asthma bronchiale [1,2,6,[19][20][21]. Da Wheezing häufig bei Kindern mit viralen respiratorischen Infekten gefunden wird, hat man aus pragmatischen Gründen eine Unterteilung in "episodisch auftretendes (meist durch eine virale Infektion der unteren Atemwege bedingt)" und "multiple-trigger wheeze" vorgenommen [21].…”

“…Da Wheezing häufig bei Kindern mit viralen respiratorischen Infekten gefunden wird, hat man aus pragmatischen Gründen eine Unterteilung in "episodisch auftretendes (meist durch eine virale Infektion der unteren Atemwege bedingt)" und "multiple-trigger wheeze" vorgenommen [21]. [1,19]. Wheezing-Ereignisse, die seitens der Eltern oder der Kinder hörbar wahrgenommen werden, dürften bereits ausgeprägten Asthmaanfällen entsprechen.…”
