Gusobanukirwa Ikizamini cya Sensor

Bya Andereya Clay, Fluke Biomedical

Icyitonderwa cya Muhinduzi: Iyi ngingo, yanditswe muri 2015, ikomeje kuba iyasomwe cyane24 × 7'Urubuga.Turizera ko ishobora kuguha amakuru ukeneye mugihe ugerageza SpO₂Rukuruzi.

Gukurikirana SpO₂, ijanisha ryuzuye rya ogisijeni mumaraso, ryabaye urwego rwo kwita kubarwayi kwisi yose.Hafi ya buri murwayi wumurwayi afite ubushobozi bwubatswe cyangwa bufatika bwo gukurikirana iki kimenyetso cyingenzi.SPO₂ni uburyo butaziguye kandi budasobanutse bwo gupima umwuka wa ogisijeni mu maraso.Igomba gupimwa hamwe nibindi bipimo byose bya physiologique mugihe cyo gukumira cyangwa gukosora kuri monitor yumurwayi, cyangwa igikoresho cyonyine.

Ikoranabuhanga

SpO₂bipimirwa kuri peripheri, ubusanzwe urutoki, kandi ni igipimo kimwe cyubuzima bwimitsi yumutima nimiyoboro yubuhumekero.Impanuka ya oximeter idapima gupima umwuka wa ogisijeni wamaraso yumurwayi.Iki gikoresho kigizwe numucyo utukura hamwe na infragre yumucyo, ibyuma bifata amafoto, hamwe nubushakashatsi bwo kohereza urumuri binyuze muburiri bworoshye, butera arterial, mubusanzwe urutoki cyangwa gutwi.Oxygene ya hemoglobine (O.₂Hb) na deogisijene ya hemoglobine (HHb) ikurura urumuri rutukura na infragre mu buryo butandukanye.Ijanisha ryuzuye rya hemoglobine mumaraso ya arterial irashobora kubarwa mugupima impinduka zinjira mumucyo ziterwa no gutembera kwamaraso.

Impamvu zitandukanye zirashobora kugira ingaruka kuri SPO₂gupima, harimo imiterere yuruhu, pigment, ibikomere, tissue yinkovu, tatouage, imisumari yimisumari, hypothermia, anemia, imiti, kwivanga kwumucyo, no kugenda.

SPO₂bipimwa hifashishijwe sensor, mubisanzwe bifatanye nurutoki rwumurwayi.Hariho uburyo bubiri bwa SpO₂ikoranabuhanga: kwanduza no kwerekana.Uburyo bwo kwanduza nuburyo bukunze gukoreshwa byombi.Nkuko bigaragara ku gishushanyo cya 1, tekinoroji yanduza yohereza urumuri rutukura na infragre binyuze mu rutoki rugana ifoto.

Igishushanyo 1: Ikoranabuhanga ryanduza, uburyo bukoreshwa cyane bwa clinique pulse oximetry.Kanda kugirango ubunini.Ubundi buryo bukoreshwa kuri SPO₂yishingikiriza ku buhanga bugaragaza.Nkuko bigaragara ku gishushanyo cya 2, ubu buryo bufite transmitter hamwe niyakira mu ndege imwe.SPO Yerekana₂sensor irashobora gushirwa mubindi bice bya anatomy kuruta urutoki, nkuruhanga.

Igishushanyo 2: Ikoranabuhanga ryerekana, ubundi buryo bwo gupima kwanduza.Kanda kugirango ubunini

Kwipimisha

Buri ruganda rwa pulse oximetry rugomba kumenya neza igikoresho cyabo mugupima abantu.Nkuko Dennis J. McMahon abisobanura mu mpapuro ze zera, "Nta kintu nk'iki nka SpO₂Wigana. ”¹mu “bushakashatsi bwakozwe na desaturation bugenzurwa, abakorerabushake bahumeka uruhererekane rw'imvange ya gaze yo kugabanya umwuka wa ogisijeni mu gihe uhujwe na monitor ya prototype.”Amaraso ya Arterial noneho akurwa mubintu kugirango bapime umwuka wa ogisijeni muri laboratoire.

Ibisubizo by'iki kizamini ni igishushanyo kuri ubwo buryo bwihariye bwa SPO₂sensor na monitor.Iyi shusho ivugwa nka R-umurongo.Nkuko bigaragara ku gishushanyo cya 3, R-umurongo isobanura isano iri hagati yikigereranyo cyihariye cyumucyo utukura na infragre hamwe nubwuzure bwa ogisijeni yagaragaye nkuko byakusanyirijwe mugihe cyo kwipimisha abantu.R-umurongo noneho ikoreshwa mubikoresho bya software kubikoresho runaka no kuri SPO₂ibizamini.

Igishushanyo 3: Urugero rwa R-umurongo, uhuza O2 kuzura hamwe nagaciro ka R.Kanda kugirango wongereSimulator, kalibatori, hamwe nabapimisha imikorere ya pulse oximeter isobanurwa muri ISO isanzwe 80601-2-61.Bitandukanye nubundi bwoko bwibikoresho byubuvuzi, pulse oximeter ntabwo yagenewe guhindurwa hanze yuruganda.Nta buryo bwemewe bwo kugenzura kalibrasi yukuri ya pulse oximeter usibye kwipimisha abantu.SpO₂ibikoresho byo kwipimisha kumasoko biri murwego rwibizamini.

Ku bwa Tobey Clarke mu gitabo cyeIbikoresho byubuvuzi Ubwishingizi bufite ireme, abagenzuzi b'abarwayi bagomba gupimwa imikorere byibuze buri mwaka.²Abagerageza benshi bakora bipimisha SPO₂Rukuruzi.Ibi biremera ikizamini cya sensor, umugozi, na monitor.Abagerageza bamwe bakora binjiza ikimenyetso kuri moniteur, gusa bagerageza monitor.Abandi barashobora kugerageza umugozi kugirango bakomeze.Ibizamini byinshi bikora gusa bipima tekinoroji yohereza, ntabwo byerekana.

Ibikorwa bisanzwe byo gupima monitor yumurwayi cyangwa kwihagararaho wenyine SPO₂monitor ikubiyemo kugenzura imiterere yumubiri, gukora ibizamini byumutekano wamashanyarazi, gukora ikintu icyo aricyo cyose cyakozwe nabashinzwe gukora cyo gukumira, gukora ibizamini (harimo gutabaza nibindi bizamini byihariye), hanyuma, hanyuma, byerekana ibisubizo byikizamini.

Andereya Clay ni umuyobozi ushinzwe kwamamaza ibicuruzwa bya Fluke Biomedical, Everett, Gukaraba.Iyi ngingo yakuwe mu gitabo cyitwa Fluke Biomedical whitepaper.
