Vim li cas cov pa roj carbon dioxide hauv tsev yuav tsum tau saib xyuas online?
Nyob rau hauv cov ntaub ntawv ntawm lub tsev Blue House nyob rau hauv tsev ib puag ncig saib xyuas, ntau cov neeg muas zaub yuav ntsib xws li cov teeb meem nrog cov pa roj carbon dioxide xyuas: qhov concentration kuv ntes nyob rau hauv tsev yog tej zaum nyob ib ncig ntawm 500ppm, thiab tej zaum nws yuav ncav cuag ib ncig ntawm 1200ppm thaum nws siab. Qhov no puas yog ib txwm? Cov concentration ntau npaum li cas yuav ua rau tib neeg lub cev? Hauv qab no, Lanju yuav teb cov lus nug ntsig txog carbon dioxide hauv kev saib xyuas ib puag ncig sab hauv tsev.
Qhov ceev ntawm cov pa roj carbon dioxide yog siab dua li huab cua. Thaum muaj cov pa roj carbon dioxide tsawg dua, nws tsis muaj kev phom sij rau tib neeg lub cev, tab sis thaum nws tshaj li qee qhov, nws yuav cuam tshuam rau kev ua pa ntawm tib neeg (thiab lwm yam kab mob). Yog vim li cas yog qhov concentration ntawm carbonic acid nyob rau hauv cov ntshav nce, acidity nce, thiab acidosis tshwm sim. Thaum qhov ntim feem ntawm cov pa roj carbon dioxide nyob hauv huab cua yog 1 feem pua, koj yuav hnov qhov khaus, kiv taub hau, thiab palpitations; thaum nws yog 4 feem pua -5 feem pua, koj yuav xav tias kiv taub hau. Thaum nws siab tshaj 6 feem pua, nws yuav ua rau tib neeg tsis nco qab, ua pa yuav maj mam nres thiab ua rau tuag.
Vim tias cov pa roj carbon dioxide hnyav dua li huab cua, cov ntsiab lus siab dua hauv qhov chaw qis. Thaum cov neeg ua haujlwm hauv lub qhov dej los yog khawb pawg, qhov cua tsis zoo yuav ua rau cov neeg nyob hauv qab ntawm qhov dej. Cov ntsiab lus ntawm CO? yog 0.04 feem pua . Thaum twg cov concentration ntawm CO? nce mus txog 1 feem pua, tib neeg yuav hnov ua tsis taus pa, kiv taub hau, thiab plawv dhia. Thaum nws nce mus txog 4% ~ 5 feem pua, tib neeg yuav hnov mob hawb pob, mob taub hau, thiab kiv taub hau. Qee zaum, nws yuav ua rau muaj kev tsis sib haum xeeb loj hauv kev ua haujlwm ntawm tib neeg lub cev, ua rau tib neeg tsis nco qab, tsis nco qab, tsis ua pa thiab tuag. Cov tshuaj kom zam:
Ntau yam hlau plua plav (xws li magnesium, zirconium, titanium, aluminium, manganese): yooj yim ignite thiab tawg thaum raug tshem tawm hauv carbon dioxide. Dej: Carbonic acid yog tsim.
Coma thiab cerebral hypoxia tshwm sim thaum tib neeg nqus tau cov pa roj carbon dioxide siab. Feem ntau, thaum cov ntsiab lus carbon dioxide nyob rau hauv qhov chaw siab tshaj 1 feem pua, tib neeg yuav muaj cov tshuaj tiv thaiv kiv taub hau; thaum nws tshaj 3 feem pua, lawv pib ua pa nyuaj; Mob hypoxia suffocation thiab txawm tuag yuav tshwm sim.
Qhov concentration ntawm carbon dioxide yuav cuam tshuam rau lub neej niaj hnub ntawm tib neeg. Cov concentration ntawm carbon dioxide thiab cov lus teb physiological ntawm tib neeg lub cev yog txheeb tawm raws li hauv qab no:
·350-450ppm: Ib yam li qhov chaw sab nraum zoov
·350-1000ppm: huab cua ntshiab thiab ua pa du.
1000-2000ppm: xav tias huab cua turbid, thiab pib tsaug zog.
· 2000-5000ppm: mob taub hau, tsaug zog, qaug zog, tsis muaj peev xwm mloog tau, lub plawv dhia ceev, xeev siab me ntsis.
Ntau tshaj 5000ppm: Tej zaum yuav ua rau mob hypoxia, lub hlwb puas tsuaj mus tas li, coma, lossis tuag taus.
Cov ntsiab lus ntawm CO? kuaj pom nyob rau hauv cov ntshav (plasma) yog ib qho ntawm cov cim qhia ntawm nruab nrab metabolic acid-base, uas ib txwm sawv cev rau lub xeev ntawm acid-base cia nyob rau hauv plasma.
Reactions rau carbon dioxide lom
Cov tsos mob tseem ceeb yog: mob taub hau, kiv taub hau, tinnitus, ua tsis taus pa luv, hauv siab nruj, qaug zog, lub plawv dhia ceev, cyanosis ntawm lub puab tsaig, chim siab, delirium, dyspnea, thiab yog tias qhov teeb meem tshwm sim, lethargy, apathy, coma, poob ntawm reflexes, dilated tub kawm mob plab, incontinence, ntshav siab poob thiab txawm tuag.
Thaum lub concentration ntawm carbon dioxide nce mus txog ntau tshaj 1 feem pua, cov neeg yuav xav tias kiv taub hau. Thaum nws nce mus txog 4-5 feem pua, tib neeg yuav raug xeev siab thiab ntuav, thiab ua pa nyuaj. Ntau tshaj 10 feem pua, tib neeg yuav tuag.
Cov cuab yeej ntsuas cua sab hauv tsev tau siv dav hauv cov tsev ua haujlwm, chav tsev kawm ntawv, cov zej zog thiab lwm qhov chaw. U-MINI ntse me me ib puag ncig saib xyuas lub davhlau ya nyob twg, cov khoom lag luam tau txais kev siv thev naus laus zis thev naus laus zis, los ntawm cov khoom siv hauv microprocessor, ntes thiab sab hauv cov khoom siv suav nrog, nws tuaj yeem ua tiav cov khoom sau, suav thiab txheeb xyuas cov huab cua ntawm ib puag ncig sab nraud. Saib xyuas PM2.5, PM10, kub thiab av noo, carbon dioxide, formaldehyde thiab lwm yam roj thiab cov khoom kom ua tiav cov txiaj ntsig zoo ntawm kev saib xyuas ib puag ncig
Cov cuab yeej ntsuas huab cua sab hauv tsev muaj ob txoj kev xa cov ntaub ntawv: wireless thiab wired; nws suav nrog cov cim qhia ua haujlwm; nws muaj kev ceeb toom ntxov thiab kev kwv yees ua haujlwm. U-MINI sab hauv tsev huab cua zoo saib xyuas lub davhlau ya nyob twg yog qhov me me, lub teeb hauv qhov hnyav, tsis muaj zog siv, me me hauv qhov chaw, thiab yooj yim rau nruab. Nyob rau tib lub sijhawm, cov neeg siv tuaj yeem tshawb xyuas cov ntaub ntawv tshawb pom huab cua sab hauv tsev tam sim no txhua lub sijhawm los ntawm lub xov tooj ntawm tes APP tus neeg siv nws tus kheej tsim los ntawm Lanju, txhawm rau nkag siab cov huab cua hauv tsev zoo dua intuitively. Lub WeChat cov kev pabcuam tus account hloov kho cov ntaub ntawv synchronously, ua cov ntaub ntawv thoob plaws thiab cov ntaub ntawv ib kauj ruam ua ntej.
