Uzinzo lomlinganiselo luphawu olubalulekileyo lokuvavanya umgangatho wesigulane esibeka iliso.Kumlinganiso wokugcwala kweoksijini yegazi, umntu ojongayo usebenzisa i-dual-wavelength pulsatile photoplethysmography ubuchule.Ngokuhlalutya ukunyuswa okungafaniyo kokukhanya okubomvu kunye ne-infrared nge-oksijini ye-hemoglobin (HbO2) kunye ne-hemoglobin (Hb) egazini, amanqanaba okuzaliseka kwe-oksijini yegazi okwenyani abalwa.Ukuqinisekisa iziphumo zokulinganisa ezizinzile, i-monitor isebenzisa iimfuno eziphezulu zokukhutshwa kwe-LED kunye nokwamkela i-photodetector ukuphazamisa ukuphazamiseka.I-HM-10 ye-oximetry probe isebenzisa idizayini yoqhagamshelo lwe-10-pin ebonakalayo, eyenza ukukhuselwa okwahlukileyo kukuhanjiswa komqondiso kunye nozinzo oluphezulu ngomatshini wokukhusela wangaphandle we-pin-pin.

Ukufumana umqondiso we-electrocardiogram (ECG), isigulane sisebenzise inkqubo ye-ECG ehamba phambili emihlanu.Ibamba imiqondiso ye-bioelectric kwaye iguqulelwe kwiziphumo zedijithali.Imonitha ye-HM10 ineendlela ezintlanu zokufunyanwa kwe-ECG kunye nesikhokelo esinye esiqhutywayo, esibonelela ngomboniso ochanekileyo nozinzileyo weefomati zamaza e-ECG kunye nolwazi lokuphefumula kunye nentliziyo.Ukomeleza uzinzo lokuhanjiswa komqondiso, imodyuli ye-ECG isebenzisa indlela yoqhagamshelo lomzimba elinesibini elinesibini kwaye iphumeze ukwahlula isikhonkwane somqondiso wokukhusela, nokuphucula ngakumbi ukuthembeka kokuhanjiswa komqondiso.

Ezi nkqubela phambili zetekhnoloji ziqaqambile zidlala indima ebalulekileyo ekuqinisekiseni uzinzo lomlinganiselo kubahloli bezigulane.Ngokusebenzisa umgangatho ophezulu we-photoplethysmography kunye nobuchule bokudibanisa ngokomzimba, i-monitor inciphisa ngokufanelekileyo ukuphazamiseka komqondiso kwaye ifumana iziphumo ezizinzileyo nezichanekileyo zokulinganisa.Ezi teknoloji zenza ukuba i-monitor isebenze ngokuthembekileyo kwiindawo ezahlukeneyo, ukubonelela abaqeqeshi bezempilo ngenkxaso yedatha ethembekileyo yovavanyo olungcono lwesigulane kunye nokwenza izigqibo zonyango.

Xa ukhetha isigulane esweni, ukuzinza komlinganiselo kufuneka kuqwalaselwe kakhulu.Abavelisi basebenzisa iteknoloji eziphambili ezifana ne-double-wavelength photoplethysmography kunye neendlela zokudibanisa ngokomzimba ukuze kuqinisekiswe ukuzinza kwi-oksijeni yegazi kunye nemilinganiselo yesignali ye-ECG.Ezi nkqubela ziqinisekisa ukusebenza okuthembekileyo kunye nokuchaneka.Khetha imonitha ebeka phambili ukuzinza komlinganiselo ukuze kunikezelwe iziphumo zokhathalelo lwempilo olululo.
