He arotake pono tēnei mai i tētahi kaihoko i runga i a Amazon.

E mōhio ana tātou he tawhā nui te SpO₂ e whakaata ana i te mahi manawa o te tinana me te mea he noa te nui o te hāora, ā, ko te oximeter he taputapu e aroturuki ana i te āhua o te hāora i roto i te toto i roto i ō tātou tinana. Ko te hāora te pūtake o ngā mahi o te ao, ko te hypoxia te pūtake o ngā mate maha, ā, he maha ngā mate ka taea hoki te kore e ranea te tuku hāora. Ko te SpO₂i raro iho i te 95% he whakaata i te hypoxia ngawari. Ko te iti iho i te 90% he hypoxia nui, me rongoā wawe tonu. Ehara i te mea ko ngā kaumātua anake ka pāngia e te hypoxemia, engari he nui te ahotea hinengaro me te wā mahi me te wā okiokinga o te hunga o ēnei rā. He maha ngā wā ka puta te hypoxemia i ngā mahi hē. Ka pā kino te SpO₂ iti mō te wā roa ki te tinana tangata. Nō reira, me ine tonu te SpO₂ i roto i te tinana, ahakoa kua mahia ngā mahi tiaki.

Mō ngā oximeter, mō ngā kaiwhakamahi kāinga me ngā tohunga whakapakari tinana ngaio, ka whiriwhiri te nuinga o te tangata i ngā oximeter kawe here-maihao, nā te mea he tino ataahua, he iti, he ngāwari ki te kawe, ā, kāore e herea e te wā me te wāhi. He tino watea, he tere hoki. Ka whakamahia hoki ngā oximeter topenga maihao i roto i te maha o ngā wāhi hauora ngaio, engari he tino teitei ngā whakaritenga tika. Nō reira, ko te whakakore i ngā hapa tētahi o ngā mea matua mō te ine tika o te oximeter.

He hononga tata te tika o te oximeter ki te kaupapa hangarau ngaio o te oximeter. Ko ngā kaupapa hoahoa o ngā kaiwhakarato otinga oximeter o nāianei kei te mākete he rite tonu: te whakamahinga o te LED whero, te LED infrared me te hanganga photodiode o te ara iahiko pūoko SpO₂, me te ara iahiko taraiwa LED. I muri i te tukunga o te rama whero me te rama infrared mā te maihao, ka kitea e te ara iahiko tukatuka tohu, kātahi ka tukuna ki te kōwae ADC o te rorohiko iti maramara kotahi hei tatau anō i te ōrau o SpO₂. Ka whakamahia e rātou katoa ngā wāhanga tairongo mārama pēnei i te rama whero, te rama infrared LED me te photodiode hei ine i te tukunga o ngā matimati me ngā taringa. Heoi, ko ngā kaiwhakarato otinga oximeter he paerewa me ngā whakaritenga teitei ake mō te kaupapa he whakaritenga whakamātautau pakari ake, he uaua ake hoki. Haunga ngā tikanga whakamātautau tuku iho kua whakahuatia i runga ake nei, me whakamahi e rātou ā rātou ake hua kaupapa me ngā whakatauira oximeter ngaio. Ka whakaritea ngā raraunga ki te oximeter taumata hauora.

Kua rangahaua te oximeter i whakawhanakehia e MedLinket i roto i ngā hōhipera whai tohu. I roto i te rangahau kukū whakahaeretia, kua whakaūtia te SaO₂ o te whānuitanga ine o tēnei hua o te 70% ki te 100%. Ki te whakatauritea ki te uara SpO₂ uaua i inehia e te CO-Oximeter, ka whiwhihia he raraunga tika. Ka whakahaeretia te hapa SpO₂ i te 2%, ā, ka whakahaeretia te hapa pāmahana i te 0.1℃, ka taea ai te whakatutuki i te ine tika o te SpO₂, te pāmahana, me te pā. , Hei whakatutuki i ngā hiahia o te ine ngaio.

Mā te whiriwhiri i te otinga ine oximeter MedLinket e whai hua ana, e tika ana hoki i te mākete, e whakapono ana ahau ka tere te whiwhi i te manako o ngā kaiwhakamahi.
