SpO₂ chimwe chezviratidzo zvakakosha zvehutano hwemuviri. Iyo SpO₂ yemunhu ane hutano hwakanaka inofanirwa kuchengetwa pakati pe95% -100%. Kana yakaderera kupfuura 90%, yakapinda mumhando ye hypoxia, uye kamwe yakaderera pane 80% % Ndiyo yakanyanya hypoxia, iyo inogona kukonzera kukanganisa kukuru kumuviri uye kuisa upenyu pangozi.

SpO₂ inokosha physiological parameter inoratidza kufema uye circulatory mabasa. Zvinoenderana nehuwandu husina kukwana, mazhinji ezvikonzero zvekubvunza nekukurumidza kwedhipatimendi rekufema mumadhipatimendi akakodzera echipatara ane hukama neSpO₂. Isu tese tinoziva kuti yakaderera SpO₂ haiparadzaniswe nedhipatimendi rekufema, asi kwete ese anoderera muSpO₂ anokonzerwa nezvirwere zvekufema.

Ndezvipi zvikonzero zvepasi SpO₂?

1. Kana chidimbu chekumanikidzwa kweokisijeni yakafemeswa yakadzikira. Kana iyo okisijeni yemukati yegasi yakafemerwa isina kukwana, inogona kukonzera kudzikira kweSpO₂. Maererano nenhoroondo yezvokurapa, murwere anofanira kubvunzwa kana akamboenda kunzvimbo dzakakwirira pamusoro pe3000m, achibhururuka pakakwirira, achikwira mushure mekunyura, uye migodhi isina kufema zvakanaka.

2. Kana paine kuvharika kwemhepo. Izvo zvinodiwa kuti utarise kana paine chinovharira hypoventilation chinokonzerwa nezvirwere zvakaita seasthma neCOPD, kudonha kwechigadziko cherurimi, uye kuvharika kwekunze kwemuviri wekunze mumhepo yekufema.

3. Kana paine kusashanda kwemhepo. Funga nezvekuti murwere ane mabayo akanyanya, tibhii yakanyanya, diffuse pulmonary fibrosis, pulmonary edema, pulmonary embolism uye zvimwe zvirwere zvinokanganisa basa rekufema.

4. Hb inotakura okisijeni muropa yakadii uye yakawanda sei? 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 colloid osmotic pressure yakakodzera uye uwandu hweropa. Yakakodzera colloidal osmotic pressure uye huwandu hweropa hwakakwana ndechimwe chezvinhu zvakakosha zvekuchengetedza yakajairika oxygen saturation.

6. Chii chinobuda pamwoyo wemurwere? Kuchengetedza yakajairika oxygen kuendeswa kwenhengo, panofanirwa kuve nemoyo wakakwana kubuda kuti utsigire.

7. Microcirculation yezvinyama uye nhengo. Kugona kuchengetedza okisijeni yakakodzera kunoenderanawo nemetabolism yemuviri. Kana metabolism yemuviri yakakurisa, iyo oxygen yemukati yeropa re venous inodzikiswa zvakanyanya. Mushure mekunge ropa re venous rapfuura nekutenderera kwepulmonary shunted, zvinokonzeresa yakanyanya hypoxia.

8. Kushandiswa kweokisijeni mumatishu akapoteredza. Tissue masero anogona chete kushandisa okisijeni munzvimbo yakasununguka, uye okisijeni yakasanganiswa neHb inogona kushandiswa chete nenyama kana yaburitswa. Kuchinja kwepH, 2,3-DPG, nezvimwewo kunokanganisa kuparadzaniswa kweokisijeni kubva kuHb.

9. Simba rekurova. SpO₂ inoyerwa zvichienderana nekushanduka kwekunyura kunoitwa nearterial pulsation, saka mudziyo wekutsiva unofanirwa kuiswa panzvimbo ine ropa rinopuruzira. Chero zvinhu zvinonetesa kuyerera kweropa, sekukurudzira kutonhora, kunzwira tsitsi tsinga kufara, chirwere cheshuga uye varwere vane arteriosclerosis, zvinoderedza kuyerwa kwechiridzwa. SpO₂ haigone kuonekwa muvarwere vane cardiopulmonary bypass uye kusungwa kwemwoyo.

10. Yekupedzisira, mushure mokubvisa zvinhu zvose zviri pamusoro apa, usakanganwa kuti SpO₂ inogona kuderedzwa nekuda kwekusashanda kwechiridzwa.

Iyo oximeter chishandiso chakajairika chekutarisa SpO₂. Inogona kukurumidza kuratidza SpO₂ yemuviri wemurwere, kunzwisisa kushanda kweSpO₂ yemuviri, kuona hypoxemia nekukurumidza sezvinobvira, uye kugadzirisa kuchengetedzwa kwemurwere. MedLinket imba inotakurika Temp-pluse oximeter inogona kunyatso uye nekukurumidza kuyera SpO₂ lily level. Mushure memakore ekuenderera mberi kwekutsvaga, kuyerwa kwayo kwechiyero kwakadzorwa pa2%, iyo inogona kuwana kuyerwa kwakaringana kweSpO₂, tembiricha, uye pulse, iyo inogona kusangana nehunyanzvi zvinodiwa. Kuda kuyerwa.

Zvakanakira zveMedLinket's chigunwe clip Temp-pluse oximeter:

1. An kunze tembiricha sensor inogona kushandiswa kuramba achiyera uye kurekodha tembiricha yemuviri

2. Inogona kubatanidzwa kune imwe kunze kweSpO₂ sensor kuti ienderane nevarwere vakasiyana-siyana uye kuwana chiyero chinoramba chiripo.

3. Rekodha pulse rate uye SpO₂

4. Unogona kuseta SpO₂, pulse rate, yepamusoro uye yakaderera miganho yekushisa kwemuviri, uye nekukurumidza kupfuura muganhu.

5. Chiratidziro chinogona kuchinjwa, iyo waveform interface uye yakakura-character interface patent algorithm inogona kusarudzwa, uye inogona kuyerwa nemazvo pasi pemvura isina kusimba uye jitter. Iine serial port function, iyo yakanakira kubatanidzwa kwehurongwa.

6. OLED kuratidza, zvisinei masikati kana usiku, inogona kuratidza zvakajeka

7. Simba rakaderera uye hupenyu hurefu hwebheteri, mari shoma yekushandisa
