Imishini yokubulala izinzwa ingamathuluzi abalulekile okuhlinzeka ngezinzwa eziphephile nezisebenzayo ezigulini ngesikhathi sokuhlinzwa.Enye ingxenye ebalulekile yale mishini uhlelo lokuphefumula, olunesibopho sokuletha umoya-mpilo namagesi okubulala izinzwa esigulini.Kunezinhlobo eziningana ezahlukene zezinhlelo zokuphefumula ezitholakalayo, ngayinye inezinzuzo zayo kanye nokubi.Ngakho-ke, iyiphi isistimu yokuphefumula efanelekile yomshini wokubulala izinzwa?
Enye inketho ethandwayo yi-uhlelo lokuphefumula lwendilinga.Lolu hlelo lusebenzisa isiyingi esivaliwe ukuze sijikeleze kabusha amagesi akhishwe umoya, kuncishiswe imfucuza kanye nokugcina amagesi abulala izinzwa.Uhlelo lwendilinga luhlanganisa ne-carbon dioxide absorber, esusa i-carbon dioxide emagesini akhishwe ngaphambi kokuba aphinde ajikelezwe.Umphumela uba uhlelo olusebenza kahle kakhulu futhi olungabizi kakhulu oluletha amanani anembayo omoya-mpilo kanye namagesi okubulala izinzwa esigulini.
Enye inketho uhlelo lwe-Mapleson, olusebenzisa uchungechunge lwamashubhu nama-valve ukuletha amagesi amasha esigulini futhi kukhishwe amagesi akhishwe.Lolu hlelo lusebenza ngezindlela eziningi futhi lungasetshenziswa nangabantu abadala kanye nezingane, okulenza libe yisinqumo esidumile ezikhungweni eziningi zezokwelapha.Nokho, uhlelo lwe-Mapleson lungakwazi ukusebenza kahle kakhulu kunohlelo lwendilinga, futhi lungadinga amazinga okugeleza aphezulu ukuze kugcinwe amazinga anele omoya-mpilo kanye nezinzwa.
Inketho yesithathu isistimu ye-Bain, efana nesistimu ye-Mapleson kodwa ehlanganisa ishubhu le-coaxial eliletha amagesi amasha ngokuqondile endleleni yomoya yesiguli.Lolu hlelo lwaziwa ngokusebenza kahle kwalo kanye nekhono lokuhlinzeka ngamazinga anembile nanembile wokulalisa izinzwa, okwenza kube ukukhetha okudumile kochwepheshe abaningi bezokwelapha.
Ekugcineni, uhlelo lokuphefumula olufanele lomshini wokubulala izinzwa luzoncika ezintweni ezihlukahlukene, okuhlanganisa nezidingo ezithile zesiguli, uhlobo lokuhlinzwa olwenziwayo, kanye nokuthandwa yithimba lezokwelapha.Ochwepheshe bezokwelapha kufanele bacabangele lezi zici ngokucophelela lapho bekhetha isistimu yokuphefumula yomshini wabo wokubulala izinzwa ukuze baqinisekise imiphumela engcono kakhulu ezigulini zabo.
Uma ungathanda ukufunda okwengeziwe mayelana nezinhlobo ezahlukene zesistimu yokuphefumula etholakalayo emishinini yokubulala izinzwa noma udinga usizo lokukhetha isistimu elungile yesikhungo sakho sezokwelapha, thintana nomhlinzeki wezinto ezibulala izinzwa oqeqeshiwe noma khuluma nomnyango wokubulala izinzwa esibhedlela sakho ukuze uthole isiqondiso.
Sengiphetha, ukukhetha uhlelo lokuphefumula olufanele lomshini wokubulala izinzwa kuyisinqumo esibucayi esingaba nomthelela ekuphepheni kwesiguli kanye nemiphumela.Ngokucabangela ngokucophelela izinketho nokukhetha uhlelo oluhlangabezana kangcono nezidingo zeziguli zabo, ochwepheshe bezokwelapha banganikeza i-anesthesia ephephile nephumelelayo phakathi nezinqubo zokuhlinzwa.
