Umda womlinganiselo wenzwa.

Umda womlinganiselo wenzwa.

Ukuba ukuchaneka kwawo nawuphi na umlinganiselo kubonakala kungenangqiqo, okokuqala jonga iimpawu ezibalulekileyo zesigulana zijongwe ngumvavanyi.enye indlela.Emva koko khangela ukuba isixhobo sisebenza ngokufanelekileyo.

Imilinganiselo engachanekanga inokubangelwa:

Ayifanelekangaukusetyenziswa okanye ukusetyenziswa kwabenzi boluvo;ingxolo ephezulu yombane, efana nesixhobo sotyando lombane oluqhagamshelwe kwisixokelelwano;amanqanaba abalulekileyo e-hemoglobin engasebenziyo (umzekelo, i-carboxyhemoglobin okanye i-methemoglobin);Uxinzelelo olubalulekileyo lwe-hemoglobin engasebenziyo, njenge-carboxyhemoglobin kunye ne-methemoglobin;iidayi ze-intravascular ezifana ne-indocyanine eluhlaza okanye i-methylene blue;ukubonakaliswa kokukhanya okugqithisileyo okufana nezibane zokuhlinzwa (ingakumbi ezo zinezibane ze-xenon), izibane ze-bilirubin, izibane ze-fluorescent, ukufudumeza kwe-infrared Ukukhanya okanye ukukhanya kwelanga ngqo (ukukhanya okugqithiseleyo ekukhanyeni kunokulungiswa ngokugubungela inzwa ngezinto ezimnyama);ukunyakaza kwesigulane ngokugqithisileyo;ukubetha kwe-venous;I-SpO2 iphantsi kakhulu;inzwa engafakwanga ngokufanelekileyo okanye indawo yokunxibelelana nesigulane engalunganga;, i-ductus arteriosus, okanye ilungu elifanayo ngaphakathi kwenqanawa liya kwi-intanethi.Izikhonkwane ezingcolileyo okanye i-nail polish okanye iinzipho ezenziweyo.

Ukulahlekelwa ngumqondiso we-pulse kungenzeka kwezi meko zilandelayo:

isivamvo siqine kakhulu;ukukhanya okugqithisileyo okuvela kwimithombo yokukhanya efana nezibane zotyando, izibane ze-bilirubin, okanye ukukhanya kwelanga;

Ikhafu yoxinzelelo lwegazi ivuthelwe kwilungu elinye eliya kulo Uluvo lwe-SpO2iqhotyoshelweumguli

I-Hypotension, i-vasoconstriction enzima, i-anemia enzima, okanye i-hypothermia;i-arterial occlusion proximal to sensor;isigulana ekubanjweni kwentliziyo okanye ukothuka
