Munguva pfupi yapfuura, pulse oximetry (SpO2) yawana kutariswa kuri kuwedzera kubva kuruzhinji nekuti vamwe vanachiremba vanokurudzira kuti varwere vakaonekwa vaine COVID-19 vatarise mazinga avo eSpO2 kumba.Naizvozvo, zvine musoro kuti vanhu vazhinji vabvunze "Chii SpO2?"kekutanga.Usanetseke, ndapota verenga uye isu tichakutungamira kuti chii chinonzi SpO2 uye kuti unoiyera sei.
SpO2 inomirira ropa reoxygen saturation.Vakuru vane hutano vanowanzova ne95% -99% kuzara kweropa, uye chero kuverenga pasi pe89% kunowanzokonzera kunetseka.
A pulse oximeter inoshandisa mudziyo unonzi pulse oximeter kuyera huwandu hweokisijeni mumasero matsvuku eropa.Chishandiso chicharatidza chakoSpO2sechikamu.Vanhu vane zvirwere zvemapapu senge chronic obstructive pulmonary disease (COPD), asima kana mabayo, kana vanhu vanombomira kufema panguva yekurara (apnea yekurara) vanogona kunge vaine mazinga eSpO2 akaderera.Pulse oximetry inogona kupa yambiro yekutanga kumatambudziko mazhinji ane chekuita nemapapu, ndosaka vamwe varapi vachikurudzira kuti varwere vavo veCCIDID-19 vanogara vachitarisa SpO2 yavo.Kazhinji kazhinji, varapi vanowanzoyera SpO2 muvarwere panguva yekuongororwa kwakapusa, nekuti iyi inzira inokurumidza uye iri nyore yekuratidza matambudziko angangove ehutano kana kubvisa zvimwe zvirwere.
Kunyange zvazvo zvave zvichizivikanwa kubvira kuma1860 kuti hemoglobin ndicho chikamu cheropa chinoendesa oxygen kumuviri wose, zvichatora makore 70 kuti zivo iyi ishandiswe zvakananga mumuviri womunhu.Muna 1939, Karl Matthes akagadzira piyona wemazuva ano pulse oximeters.Akagadzira mudziyo unoshandisa mwenje mutsvuku neinfrared kuti urambe uchiyera kuzara kweokisijeni munzeve yemunhu.Munguva yeHondo Yenyika II, Glenn Millikan akagadzira yekutanga inoshanda yekushandisa iyi tekinoroji.Kuti agadzirise dambudziko rekudzima kwemagetsi emutyairi wendege panguva yekufamba-famba kwepamusoro-soro, akabatanidza oximeter yenzeve (izwi raakagadzira) kune imwe nzira inopa zvakananga okisijeni kumasiki yemutyairi apo kuverenga kweokisijeni kunoderera zvakanyanya .
Nihon Kohden's bioengineer Takuo Aoyagi akagadzira yekutanga chaiyo pulse oximeter muna 1972, paakanga achiedza kushandisa nzeve oximeter kuteedzera dilution yedhayi kuyera kubuda kwekurova kwemoyo.Paaiedza kutsvaga nzira yekurwisana nemagetsi emagetsi anokonzerwa nemhepo yenyaya, akaziva kuti ruzha rwakakonzerwa nekuputika rwakakonzerwa zvachose nekuchinja kwekuyerera kweropa.Mushure memakore anoverengeka ekushanda, akakwanisa kugadzira mudziyo wewavelength maviri unoshandisa shanduko mukuyerera kweropa kuyerera zvakanyanya kuyera mwero wekunyudzwa kweokisijeni muropa.Susumu Nakajima akashandisa tekinoroji iyi kugadzira yekutanga kuwanikwa kwekiriniki vhezheni, uye akatanga kuyedza kuvarwere muna 1975. Yakanga isiri kutozosvikira ma1980 ekutanga apo Biox yakaburitsa yekutanga yakabudirira kutengeserana pulse oximeter yemusika wekuchengetedza kufema.Pakazosvika 1982, Biox yakagamuchira mishumo yekuti midziyo yavo yakashandiswa kuyera kuzara kweokisijeni yeropa revarwere vakavhiyiwa panguva yekuvhiyiwa.Kambani yakakurumidza kutanga basa uye yakatanga kugadzira zvigadzirwa zvakagadzirirwa chaizvo vanesthesiologists.Kushanda kwekuyera SpO2 panguva yekuvhiyiwa kwakakurumidza kuzivikanwa.Muna 1986, American Society of Anesthesiologists yakagamuchira intraoperative pulse oximetry sechikamu chemaitiro ayo ekutarisira.Nekuvandudzwa uku, pulse oximeters yakashandiswa zvakanyanya mune mamwe madhipatimendi echipatara, kunyanya mushure mekuburitswa kwekutanga kuzvimiririra kwemunwe pulse oximeter muna 1995.
Kazhinji kutaura, nyanzvi dzekurapa dzinogona kushandisa marudzi matatu emidziyo kuyera iyoSpO2yemurwere: multi-function kana multi-parameter, murwere tarisisa, pamubhedha kana ruoko-wakabatwa pulse oximeter kana fingertip pulse oximeter.Mhando mbiri dzekutanga dzevatariri dzinogona kuramba dzichiyera varwere, uye dzinogona kuratidza kana kudhinda girafu rekuchinja mukuzara kweokisijeni nekufamba kwenguva.Spot-check oximeters anonyanya kushandiswa kutora snapshot kuzara kwemurwere panguva yakatarwa, saka aya anonyanya kushandiswa kuongororwa mumakiriniki kana mahofisi evanachiremba.
