Dab tsi yog qhov ntsuas qhov ntsuas ntawm lub ntsuas pa oxygen?
Tej zaum koj txhua tus paub tias ib qho ntawm lub hom phiaj ntawm lub tshuab ntsuas pa oxygen yog kuaj kev nyab xeeb ntawm tib neeg lub cev rau hypoxia. Nws qhov ntsuas qhov ntau yog 0-30% vol ntsuas qhov ntau. Vim tias tib neeg lub cev kev nyab xeeb xav kom cov pa oxygen tsis tuaj yeem qis dua 19.5% vol, yuav tsum tau muab lub tswb. , koj yuav tsum tau ceeb toom yog tias cov pa oxygen-enriched concentration ntau tshaj 23% vol, vim hais tias cov pa-enriched oxygen tuaj yeem ua rau tib neeg lub cev tsis ua haujlwm zoo. Yog li, qhov kev ntsuas feem ntau siv yog 0-30%vol, thiab qee qhov kuj siv qhov ntau ntawm 0-25%vol. Qhov tseeb, lawv txhua tus yog tib yam, vim hais tias cov sensors sab hauv ntawm lub ntsuas pa oxygen txhua tus muaj qhov sib txawv. Qhov ntsuas qhov koj xaiv yog 0-25% lossis 0-30% vol, qhov tseeb yog tib yam. Nws raug nquahu kom xaiv 0-30%vol ncaj qha. Tau kawg, ntxiv rau cov pa oxygen hypoxia ceeb toom ua haujlwm uas feem ntau siv los ntsuas tib neeg kev nyab xeeb tau hais los saum toj no, muaj ntau lwm yam kev siv uas yuav tsum tau kuaj xyuas oxygen. Lub hom phiaj tshwj xeeb tseem ceeb suav nrog ob yam hauv qab no:
1. Txheeb xyuas cov pa oxygen ib puag ncig. Ntau cov pa oxygen cov ntsiab lus tau kuaj pom hauv cov pa roj carbon ntau. Piv txwv li, cov pa oxygen tau kuaj pom hauv cov pa ntshiab hydrogen thiab cov pa oxygen tau kuaj pom hauv cov nitrogen ntshiab. Cov no yog tag nrho cov taug qab oxygen detectors. Qhov ntau yog feem ntau yog 0-10000ppm. Nyob rau hauv lub ntim piv concentration ntau ntawm 1% vol.
2. Hauv cov ntawv thov uas kuaj pom cov pa oxygen siab siab, piv txwv li, qee qhov kev tswj hwm kev lag luam yuav tsum tau kuaj xyuas cov pa purity, lossis nrhiav kom pom cov pa oxygen uas tsim los ntawm lub tshuab hluav taws xob oxygen. Rau cov ntawv thov no, cov ntsiab lus oxygen yog qhov siab, yog li nws raug pom zoo kom xaiv 0-100% vol. ntsuas qhov ntau
Raws li cov ntawv thov kev lag luam saum toj no, kev ntsuas ntau ntawm oxygen detectors feem ntau muab faib ua peb pawg:
1) Tib neeg lub cev kev nyab xeeb thiab kev tiv thaiv hypoxia ntau qhov kev siv ntau: 0-30% vol ntau;
2) Tshawb nrhiav cov pa oxygen siv: 0-10000ppm;
3) High concentration ntsuas purity ntawm cov pa oxygen: 0-100% vol.
Qhov saum toj no peb tus qauv ntau yog cov khoom siv oxygen ntau yam.
