Cov pa oxygen concentration ntau ntawm cov tshuab hluav taws xob hauv tsev yog qhov loj, feem ntau nyob rau hauv thaj tsam ntawm 30% -90% ± 3%.Nrog rau qhov nruab nrab cov pa oxygen concentration ntawm li 35%, nws tsim nyog rau cov neeg ua haujlwm hauv chaw ua haujlwm thiab cov tub ntxhais kawm.Nws tuaj yeem tshem tawm qaug zog, rov qab los thiab txhim kho kev pw tsaug zog;Feem ntau 60% oxygen concentration yog haum rau cov neeg laus, siv mus ntev, cov neeg laus tuaj yeem ua rau lub neej ntev.Rau cov neeg mob, 90% oxygen concentration raws li cov qauv kev kho mob oxygen.
Raws li cov kev cai cuam tshuam ntawm Lub Xeev Food and Drug Administration, kev kho mob oxygen yuav tsum ncav cuag 93% ua ntej nws tuaj yeem siv rau hauv kev kho mob.Vim li cas cov pa oxygen concentration rau kev kho mob oxygen generators 93% ± 3%?
Qhov laj thawj tseem ceeb yog tias tib neeg lub cev tseem yuav nqus tau qee cov pa uas muaj 20.98% oxygen purity thaum nqus pa nrog kev pab los ntawm cov pa oxygen concentrator, yog li qhov tseeb nqus pa oxygen concentration kuj yuav diluted raws li.Raws li kev ntsuam xyuas, cov pa oxygen concentration ntawm cov pa nqus pa feem ntau yog li 45%.Raws li cov yam ntxwv ntawm tib neeg lub cev, kev nqus pa oxygen yuav tsum mus txog 32-theem attenuation txheej txheem.Qhov tseeb, thaum cov pa oxygen concentration yog li 93%, cov pa oxygen siv los ntawm tib neeg lub cev tom qab nqus pa oxygen yog li 30%.Yog li ntawd, txhawm rau kom ntseeg tau tias tus neeg mob tuaj yeem tau txais kev kho cov pa oxygen ib txwm, cov pa oxygen yuav tsum ncav cuag li 93% kom ntseeg tau tias tus neeg mob xav tau oxygen.
Cov khoom siv kho mob cov pa oxygen yog nyob rau hauv chav kawm thib ob ntawm kev tswj xyuas cov cuab yeej kho mob raws li cov cai, thiab tau txais kev pom zoo thiab sau npe los ntawm lub tuam tsev saib xyuas zaub mov thiab tshuaj hauv lub xeev.Oxygen generators yog tag nrho nyob rau hauv kev tswj hwm ntawm lub chaw saib xyuas zaub mov thiab tshuaj.Lawv tsis tsuas yog tsim nyog rau kev pab kho mob ntawm cov neeg mob hauv tsev kho mob thiab cov kev xav tau oxygen ntawm kev lag luam tshwj xeeb, tab sis kuj muab kev kho mob oxygen zoo rau cov neeg mob uas xav tau kev kho mob hauv tsev.
