Nigute ushobora gukoresha neza impiswi yo gupima ogisijeni?

Impanuka ya oxydeByakoreshejwe mu gusuzuma imiterere ya ogisijeni y’abarwayi mu mavuriro atandukanye byahindutse ibikoresho bisanzwe byo gukurikirana.Itanga ubudahwema, butagenzura kugenzura ogisijeni ya hemoglobine mu maraso ya arterial.Buri pulse wave izavugurura ibisubizo byayo.

Imisemburo ya pulse ntabwo itanga amakuru kubyerekeranye na hémoglobine, umusaruro wumutima, imikorere ya ogisijeni mu ngingo, gukoresha ogisijeni, okisijeni, cyangwa guhumeka neza.Ariko, batanga amahirwe yo guhita bamenya gutandukana kwa ogisijeni yumurwayi, nkikimenyetso cyo kuburira hakiri kare abaganga kugirango bafashe gukumira ingaruka ziterwa no guta umutwe no kumenya hypoxemia mbere yuko habaho osis.

Hasabwe ko kongera imikoreshereze yaimpiswimuri rusange ibyumba birashobora kubikora nkibipimo bya termometero.Icyakora, biravugwa ko abakozi bafite ubumenyi buke ku mikorere yibi bikoresho, 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 ya hemoglobine.Amaraso ya ogisijeni ya Arterial aratukura kubera ubwinshi bwa ogisijeni ya hemoglobine irimo, ituma yakira urumuri runaka rw'urumuri.Ubushakashatsi bwa oximeter bufite diode ebyiri zisohora urumuri (LED) kuruhande rumwe rwa probe, umutuku umwe na infragre.Iperereza rishyirwa mubice bikwiye byumubiri, mubisanzwe urutoki cyangwa urutoki, kandi LED yohereza urumuri rwumucyo kuri Photodetector kurundi ruhande rwiperereza binyuze mumaraso atembera.Oxyhemoglobin ikurura urumuri rwa infragre;kugabanya hemoglobine bivamo urumuri rutukura.Amaraso ya pulsatile arterial muri systole atera ogisijeni hemoglobine itembera mumubiri, ikurura urumuri rwinshi, kandi bigatuma urumuri ruto rugera kuri fotodektor.Umwuka wa ogisijeni wamaraso ugena urugero rwo kwinjiza urumuri.Ibisubizo bitunganyirizwa muburyo bwa digitale yuzuye ya ogisijeni kuri ecran ya oximeter, ihagarariwe na SpO2.

Hano hari ababikora benshi nicyitegererezo cya pulse oximeter.Benshi batanga amashusho yububiko bwa digitale, amajwi yumvikana ya arterial no kwerekana umutima, hamwe na sensor zitandukanye zijyanye nabantu bafite imyaka, ubunini cyangwa uburemere.Guhitamo biterwa nigenamiterere rikoresha.Abakozi bose bakoresha pulse oximeter bagomba kumva imikorere yayo no gukoresha neza.

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

Imiterere yumurwayi-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 idakomeye cyangwa idahari ,.impiswigusoma bizaba bidahwitse.Abarwayi bafite ibyago byinshi byo kurwara hypoperfusion ni abafite hypotension, hypovolemia, na hypothermia, nabafite umutima.Abantu bafite ubukonje ariko butari hypothermia barashobora kugira vasoconstriction mu ntoki no mumano kandi birashobora kubangamira umuvuduko wamaraso.

Niba iperereza ryakosowe cyane, hashobora kuboneka impiswi itari arterial, igatera urutoki.Imitsi itera kandi iterwa no kunanirwa k'umutima kuruhande, kugarura tricuspid, hamwe na tourniquet yumuvuduko wamaraso hejuru yubushakashatsi.

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

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 rwazamutse.

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