Rashin motsi na iska

Plethysmography motsi iska ( ADP, kuma aka sani da gaba ɗaya iska iska displacement plethysmography ) sanannen kuma ingantaccen hanyar densitometric a kimiyance don auna abubuwan jikin ɗan adam. ADP yana dogara ne akan ka'idodi iri ɗaya da daidaitaccen tsarin zinare na ma'aunin hydrostatic, amma ta hanyar fasaha na densitometric wanda ke amfani da ƙaurawar iska maimakon nutsewar ruwa. Plethysmography na gudun hijira yana ba da fa'idodi da yawa akan kafaffen hanyoyin tunani, gami da sauri, jin daɗi, sarrafa kansa, tsarin aunawa mara ƙarfi, da amintaccen tsari, kuma yana ɗaukar nau'ikan batutuwa daban-daban (misali, yara, kiba, tsofaffi, da nakasassu).
