Kumenyekanisha ibyuma bya ogisijeni yubuvuzi, kuki RGM ikenera sensor ya ogisijeni?

Ibyuma bya Oxygene bikoreshwa mu gupima no kugenzura urugero rwa ogisijeni, umwuka wa ogisijeni uhumeka kandi ugasohoka n'umurwayi uhujwe na mashini ihumeka cyangwa anesthesia.
Umuyoboro wa ogisijeni uri mu cyuma gihumeka (RGM) upima ingufu za ogisijeni (cyangwa) umwuka wa ogisijeni igice cyavanze na gaze ihumeka.
Ibyuma bya Oxygene bizwi kandi nka sensor ya FiO2 cyangwa bateri ya O2, naho agace ka ogisijeni ihumeka (FiO2) ni uguteranya ogisijeni mu ruvange rwa gaze.Igice cya ogisijeni cyahumetswe kivanze na gaze mu kirere cyo mu kirere ni 21%, bivuze ko umwuka wa ogisijeni mu kirere cyo mu cyumba ari 21%.
Kuki RGM ikenera sensor ya ogisijeni?
Gukurikirana gazi zose zihumeka zagenewe kwimura uruvange rwumwuka na ogisijeni mu bihaha by’umurwayi no gusohoka mu bihaha by’umurwayi kugira ngo bifashe guhumeka, cyangwa rimwe na rimwe, kugira ngo bihumeke neza ku murwayi udahumeka udahagije cyangwa umubiri we udashobora guhumeka.
Mugihe cyo guhumeka, harasabwa gupima neza imvange ya gaze ihumeka.By'umwihariko, gupima ogisijeni mugihe cyo guhumeka ni ngombwa kubera akamaro kayo muri metabolism.Muri iki gihe, sensor ya ogisijeni ikoreshwa mu kugenzura no kumenya itangwa rya ogisijeni yabazwe.Igisabwa nyamukuru ni ugutanga ibipimo nyabyo byerekana umwuka wa ogisijeni mu myuka ihumeka.Uburyo butandukanye bwo kuvura Oxygene yubuvuzi
Amashanyarazi
Fluorescent sensor sensor
1. Amashanyarazi ya ogisijeni
Ibikoresho bya elegitoroniki ya ogisijeni ikoreshwa cyane mu gupima umwuka wa ogisijeni mu kirere kidukikije.Ibyo byuma byinjizwa mumashini ya RGM kugirango bipime ubunini bwa ogisijeni.Basiga imiti ihindagurika mubintu byunvikana, bikavamo amashanyarazi akwiranye nurwego rwa ogisijeni.Imashini zikoresha amashanyarazi zihindura ingufu za chimique ingufu zamashanyarazi binyuze muri okiside no kugabanya inzira.Itanga amashanyarazi kubikoresho bikwiranye nijanisha rya ogisijeni muri cathode na anode.Umuyoboro wa ogisijeni ukora nk'isoko y'ubu, bityo gupima voltage bikozwe binyuze mu kurwanya imitwaro.Ibisohoka byumuvuduko wa ogisijeni ugereranije nigipimo cyo gukoresha ogisijeni na sensor ya ogisijeni.
2. Fluorescent sensor ya sensor
Ibyuma bya ogisijeni optique bishingiye ku ihame rya kuzimya fluorescence.Bishingikiriza kumikoreshereze yumucyo, ibyuma byerekana urumuri nibikoresho bya luminescent bifata urumuri.Luminescence ishingiye kuri ogisijeni isimbuza amashanyarazi ya ogisijeni ya elegitoroniki mu bice byinshi.
Ihame rya molekile ya ogisijeni fluorescence yazimye kuva kera.Molekile zimwe cyangwa ibice bya fluoresce (ni ukuvuga kohereza ingufu z'umucyo) iyo bihuye numucyo.Ariko, niba molekile ya ogisijeni ihari, ingufu z'umucyo zoherezwa kuri molekile ya ogisijeni, bigatuma fluorescence nkeya.Ukoresheje isoko yumucyo uzwi, ingufu zumucyo zagaragaye ziragereranywa numubare wa molekile ya ogisijeni murugero.Kubwibyo, fluorescence nkeya igaragara, molekile nyinshi ya ogisijeni igomba kuba ihari muri gaze ntangarugero.
