oxygen saturation (SaO2) iperesenti yehuwandu hweoxyhemoglobin (HbO2) yakasungwa neokisijeni muropa kusvika kuhuwandu hwehuwandu hwehemoglobin (Hb, hemoglobin) inogona kusungwa neokisijeni, kureva, kuwanda kweokisijeni muropa ropa.zvakakosha physiological parameters.
Ropa okisijeni saturation inomiririra hutano hwemuviri wemunhu uye inogona kuratidza hutano hwemunhu wekufema system uye yemoyo system.Inoita basa rinokosha mukudzivirira uye kuongororwa kwezvirwere zvevanhu.Nokudaro, kutarisa kuzara kweokisijeni yeropa kwakakosha zvikuru.physiological meaning.
Chirwere chekiriniki chisingaiti chekuyera kuzara kweokisijeni yeropa ndeyekushandisa chigunwe-cuff type photoelectric sensor, uye oksijeni saturation ye arterial blood inoshandiswa kutsiva kuzara kweokisijeni yehutu hwevanhu.Kutarisa arterial blood oxygen saturation kunogonawo kutakura oxygen kune oxyhemoglobin mumapapu.Inogona kuratidza zvakananga basa rekufema remapapu.Kuyera kukosha kwevanhu vane hutano kunofanira kuva pamusoro pe95%, uye inogona kunge yakaderera kune vanoputa.Zvinowanzoonekwa kuti isingasviki 90% chiratidzo chenjodzi.
Kana iyo okisijeni yeropa iri mumuviri wemunhu ikaderedzwa, zviri nyore kukonzera zviratidzo zvakaita sekuneta uye kurara, kushaya simba, uye kurasikirwa nekuyeuka.Kwenguva refu kusakwana kweokisijeni yeropa inokonzeresa kukanganisa kuhuropi, moyo uye dzimwe nhengo.
Uropi ndiyo inonyanya kunzwisiswa yenheyo system kune hypoxia.Mild hypoxia muuropi inokonzeresa zviratidzo zvakadai sekuneta mupfungwa, kusakwanisa kuisa pfungwa, uye kurasikirwa nendangariro.Kana uropi hukaramba husina oxygen, huchatungamirira kurufu rwemasero etsinga, uye zviri nyore kukanganisa kushanda kwemamwe maitiro, izvo zvinoisa upenyu pangozi.Kana iyo hypoxia ikawedzera, kana acute hypoxia, pfungwa yevanhu yekutungamirira uye kuwirirana kwemotokari inorasika zvishoma nezvishoma, uye mumatambudziko akaoma, kukanganisa kwekuziva, coma, uye kunyange rufu ruchaitika.
Kufanana neuropi, mwoyo inhengo inodya oksijeni yakawanda uye ine mwero wemetabolism wakakwira.Kana mwoyo uri munyoro hypoxic, kutsiva kwemoyo kunowedzera kutanga, kurova kwemoyo uye kubuda kwemoyo kunowedzera, circulatory system inotsiva kushaikwa kweokisijeni yemukati mune hyperdynamic state, uye panguva imwechete inoburitsa kuyerera kweropa, cerebral uye coronary midziyo. .Kuwedzera kusarudzwa kuti kuve nechokwadi chekupa ropa rakakwana kunokonzeresa zviratidzo senge heart beat rhythm disorder uye palpitations.Kana mwoyo ukaramba usingagumi hypoxia, nekuda kwekuunganidza kwe subendocardial lactic acid, ATP synthesis inoderera, zvichiita kuti myocardial depression iite, zvichiita kuti bradycardia, kupera nguva isati yakwana, kuderera kweropa uye kubuda kwemwoyo, pamwe chete nearrhythmias yakadai se ventricular fibrillation uye kunyange ventricular. fibrillation.asystole.Kana mwoyo wakanyanya hypoxic, zvinotungamirira kune myocardial hypertrophy uye cardiac volume hypertrophy, kushanda kwemoyo kunoderera, uye kukanganisa kwemoyo kuchaitika nyore nyore..
Pamusoro pezvo, tsvakiridzo yakabatana kunze kwenzvimbo yezvokurapa yakasimbisa kuti kuongorora kuzara kweokisijeni muropa kune zvakakosha kutungamira kukosha kwekutungamira kurapwa kwechirwere chemoyo uye kufungidzira kufungidzira.
Kuti udzivise kukuvadzwa kwakasiyana kwemuviri kunokonzerwa ne hypoxia, zvakakosha zvikuru kutarisa kuzara kweokisijeni yeropa muhupenyu hwezuva nezuva.Kubva pakubuda kwenzira yekutarisa kuzara kweokisijeni yeropa kusvika ikozvino, pulse oximeter yakashandiswa zvakanyanya mumakiriniki ekudzidzira nekuda kwezvakanaka zvayo zvezvisina-invasive, zvakachengeteka uye zvakavimbika, zviri nyore kushandisa, zvinobudirira, zvinopfuurira uye panguva, uye zvakachipa.Yakava midziyo yakakosha yekurapa yekurapa mukamuri yekukurumidzira, imba yekuvhiya uye imba yekuchengetera zvakanyanya yechipatara.
Semuenzaniso, mukamuri yekukurumidzira, mucherechedzo weokisijeni weropa unogona kuramba uchitarisa kuzara kweokisijeni yeropa yemurwere, uye wobva waona kupihwa kweokisijeni zvinoenderana nekuyerwa kweokisijeni yekuzadza kukosha kweropa, kuitira kuti ive nechokwadi chekuchengetedza uye kubudirira kuburitsa kweokisijeni.
Muimba yekuvhiya, muchengeti weokisijeni weropa anogona kuramba achiyera kuzara kweokisijeni, kunyanya kuvarwere vanorwara zvakanyanya uye maoparesheni asina kufema zvakanaka, anogona kukurumidza kupa murwere ropa reokisijeni nekukurumidza, kuitira kuti vanachiremba vatore matanho ekununura anoenderana nekukurumidza.Mukamuri yekutarisisa, iyo yeropa okisijeni yekutarisa inogona kuseta inoenderana alarm zvinhu zvinoenderana nemamiriro anoenderana.Kana murwere akawanikwa aine apnea, low blood oxygen saturation value, fast heart rate, slow heart rate, etc. alarm inoenderana.
Pamusoro pezvo, zvakakoshawo zvakanyanya mukutarisisa kwevacheche, kunyanya kutarisisa kuzivikanwa kwe hyperoxia kana hypoxemia muvacheche uye vacheche vasati vasvika, uyezve gadzirisa kupihwa kweokisijeni yemidziyo yekupa okisijeni munguva chaiyo zvichienderana nemhedzisiro yekutarisa kudzivirira kunetsa. achangozvarwa.kukuvadzwa kuuropi, maziso, nemapapu evana.Panguva imwecheteyo, akawanda uye akawanda eimba anopfeka oximeter auyawo mukutarisa kwevanhu, uye anoshandiswa zvakanyanya mukuongorora, kuongorora, kuzvitonga uye zvichingodaro.
Semuenzaniso, kutarisa mamiriro ekuzara kweokisijeni muropa munguva yekunzwisisa hurongwa hwekufema hwemushandisi uye hutano hwemoyo, kuitira kuti uongorore kana vane hypoxemia nekukurumidza sezvinobvira, kuitira kudzivirira zvinobudirira kana kuderedza kufa netsaona kunokonzerwa ne hypoxia.
Uye zvakare, iyo oximeter inogona zvakare kushandiswa kuongororwa kwekumedza kusagadzikana, kuongororwa kwehope apnea syndrome, uye kuongorora kuyerwa kwegasi reropa.Chekupedzisira, iyo oximeter yepamba zvakare ine anotevera ekuzvitonga mabasa - senge nhungamiro yeokisijeni kurapwa, uye varwere vane matambudziko asingaperi ekufema vanogona kazhinji kuzvitonga pamba.
Pamusoro pezvo, mamonitor eokisijeni eropa anoshandiswawo zvakanyanya mukutsvagisa kwekiriniki yekurapa uye mamwe minda.Semuenzaniso, mukudzidza kwekurara kufema kufema kweokisijeni, kutarisisa kweropa oxygen saturation kunoshandiswa kuona kana murwere aine apnea syndrome kana husiku oxygen saturation.Low saturation uye mamwe mamiriro, kuongororwa kwekupedzisira kwechirwere chisingaperi chinobstructive tracheal.
Inogona zvakare kushandiswa mukutsvagisa kwemitambo hutano hwevanhu uye inoita basa rakakosha mune mamwe akawanda minda senge: mauto, aerospace uye zvichingodaro.Mune ramangwana, inotakurika yeropa oxygen saturation monitors ichashandiswa zvakanyanya mukuchengetedza hutano hwepamba uye hutano hwenharaunda, izvo zvichave zvakakosha mukudzivirira kwechirwere chevanhu uye kuongororwa.Mutsvagiridzo nekuvandudza zano reoximeter, Narigmed, yakazvipira kuenderera mberi nekuvandudza kuyerwa kweiyo oximeter, ichienderera mberi nekugadzirisa iyo isina kusimba perfusion kuita uye anti-exercise kuita, uye kutarisira kuunza nhau dzakanaka kune vanhu vazhinji, Narigmed blood oxygen tekinoroji yakazvimiririra. kodzero dzepfuma yehungwaru, uye mukufemerwa kusina simba PI = 0.025 % Inogona kuramba ichichengetedza kurongeka kweokisijeni yeropa uye kuyerwa kwepulse pasi pasi pe-ultra-low weak perfusion uye imwe frequency yekumisikidza kufamba uye kufamba zvisina tsarukano, izvo pasina mubvunzo mutungamiri pakati peChinese kurapwa. makambani emidziyo.
