Kodi sensa ya okosijeni wamagazi imachita chiyani?

Anthu amapuma mpweya tsiku lililonse, chifukwa mpweya uli ndi mpweya, womwe ndi maziko osungira miyoyo ya anthu.Hemoglobin yochepetsedwa yomwe ili m’matupi a anthu imaphatikizana ndi mpweya wolowetsedwa m’mapapo kupanga mpweya ndi hemoglobini.Oxygen amasungunuka mu plasma kuti asunge kagayidwe kake ka maselo a minofu.Sensa ya okosijeni imatha kuyeza kuchuluka kwa hemoglobin m'magazi amunthu m'magazi onse.Zotsatirazi zikufotokozera ntchito ya sensa ya okosijeni wamagazi:

Sensa ya okosijeni ya magazi imatha kuyeza kuchuluka kwa okosijeni m'magazi m'thupi la anthu.Kuchuluka kwa okosijeni m'mwazi kumatanthauza kuchuluka kwa hemoglobini wokhala ndi okosijeni m'mwazi wamagazi a anthu m'mwazi.Kuchuluka kwa okosijeni m'magazi ndi chizindikiro chofunikira choyezera wodwalayo.Sensa ya okosijeni ya magazi imagawidwa m'mawonekedwe osiyanasiyana, monga chala chala, mtundu wa earlobe ndi mtundu womatira pamphumi.Mosasamala kanthu za mawonekedwe, pachimake cha sensa ya okosijeni ya magazi idakali yofanana, yomwe imapangidwa ndi zipangizo zopangira kuwala ndi kulandira zipangizo.Chida chotulutsa kuwala cha sensa ya okosijeni wamagazi chimapangidwa ndi chubu chowala cha infrared, ndipo cholandila chithunzi cha sensa ya okosijeni yamagazi imatenga PIN photosensitive diode, yomwe imasintha chizindikiro chowala chomwe chalandilidwa kukhala chizindikiro chamagetsi, ndikutengera ukadaulo wapamwamba kwambiri. sinthani.Akagwiritsidwa ntchito, malo olandirira amakhala aakulu, kukhudzidwa kumakhala kwakukulu, mdima wakuda ndi wochepa, ndipo phokoso limakhala lochepa.Kayendetsedwe ka sensa ya okosijeni ya m'magazi imagwiritsa ntchito ma diode awiri otulutsa mpweya ndi chubu cholandirira chojambula kuti azindikire njira yoyezera milingo iwiri yoyezera kuchuluka kwa okosijeni m'magazi.Kugwiritsiridwa ntchito kwa njira yoyendetsa galimotoyi sikungangowonjezera nthawi yomweyo Kuwonjezera pa kuchepetsa kugwiritsa ntchito mphamvu, kungathenso kutalikitsa moyo wautumiki wa nthawiyo.Sensa ya okosijeni ya magazi imatenganso njira yoyezera magazi, yomwe ndi njira yopitilira komanso yosawononga mpweya wa okosijeni wamagazi, womwe sudzabweretsa ululu ndi zotsatirapo za thupi la munthu.
