Cov lus piav qhia txog qhov tseem ceeb ntawm cov ntsuas pa oxygen hauv kev ua haujlwm hauv kev ua haujlwm
Cov pa roj oxygen, ua cov roj tshwj xeeb uas tswj hwm tib neeg lub neej lub neej, feem ntau yog tswj hwm ntawm kev sib haum xeeb ntawm 20.9% vol. Yog tias nws tshaj li 23% lossis poob qis dua 19%, nws yuav ua rau tib neeg lub cev, thiab muaj mob hnyav, nws yuav ua rau kev tuag.
Nyob rau hauv cov txheej txheem ntawm kev lag luam kev ua haujlwm, vim muaj tshwj xeeb ntawm kev ua haujlwm, nws yog ib qho chaw ua haujlwm hauv hypoxia thiab kev poob siab vim oxygen tsis txaus. Nyob rau hauv cov chaw uas muaj cov txheej txheem tshuaj lom neeg raug nqa tawm, cov oxygen me dhau los muaj qhov cuam tshuam rau cov txiaj ntsig, thiab muaj mob hnyav, nws yuav ua rau hluav taws lossis tawg. Yog li no, txhim kho cov pa oxygen kuj yog ua kom ntseeg tau cov pa yog nyob rau hauv lub xeev sib npaug rau qee yam.
Yog li dab tsi yuav tsum tau sau tseg thaum xaiv cov pa oxygen? Firstly, cov kev kuaj cov pa oxygen feem ntau muab faib ua cov pa oxygen thiab cov pa oxygen. Feem ntau, thaum nkag mus rau qhov chaw kaw lus, nws yog ib qho tsim nyog yuav tau nqa cov pa oxygen portable nrog koj rau oxygen nrhiav kom tsis txhob muaj oxygen tshwm sim los ntawm tsis muaj pa.
Nrhiav Hluav Taws Xob Hluav Taws Xob
Rau qee qhov kev cob qhia tawm tshiab, cov hlab ntsha cov nkoj, thiab lwm qhov chaw uas xav tau, cov neeg ua haujlwm configure, configure controllers kom cov neeg ua haujlwm tuaj yeem tau txais lub tswb ceeb toom kom raws sijhawm.
Dab tsi yog tus qauv rau cov pa ocentration Nrhiav tau tus nqi
Cov oxygen conctration nyob rau hauv ib puag ncig ib puag ncig yog 20.9% vol.
Nws yog ib qho tsim nyog los siv cov pa oxygen. Cov pa oxygen ib txwm muaj 20.9% vol. Thaum lub siab zoo nyob hauv qab 19.5% vol, nws suav tias yog hypebia. Thaum hypoxia tshwm sim, nws yog kev puas tsuaj rau tib neeg lub cev thiab kev nco qab kuj tseem tuaj yeem cuam tshuam. Thaum cov oxygen concenation yog ib yam nkaus, kev pheej hmoo ntawm kev sib txuas lossis tawg yog ntau dua.
