Inkqubo ye-metabolic yomzimba womntu yinkqubo ye-biological oxidation, kwaye ioksijini efunekayo kwinkqubo ye-metabolic ingena egazini lomntu ngenkqubo yokuphefumla, kwaye idibanisa ne-hemoglobin (Hb) kwiiseli ezibomvu zegazi ukwenza i-oxyhemoglobin (HbO₂), ethi emva koko ihanjiswe emzimbeni womntu. Kwigazi elipheleleyo, ipesenteji yomthamo we-HbO₂ ebotshwe yi-oksijini ukuya kumandla okubopha iyonke ibizwa ngokuba yi-blood oxygen saturation SpO₂.

Ukuphonononga indima ye-SpO₂ yokubeka iliso ekuhloleni nasekuxilongweni kwesifo senhliziyo esizalwa yi-neonatal. Ngokweziphumo zeQela lokuSebenzana leSizwe lePathology yaBantwana, ukubeka iliso kwe-SpO₂ kuluncedo ekuhloleni kwangethuba abantwana abanesifo sentliziyo abazalwa nabo. Uvakalelo oluphezulu bubuchwephesha obukhuselekileyo, obungaphazamisiyo, obunokwenzeka nobunengqiqo, obufanele ukukhuthazwa nokusetyenziswa kwezonyango zokubelekisa.

Okwangoku, ukubekwa esweni kwe-pulse SpO₂ isetyenziswe ngokubanzi kwimisebenzi yeklinikhi. I-SpO₂ isetyenziswe njengesiqhelo esweni uphawu lwesihlanu olubalulekileyo kwizifo zabantwana. I-SpO₂ yabantwana abasanda kuzalwa ingabonakaliswa njengesiqhelo xa ingaphezulu kwe-95%, Ukufunyanwa kwe-SpO₂ yegazi elisanda kuzalwa kunokunceda abongikazi bafumane utshintsho kwimeko yabantwana ngexesha, kwaye bakhokele isiseko sonyango lwe-oksijini yeklinikhi.

Nangona kunjalo, ekubekeni iliso kwi-SpO₂ ye-neonatal, nangona ithathwa njengento engabonakaliyo, ekusebenziseni iklinikhi, kusekho iimeko zokulimala kweminwe okubangelwa ukubekwa esweni kwe-SpO₂ eqhubekayo. Kuhlalutyo lweemeko ze-6 zokubekwa esweni kwe-SpO₂ Kwidatha yokulimala kwesikhumba somunwe, izizathu eziphambili zishwankathelwa ngolu hlobo lulandelayo:

1. Indawo yokulinganisa isigulane ine-perfusion embi kwaye ayikwazi ukususa ubushushu benzwa ngokujikeleza kwegazi okuqhelekileyo;

2. Indawo yokulinganisa ingqindilili kakhulu; (umzekelo, iintende zabantwana abasanda kuzalwa iinyawo zabo ezingaphezulu kwe-3.5KG zityebe kakhulu, ezingafanelanga kulinganisa unyawo olusongelweyo)

3. Ukungaphumeleli ukujonga rhoqo i-probe kunye nokutshintsha indawo.

Ngoko ke, i-MedLinket iphuhlise i-sensor yokukhusela i-SpO₂ ngokugqithisileyo ngokusekwe kwimfuno yemarike. Esi sivamvo sinesivamvo sobushushu. Emva kokuhambelana nentambo ye-adapter ezinikeleyo kunye ne-monitor, inomsebenzi wokubeka iliso kwiqondo lokushisa elingaphezulu kwendawo. Xa isigulane sibeka iliso kwiqondo lokushisa kwesikhumba ngaphezu kwe-41 ℃, Inzwa iyakuyeka ukusebenza ngokukhawuleza. Ngexesha elifanayo, ukukhanya kwesalathisi se-SpO₂ ikhebula le-adapter likhupha ukukhanya okubomvu, kwaye i-monitor ikhupha isandi se-alamu, ebangela ukuba abasebenzi bezonyango bathathe amanyathelo afanelekileyo ukuphepha ukutshisa. Xa ukushisa kwesikhumba kwindawo yokubeka iliso yesigulane kwehla ngaphantsi kwe-41 ° C, i-probe iya kuqalisa kwakhona kwaye iqhubeke nokubeka iliso kwidatha ye-SpO₂. Ukunciphisa umngcipheko wokutshisa kunye nokunciphisa umthwalo wokuhlolwa rhoqo kwabasebenzi bezonyango.

Iinzuzo zemveliso:

1. Ukujongwa kobushushu obungaphezulu: Kukho inzwa yobushushu ekupheleni kweprobe. Emva kokuhambelana nekhebula le-adapter ezinikeleyo kunye nokubeka iliso, inomsebenzi wokubeka iliso kwindawo yokushisa, okunciphisa umngcipheko wokutshisa kunye nokunciphisa umthwalo wokuhlolwa rhoqo kwabasebenzi bezonyango;

2. Ukhululekile ngakumbi ukusebenzisa: indawo yeprobe yokusonga inxalenye encinci, kunye nokungena komoya kulungile;

3. Isebenza kakuhle kwaye iluncedo: uyilo lwe-V-shaped probe, ukubeka ngokukhawuleza indawo yokubeka iliso, uyilo lwesibambo sokudibanisa, ukudibanisa okulula;

4. Isiqinisekiso sokhuseleko: i-biocompatibility efanelekileyo, akukho latex;
