ʻO ke kaʻina hana metabolic o ke kino o ke kanaka he kaʻina hana hoʻoheheʻe biological, a ʻo ka oxygen i koi ʻia i ke kaʻina metabolic e komo i ke koko o ke kanaka ma o ka ʻōnaehana hanu, a hui pū me ka hemoglobin (Hb) i loko o nā ʻulaʻula ʻulaʻula e hana i ka oxyhemoglobin (HbO₂), ka mea. a laila lawe ʻia i ke kino kanaka. I loko o ke koko holoʻokoʻa, ua kapa ʻia ka pākēneka o ka hiki HbO₂ i hoʻopaʻa ʻia e ka oxygen i ka nui paʻa paʻa i kapa ʻia ʻo ke koko oxygen saturation SpO₂.

No ka ʻimi ʻana i ke kuleana o ka nānā ʻana o SpO₂ i ka nānā ʻana a me ka ʻike ʻana i ka maʻi puʻuwai congenital neonatal. Wahi a nā hopena o ka National Pediatric Pathology Collaborative Group, pono ka nānā ʻana o SpO₂ no ka nānā mua ʻana i nā keiki me ka maʻi puʻuwai congenital. ʻO ka ʻike kiʻekiʻe kahi ʻenehana ʻike palekana, non-invasive, hiki a kūpono hoʻi, i kūpono i ka hoʻolaha a hoʻohana ʻia i nā obstetrics clinical.

I kēia manawa, ua hoʻohana nui ʻia ka nānā ʻana o ka pulse SpO₂ i ka hana lapaʻau. Ua hoʻohana ʻia ʻo SpO₂ ma ke ʻano he nānā maʻamau o ka hōʻailona koʻikoʻi ʻelima i nā pediatrics. Hiki ke hōʻike ʻia ka SpO₂ o nā keiki hānau hou ma ke ʻano maʻamau inā ʻoi aku lākou ma luna o 95%, ʻO ka ʻike ʻana o SpO₂ o ke koko hānau hou e hiki ke kōkua i nā kahu hānai e ʻike i nā loli i ke kūlana o nā keiki i ka manawa, a alakaʻi i ke kumu no ka lāʻau lapaʻau oxygen.

Eia nō naʻe, i ka nānā ʻana i ka SpO₂ neonatal, ʻoiai ua manaʻo ʻia ʻo ia he nānā non-invasive, i ka hoʻohana ʻana i ka lāʻau lapaʻau, aia nō nā hihia o ka hōʻeha manamana lima ma muli o ka nānā mau ʻana iā SpO₂. I ka nānā ʻana o 6 mau hihia o ka nānā ʻana o SpO₂ I ka ʻikepili o nā ʻeha ʻili manamana lima, ua hōʻuluʻulu ʻia nā kumu nui penei:

1. ʻAʻole hiki i ka mea maʻi ke ana ʻana i ka perfusion maikaʻi ʻole a ʻaʻole hiki ke lawe i ka wela sensor ma o ke kahe koko maʻamau;

2. He mānoanoa loa ke kahua ana; (no ka laʻana, ʻoi aku ka mānoanoa o nā kapuaʻi o nā keiki hānau hou a ʻoi aku ko lākou mau wāwae ma mua o 3.5KG, ʻaʻole kūpono ke ana ʻana i nā wāwae i ʻōwili ʻia)

3. ʻAʻole e nānā mau i ka probe a hoʻololi i ke kūlana.

No laila, ua hoʻomohala ʻo MedLinket i kahi sensor SpO₂ pale i ka wela ma muli o ka noi mākeke. He ʻike wela ko kēia ʻike. Ma hope o ka hoʻohālikelike ʻana me kahi uwea adapter i hoʻolaʻa ʻia a me kahi mākaʻikaʻi, loaʻa iā ia kahi hana nānā ʻana ma luna o ka wela. Ke ʻoi aku ka mahana o ka ʻili o ka mea maʻi ma mua o 41 ℃, e pau koke ka hana. I ka manawa like, hoʻopuka ke kukui hōʻailona o ka SpO₂ adapter cable i ke kukui ʻulaʻula, a hoʻopuka ka mea nānā i kahi leo hoʻāla, e koi ana i nā limahana lapaʻau e hana i nā manawa kūpono e pale ai i ke ahi. Ke hāʻule ka mahana o ka ʻili o ka wahi mākaʻikaʻi o ka mea maʻi ma lalo o 41°C, e hoʻomaka hou ka ʻimi a hoʻomau i ka nānā ʻana i ka ʻikepili SpO₂. E ho'ēmi i ka pilikia o ke kuni a hoʻemi i ke kaumaha o ka nānā mau o nā limahana lapaʻau.

Nā mea maikaʻi o ka huahana:

1. Ka nānā 'ana i ke ana wela: Aia ka 'ike wela ma ka hopena o ka 'imi. Ma hope o ka hoʻohālikelike ʻana me kahi kaula adapter i hoʻolaʻa ʻia a me ka nānā ʻana, loaʻa iā ia kahi hana nānā ʻana i ka wela wela, e hōʻemi ana i ka hopena o ke ahi a hoʻemi i ke kaumaha o ka nānā mau ʻana o nā limahana lapaʻau;

2. ʻOi aku ka ʻoluʻolu o ka hoʻohana ʻana: ʻoi aku ka liʻiliʻi o ka wahi o ka ʻāpana hoʻopaʻa ʻana i ka ʻimi noiʻi, a ua maikaʻi ka permeability o ka ea;

3. Maikaʻi a maʻalahi: V-like probe design, hoʻonohonoho wikiwiki i ke kūlana nānā, hoʻolālā lima hoʻopili, pili maʻalahi;

4. Ka palekana palekana: maikaʻi biocompatibility, ʻaʻohe latex;
