Mfundo ntchito ndi ntchito spo2 sensa

Mfundo yogwira ntchito ya spo2 sensa

ZachikhalidweChithunzi cha SpO2Njira yoyezera ndiyo kusonkhanitsa magazi kuchokera m'thupi, ndikugwiritsa ntchito chowunikira mpweya wamagazi poyesa electrochemical kuyeza kuthamanga pang'ono kwa okosijeni wamagazi PO2 kuwerengera kuchuluka kwa okosijeni m'magazi.Komabe, ndizovuta kwambiri ndipo sizingayang'anitsidwe mosalekeza.Chifukwa chake, oximeter idayamba kukhalapo.

Oximeter imapangidwa makamaka ndi microprocessor, kukumbukira (EPROM ndi RAM), otembenuza awiri a digito-to-analogi omwe amawongolera ma LED pa chipangizo .zosefera ndikukulitsa chizindikiro cholandilidwa ndi photodiode, ndikuyika chizindikiro cholandirira kuti apereke analogi ya microprocessor. - digito converter wapangidwa.

The oximeter imatenga chithunzi chala chala chala.Muyenera kuika kachipangizo pa chala pamene kuyeza.kugwiritsa ntchito chala monga mandala chidebe hemoglobin, ndi ntchito kuwala kofiira ndi wavelength 660 nm ndi pafupi-infuraredi kuwala ndi wavelength 940 nm monga cheza.Lowetsani gwero la kuwala ndikuyesa kukula kwa kufalikira kwa kuwala kudzera pa bedi la minofu kuti muwerenge kuchuluka kwa hemoglobini ndi kuchuluka kwa okosijeni wamagazi.

Anthu ovomerezeka aoximeter

1. Anthu omwe ali ndi matenda a mitsempha (matenda a mtima, matenda oopsa, hyperlipidemia, cerebral thrombosis, etc.)

Pali lipid madipoziti mu mtima lumen, ndipo magazi si yosalala, zomwe zidzachititsa kuti kuvutika kwa mpweya.The oximeter mosavuta kufufuza magazi mpweya wa thupi la munthu.

2.Odwala mtima

Magazi a viscous, pamodzi ndi kuuma kwa mitsempha ya m'mitsempha, amachepetsa lumen ya mitsempha, zomwe zimapangitsa kuti magazi asamayende bwino komanso kuti mpweya ukhale wovuta.Thupi ndi "hypoxia" tsiku lililonse.Hypoxia yofatsa ya nthawi yayitali, mtima, ubongo ndi ziwalo zina zokhala ndi mpweya wambiri zimachepa pang'onopang'ono.Chifukwa chake, kugwiritsa ntchito kwanthawi yayitali kwa pulse oximeter kuyeza kuchuluka kwa okosijeni m'magazi a odwala amtima ndi cerebrovascular kumatha kupewetsa ngozi.Ngati hypoxia ichitika, chigamulo chowonjezera mpweya chimapangidwa nthawi yomweyo, chomwe chingathe kuchepetsa mwayi wa matenda.

3. Anthu omwe ali ndi matenda opuma (asthma, bronchitis, bronchitis, matenda a mtima, etc.)

Kuyeza mpweya wa magazi kwa odwala omwe akupuma ndikofunika kwambiri.Kumbali imodzi, kupuma movutikira kungayambitse kuperewera kwa oxygen.Kumbali inayi, kulimbikira kwa mphumu kumathanso kutsekereza ziwalo zazing'ono, kupangitsa kusinthana kwa gasi kukhala kovuta ndikupangitsa hypoxia.Zimayambitsa kuonongeka kosiyanasiyana kwa mtima, mapapo, ubongo ngakhalenso impso.Chifukwa chake, kugwiritsa ntchito pulse oximeter kuti muwone zomwe zili m'magazi a oxygen kungachepetse kuchuluka kwa kupuma.

4. Akuluakulu azaka zopitilira 60

Thupi la munthu limadalira magazi kuti litumize mpweya.Ngati magazi ali ochepa, mwachibadwa padzakhala mpweya wochepa.Ndi mpweya wochepa, thupi limachepa mwachibadwa.Choncho, okalamba ayenera kugwiritsa ntchito pulse oximetry kuyesa magazi tsiku lililonse.Pamene mpweya wa magazi uli pansi pa mlingo wochenjeza, mpweya uyenera kuwonjezeredwa mwamsanga.

5.Masewera ndi masewera olimbitsa thupi

Kuchita masewera olimbitsa thupi kwa nthawi yayitali komanso kuchita masewera olimbitsa thupi molimbika kumakonda kukhala ndi hypoxia, yomwe imakhudza thanzi la myocardial ndi ubongo.Monga okonda masewera;ogwira ntchito zamaganizo;okonda kuyenda kumapiri.

6.Anthu omwe amagwira ntchito maola oposa 12 tsiku limodzi

Kugwiritsidwa ntchito kwa okosijeni muubongo kumapangitsa 20% ya thupi lonse kutenga okosijeni, ndipo kumwa kwa okosijeni muubongo kumawonjezeka mosapeŵeka ndi kusintha kwa ntchito zamaganizidwe.Thupi la munthu limatha kutulutsa mpweya wochepa, limadya kwambiri, komanso limadya pang'ono.Kuphatikiza pa kuyambitsa chizungulire, kutopa, kukumbukira kukumbukira, kuyankha pang'onopang'ono ndi mavuto ena, kungayambitsenso kuwonongeka kwakukulu ku ubongo ndi myocardium, ngakhale imfa chifukwa chogwira ntchito kwambiri.Chifukwa chake, anthu omwe amaphunzira kapena kugwira ntchito maola 12 patsiku ayenera kugwiritsa ntchito pulse oximetry kuyesa mpweya wamagazi tsiku lililonse Zokhutira, kuyang'anira thanzi la okosijeni wamagazi nthawi ndi nthawi, kuti atsimikizire thanzi la mtima ndi ubongo.
