Ua kua kho mob oxygen, tseem hu ua kua oxygen lossis LOX, yog ib qho tseem ceeb hauv kev kho mob. Kab lus no yog npaj los muab cov ncauj lus kom ntxaws txog cov kua dej kho mob oxygen, suav nrog nws cov ntsiab lus, kev siv, kev tsim khoom, thiab kev ceev faj txog kev nyab xeeb.

Txhais

Cov kua dej kho mob oxygen hais txog cov pa oxygen uas tau txias thiab compressed rau hauv lub xeev ua kua. Nws yog ib daim ntawv uas muaj oxygen heev thiab siv rau kev kho mob, tshwj xeeb tshaj yog nyob rau hauv kev kho mob ntawm kev ua pa thiab thaum lub sij hawm phais. Cov kua dej kho mob oxygen khaws cia thiab thauj hauv cov thawv tshwj xeeb uas tswj nws qhov kub thiab txias thiab tiv thaiv nws los ntawm evaporating.

Siv

Cov kua dej kho mob oxygen muaj ntau yam kev siv hauv kev lag luam kho mob. Qee qhov kev siv tseem ceeb suav nrog:

1.Kev kho mob ua pa: Cov pa oxygen kho mob feem ntau yog siv rau hauv kev kho mob ua pa kom muab cov pa oxygen ntxiv rau cov neeg mob ua pa xws li mob ntsws obstructive pulmonary (COPD), mob hawb pob, thiab mob ntsws. Nws pab txhim kho qib oxygen hauv cov ntshav, txo cov tsos mob thiab txhim kho kev ua pa tag nrho.

2.Tshuaj loog: Thaum cov txheej txheem phais, cov kua dej kho mob oxygen yog siv ua ke nrog lwm cov pa roj los tswj cov tshuaj loog rau cov neeg mob. Nws ua kom cov neeg mob tau txais cov pa oxygen txaus thaum nyob hauv cov tshuaj loog, tswj lawv cov haujlwm tseem ceeb thiab tiv thaiv hypoxia.

3.Tshuaj kho mob xwm txheej ceev: Cov kua dej kho mob oxygen ua lub luag haujlwm tseem ceeb hauv cov chaw kho mob xwm txheej ceev, xws li tsheb thauj neeg mob thiab chav kho mob xwm txheej ceev. Nws yog siv los tswj cov neeg mob uas muaj kev nyuaj siab ua pa los yog cov neeg uas muaj kev ua pa tsis ua haujlwm. Kev muaj cov kua dej kho mob sai sai tuaj yeem cawm tau txoj sia nyob rau hauv cov xwm txheej zoo li no.

4.Tsev Oxygen Therapy: Qee cov neeg mob uas muaj cov kab mob ua pa ntev yuav tsum tau kho cov pa oxygen mus ntev hauv tsev. Cov kua dej kho mob oxygen muab cov kev daws teeb meem yooj yim thiab muaj txiaj ntsig rau kev xa cov pa oxygen ntxiv rau cov neeg mob no. Nws tuaj yeem khaws cia rau hauv cov thawv ntim me me, tso cai rau cov neeg mob tswj lawv txoj kev txav mus los thaum tau txais cov pa oxygen tsim nyog.

Txoj kev tsim khoom

Kev tsim cov kua dej kho mob oxygen muaj ob peb kauj ruam los xyuas kom meej nws cov purity thiab kev nyab xeeb rau kev siv kho mob. Cov hauv qab no yog cov txheej txheem ntau lawm:

1.Fractional Distillation: Thawj txoj kev siv los tsim cov kua dej kho mob oxygen yog fractional distillation. Cov txheej txheem no suav nrog cua txias thiab compressing cua kom tshem tawm impurities thiab cais cov pa oxygen los ntawm lwm cov pa roj. Tom qab ntawd cov dej ua kua oxygen tau muab khaws cia rau hauv cov thawv tshwj xeeb.

2.Kev huv huv: Tom qab fractional distillation, cov kua pa oxygen nkag mus rau kev ua kom huv ntxiv kom tshem tawm cov impurities lossis cov khoom paug. Cov txheej txheem purification no ua kom ntseeg tau tias cov kua dej kho mob oxygen ua tau raws li cov qauv nruj nruj uas yuav tsum tau siv rau kev kho mob.

Kev Tiv Thaiv Kev Nyab Xeeb

Thaum cov kua dej kho mob oxygen yog qhov tseem ceeb rau kev saib xyuas tus neeg mob, nws kuj ua rau muaj kev nyab xeeb yog tias siv tsis raug lossis siv tsis raug. Nov yog qee qhov kev tiv thaiv kev nyab xeeb tseem ceeb los xav txog:

1.Cia thiab tuav: Cov kua dej kho mob oxygen yuav tsum tau muab khaws cia thiab ua raws li cov lus qhia thiab cov kev cai tsim. Nws yuav tsum tau khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob los tiv thaiv hluav taws.

2.Qhov cua: Kev ua pa kom txaus yog qhov tseem ceeb heev thaum siv cov kua dej kho mob oxygen los tiv thaiv kev sib sau ntawm cov pa uas muaj pa oxygen, uas tuaj yeem ua rau muaj kev pheej hmoo ntawm hluav taws kub lossis tawg.

3.Tsis txhob sib cuag nrog cov khoom siv hluav taws xob: Cov kua dej kho mob yuav tsum tsis txhob kov cov khoom siv hluav taws xob xws li roj, roj, lossis cov khoom siv organic. Cov tshuaj no tuaj yeem hnov ​​​​mob hnyav nrog kua oxygen, ua rau combustion.

4.Kev cob qhia kom raug: Cov tib neeg koom nrog hauv kev tuav thiab kev tswj xyuas cov kua dej kho mob oxygen yuav tsum tau txais kev cob qhia kom raug ntawm nws txoj kev siv nyab xeeb thiab khaws cia. Lawv yuav tsum paub txog qhov muaj feem cuam tshuam nrog cov pa oxygen thiab paub yuav ua li cas teb thaum muaj xwm txheej ceev.

Kev kho mob ua kua oxygen ua lub luag haujlwm tseem ceeb hauv kev kho mob niaj hnub no, muab lub zog thiab yooj yim thauj mus los ntawm cov pa oxygen ntxiv rau cov neeg mob ua pa. Kev nkag siab txog nws cov ntsiab lus, kev siv, kev tsim khoom, thiab kev tiv thaiv kev nyab xeeb yog qhov tseem ceeb rau cov kws kho mob koom nrog hauv nws txoj kev tswj hwm. Los ntawm kev ua raws li cov lus qhia thiab cov txheej txheem tsim nyog, cov pa oxygen kho mob tuaj yeem siv tau zoo thiab muaj txiaj ntsig los txhim kho cov txiaj ntsig ntawm tus neeg mob.
