Cov pa luam yeeb carbon monoxide ua rau mob li cas?
Cov pa roj carbon monoxide (CO) yog ib qho muaj roj, tsis muaj xim, thiab tsis muaj roj tsw qab uas ua thaum tsis muaj cov hlawv roj uas tsis muaj roj hlawv. Nws nyob rau hauv tshav dav hlau sab hauv tsev thiab sab nraum cov khoom siv xws li tsheb tsheb, qhov cub qhov muag, cov qhov cub hluav taws, qhov cub tawg thiab pa luam yeeb , uas muaj peev xwm muaj cov roj carbon monoxide siab.
Carbon Monoxide nyob rau hauv tib neeg lub cev
Thaum carbon monoxide ua pa rau hauv lub ntsws, nws khi nrog hemoglobin nyob rau hauv cov ntshav liab kom ua carboxyhemoglobin (COHb) uas yog thauj mus rau hauv cov hlab ntsha.
Thaum qhov no tshwm sim, cov pa oxygen tsis khi nrog cov phom sij ntawm tib lub cell. Thiab vim tias CO muaj kev ceev nrooj ntau dua ntawm kev siv cov hemoglobin dua oxygen (kwv yees li 200 npaug sai dua), thaum CO muaj nyob rau hauv lub ntsws, nws yeej qhov chaw ntawm cov ntshav liab. Qhov txheej txheem no ua rau cov pa oxygen muaj peev xwm nyob hauv cov hlab ntsha.
Cov pa roj carbon monoxide yog ceev nrig nrog cov qe ntshav liab, tiam sis qeeb tawm hauv lub cev, noj ntau npaum li ib hnub twg yuav tsum tau ua pa ntawm lub ntsws.
Ib qho kev nplua nuj ntawm carbon monoxide nyob rau hauv cov hlab ntsha tshaib plab hauv lub cev ntawm oxygen thiab nyob rau hauv feem ntau qhov phem, muaj peev xwm ua rau tuag.
Carbon Monoxide nyob rau hauv lub haus luam yeeb lub cev
Lub cev theem ntawm COHb nyob rau hauv cov hlab ntsha ntawm thaj tsam raug carbon monoxide yog tsawg dua ib feem pua.
Rau cov neeg haus luam yeeb, yam zoo li hom, luam yeeb ntau npaum li cas thiab cov sijhawm ntawm cov luam yeeb yuav ua rau COHb tsis txaus siab nyob rau hauv cov ntshav kom ntau dua. Ib pob ntim khoom haus ib hnub yog 3% mus rau 6% COHb theem hauv cov ntshav, ob pob rau ib hnub, 6% txog 10%, thiab peb pob rau ib hnub twg, ntau li 20%.
Qhov teebmeem ntawm kev mob CO hauv cov ntshav siab tshaj 1% tuaj yeem ua rau pom kev zoo ntawm lub cev, xws li:
- Ua rau lub plawv dhia ntawm 1% mus rau 5%.
- Txo kev txo kom qis ib ce rau ib ce ntawm 2% mus rau 15%.
- Kev mob taub hau thiab kev sib thooj hauv kev sib txawv tuaj yeem tshwm sim nyob rau theem siab ntawm CO co - ntawm 15% mus rau 20%.
Tsis muaj oxygen hauv hlwb kuj ua rau lub plawv ua hauj lwm nyuab kom faib cov pa oxygen nyob ib ncig ntawm lub cev, ua CO yog ib qho loj contributor rau kab mob hauv lub plawv, xws li plawv nres thiab atherosclerosis .
Cov pa luam yeeb ntawm lwm tus kuj tseem muaj cov qib CO, cov neeg haus luam yeeb uas ua pa hauv ETS tuaj yeem muaj theem CO ntau ntxiv hauv lawv cov ntshav.
Puas Muaj Kev Haus Luam Yeeb Ua Ntej Cov Tshuaj Lom Cov Tshuaj Tiv Thaiv Carbon Monoxide?
Tau, nws muaj peev xwm raug kev mob CO tawm ntawm kev haus luam yeeb yog tias muaj coob tus luam yeeb haus luam yeeb nyob rau hauv qhov chaw nkag. Rau feem ntau cov neeg haus luam yeeb txawm, cov tsos mob ntawm CO ntau hauv lawv cov ntshav, zoo li lub plawv dhia, mob taub hau, thiab xeev siab yuav ua rau lawv mob siab thiab ua kom lawv qeeb ntawm cov haus luam yeeb kom txaus tsis xav tau kev pab kho mob.
Hauv ib qhov xwm txheej loj heev, tus poj niam tau taug kev mus rau chav xwm txheej ceev ntawm nws lub tsev kho mob vim nws xav tias nws lub taub hau thiab mob taub hau. Cov ntshav ua haujlwm tau qhia tias muaj roj carbon dioxide nyob rau hauv nws cov ntshav. Nws lub tsev tau ntsuam xyuas rau cov pa carbon monoxide thiab tsis pom muaj.
Ib lub lim tiam tom qab ntawd nws rov qab rau hauv tsev kho mob nrog tib cov tsos mob. Lub sij hawm no, carbon monoxide nyob rau hauv nws cov ntshav yog ze li 25 feem pua. Nws tsis xav tias nws xav zoo li phem. Nws yog ib tug hnyav haus ntawm ntau tshaj ob pob rau hauv ib hnub thiab tau haus luam yeeb ntau heev hauv ib lub sijhawm luv luv.
Tus kws kho mob tau kho nws nrog cov pa thiab nws tau zoo, tab sis txoj kev daws teebmeem nws qhov teebmeem rau lub sijhawm ntev tau txiav luam yeeb.
Cov tsos mob ntawm Carbon Monoxide Poisoning
Cov pa roj carbon monoxide ua kom qis tsis muaj peev xwm ua rau:
- nkees
- nce hauv siab mob hauv cov neeg uas mob plawv
Hauv kev noj qab haus huv tib neeg, kev nqus cov pa carbon monoxide ntau dua tuaj yeem ua rau cov tsos mob ua npaws (tsis muaj kubcev) xws li:
- mob taub hau
- kiv taub hau
- tsis muaj zog
- tsaug zog
- xeev siab
- ntuav
- tsis meej pem
- tsis ua haujlwm
Nyob rau theem siab heev, raug carbon monoxide yuav ua rau tsis nco qab thiab tuag, yog li nws yog qhov tseem ceeb uas yuav tsum tau nrhiav kev kho mob yog tias koj muaj cov tsos mob saum toj no.
Ib lo lus los ntawm
Cov pa nkev no tsuas yog ib qho ntawm ntau cov tshuaj hauv cov pa luam yeeb.
Txog hnub tim, ntau tshaj li 7,000 cov tshuaj lom neeg, 250 uas paub tias yog lom thiab nce siab tshaj 70 uas tau raug txheeb xyuas tias yog cov carcinogens uas paub tias nyob hauv luam yeeb.
Yog koj tseem haus luam yeeb, siv cov ntaub ntawv no los pab koj kom koj txiav txim siab txiav tawm tam sim no. Cov kev pab hauv qab no yuav pab koj pib.
Tsis txhob ntshai haus luam yeeb . Lwm tus tau ua tiav nws. Koj tuaj yeem tau.
