Kev tshawb nrhiav niaj hnub no qhia tau hais tias cov pa oxygen yog ib qho tseem ceeb rau kev kho mob ntawm cov ntshav qab zib, vim yog:
* Cov pa oxygen yog qhov nce ntawm cov pa roj ntshav, aerobic metabolism, noj qabzib ntau ntxiv, ntshav qabzib tuaj yeem txo;
* Cov pa tsis haum yuav ua rau lub cev qhov aerobic metabolism hauv lub cev, ua rau cov qoob loo ntawm adenosine triphosphate, thiab yuav pab txhawb txoj kev lag luam rov qab;
* Cov pa tsis haum yuav ua rau cov roj oxygen nyob rau hauv cov ntshav ntxiv, nce cov pa oxygen uas tau xa mus rau ntau qhov chaw hauv lub cev, cov ntaub so ntsiag to khov, thiab txo cov teeb meem los ntawm hypoxia.
Muaj cov kws soj ntsuam cov neeg uas nqus pa hauv cov pab pawg neeg mob ntshav qab zib thiab pom cov kev hloov hauv ntshav qabzib thiab zis glucose tom qab nqus pa. Cov neeg mob ua rau lub cev tsis muaj zog tshaj li ntawm 90% ntawm cov pa tshuaj oxygen 2-4 zaug ib hnub twg 1-2 teev, qhov ntsuas qhov ntsuas yog 2L / feeb, tom qab peb lub lis piam ntawm kev soj ntsuam, ntshav qabzib, zis muaj piam thaj hauv qab tau qis qee dua Qee tus tseem rov qab mus rau qhov qub, thiab cov tsos mob kuj raug txo kom tsawg. Tsis muaj kev mob tshwm sim los ntawm kev siv mus sij hawm ntev.
