Cov pa oxygen li qub yog kwv yees li 75 txog 100 hli ntawm mercury (hli Hg). Cov nqi qis dua 60 mm Hg feem ntau qhia tias xav tau cov pa oxygen ntxiv. Kev nyeem ntawv mem tes oximeter feem ntau yog li ntawm 95 txog 100 feem pua . Cov txiaj ntsig qis dua 90 feem pua suav tias yog qis.
Ua raws li qhov no, qhov kev nyab xeeb ntawm cov pa oxygen hauv cov ntshav yog dab tsi?
Normal: Ib txwm ABG qib oxygen rau lub ntsws noj qab nyob zoo poob ntawm 80 thiab 100 mm ntawm mercury (mm Hg). Yog ib tug pulse ox ntsuas koj ntshav oxygen qib (SpO2), kev nyeem ib txwm yog feem ntau ntawm 95 thiab 100 feem pua.
Tsis tas li ntawd, puas yog qib oxygen ntawm 97 zoo? Qhov qub oxygen saturation qib yog 97 –100% (OER #1). Cov neeg laus dua feem ntau muaj qis dua oxygen saturation qib dua cov laus. Piv txwv li, ib tus neeg laus dua 70 xyoo tuaj yeem muaj oxygen saturation qib txog li 95%, uas yog qhov siv tau qib.
Puas yog qib oxygen ntawm 94 phem?
Ib thaj tsam ntawm 94 -99% yog ib txwm rau cov neeg laus noj qab haus huv ua pa hauv chav uas muaj 21% oxygen . Leej twg tsis ua tiav qhov tseem ceeb ntshav oxygen saturation qib ntawm 90% (SpO2) lossis 55-60mmHg (SaO2), yuav xav tau ntxiv oxygen.
Dab tsi ua rau qis oxygen saturation hauv cov ntshav?
Ntau yam xwm txheej thiab qhov xwm txheej tuaj yeem cuam tshuam nrog lub cev muaj peev xwm xa tawm ib txwm muaj qib ntawm oxygen mus rau ntshav . Qee qhov feem ntau ua ntawm hypoxemia suav nrog: mob plawv, suav nrog lub plawv tsis xws luag. Mob ntsws xws li mob hawb pob, mob ntsws, thiab mob ntsws.
