Umkhawulo wokulinganisa inzwa.

Umkhawulo wokulinganisa inzwa.

Uma ukunemba kwanoma isiphi isilinganiso kubonakala kungenangqondo, qala ngokuhlola izimpawu ezibalulekile zesiguli umhloli.enye indlela.Bese uhlola ukuthi ithuluzi lisebenza kahle yini.

Izilinganiso ezingalungile zingabangelwa:

Okungalungileukusetshenziswa noma ukusetshenziswa kwezinzwa;umsindo kagesi oyimvamisa ephezulu, njengaleyo evela kumishini yokuhlinzwa kagesi exhunywe ohlelweni;amazinga abalulekile we-hemoglobin engasebenzi (isb, i-carboxyhemoglobin noma i-methemoglobin);ukugxila okubalulekile kwe-hemoglobin engasebenzi, njenge-carboxyhemoglobin ne-methemoglobin;odayi be-intravascular njenge-indocyanine eluhlaza noma i-methylene eluhlaza okwesibhakabhaka;ukuchayeka ekukhanyeni ngokweqile njengezibani zokuhlinza (ikakhulukazi lezo ezinamalambu e-xenon), amalambu e-bilirubin, amalambu e-fluorescent, ukushisa kwe-infrared Ukukhanya noma ukukhanya kwelanga okuqondile (ukuchayeka kakhulu ekukhanyeni kungalungiswa ngokumboza inzwa ngezinto ezimnyama);ukunyakaza kwesiguli ngokweqile;ukushaya kwe-venous;I-SpO2 iphansi kakhulu;inzwa efakwe ngokungafanele noma indawo yokuxhumana nesiguli engalungile;, i-ductus arteriosus, noma isitho esifanayo ngaphakathi komkhumbi siya ku-inthanethi.Izinzipho ezingcolile noma i-nail polish noma izinzipho zokwenziwa.

Ukulahleka kwesignali ye-pulse kungenzeka ezimweni ezilandelayo:

inzwa iqine kakhulu;ukukhanya okukhulu okuvela emithonjeni yokukhanya njengezibani zokuhlinzwa, amalambu e-bilirubin, noma ukukhanya kwelanga;

Ikhafu lomfutho wegazi livuthele esithweni esifanayo lapho i- Inzwa ye-SpO2inamathiselwe;isiguli

I-Hypotension, i-vasoconstriction enamandla, i-anemia enzima, noma i-hypothermia;i-arterial occlusion proximal to sensor;isiguli ekuboshweni kwenhliziyo noma ukushaqeka
