Ropa oxygen saturation chimwe chezviratidzo zvakakosha zvehutano hwemuviri.Kuzadzwa kweokisijeni yeropa revanhu vane hutano hwakanaka kunofanirwa kuchengetwa pakati pe95% ne100%.Kana yakaderera kupfuura 90%, yakapinda mumhando ye hypoxia.% ndiyo yakanyanya hypoxia, iyo inokonzeresa kukuvadzwa kukuru kumuviri uye kuisa hupenyu panjodzi.
Ropa okisijeni saturation chinhu chakakosha physiological parameter inoratidza kufema uye circulatory basa.Zvinoenderana nehuwandu husina kukwana, mazhinji ezvikonzero zvekukurumidzira kubvunzana nemadhipatimendi ekufema mumadhipatimendi akakodzera muzvipatara zvine chekuita neokisijeni yeropa.Isu tese tinoziva kuti yakaderera oksijeni saturation haiparadzaniswe kubva kuzvirwere zvekufema, asi hazvisi zvese zvinodzikira muropa oxygen saturation inokonzerwa nezvirwere zvekufema.
Ndezvipi zvikonzero zvekuderera kweokisijeni muropa?
1. Kana chidimbu chekumanikidzwa kweokisijeni yakafemeswa yakadzikira.Kana iyo okisijeni yakafemerwa isina kukwana, kuzara kweokisijeni kunogona kuderera.Zvichisanganiswa nenhoroondo yezvokurapa, murwere anofanira kubvunzwa kana akamboenda kunzvimbo dzakafara dziri pamusoro pe3000m, kubhururuka kwepamusoro-soro, kukwira mushure mekunyura, uye migodhi isina kufema zvakanaka.
2. Kana paine kuvharika kwemhepo.Izvo zvinodiwa kuti utarise kana paine chinovharira hypoventilation chinokonzerwa nezvirwere zvakaita seasthma, COPD, kudonha kwemidzi yerurimi, uye kuvharika kwemuviri wekunze kwekubuda kwekufema.
3. Kana paine kusashanda kwemhepo.Zvakakosha kufunga kana murwere ane mabayo akanyanya, tibhii yakanyanya, diffuse pulmonary interstitial fibrosis, pulmonary edema, pulmonary embolism uye zvimwe zvirwere zvinokanganisa basa remhepo.
4. Ndeupi hutano uye huwandu hweHb inotakura oksijeni muropa.Kuonekwa kwezvinhu zvisina kujairika, senge CO poisoning, nitrite poisoning, uye kuwedzera kukuru kwehemoglobin isina kujairika, haisi kungokanganisa zvakanyanya kutakurwa kweokisijeni muropa, asiwo inokanganisa zvakanyanya kuburitswa kweokisijeni.
5. Kana murwere ane yakakodzera colloid osmotic pressure uye uwandu hweropa.Yakakodzera colloid osmotic pressure uye huwandu hweropa hwakakwana ndechimwe chezvinhu zvakakosha kuchengetedza yakajairika oxygen saturation.
6. Chii chinobuda pamwoyo wemurwere?Kuchengetedza kuendeswa kweokisijeni kunhengo kunofanirwa kutsigirwa nemoyo wakakwana.
7. Tissue uye organ microcirculation.Kugona kuchengetedza okisijeni yakakodzera kunoenderanawo nemetabolism yemuviri.Kana metabolism yemuviri yakakurisa, iyo venous yeropa okisijeni yemukati inodzikiswa zvakanyanya, uye ropa re venous rinotungamira kune yakanyanya kuoma hypoxia mushure mekupfuura nepakati peiyo shunted pulmonary circulation.
8. Kushandiswa kweokisijeni mumasumbu akapoteredza.Matishu anogona kushandisa okisijeni yemahara chete, uye okisijeni yakasanganiswa neHb inogona kushandiswa chete nematishu kana yaburitswa.Kuchinja kwepH, 2,3-DPG, nezvimwewo kunokanganisa kuparadzaniswa kweokisijeni kubva kuHb.
9. Simba rekurova.Oxygen saturation inoyerwa zvichienderana nekushanduka kwekunyura kunoitwa ne arterial pulsation, saka transducer inofanira kuiswa panzvimbo ine pulsating blood.Chero zvinhu zvinonetesa kuyerera kweropa, sekukurudzira kutonhora, kunzwira tsitsi tsinga kufara, chirwere cheshuga uye varwere vane arteriosclerosis, zvinoderedza kuyerwa kwechiridzwa.SpO2 haigone kuonekwa kunyangwe kune varwere vane cardiopulmonary bypass uye kusungwa kwemoyo.
