Ua qhov no hauv kev txiav txim siab, qis po2 txhais li cas?
Siab los yog qis qhov tseem ceeb qhia txog ntshav hyperoxia lossis hypoxia, feem. pO2 ua nyob rau hauv cov ntshav qis dua tshaj li cov ntshav arterial vim yog oxygen extraction los ntawm peripheral cov ntaub so ntswg. pCO2: Nws yog ntsuas siv pCO2 electrode. Nws yog lub siab ib nrab ntawm pCO2 nyob rau hauv ib theem roj nyob rau hauv equilibrium nrog cov ntshav.
Ib yam nkaus, PaO2 txhais li cas? Lub siab ib nrab ntawm oxygen, tseem hu ua PaO 2 , yog ib qho kev ntsuas ntawm oxygen siab hauv cov hlab ntsha.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov qub po2?
Piv txwv li, tus normal PO2 (ib nrab siab ntawm cov pa) yog 80? 100 mmhg. Tag nrho qhov no yuav tsum txhais tau tiag tiag rau peb yog tias hauv cov ntshav hlab ntsha, 80 mus rau 100 mmHg sawv cev rau "tus nqi" ntawm cov pa oxygen uas yaj hauv txhua 100 ml ntawm cov ntshav hlab ntsha. Tag nrho lossis ib qho ntawm cov xwm txheej no tuaj yeem ua rau qis PO 2.
Dab tsi yog PaO2 li qub?
Raws li National Institute of Health, ib txwm ib txwm muaj nuj nqis yog: pH: 7.35-7.45. Ib nrab siab ntawm oxygen ( PaO 2 ): 75-100 mmHg. Ib nrab siab ntawm carbon dioxide ( PaCO 2 ): 35-45 mmHg.

(Saib 'Techniques for lower extremity amputation'.) TERMINOLOGY. Kev txiav tawm loj yog hais txog ib qho kev txiav tawm uas tau ua tiav siab dua theem ntawm pob taws
Vim li cas qis qis qis dua muaj stomata ntau dua li daim tawv nqaij sab saud?
Piav qhia: Txhua qhov chaw ntawm nplooj ntoo muaj qee tus nqi ntawm stomata rau kev tswj cov pa pauv rau cov duab ci. Txawm li cas los xij, cov kab mob qis qis (sab hauv qab ntawm nplooj) muaj ntau dua, vim tias nws feem ntau nyob hauv qhov ntxoov ntxoo thiab yog li nws txias dua, uas txhais tau tias kev nqus dej yuav tsis tshwm sim ntau dua
