Nitrous oxide, oo sidoo kale loo yaqaano gaasta qosolka, waxay ka heshaa adeegsigeeda wax soo saarka kareemka iyadoo ay ugu wacan tahay sifooyinkeeda gaarka ah ee ka dhigaya inuu si fudud ugu milmo kareemka kana ilaaliyo kareemka inuu oksaydheeyo.Nitrous oxide waxaa loo isticmaalaa kareemka Darwishkasababtoo ah waxay u shaqeysaa sida kicinta, taas oo u oggolaanaysa in kareemka laga soo saaro qasaacad si khafiif ah oo jilicsan. Marka nitrous oxide laga soo daayo qasaca, way balaadhaa oo waxay abuurtaa goobooyin kareemka, taasoo siinaysa joogtaynta hawo ee la rabo. Intaa waxaa dheer, nitrous oxide waxay leedahay dhadhan yar oo macaan, taas oo wanaajisa dhadhanka kareemka Darwishka. Tani waxay ka dhigaysaa doorasho caan ah oo lagu abuurayo macmacaan macaan oo muuqaal ah.
Marka nitrous oxide loo isticmaalo qasacadaha kareemka si loo bixiyo kareemka, gaaska kala diri wuxuu abuuraa xumbo, taasoo keentay in kareemku uu noqdo baraf, oo la mid ah sida kaarboon laba ogsaydhku u abuuro xumbo soodhaha qasacadaysan. Marka la barbardhigo ogsijiinta, nitrous oxide waxay ballaarin kartaa mugga kareemka ilaa afar jeer, taasoo ka dhigaysa kareemka mid fudud oo jilicsan.
Marka lagu daro sifooyinka fidinta, nitrous oxide sidoo kale waxay soo bandhigtaa saamaynta bakteeriyada, taasoo la micno ah inay joojiso koritaanka bakteeriyada. Tani waxay u ogolaanaysaa qasacadaha kareemka ka buuxo ee lagu darey oksaydhka nitrous in lagu kaydiyo qaboojiyaha ilaa laba toddobaad iyada oo aan laga welwelin burburinta kareemka.
Nitrous oxide waa cunto lagu daro badbaado leh oo ay ansixisay Maamulka Cuntada iyo Dawooyinka ee Maraykanka (FDA). Marka loo eego dhinaca caafimaadka, isticmaalka nitrous oxide ee gasacadaha kiriimka ayaa loo arkaa mid badbaado leh sababtoo ah tirada ugu yar iyo suurtogalnimada hoose ee waxyeellada u geysata jidhka bini'aadamka. Si kastaba ha ahaatee, waxaa muhiim ah in la ogaado in neefsashada ula kac ah ee nitrous oxide ee ujeedooyinka madadaalada ay tahay dabeecad aan fiicneyn oo ay u horseedi karto arrimo caafimaad.
Gebogebadii, codsiga nitrous oxide ee gasacadaha kareemku si wax ku ool ah uma soo saaro kareem qalafsan oo kaliya laakiin sidoo kale waxay hubisaa inay cusub tahay iyada oo loo marayo sifooyinka bakteeriyada. Hufnaanta habka kareem-samaynta iyo dammaanadda tayada alaabada ayaa ka dhigaya nitrous oxide doorasho ku habboon soo saarista kareemka duriinka. Helitaanka baahsanaanta iyo ku habboonaanta codsiyada cuntada ayaa sii sharraxaysa sababta nitrous oxide si weyn loogu isticmaalo soosaarka kareemka.
Marka la soo koobo, codsiga badan ee loo yaqaan 'nitrous oxide' ee samaynta kareemka, iyada oo leh awoodda ay u leedahay in ay abuurto muuqaal qalafsan oo ay ilaaliso cusbada, waxay ka dhigaysaa doorasho caan ah oo soo saarista kareemka Darwishka.
