Ukuqapha kwe-SpO2!

Umgomo wokulinganisa

I-SpO2 plethysmogram measurement isetshenziswa ukunquma ukugcwala komoyampilo kwe-hemoglobin

igazi le-arterial.Ipharamitha ye-SpO2 nayo inganikeza isignali yesilinganiso sokushaya kwenhliziyo namandla okushaya kwenhliziyo.Ungayenza kanjani i-SpO2

 ipharamitha iyasebenza

I-SpO2 isilinganiso esingahlanyisi sokugcwala komoyampilo okusebenzayo.

I-Arterial oxygen saturation ikalwa ngendlela ebizwa ngokuthii-pulse oximetery.Kuyinto eqhubekayo, engahlaseli

Indlela esekelwe ekumunceni okuhlukile kwe-spectra kwe-hemoglobin ne-oxyhemoglobin (ebizwa

Isimiso se-spectrophotometer).Ikala ukuthi kungakanani ukukhanya, okuthunyelwa emithonjeni yokukhanya ohlangothini olulodwa lwenzwa,

idluliselwa ngezicubu zesiguli (njengomunwe noma uzwane), kumamukeli ngakolunye uhlangothi.

Amaza okulinganisa inzwa abizwa ngokuthi ama-660nm e-LED ebomvu kanye ne-940nm ye-infrared LED.

Ubukhulu bokukhipha amandla okukhanya kwe-LED ngu-4mw.

Inani lokukhanya elidluliswayo lincike ezintweni eziningi, eziningi zazo ezingashintshi.Nokho, omunye

lezi zici, ukugeleza kwegazi emithanjeni, kuyahlukahluka ngokuhamba kwesikhathi, ngoba i-pulsating.Ngokulinganisa ukukhanya

ukumuncwa ngesikhathi sokushaya kwenhliziyo, kungenzeka ukuthola ukugcwala komoya-mpilo egazini le-arterial.Ukuthola i-

i-pulsation inikeza i-PLETH waveform, isignali yezinga lokushaya kwenhliziyo namandla okushaya kwenhliziyo.

Inani le-SpO2, inani le-PR, amandla okushaya kwenhliziyo kanye ne-PLETH waveform kungaboniswa esikrinini esikhulu .

Izinyathelo Zokukala

Ukukhetha inzwa kweIsilinganiso se-SpO2kuncike eminyakeni yesiguli.Ngesiguli esikhulile, ungakhetha

inzwa yomunwe omdala;esigulini sengane, ungakhetha isandla somntwana noma inzwa yezinzwane.Umunwe SpO2

inzwa isiqeshana somunwe esinezingxenye ezimbili.Ama-LED abekwe engxenyeni eyodwa kanye ne-photodetector

ibekwe kwenye ingxenye.

Sicela ulandele izinyathelo kanye nomfanekiso 6- 1 ngezansi ukuze usebenzise inzwa yomunwe omdala ye-SpO2:

Faka isixhumi senzwa kusokhethi ye-Oximeter's SpO2.

Vula ukunyakaza.Isikrini se-LCD sizobonisa isikrini sokuqapha ipharamitha.Namathisela inzwa ku-an

indawo efanele yomunwe wesiguli.Ukufundwa kuzovezwa esikrinini se-LED ngemva kwesikhashana.

Qiniseka ukuthi ubeka inzwa ye-SpO2 oh umunwe endaweni efanele.Ingxenye ye-LED yenzwa kufanele

ibe ngemuva kwesandla sesiguli kanye nengxenye ye-photodetector ngaphakathi.Qiniseka ukuthi ufaka umunwe

ekujuleni okufanele kwinzwa ukuze uzipho luhluke nje ekukhanyeni okuphuma kunzwa.

Ukuze uthole imiphumela enembile, sicela ufunde idatha kuze kube yilapho inzwa ibekwe kancane.Ukufundwa kungase kungabi

olunembile lapho inzwa noma isiguli sihamba
