Thaum xyoo 1990s lig, ntau qhov kev tshawb fawb tau ua los ntsuas qhov tseeb ntawm cov neeg tsis yog kws tshaj lij, cov neeg teb thawj zaug, kws kho mob thiab txawm tias kws kho mob hauv kev tshuaj xyuas tsuas yog muaj cov mem tes.Hauv ib txoj kev tshawb fawb, qhov ua tiav ntawm kev paub txog mem tes yog tsawg li 45%, thaum nyob rau hauv lwm txoj kev tshawb fawb, cov kws kho mob me tau siv qhov nruab nrab ntawm 18 vib nas this kom paub txog mem tes.
Nws yog vim li no, raws li cov lus pom zoo ntawm Pawg Neeg Sawv Cev Hauv Ntiaj Teb, Pawg Neeg Sawv Cev Hauv Tebchaws Askiv thiab American Heart Association tau tso tseg tsis tu ncua kev kuaj mem tes raws li lub cim ntawm lub neej los ntawm kev cob qhia thawj zaug hloov kho xyoo 2000.
Tab sis kev tshuaj xyuas cov mem tes yog qhov tseem ceeb heev, Raws li nrog tag nrho cov cim tseem ceeb, paub seb tus neeg mob lub plawv dhia puas nyob hauv qhov qub tuaj yeem xa cov ntaub ntawv tseem ceeb rau peb;
Yog tias cov mem tes ntawm cov neeg raug mob tsis nyob hauv cov kab no, nws tuaj yeem ua rau peb muaj teeb meem tshwj xeeb.Yog tias ib tug neeg khiav ncig, peb cia siab tias lawv cov mem tes yuav nce.Peb kuj xav kom lawv kub, liab thiab ua pa sai.Yog tias lawv tsis tau khiav ncig, tab sis kub, liab, ua tsis taus pa thiab mem tes ceev, peb yuav muaj teeb meem, uas yuav qhia tau tias sepsis.Yog tias lawv raug mob;kub, liab, qeeb thiab muaj zog mem tes, qhov no yuav qhia tau tias muaj kev raug mob taub hau.Yog tias lawv raug mob, txias, daj ntseg thiab muaj lub plawv dhia ceev, lawv yuav muaj kev poob siab hypovolemic.
Peb yuav siv pulse oximeter:Pulse oximeteryog ib qho kev kuaj mob me me uas tsuas yog siv los txheeb xyuas cov ntshav oxygen saturation ntawm cov neeg raug mob, tab sis nws kuj tuaj yeem pom cov mem tes ntawm cov neeg raug mob.Nrog ib tug ntawm lawv, peb tsis tas yuav nkim sij hawm mus cuag cov neeg raug mob thiab xav tias ib tug throbbing desperately.
Txoj kev pulse oximetry ntsuas cov pa oxygen nqa hauv cov ntshav raws li feem pua.Siv lub mem tes oximeter ntsuas ntawm koj tus ntiv tes.Qhov ntsuas no hu ua Sp02 (peripheral oxygen saturation), thiab yog kwv yees ntawm Sp02 (arterial oxygen saturation).
Lub hemoglobin hauv cov qe ntshav liab nqa oxygen (ib qho me me yog yaj hauv cov ntshav).Txhua hemoglobin molecule tuaj yeem nqa 4 oxygen molecules.Yog tias tag nrho koj cov hemoglobin raug khi rau plaub lub molecules oxygen, ces koj cov ntshav yuav "saturated" nrog oxygen, thiab koj SpO2 yuav yog 100%.
Cov neeg feem coob tsis muaj 100% oxygen saturation, yog li qhov ntau ntawm 95-99% suav tias yog qhov qub.
Txhua qhov ntsuas qis dua 95% tuaj yeem qhia tau tias hypoxia-hypoxic oxygen yuav nkag mus rau cov ntaub so ntswg.
Kev txo qis hauv SpO2 yog qhov pom tseeb tshaj plaws ntawm tus neeg raug mob hypoxia;Kev nce hauv kev ua pa yog cuam tshuam nrog hypoxia, tab sis muaj pov thawj tias qhov kev sib txuas no tsis muaj zog txaus (thiab txawm tias muaj nyob rau hauv txhua rooj plaub) los ua lub cim ntawm hypoxia.
Covmem tes oximeteryog cov cuab yeej kuaj mob ceev uas tso cai rau koj ntsuas thiab saib xyuas cov pa oxygenation ntawm cov neeg raug mob.Paub tias Sp02 raug mob kuj tuaj yeem pab koj muab cov pa oxygen txaus hauv qhov kev txawj ntse.
Txawm hais tias cov ntshav oxygen saturation nyob rau hauv qhov ib txwm muaj, SpO2 raug txo los ntawm 3% lossis ntau dua, uas yog qhov qhia rau kev ntsuas ntau dua ntawm tus neeg mob (thiab oximeter teeb liab), vim tias qhov no yuav yog thawj qhov pov thawj ntawm tus kab mob hnyav.
