Khoom Taw Qhia
Nitrous oxide, feem ntau hu ua luag nyav los yog nitrous, yog cov tshuaj lom neeg, ib qho oxide ntawm nitrogen nrog cov mis N2O. Nyob rau hauv chav tsev kub, nws yog ib tug tsis muaj kob uas tsis yog-flammable gas, nrog ib tug me ntsis metallic ntxhiab thiab saj. Thaum kub siab, nitrous oxide yog lub zog oxidizer zoo ib yam li molecular oxygen.
Nitrous oxide muaj kev siv tshuaj kho mob tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv kev phais thiab kev kho hniav, rau nws cov tshuaj loog thiab txo qhov mob. Nws lub npe "laughing gas", coined los ntawm Humphry Davy, yog vim lub euphoric cuam tshuam thaum nqus tau nws, ib yam khoom uas tau coj mus rau nws kev lom zem siv raws li ib tug dissociative anaesthetic. Nws yog nyob rau hauv Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb Daim Ntawv Teev Cov Tshuaj Tseem Ceeb, cov tshuaj siv tau zoo thiab nyab xeeb tshaj plaws uas xav tau hauv kev noj qab haus huv.[2] Nws kuj yog siv los ua oxidizer nyob rau hauv foob pob hluav taws propellants, thiab nyob rau hauv kev sib tw lub cev muaj zog los ua kom lub zog tso zis ntawm lub cav.

Kev pab thawj zaug
INHALATION: Yog tias muaj kev phiv tshwm sim, tshem tawm mus rau qhov chaw tsis muaj kab mob. Muab cov pa ua pa tawm yog tias tsis yog
ua pa. Yog tias ua pa nyuaj, oxygen yuav tsum tau tswj hwm los ntawm cov neeg ua haujlwm tsim nyog. Tau tam sim ntawd
kev kho mob.
Kev Tiv Thaiv Cov tawv nqaij: Yog tias frostbite los yog khov, tam sim ntawd yaug nrog dej sov kom ntau (105-115 F; 41-46 C). Tsis txhob siv dej kub. Yog tias dej sov tsis muaj, maj mam qhwv cov khoom cuam tshuam rau hauv
daim pam. Tau txais kev kho mob tam sim ntawd.
KEV TIV THAIV: Tshem lub qhov muag nrog dej kom ntau.
TSEEM CEEB: Yog tias nqos tau ntau, mus ntsib kws kho mob.
CEEB TOOM RAU PHYSICIAN: Rau kev nqus pa, xav txog oxygen.
Siv
1.Rocket motors
Nitrous oxide tuaj yeem siv los ua oxidizer hauv lub tshuab foob pob hluav taws. Qhov no yog qhov zoo dua lwm cov oxidisers nyob rau hauv uas nws tsis yog tsuas yog tsis muaj tshuaj lom, tab sis vim nws ruaj khov nyob rau hauv chav tsev kub kuj yog yooj yim rau khaws cia thiab kuj muaj kev nyab xeeb dua los nqa ntawm lub davhlau. Raws li qhov txiaj ntsig thib ob, nws tuaj yeem decomposed yooj yim los ua pa ua pa. Nws lub siab ntom ntom thiab cov khoom ntim qis (thaum tswj hwm ntawm qhov kub tsawg) kom nws tau muaj kev sib tw ntau nrog khaws cov roj av siab.
2.Internal combustion engine —(Nitrous oxide cav)
Hauv kev sib tw tsheb, nitrous oxide (feem ntau hu ua "nitrous") tso cai rau lub cav hlawv roj ntau dua los ntawm kev muab cov pa ntau dua li huab cua ib leeg, uas ua rau muaj hluav taws xob ntau dua.
Automotive-qib kua nitrous oxide txawv me ntsis ntawm kev kho mob-qib nitrous oxide. Ib qho me me ntawm sulfur dioxide (SO2) ntxiv los tiv thaiv kev siv tshuaj yeeb. Kev ntxuav ntau dhau los ntawm lub hauv paus (xws li sodium hydroxide) tuaj yeem tshem tawm qhov no, txo cov corrosive zog pom thaum SO2 ntxiv oxidised thaum combustion rau sulfuric acid, ua kom emissions huv si.
3.Aerosol propellant
Cov roj tau pom zoo siv los ua cov khoom noj ntxiv (tseem hu ua E942), tshwj xeeb tshaj yog cov tshuaj tsuag aerosol. Nws feem ntau siv nyob rau hauv cov ntsiab lus no yog nyob rau hauv aerosol whipped cream canisters, ua noj tshuaj tsuag, thiab raws li ib tug inert gas siv los tshem tawm oxygen nyob rau hauv thiaj li yuav inhibit cov kab mob loj hlob nyob rau hauv lub ntim ntawm qos yaj ywm chips thiab lwm yam khoom noj txom ncauj zoo sib xws.
Ib yam li ntawd, cov tshuaj tsuag ua noj, uas yog tsim los ntawm ntau hom roj ua ke nrog lecithin (ib qho emulsifier), tuaj yeem siv nitrous oxide ua ib qho kev txhawb nqa. Lwm cov tshuaj tiv thaiv uas siv los ua cov tshuaj tsuag muaj xws li cov khoom noj khoom haus cawv thiab propane.
4.Medicine —–Nitrous oxide (cov tshuaj)
Nitrous oxide tau siv hauv kev kho hniav thiab phais, ua tshuaj loog thiab tshuaj loog, txij li xyoo 1844.
Nitrous oxide yog ib qho tsis muaj zog ua kom loog, thiab yog li feem ntau tsis yog siv ib leeg hauv kev siv tshuaj loog, tab sis siv los ua cov pa roj (sib xyaw nrog oxygen) rau cov tshuaj loog muaj zog dua xws li sevoflurane lossis desflurane. Nws muaj qhov tsawg kawg nkaus alveolar concentration ntawm 105% thiab cov ntshav / roj faib coefficient ntawm 0.46. Txawm li cas los xij, kev siv nitrous oxide hauv tshuaj loog, tuaj yeem ua rau muaj kev pheej hmoo ntawm xeev siab thiab ntuav tom qab.
Hauv tebchaws Aas Kiv thiab Canada, Entonox thiab Nitronox feem ntau yog siv los ntawm cov neeg caij tsheb thauj neeg mob (xws li cov kws kho mob uas tsis tau sau npe) ua cov pa tshuaj tua kab mob sai thiab muaj txiaj ntsig zoo.
50% nitrous oxide tuaj yeem txiav txim siab rau kev siv los ntawm kev cob qhia tsis yog tus kws tshaj lij pabcuam thawj zaug hauv cov chaw kho mob prehospital, muab cov txheeb ze yooj yim thiab kev nyab xeeb ntawm kev tswj hwm 50% nitrous oxide ua tshuaj tua kab mob. Kev thim rov qab sai ntawm nws cov txiaj ntsig tseem yuav tiv thaiv nws los ntawm kev kuaj mob ua ntej.
5. Kev siv ua si
Kev ua si ua pa ntawm nitrous oxide, nrog rau lub hom phiaj ntawm kev ua kom zoo siab thiab / lossis kev pom me ntsis, pib ua qhov tshwm sim rau cov chav kawm ntawv Askiv nyob rau xyoo 1799, hu ua "laughing gas tog".
Hauv tebchaws United Kingdom, raws li xyoo 2014, nitrous oxide tau kwv yees siv los ntawm yuav luag ib nrab lab cov tub ntxhais hluas thaum hmo ntuj, kev ua koob tsheej, thiab tog. Txoj cai lij choj ntawm qhov kev siv no txawv ntawm lub tebchaws mus rau ib lub tebchaws, thiab txawm tias los ntawm lub nroog mus rau lub nroog hauv qee lub tebchaws.
