Abantu baphefumula umoya nsuku zonke, ngoba umoya uqukethe umoya-mpilo, okuyisisekelo sokugcina izimpilo zabantu.I-hemoglobin encishisiwe equkethwe emizimbeni yabantu ihlangana nomoya-mpilo otholakala emaphashini ukuze kwakheke umoya-mpilo ne-hemoglobin.Umoya-mpilo uncibilika ku-plasma ukuze kugcinwe ukuqina kwamangqamuzana ezicubu.Inzwa ye-oxygen ingakala iphesenti le-hemoglobin egazini lomzimba womuntu egazini lonke.Okulandelayo kuchaza indima yenzwa ye-oxygen yegazi:
Inzwa komoyampilo wegazi ingakala ukugcwala komoyampilo egazini emzimbeni womuntu.Ukugcwala komoyampilo egazini kubhekisela kumaphesenti e-hemoglobin ene-oksijini egazini legazi labantu egazini.Ukugcwala komoyampilo egazini kuyinkomba ebalulekile yokulinganisa isiguli.Inzwa ye-oxygen yegazi ihlukaniswe yaba izimo ezihlukahlukene, okungukuthi uhlobo lomunwe, uhlobo lwe-earlobe kanye nohlobo lokunamathela ebunzini.Kungakhathaliseki ukuthi umumo unjani, umnyombo wenzwa ye-oksijeni yegazi usafana, owakhiwe ngamadivaysi akhipha ukukhanya kanye namadivayisi okwamukela.Idivayisi ekhipha ukukhanya kwenzwa yomoya-mpilo wegazi yenziwe ngeshubhu lokukhanya kwe-infrared, futhi isamukeli esithwebula isithombe senzwa ye-oxygen yegazi sithatha i-PIN photosensitive diode, eguqula isignali yokukhanya yesigameko etholiwe ibe isignali kagesi, futhi isebenzisa ubuchwepheshe obuphezulu ukuze yenze ishintshe.Lapho isetshenziswa, indawo yokwamukela iba nkulu, ukuzwela kuphezulu, ubumnyama bamanje buncane, futhi umsindo uphansi.Indlela yokushayela yenzwa yomoya-mpilo wegazi empeleni isebenzisa ama-diode amabili akhipha ukukhanya kanye neshubhu eyamukelayo ezwelayo ukuze ibone indlela yokulinganisa eyimigoqo ekabili ukuze kukale ukugcwala komoyampilo egazini.Ukusetshenziswa kwale ndlela yokushayela ukushaya kwenhliziyo akukwazi nje ukuthuthukisa okuphazima kweso Ngaphezu kokunciphisa ukusetshenziswa kwamandla, kungase futhi kunwebe impilo yesevisi yenkathi.Inzwa ye-oksijini yegazi iphinde yamukele indlela yokulinganisa i-optical, okuyindlela yokulinganisa i-oxygen yegazi eqhubekayo futhi engonakalisi, engeke ibangele ubuhlungu nemiphumela emibi emzimbeni womuntu.
