Yuav luag txhua yam muaj sia xav tau oxygenkom ciaj sia, tshwj xeeb tshaj yograutib neeg.Tib neeg xav tau oxygen kom nyob,thiab covQhov tsawg kawg nkaus oxygen concentration hauv huab cua xav tau rau tib neeg ua pa yog 19.5 feem pua.Lub OSHA txiav txim siab qhov zoo tshaj plaws ntawm cov pa oxygen hauv huab cua rauneegkhiav ntawm 19.5 thiab 23.5 feem pua.Tab sis dab tsi's qhov tsawg kawg nkaus oxygen concentration raucov neeg mob uas xav tau akho mob oxygenlub tshuab hluav taws xob?
Lub purity ntawm lub raj mis kho mob oxygen yog ≥ 99.5%, thiab tsis muaj oxygen concentration tau teev tseg rau kev kho mob oxygen generator.Tab sis cov txheej txheem tsim nyog rau cov khoom siv oxygen tau muab.Cov khoom siv kho mob molecular sieve oxygen tsim cov pa oxygen los ntawm molecular sieve hloov pauv cov txheej txheem siab adsorption, thiab oxygen concentration yuav tsum yog 90% ~ 96% (VN).Feem ntau hais lus, tsis muaj cov pa kho mob tuaj yeem muab tso rau hauv kev kho mob tshwj tsis yog tias cov pa oxygen nce mus txog 93%.
Cov neeg mob yuav nqus tau pa thaum siv lubkho mob oxygen generator, yog li diluting cov pa concentration.Cov pa oxygen concentration nqus los ntawm tib neeg lub cev kuj yuav raug txo txawm tias siv lub tshuab hluav taws xob kho mob vim yog cov qauv ntawm tib neeg lub cev.Cov pa oxygen concentration yuav tsum ua tau raws li tus qauv yam tsawg kawg nkaus (93%) kom ntseeg tau tias cov neeg mob tuaj yeem nqus tau cov pa oxygen txaus.
Tam sim no, kev kho mob oxygen generators nrog 93% oxygen concentration muaj cov cuab yeej paub tab.Ntev npaum li cov khoom tuaj yeem ua haujlwm ib txwm siv, nws tuaj yeem ua kom cov pa oxygen hauv cov neeg mob thiab tsev kho mob.Tab sis lub tsev lossis kev saib xyuas kev noj qab haus huv lub tshuab hluav taws xob oxygen yuav txo qis cov pa oxygen vim yog cov qauv tsim khoom tsis nruj thiab cov qauv, thiab nws tsis yog qhov loj heev yog tias lub tshuab hluav taws xob oxygen kho mob tsuas yog siv hauv tsev rau lub hom phiaj ntawm kev kho mob, es tsis txhob muaj xwm txheej ceev.Xaiv tus kws tshaj lij lub tshuab hluav taws xob lossis mus rau hauv tsev kho mob ntau zaus rau kev kho cov pa oxygen yog tias tus neeg mob xav tau kev kho oxygen nruj heev los kho cov tsis muaj oxygen.
