Pulse oximetersyakashandiswa kuongorora mamiriro eokisijeni yevarwere munzvimbo dzakasiyana-siyana dzekiriniki dzave dzakawanda uye dzinozivikanwa midziyo yekutarisa.Inopa kuenderera mberi, kusingapindi kwekutarisa kwehemoglobin oxygen saturation muropa re arterial.Imwe neimwe pulse wave inovandudza mhedzisiro yayo.
Pulse oximeters haipe ruzivo nezve hemoglobin concentration, kubuda kwemoyo, kugona kweokisijeni kuendesa kumatishu, kushandiswa kweokisijeni, oxygenation, kana kukwana kwemhepo.Nekudaro, ivo vanopa mukana wekuona nekukasira kutsauka kubva kukutanga kweokisijeni yemurwere, sechiratidzo chekunyevera kuvarapi kubatsira kudzivirira mhedzisiro yekupererwa uye kuona hypoxemia isati yaitika osis.
Zvave zvichikurudzirwa kuwedzera kushandiswa kwepulse oximeterskazhinji mawadhi anogona kuita kuti ive yakajairika sema thermometers.Zvisinei, zvinoshumwa kuti vashandi vane ruzivo rushoma rwekushanda kwemichina, uye ruzivo rushoma rwebasa rekushanda remichina uye zvinhu zvinogona kukanganisa kuverenga.
Kuenzaniswa nehemoglobin yakaderedzwa, pulse oximeters inogona kuyera kutorwa kweavelengths chaiyo yechiedza mune oxidized hemoglobin.Arterial oxygenated blood yakatsvuka nekuda kwehuwandu hweokisijeni hemoglobin yainayo, iyo inobvumira kuti itore mamwe mafungu echiedza.Iyo oximeter probe ine maviri-light-emitting diodes (LED) kune rimwe divi re probe, imwe tsvuku uye imwe infrared.Iyo probe inoiswa pachikamu chakakodzera chemuviri, kazhinji chigunwe kana kwenzeve, uye iyo LED inoendesa kureba kwechiedza kune iyo photodetector kune rumwe rutivi rwekuferefeta kuburikidza neinopuruzira arterial ropa.Oxyhemoglobin inotora chiedza che infrared;kuderedza hemoglobin kunoguma nechiedza chitsvuku.Iyo pulsatile arterial ropa mu systole inoita kuti oxygenated hemoglobin iyerere munyama, inotora yakawanda infrared mwenje, uye ichibvumira kushoma mwenje kusvika kune photodetector.Kuzadzwa kweokisijeni muropa ndiko kunoratidza mwero wekutorwa kwechiedza.Mhedzisiro yacho inogadziriswa kuita yedhijitari kuratidzwa kweokisijeni saturation pane oximeter skrini, inomiririrwa neSpO2.
Kune vazhinji vanogadzira uye mhando dze pulse oximeters.Yakawanda inopa inoonekwa yedhijitari waveform kuratidza, inonzwika arterial kurohwa uye kurova kwemoyo, uye akasiyana masensa kuti aenderane nevanhu vezera, saizi kana uremu.Sarudzo inobva pane zvigadziriso zvinoishandisa.Vese vashandi vanoshandisa pulse oximeters vanofanirwa kunzwisisa basa rayo uye mashandisiro akakodzera.
Arterial blood gas analysis yakanyatsojeka;zvisinei, pulse oximetry inofungidzirwa kuti yakarurama zvakakwana nokuda kwezvinangwa zvakawanda zvekliniki nekuda kwemiganhu yakaonekwa.
Mamiriro evarwere-Kuverenga mutsauko pakati pecapillaries uye isina chinhu capillaries, oximetry inoyera kunyudzwa kwechiedza kweakawanda pulses (kazhinji mashanu).Kuti uone kuyerera kweropa kuyerera, mvura yakakwana inofanira kuitwa munzvimbo inotariswa.Kana peripheral pulse yemurwere isina simba kana kuti isipo, iyopulse oximeterkuverenga kunenge kusina kururama.Varwere vari panjodzi yakanyanya ye hypoperfusion ndeavo vane hypotension, hypovolemia, uye hypothermia, uye avo vari mukusungwa kwemoyo.Vanhu vane dzihwa asi kwete hypothermia vanogona kunge vaine vasoconstriction muminwe yavo nezvigunwe uye zvinogona kukanganisa kuyerera kweropa.
Kana iyo probe yakagadziriswa zvakasimba, kwete-arterial pulsations inogona kuonekwa, zvichiita kuti venous pulsations mumunwe.Venous pulsation inokonzerwawo nekurudyi-side moyo kutadza, tricuspid regurgitation, uye tourniquet yeropa rekumanikidza cuff pamusoro pe probe.
Arrhythmia yemoyo inogona kukonzera mhedzisiro yekuyerwa isiriyo, kunyanya kana paine yakakosha apex / bone kushomeka.
Intravenous dhayi inoshandiswa mukuongorora uye hemodynamic bvunzo inogona kukonzera fungidziro isiriyo yeokisijeni saturation, kazhinji yakaderera.Migumisiro yeganda pigmentation, jaundice, kana yakakwirira bilirubin mazinga anofanirawo kufungwa.
Kushandiswa kwakarurama kwepulse oximetry kuyerwa kunosanganisira kwete kungoverenga kuratidzwa kwedhijitari, asiwo zvakawanda, nokuti havasi varwere vose vane SpO2 yakafanana vane okisijeni yakafanana muropa.Kuzadzwa kwe97% kunoreva kuti 97% yehemoglobin yakazara mumuviri yakazadzwa nemamorekuru eokisijeni.Nokudaro, kuzara kweokisijeni kunofanira kutsanangurwa mumamiriro ehuwandu hwehuwandu hwehemoglobin yemurwere.Chimwe chinhu chinokanganisa kuverenga kweoximeter ndechekuti hemoglobin inosunga sei kuokisijeni, iyo inogona kusiyana nekuchinja kwemamiriro akasiyana ehupenyu.
