Kokubili ibhaluni elizikhulisayo (AMBU) kanye nesimo esiphuthumayo sebhola lokuphefumula kungamathuluzi asetshenziselwa ukwesekwa kokuphefumula (ukungenisa umoya okufakelwayo) futhi kokubili kuhlanganisa ikakhulukazi ibhaluni, kodwa kunomehluko othile phakathi kwakho.

Isimo esiphuthumayo sebhola lokuphefumula asizikhuliseli ngokwaso (alikhukhumezi ngokuzenzakalelayo), ngakho-ke kufanele lixhunywe emthonjeni we-oxygen ongaphandle njengesilinda.

Ukuze ugweme i-barotrauma yomzila wokuphefumula wesiguli, kune-valve yokulawula ukucindezela komoya ofakwe emaphashini.

Ibhaluni elizikhulisayo (AMBU) liyazikhulisa ngokwalo, okusho ukuthi lizigcwalisa ngokwalo ngomoya ngemva kokucindezelwa futhi lingase lingaxhunywanga kusilinda (ngaleyo ndlela 'liyakwazi ukuzimela' futhi lisebenziseka kakhulu).

Njengoba i-AMBU ingaqinisekisi ngaso sonke isikhathi ukutholakala kwe-oxygen ephelele, ingaxhunywa endaweni yokugcina amanzi.

Uma kuqhathaniswa ne-AMBU, isimo esiphuthumayo sebhola lokuphefumula sinesikhathi esifushane sokugcwalisa futhi akukho ukuvuza komoya

Isimo esiphuthumayo sebhola lokuphefumula sivumela umthamo omkhulu womoya ukuthi ufakwe umoya kune-AMBU.

Nakuba isimo esiphuthumayo sebhola eliphefumulayo linombozo oxhunywe ngqo ekugcineni kweshubhu le-endotracheal elifakwe esigulini, ibhaluni le-AMBU lixhunywe kumaski obuso okubekwa phezu kobuso besiguli ukuze kuvalwe umlomo nekhala.

Uma iziguli zifakwe intuba, umoya ophuthumayo webhola lokuphefumula kufanele ngaso sonke isikhathi uncanyelwa kunomoya ozinwebayo webhaluni.

Esimeni sokwehluleka ukuphefumula okukhulu nokuntuleka komoyampilo noma ukunqwabelana kwe-carbon dioxide, i-AMBU ikhethwa ukuze kukhishwe isikhutha esingcono.

Uma kuqhathaniswa ne-AMBU, isimo esiphuthumayo sebhola lokuphefumula asinawo ama-valve endlela eyodwa, ivalvu kuphela (i-Marangoni valve) yokulinganisa ukucindezela kwengxube yegesi efakwa emaphashini.

Isimo esiphuthumayo sebhola lokuphefumula ngokuvamile siyalahlwa, kuyilapho i-AMBU ingasetshenziswa izikhathi ezimbalwa

I-AMBU inenzuzo yokudinga indlela ehlasela kancane engadingi ulwazi oluthile lwezokwelapha ukuze isetshenziswe, ngakho isebenziseka kakhulu futhi ilula kune-BBE; ngaphezu kwalokho, i-AMBU inezindleko zokusebenza eziphansi kunezimo eziphuthumayo zebhola lokuphefumula.

Ngakolunye uhlangothi, i-AMBU ayinikezi ngaso sonke isikhathi inani elanele le-oxygen, ngenxa yokuthi kunzima ukuthi imaski ibambelele kahle ebusweni besiguli.

Ukuvala umsebenzi kunenzuzo yokunikeza isiguli inani elanele nelilungisekayo lomoya-mpilo, kodwa unezindleko zokusebenza eziphakeme futhi ukusetshenziswa kwawo kuxhumene ngokuqondile ne-intubation (indlela ehlaselayo neyinkimbinkimbi, ikakhulukazi kulabo abanolwazi oluncane) futhi ingakwazi. ngakho-ke isetshenziswe kuphela ochwepheshe bezempilo abaqeqeshwe kakhulu.
