Nigute ushobora gukoresha neza impiswi yo gupima ogisijeni?

Impanuka ya oximeterikoreshwa mugusuzuma umwuka wa ogisijeni wabarwayi mumavuriro atandukanye yabaye ibikoresho bisanzwe byo gukurikirana.Itanga igenzura rihoraho, ridahwitse ryuzuye rya ogisijeni ya hemoglobine mu maraso ya arterial.Buri pulse wave izavugurura ibisubizo byayo.

Oxymeter ya pulse ntabwo itanga amakuru ajyanye no kwibanda kwa hemoglobine, gusohora umutima, gukora neza kwa ogisijeni mu ngingo, gukoresha ogisijeni, okisijeni, cyangwa guhumeka neza.Icyakora, batanga amahirwe yo guhita bamenya gutandukana nu mwuka wa ogisijeni wumurwayi, nkikimenyetso cyo kuburira hakiri kare abaganga kugirango bafashe gukumira ingaruka ziterwa no guta umutwe no kumenya hypoxemia mbere yuko habaho osis.

Hasabwe ko kongera ikoreshwa ryaimpiswimuri rusange ibyumba birashobora kubikora nkibipimo bya termometero.Icyakora, biravugwa ko abakozi bafite ubumenyi buke ku mikorere y’ibikoresho, kandi ubumenyi buke ku ihame ryimikorere ryibikoresho nibintu bishobora kugira ingaruka kubisomwa.

Ugereranije na gemoglobine yagabanutse, oximeter ya pulse irashobora gupima iyinjizwa ryumurambararo wihariye wumucyo muri okiside hemoglobine.Amaraso ya ogisijeni ya Arterial aratukura kubera ubwinshi bwa ogisijeni ya hemoglobine irimo, ituma ikurura uburebure bwumucyo.Oximeter probe ifite diode ebyiri zisohora urumuri (LED) kuruhande rumwe rwa probe, imwe itukura nimwe ya infragre.Iperereza rishyirwa ku gice kibereye cyumubiri, ubusanzwe urutoki cyangwa urutoki, kandi LED yohereza uburebure bwumucyo kuri fotodetector kurundi ruhande rwiperereza binyuze mumaraso arterial.Oxyhemoglobin ikurura urumuri rwa infragre;kugabanya hemoglobine bivamo itara ritukura.Amaraso ya pulsatile arterial muri systole atera ogisijeni ya hemoglobine itembera mumubiri, ikurura urumuri rwinshi rwa infragre, kandi bigatuma urumuri ruto rugera kuri Photodetector.Umwuka wa ogisijeni w'amaraso ugena urugero rwo kwinjiza urumuri.Ibisubizo bitunganyirizwa muburyo bwa digitale yuzuye ya ogisijeni kuri ecran ya oximeter, ihagarariwe na SpO2.

Hariho ababikora benshi nicyitegererezo cya pulse oximeter.Benshi batanga amashusho ya digitale yerekana amashusho, yumvikana arterial beat hamwe numutima utera, hamwe na sensor zitandukanye zijyanye nabantu bafite imyaka, ingano cyangwa uburemere.Guhitamo biterwa nigenamiterere rikoresha.Abakozi bose bakoresha pulse oximeter bagomba kumva imikorere yayo no gukoresha neza.

Isesengura ryamaraso ya arterial nukuri;icyakora, pulse oximetry ifatwa nkukuri bihagije kubikorwa byinshi byubuvuzi kubera imbogamizi zamenyekanye.

Imiterere y'abarwayi-Kubara itandukaniro riri hagati ya capillaries na capillaries yubusa, oximetry ipima kwinjiza urumuri rwinshi (mubisanzwe bitanu).Kugirango umenye amaraso atembera, hagomba gukorerwa parufe ihagije mugace gakurikiranwa.Niba impiswi yumurwayi ya periferique ifite intege nke cyangwa idahari ,.impiswigusoma bizaba bidahwitse.Abarwayi bafite ibyago byinshi byo kurwara hypoperfusion ni abafite hypotension, hypovolemia, na hypothermia, hamwe nabafashwe numutima.Abantu bafite ubukonje ariko butari hypothermie barashobora kugira vasoconstriction mu ntoki no mu mano kandi bishobora kubangamira umuvuduko wamaraso.

Niba iperereza ryarakosowe cyane, impiswi zidasanzwe zidasanzwe zirashobora kuboneka, bigatera imitsi y'urutoki.Imitsi itera kandi iterwa no kunanirwa k'umutima kuruhande, kugarura tricuspid, hamwe na tourneque yumuvuduko wamaraso hejuru yubushakashatsi.

Arththmia yumutima irashobora gutera ibisubizo byo gupima bidakwiye cyane cyane mugihe hari defisit ya apex / igufwa rikomeye.

Irangi ryimitsi ikoreshwa mugupima no gupima hemodinamike irashobora gutera igereranya ridahwitse ryuzuye rya ogisijeni, mubisanzwe ni bike.Ingaruka ziterwa na pigmentation yuruhu, jaundice, cyangwa urwego rwa bilirubin rwiyongereye.

Gukoresha neza ibipimo bya pulse oximetry ntabwo bikubiyemo gusoma gusa ibyerekanwe na digitale, ariko kandi nibindi byinshi, kuko ntabwo abarwayi bose bafite SpO2 imwe badafite ogisijeni imwe mumaraso.Kwuzura kwa 97% bivuze ko 97% ya hemoglobine yose mumubiri yuzuyemo molekile ya ogisijeni.Kubwibyo, kwiyuzuza ogisijeni bigomba gusobanurwa murwego rwumurwayi wa hemoglobine.Ikindi kintu kigira ingaruka kumasomo ya oximeter nukuntu hemoglobine ihuza cyane na ogisijeni, ishobora gutandukana nimpinduka mubihe bitandukanye bya physiologique.
