Ib oximeter yog ib qho cuab yeej uas tawm lub teeb liab thiab infrared, ci los ntawm lub txaj capillary (feem ntau hauv lub ntsis ntiv tes lossis pob ntseg) mus rau lub sensor (Daim duab 1, txuas nrog). Ntau qhov ntsuas tau ua txhua ob thiab qhov piv ntawm liab rau lub teeb infrared yog xam los txiav txim qhov peripheral oxygen saturation (SpO2).
Koj ua li cas sau tus mem tes oximetry?
Thaum lub sijhawm nyeem ntawv pulse oximetry, ib qho khoom siv me me zoo li muab tso rau ntawm tus ntiv tes, pob ntseg, lossis ntiv taw. Cov kab me me ntawm lub teeb hla dhau cov ntshav ntawm tus ntiv tes, ntsuas cov pa oxygen. Nws ua qhov no los ntawm kev ntsuas kev hloov pauv ntawm lub teeb nqus hauv cov ntshav oxygenated lossis deoxygenated ntshav. Nov yog txheej txheem tsis mob.
Koj ua li cas sau cov pa oxygen saturation?
Thaum ntsuas los ntawm pulse oximeter, cov pa oxygen ib txwm nyob nruab nrab ntawm 95-100%. O2 sat tus nqi qis dua 90% suav tias yog qis. [1] Thaum ntsuas los ntawm arterial ntshav kuaj roj, ib qho kev noj qab haus huv O2 saturation feem ntau yog nyob nruab nrab ntawm 75-100 mm Hg.
Dab tsi yog 2 kev nyeem ntawm lub pulse oximeter?
Nws qhia ob qhov kev nyeem tseem ceeb: tus mem tes, kaw raws li neeg ntaus ib feeb thiab cov pa oxygen saturation ntawm hemoglobin hauv cov hlab ntsha. Qhov kev nyab xeeb ntawm tus mem tes yog hais tias nyob nruab nrab ntawm 60 mus rau 100. Thaum qhov kev nyeem ntawv ib txwm rau cov pa oxygen yog li ntawm 95% mus rau 100%.
Puas oxygen qib 93 phem?
Koj cov ntshav oxygen qib ntsuas yog feem pua-95 txog 100feem pua yog suav tias yog ib txwm. "Yog tias cov pa oxygen qis dua 88 feem pua, uas yog qhov ua rau muaj kev txhawj xeeb," said Christian Bime, MD, tus kws kho mob tshwj xeeb nrog kev tsom mus rau pulmonology ntawm Banner - University Medical Center Tucson.

Handcuffs yog ib feem loj ntawm fantasy football, tshwj xeeb tshaj yog thaum sau koj daim ntawv teev npe. Yog hais tias koj tsim ib qho kev raug mob hnyav khiav rov qab, thov xav txog kev sau nws cov thaub qab. Los yog, zoo dua, koj tuaj yeem nyiag koj cov phooj ywg sib koom tes tes.
Vim li cas pulse oximetry tsis raug?
Ntau yam tuaj yeem cuam tshuam qhov tseeb ntawm pulse oximeters, suav nrog kev ncig tsis zoo, tawv nqaij kub, tawv nqaij tuab, kev haus luam yeeb tam sim no, siv cov ntiv tes pleev xim, thiab xim tawv nqaij tsaus, FDA tau hais. Cov ntawv ceeb toom tsis ntev los no tau pom tias cov neeg mob dub yuav tsis tau txais kev nyeem ntawv tseeb los ntawm qee qhov oximeters.
Yuav tsum apical thiab radial mem tes zoo ib yam?
Ob tus lej no yuav tsum yog tib yam, uas txhais tau hais tias ib txwm apical-radial pulse yog xoom. Txawm li cas los xij, thaum ob tus lej sib txawv, nws yog hu ua pulse deficit. Pulse deficit yuav qhia tau tias mob plawv hu ua atrial fibrillation (A-fib).
Vim li cas aortic regurgitation dav mem tes siab?
Nyob rau hauv cov chav kawm ntawm regurgitant aortic valve kab mob, muaj nce loj hauv sab laug ventricular kawg-diastolic siab thiab sab laug atrial siab. Lub ventricle thiab atria muaj nuj nqi ntawm ib feem ntawm lawv cov kev ua raws txoj kab nkhaus kom lub ntim nce ua rau lub siab loj.
Kuv puas yuav raug them rau kev tsiv mus rau mtn mem tes?
Kuv yuav raug nqi npaum li cas rau kev tsiv mus rau MTN Pulse? A. Kev tsiv mus rau Pulse yog dawb. Txawm li cas los xij, yog tias nws yog koj qhov kev tsiv teb tsaws chaw tom ntej hauv 30 hnub ces koj yuav raug them ₦102. MTN nqi npaum li cas rau kev tsiv teb tsaws?
