Muviri unochengeta sei zvakajairika SpO2 mazinga?Kuchengeta yakajairika ropa oxygen saturation kwakakosha kudzivirira hypoxia.Nenzira yakanaka, muviri unowanzoita izvi uri woga.Nzira inonyanya kukosha yekuti muviri uchengetedze hutanoSpO2mazinga ari kuburikidza nekufema.Mapapu anotora okisijeni inenge yafemerwa oisunga kuhemoglobin, uyezve hemoglobin inofambiswa nemuviri pamwe chete neokisijeni.Pakushushikana kwemuviri kwakanyanya (sekusimudza masimbi kana kumhanya) uye kumusoro, kudiwa kweokisijeni kunowedzera.Chero bedzi ivo vasina kunyanya kunyanyisa, muviri unowanzokwanisa kugadzirisa kune izvi zvinowedzera.
Kuyera kuzara kweokisijeni muropa
Pane nzira dzakawanda dzekuyedza ropa kuti uve nechokwadi chekuti rine mwero weokisijeni wakajairwa.Nzira yakajairika ndeye kushandisa pulse oximeter kuyera mazinga eSpO2 muropa.Pulse oximeters iri nyore kushandisa uye yakajairika mumasangano ekurapa nemhuri.Pasinei nemutengo wavo wakaderera, iwo akarurama kwazvo.Kuti ushandise pulse oximeter, ingoiisa pamunwe wako.A percentage icharatidzwa pachiratidziri.Nhamba yacho inofanira kuva pakati pe94% ne100%, iyo inoratidza kuti hemoglobin inotakura okisijeni kuburikidza neropa iri pahutano hwakanaka.Kana iri pasi pe90%, unofanira kuona chiremba.
Ko pulse oximeter inoyera sei okisijeni muropa
Iyo pulse oximeter inoshandisa sensonzi yakareruka kunyora kuti ropa rakawanda sei rinotakura okisijeni uye kuti rakawanda sei ropa risingatakure oxygen.Oxygen-saturated hemoglobin inotaridzika kupenya kutsvuku kune ziso rakashama pane isiri-oxygen-saturated hemoglobin.Ichi chiitiko chinogonesa iyo yakanyanya kunzwa sensor ye pulse oximeter kuona shanduko diki muropa uye nekuishandura kuita kuverenga.
Kune akati wandei zviratidzo zvinowanzoitika zve hypoxemia.Nhamba uye kuoma kwezviratidzo izvi zvinoenderana nehuwandu hweSpO2.Moderate hypoxemia inogona kukonzera kuneta, dzungu, chiveve, uye kunzwa kurira mumakumbo uye kusvotwa.Kupfuura iyi pfungwa, hypoxemia inowanzova hypoxic.
Normal SpO2 mazinga akakosha kuchengetedza hutano hwese matishu ari mumuviri.Sezvambotaurwa, hypoxemia yakaderera oksijeni saturation muropa.Hypoxemia yakanangana ne hypoxia, inova iyo yakaderera oksijeni saturation mumatishu emunhu.Kana iyo okisijeni yemukati yakaderera zvakanyanya, hypoxemia inowanzo tungamira ku hypoxia, uye inoramba iri mune iyi mamiriro.Yakadzika yepepuru-tsvuku chiratidzo chakanaka che hypoxemia ichiva hypoxic.Zvisinei, haina kuvimbika zvachose.Semuenzaniso, vanhu vane ganda rakasviba havazove nepepuru osis iri pachena.Kana hypoxia ikawedzera, yepepuru yan syndrome kazhinji inotadza kuvandudza kuoneka.Nekudaro, zvimwe zviratidzo zve hypoxia zvinova zvakanyanya.Hypoxia yakakomba inogona kukonzera kugwinha, kuvhiringika, kuona zvinhu zvisiri izvo, kupenya, kurova kwemoyo zvisina kujairika uye pakupedzisira kufa.Hypoxia kazhinji inoburitsa snowball mhedzisiro, nekuti kana maitiro atanga, anomhanyisa uye mamiriro acho anokurumidza kuwedzera.Mutemo wakanaka wegunwe ndewekuti kana ganda rako richingotanga kutora bluish tint, iwe unofanirwa kutsvaga rubatsiro nekukurumidza.
