oxygen saturation (SaO2) ndi kuchuluka kwa mphamvu ya oxyhemoglobin (HbO2) yomangidwa ndi okosijeni m'magazi kupita ku mphamvu yonse ya hemoglobin (Hb, hemoglobin) yomwe imatha kumangidwa ndi okosijeni, ndiko kuti, kuchuluka kwa okosijeni m'magazi. magazi.zofunika zokhudza thupi magawo.
Kuchuluka kwa okosijeni wamagazi kumayimira thanzi la thupi la munthu ndipo kumatha kuwonetsa thanzi la kupuma kwamunthu komanso dongosolo lamtima.Zimagwira ntchito yofunika kwambiri popewa komanso kuzindikira matenda a anthu.Chifukwa chake, kuyang'anira kuchuluka kwa oxygen m'magazi ndikofunikira kwambiri.tanthauzo la thupi.
Njira yachipatala yosagwiritsa ntchito kuyeza kuchuluka kwa okosijeni m'magazi ndi kugwiritsa ntchito chojambula chala-cuff mtundu wa photoelectric sensor, ndipo kudzaza kwa okosijeni kwa magazi otsika kumagwiritsidwa ntchito m'malo mwa kudzaza kwa okosijeni kwa minofu yamunthu.Kuwunika kuchuluka kwa okosijeni m'magazi kumatha kunyamula mpweya kupita ku oxyhemoglobin m'mapapo.Ikhoza kuwonetsa mwachindunji ntchito ya kupuma kwa mapapu.Muyezo wa anthu athanzi uyenera kukhala woposa 95%, ndipo ukhoza kukhala wotsika mwa osuta.Nthawi zambiri zimaganiziridwa kuti zosakwana 90% ndi chizindikiro chowopsa.
Ngati mpweya wa okosijeni wa m’magazi wachepa m’thupi la munthu, n’zosavuta kuyambitsa zizindikiro monga kutopa ndi kugona, kusowa mphamvu, ndi kukumbukira kukumbukira.Kusakwanira kwa oxygen m'magazi kwa nthawi yayitali kungayambitsenso kuwonongeka kwa ubongo, mtima ndi ziwalo zina.
Ubongo ndi gawo lovuta kwambiri la dongosolo lamanjenje ku hypoxia.Kuchepa kwa hypoxia mu ubongo kungayambitse zizindikiro monga kutopa m'maganizo, kulephera kukhazikika, ndi kukumbukira kukumbukira.Ngati ubongo ukupitirizabe kusowa okosijeni, zidzatsogolera ku imfa ya maselo a mitsempha, ndipo zimakhala zosavuta kukhudza ntchito ya machitidwe ena, omwe amaika moyo pachiswe.Ngati hypoxia ikukulirakulira, kapena hypoxia pachimake, malingaliro a anthu akuwongolera ndi kugwirizanitsa magalimoto adzatayika pang'onopang'ono, ndipo muzovuta kwambiri, kusokonezeka kwa chidziwitso, chikomokere, ngakhale imfa zidzachitika.
Mofanana ndi ubongo, mtima ndi chiwalo chimene chimadya mpweya wambiri ndipo chimakhala ndi mphamvu zambiri za metabolic.Mtima ukakhala wochepa kwambiri wa hypoxic, kugunda kwamtima kolipirira kumawonjezeka koyamba, kugunda kwa mtima ndi kugunda kwamtima kumawonjezeka, kuzungulira kwa magazi kumabweretsa kusowa kwa okosijeni mu mkhalidwe wa hyperdynamic, ndipo nthawi yomweyo kumapanganso kugawanika kwa magazi, ziwiya zaubongo ndi zamitsempha. .Kukula kosankha kuti magazi aperekedwe mokwanira kungayambitse zizindikiro monga kugunda kwa mtima ndi palpitations.Mtima ukapitirizabe matenda a hypoxia, chifukwa cha kudzikundikira kwa subendocardial lactic acid, kaphatikizidwe ka ATP kumachepa, zomwe zimachititsa kuti myocardial kuvutika maganizo, kuchititsa bradycardia, kukomoka msanga, kuchepa kwa magazi ndi kutulutsa kwa mtima, komanso arrhythmias monga ventricular fibrillation komanso ventricular fibrillation. matenda a fibrillation.asystole.Pamene mtima uli ndi hypoxic kwambiri, izi zidzatsogolera ku hypertrophy ya myocardial ndi hypertrophy ya mtima wamtima, kugwira ntchito kwa mtima kumachepa, ndipo kulephera kwa mtima kudzachitika mosavuta..
Kuonjezera apo, kafukufuku wokhudzana ndi ntchito zachipatala watsimikizira kuti kuyang'anira kuchuluka kwa mpweya wa okosijeni m'magazi kuli ndi kofunika kwambiri kutsogolera chithandizo cha matenda a mtima ndi kuyerekezera zomwe zimachitika.
Kuti mupewe kuwononga zinthu zosiyanasiyana m'thupi chifukwa cha hypoxia, ndikofunikira kuyang'anira kuchuluka kwa okosijeni m'magazi m'moyo watsiku ndi tsiku.Kuchokera pakuwonekera kwa njira yowunikira kuchulukidwa kwa okosijeni wamagazi mpaka pano, pulse oximeter yakhala ikugwiritsidwa ntchito kwambiri pazachipatala chifukwa cha zabwino zake zosawononga, zotetezeka komanso zodalirika, zosavuta kugwiritsa ntchito, zogwira mtima, zopitilira nthawi yake, komanso zotsika mtengo.Zakhala zida zofunikira kwambiri zodziwira matenda m'chipinda chodzidzimutsa, chipinda cha opaleshoni ndi chipinda chachipatala chachipatala.
Mwachitsanzo, m'chipinda chodzidzimutsa, chowunikira cha okosijeni m'magazi chimatha kuyang'anira mosalekeza kuchuluka kwa okosijeni m'magazi a wodwalayo, ndiyeno kudziwa momwe mpweya wa okosijeni umayendera malinga ndi kuchuluka kwa machulukitsidwe a okosijeni wamagazi, kuti atsimikizire kuti mpweya wabwino ndi wokwanira.
M'chipinda chogwiritsira ntchito, chowunikira cha okosijeni cha magazi chimatha kuyeza kuchuluka kwa okosijeni, makamaka kwa odwala omwe akudwala kwambiri komanso ma opaleshoni omwe alibe mpweya wabwino, amatha kupereka mpweya wa okosijeni mwamsanga, kotero kuti madokotala akhoza kutenga njira zopulumutsira nthawi yomweyo.M'chipinda choyang'anira, chowunikira cha okosijeni cha magazi chikhoza kuyika zinthu za alamu zogwirizana ndi momwe zimakhalira.Wodwala akapezeka kuti ali ndi vuto la kupuma, kuchepa kwa mpweya wa okosijeni m'magazi, kuthamanga kwa mtima, kuthamanga kwa mtima, ndi zina zotero.
Kuphatikiza apo, ndikofunikira kwambiri pakuwunika kwa ana akhanda, makamaka pozindikira kuti ali ndi hyperoxia kapena hypoxemia mwa ana akhanda ndi makanda obadwa msanga, ndiyeno sinthani mpweya wa zida zoperekera mpweya munthawi yeniyeni molingana ndi zotsatira zowunikira kuti mupewe vuto. wobadwa kumene.kuwonongeka kwa ubongo, maso, ndi mapapo a ana.Panthawi imodzimodziyo, ma oximeter owonjezereka omwe amavala pakhomo afikanso m'maganizo a anthu, ndipo amagwiritsidwa ntchito kwambiri pozindikira matenda, kufufuza, kudziwongolera ndi zina zotero.
Mwachitsanzo, kuwunika mkhalidwe wa magazi mpweya machulukitsidwe mu nthawi kumvetsa wosuta kupuma dongosolo ndi mtima thanzi, kuti azindikire ngati ali ndi hypoxemia posachedwapa, kuti bwino kupewa kapena kuchepetsa imfa mwangozi chifukwa cha hypoxia.
Kuphatikiza apo, oximeter itha kugwiritsidwanso ntchito powunika matenda omeza, kuyesa matenda obanika kutulo, komanso kuyesa kuyeza mpweya wamagazi.Pomaliza, oximeter yakunyumba ilinso ndi ntchito zodziwongolera zotsatirazi - monga chitsogozo cha chithandizo cha okosijeni, ndipo odwala omwe ali ndi vuto la kupuma kwanthawi yayitali amatha kudziwongolera okha kunyumba.
Kuphatikiza apo, owunikira okosijeni wamagazi amagwiritsidwanso ntchito kwambiri pakufufuza zamankhwala azachipatala ndi magawo ena.Mwachitsanzo, pophunzira za kupuma kwa okosijeni m'tulo, kuyang'anira kuchuluka kwa okosijeni m'magazi kumagwiritsidwa ntchito kuti azindikire ngati wodwala ali ndi matenda obanika kutulo kapena kukwanira kwa oxygen usiku.Low machulukitsidwe ndi zina, komaliza matenda aakulu obstructive tracheal matenda.
Itha kugwiritsidwanso ntchito pofufuza zamasewera azaumoyo wamunthu ndipo imakhala ndi gawo lofunikira pazinthu zina zambiri monga: zankhondo, zakuthambo ndi zina zotero.M'tsogolomu, zowunikira zonyamula mpweya wa okosijeni zidzagwiritsidwa ntchito kwambiri pazaumoyo wapakhomo ndi chisamaliro chaumoyo wa anthu ammudzi, zomwe zidzakhala zofunikira kwambiri pakupewa komanso kuzindikira matenda a anthu.Mu kafukufuku ndi chitukuko njira ya oximeter, Narigmed , kudzipereka mosalekeza kuwongolera kuyeza kulondola kwa oximeter, mosalekeza kukhathamiritsa ofooka perfusion ntchito ndi ntchito odana ndi zolimbitsa thupi, ndi kuyembekezera kubweretsa uthenga wabwino kwa anthu ambiri, Narigmed magazi mpweya teknoloji ali paokha. nzeru katundu ufulu, ndi ofooka perfusion PI = 0,025 % Iwo akhoza kukhalabe olondola magazi mpweya ndi kugunda mlingo muyeso pansi kopitilira muyeso-otsika ofooka perfusion ndi zina pafupipafupi zoyenda zokhazikika ndi zoyenda mwachisawawa, amene mosakayikira mtsogoleri pakati Chinese zachipatala. makampani opanga zida.
