I-nitrous oxide, evame ukwaziwa ngokuthi igesi ehlekayo, isetshenziselwe izinjongo ezihlukahlukene ezihlanganisa izinhlelo zezokwelapha nezokupheka. Kodwa-ke, kunomehluko omkhulu phakathi kwebanga lezokwelapha le-nitrous oxide nebanga lokudla le-nitrous oxide okubalulekile ukuqondwa.
I-Nitrous oxide (N2O) igesi engenambala, engashi enephunga elimnandi kanye nokunambitha. Isetshenziswe iminyaka engaphezu kwekhulu ezilungiselelweni zezokwelapha namazinyo njenge-anesthetic kanye ne-analgesic. Ukwengeza, isetshenziswa embonini yokudla njenge-propellant kuma-dispensers okhilimu ophehliwe nasekukhiqizeni imikhiqizo ethile yokudla.
I-nitrous oxide yezinga lezokwelapha ikhiqizwa futhi ihlanjululwe ukuze kuhlangatshezwane namazinga aqinile abekwe ama-ejensi alawulayo afana ne-United States Pharmacopeia (USP) noma i-European Pharmacopoeia (Ph. Eur.). Ihlolwa kanzima ukuze kuqinisekiswe ukuthi ayinakho ukungcola kanye nokungcola, okuyenza iphephe ukusetshenziswa ezinqubweni zezokwelapha. I-nitrous oxide yezinga lezokwelapha ngokuvamile isetshenziselwa ukulawula ubuhlungu phakathi nezinqubo ezincane zezokwelapha kanye nokwelashwa kwamazinyo.
Ngokolunye uhlangothi,ukudla grade nitrous oxideyenzelwe ngokukhethekile ukusetshenziswa ezindaweni zokupheka. Ivame ukusetshenziswa njenge-propellant emathinini e-aerosol ukwakha ukhilimu ophehliwe namanye amagwebu. I-nitrous oxide yezinga lokudla ilawulwa iziphathimandla zokuphepha kokudla ukuze kuqinisekiswe ukuthi ihlangabezana nezindinganiso zokuhlanzeka ezidingekayo ukuze zisetshenziswe. Nakuba iphephile ukuthi isetshenziswe ekulungiseni ukudla, ayifanele ukusetshenziswa kwezokwelapha noma kwamazinyo ngenxa yokuba khona kokungcola okungenzeka.
Umehluko oyinhloko phakathi kwebanga lezokwelapha le-nitrous oxide nebanga lokudla i-nitrous oxide isebumsulwa nasekusetshenzisweni okuhlosiwe. I-nitrous oxide yezinga lezokwelapha ingena ezinqubweni zokuhlanza eziqinile nokuhlolwa ukuze kuqinisekiswe ukuthi ihlangabezana nezindinganiso eziphakeme kakhulu zezicelo zezokwelapha. Kubalulekile ekuphepheni kwesiguli ukuthi i-nitrous oxide yezinga lezokwelapha kuphela isetshenziswe ezilungiselelweni zokunakekelwa kwezempilo ukuze kugwenywe izingozi zempilo ezingaba khona ezihlobene nokungcola.
Ngokuphambene, i-nitrous oxide yebanga lokudla yakhelwe ngokukhethekile ukusetshenziswa kokupheka futhi ithobelana nemithetho ebekwe iziphathimandla zokuphepha kokudla. Nakuba ingase iphephe ukuthi isetshenziswe lapho kulungiswa ukudla, ayifanele izinjongo zezokwelapha ngenxa yokuba khona kokungcola okungase kube yingozi empilweni ezigulini.
Ukusebenzisa ibanga elifanele le-nitrous oxide kubalulekile ekuqinisekiseni ukuphepha kuzo zombili izilungiselelo zezokwelapha nezokupheka. Ochwepheshe bezokwelapha kufanele babambelele eziqondisweni nemithethonqubo eqinile lapho besebenzisa i-nitrous oxide yokubulala izinzwa noma ukulawula ubuhlungu ukuze kuncishiswe ingozi yemiphumela emibi ezigulini. Ngokufanayo, ochwepheshe bemboni yezokudla kufanele baqinisekise ukuthi i-nitrous oxide yezinga lokudla isetshenziswa ngokuzibophezela ngokuhambisana nezindinganiso zokuphepha kokudla ukuze kuvinjelwe noma yiziphi izingozi ezingaba khona ezihlobene nokunukubezeka.
Kubalulekile futhi ukuthi abathengi baqaphele umehluko phakathi kwebanga lezokwelapha kanye nebanga lokudla i-nitrous oxide lapho besebenzisa imikhiqizo equkethe le gesi. Kungakhathaliseki ukuthi usebenzisa amakhilimu aphehliwe ekhaya noma wenza izinqubo zezokwelapha, ukuqonda ukubaluleka kokusebenzisa izinga elifanele le-nitrous oxide kungasiza ekuvimbeleni noma yiziphi izingozi ezingahlosiwe empilweni.
Ama-ejensi alawulayo afana ne-US Food and Drug Administration (FDA) kanye ne-European Medicines Agency (EMA) adlala indima ebalulekile ekwengameleni ukukhiqizwa, ukusatshalaliswa, kanye nokusetshenziswa kwebanga lezokwelapha le-nitrous oxide. Lawa ma-ejensi abeka izindinganiso eziqinile zokuhlanzeka, ukulebula, nokubhala ukuze kuqinisekiswe ukuthi kuphela ikhwalithi ephezulu ye-nitrous oxide esetshenziswa kuzilungiselelo zokunakekelwa kwezempilo.
Ngokufanayo, iziphathimandla zokuphepha kokudla ezifana ne-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA) zilawula ukukhiqizwa nokusetshenziswa kwebanga lokudla i-nitrous oxide ukuvikela impilo yabathengi. Lawa ma-ejensi asungula imihlahlandlela yokuhlanzeka, ukulebula, nokusetshenziswa okuvumelekile kwe-nitrous oxide yezinga lokudla ekusetshenzisweni kokupheka.
Sengiphetha, umehluko phakathi kwebanga lezokwelapha le-nitrous oxide nebanga lokudla i-nitrous oxide ubalulekile ekuqondeni ukusetshenziswa kwazo okuhlukene nokucatshangelwa kokuphepha. I-nitrous oxide yezinga lezokwelapha ihlanzwa ngokuqinile futhi ihlolwe ukuze ihlangabezane nezindinganiso eziphakeme kakhulu zezicelo zezokwelapha, kuyilapho i-nitrous oxide yezinga lokudla ihloselwe ukusetshenziswa kwezokupheka futhi ihambisana nemithetho yokuphepha kokudla. Ngokubona lo mehluko nokunamathela ezindinganisweni zokulawula, ochwepheshe bezokunakekelwa kwempilo, ochwepheshe bemboni yezokudla, kanye nabathengi bangaqinisekisa ukusetshenziswa okuphephile nokufanelekile kwe-nitrous oxide kuzilungiselelo zabo.
