Kukhazikika kwa miyeso ndi chizindikiro chofunikira kwambiri pakuwunika momwe wodwalayo alili.Poyezera kuchuluka kwa okosijeni m'magazi, wowunikirayo amagwiritsa ntchito njira yapawiri-wavelength pulsatile photoplethysmography.Posanthula mayamwidwe osiyanitsidwa a kuwala kofiira ndi infrared ndi hemoglobin ya oxygen (HbO2) ndi hemoglobin (Hb) m'magazi, kuchuluka kwa machulukitsidwe a okosijeni m'magazi anthawi yeniyeni amawerengedwa.Kuti muwonetsetse zotsatira zokhazikika, chowunikira chimagwiritsa ntchito zofunika kwambiri pakutulutsa kwa LED ndi kulandila kwa photodetector kuti zisasokonezedwe.The HM-10 oximetry probe imagwiritsa ntchito mawonekedwe olumikizana ndi ma pini khumi, kupangitsa chitetezo chosiyana potumiza ma siginecha ndi kukhazikika kopitilira muyeso kudzera pamakina awiri otchinga kunja.

Kuti mupeze chizindikiro cha electrocardiogram (ECG), wowunika wodwala amagwiritsa ntchito njira zisanu zotsogola za ECG.Imagwira ma sign a bioelectric ndikuwasintha kukhala zotulutsa za digito.Chowunikira cha HM10 chimakhala ndi njira zisanu zopezera ECG ndi chitsogozo chimodzi choyendetsedwa, chopereka chiwonetsero cholondola komanso chokhazikika cha mawonekedwe a mafunde a ECG pamodzi ndi chidziwitso cha kupuma ndi kugunda kwa mtima.Kupititsa patsogolo kukhazikika kwa kufalikira kwa ma siginecha, gawo la ECG limagwiritsa ntchito njira yolumikizira mapini khumi ndi awiri ndikuyika mapini olekanitsa kuti atetezedwe, kupititsa patsogolo kudalirika kwa kutumiza ma sign.

Kupita patsogolo kwaukadaulo kowunikiraku kumagwira ntchito yofunika kwambiri pakuwonetsetsa kukhazikika kwa muyeso mwa owunika odwala.Pogwiritsa ntchito njira zapamwamba kwambiri za photoplethysmography ndi njira zolumikizirana ndi thupi, chowunikiracho chimachepetsa kusokoneza kwa ma sign ndikupeza zotsatira zokhazikika komanso zolondola.Ukadaulo uwu umathandizira kuti oyang'anira azigwira ntchito modalirika m'malo osiyanasiyana, kupatsa akatswiri azachipatala chithandizo chodalirika cha data kuti athe kuunika bwino kwa odwala komanso kupanga zisankho zachipatala.

Posankha woyang'anira wodwala, kukhazikika kwa miyeso kuyenera kuganiziridwa kwambiri.Opanga amagwiritsa ntchito matekinoloje ofunikira monga dual-wavelength photoplethysmography ndi njira zolumikizirana ndi thupi kuti zitsimikizire kukhazikika kwa mpweya wa okosijeni m'magazi ndi miyeso ya chizindikiro cha ECG.Kupititsa patsogolo uku kumatsimikizira magwiridwe antchito odalirika komanso olondola.Sankhani chowunikira chomwe chimayika patsogolo kukhazikika kwa kuyeza kuti mupereke zotsatira zabwino zachipatala.
