Umgaqo womlinganiselo
I-SpO2 yokulinganisa i-plethysmogram isetyenziselwa ukumisela ukugcwala kwe-oksijini ye-hemoglobin
igazi lomthambo.I-parameter ye-SpO2 inokubonelela ngomqondiso wezinga le-pulse kunye namandla e-pulse.Njani iSpO2
iparameter iyasebenza
I-SpO2 ngumlinganiselo ongekho-invasive we-saturation ye-oxygen esebenzayo.
I-Arterial oxygen saturation ilinganiswa ngendlela ebizwai-pulse oximetery.Yinto eqhubekayo, engahlaseliyo
Indlela esekwe kwiintlobo ezahlukeneyo zokufunxwa kwe-hemoglobin kunye ne-oxyhemoglobin (ebizwa ngokuba
umgaqo we-spectrophotometer).Ilinganisa ukuba kungakanani ukukhanya, okuthunyelwa kwimithombo yokukhanya kwelinye icala le-sensor,
isasazwa ngezicubu zesigulana (ezifana nomnwe okanye uzwane), ukuya kumamkeli kwelinye icala.
Umlinganiselo womlinganiselo we-sensor wavelengths kuthiwa yi-660nm ye-LED ebomvu kunye ne-940nm ye-infrared LED.
Ubuninzi bemveliso yamandla okukhanya kwi-LED yi-4mw.
Ubungakanani bokukhanya obugqithisiweyo buxhomekeke kwizinto ezininzi, ezininzi zazo zihlala zihlala njalo.Nangona kunjalo, enye ye
ezi zinto, ukuhamba kwegazi kwi-arteries, iyahluka ngokuhamba kwexesha, kuba i-pulsating.Ngokulinganisa ukukhanya
Ukufunxa ngexesha lokubetha, kunokwenzeka ukuba ufumane i-oxygen saturation ye-arterial blood.Ukufumanisa i
I-pulsation inika i-PLETH waveform, isignali yezinga le-pulse kunye namandla e-pulse.
Ixabiso le-SpO2, ixabiso le-PR, amandla e-pulse kunye ne-PLETH waveform inokuboniswa kwisikrini esikhulu.
Amanyathelo omlinganiselo
Ukukhetha inzwa yeUmlinganiselo we-SpO2kuxhomekeke kwiminyaka yesigulana.Kwisigulane esidala, unokukhetha
inzwa yomnwe omdala;kwisigulane somntwana, unokukhetha isandla somntwana okanye inzwa yenzwane.Umnwe SpO2
Uluvo sisisihlunu somnwe esinamalungu amabini.Ii-LED zibekwe kwindawo enye kunye ne-photodetector
ibekwe kwenye indawo.
Nceda ulandele la manyathelo kunye nomfanekiso 6- 1 ngezantsi ukusebenzisa isivamvo somnwe omdala we-SpO2:
Faka isidibanisi senzwa kwisokethi ye-Oximeter's SpO2.
Layita umboniso.Isikrini se-LCD siya kubonisa isikrini sokujonga ipharamitha.Ncamathisela isixhobo soluvo kwi
indawo efanelekileyo yomnwe wesigulane.Izifundo ziya kuboniswa kwisikrini se-LED umzuzwana kamva.
Qinisekisa ukuba ubeke inzwa ye-SpO2 oh umnwe kwicala elichanekileyo.Inxalenye ye-LED yenzwa kufuneka
ube ngasemva kwesandla sesigulane kunye nenxalenye ye-photodetector ngaphakathi.Qinisekisa ukufaka umnwe
kubunzulu obufanelekileyo kwisixhobo soluvo ukuze uzipho luchasane nokukhanya okukhutshiweyo kwisixhobo soluvo.
Ukufumana iziphumo ezichanekileyo, nceda ufunde idatha de isivamvo sibekwe ngokuthe chu.Ukufundwa kusenokungabikho
ichanekile xa mhlawumbi isivamvo okanye isigulana sihamba
