Mukupera kwema1990, zvidzidzo zvakawanda zvakaitwa kuti zviongorore kururamisa kwevasiri-nyanzvi, vanotanga kupindura, varapi vehutano uye kunyange vanachiremba mukuongorora chete kuvapo kwepulse.Mune imwe ongororo, chiyero chekubudirira kwekuzivikanwa kwepulse kwakadzikira se45%, nepo mune imwe ongororo, vana chiremba vadiki vakapedza avhareji yemasekonzi gumi nemasere kuti vazive pulse.
Imhaka yezvikonzero izvi kuti maererano nekurudziro yeInternational Resuscitation Committee, Komiti yeBritish Resuscitation Committee neAmerican Heart Association yakadzima cheki chenguva dzose sechiratidzo chehupenyu kubva pakudzidziswa kwerubatsiro rwekutanga kwakagadziridzwa muna 2000.
Asi kuongorora kurova kwemwoyo kunokosha chaizvo, Sezvineiwo zviratidzo zvinokosha zvinokosha, kuziva kana kurova kwemunhu akuvara kuri pakati penguva dzose kunogona kutipa ruzivo rwakakosha;
Kana kuputika kwevakakuvadzwa kusiri mukati mezvikamu izvi, zvinogona kutotungamirira kune mamwe matambudziko.Kana mumwe munhu akamhanya achitenderera, isu tinotarisira kupuruzira kwavo kusimuka.Tinodawo kuti dzipise, dzitsvukire uye dzifeme nekukurumidza.Kana vasina kumhanya-mhanya, asi vachipisa, dzvuku, kupfupika kwekufema uye kukurumidza kuputika, tinogona kunge tine dambudziko, iro rinogona kuratidza sepsis.Kana vakakuvara;inopisa, tsvuku, inononoka uye yakasimba pulse, izvi zvinogona kuratidza kukuvara kwemukati mukati.Kana vakakuvara, kutonhora, kucheneruka uye vaine kurova kwekukurumidza, vanogona kunge vaine hypovolemic shock.
Isu tinoshandisa pulse oximeter:Pulse oximeterchishandiso chidiki chekuongorora chinonyanya kushandiswa kuona kuzara kweokisijeni yeropa yevakakuvara, asi inogona zvakare kuratidza kupuruzira kwevakakuvara.Neimwe yadzo, hatifanirwe kutambisa nguva kusvika kune vakakuvadzwa uye kunzwa kurovera kwakanyanya.
Iyo pulse oximetry nzira inoyera huwandu hweokisijeni inotakurwa muropa sechikamu.Shandisa pulse oximeter kuyera pamunwe wako.Kuyera uku kunonzi Sp02 (peripheral oxygen saturation), uye ifungidziro yeSp02 (arterial oxygen saturation).
Hemoglobin iri mumasero matsvuku eropa inotakura okisijeni (dikidiki inonyungudika muropa).Morekuru rimwe nerimwe rehemoglobin rinogona kutakura mamorekuru mana eokisijeni.Kana hemoglobin yako yose yakasungirirwa kumamolekemu mana eokisijeni, ipapo ropa rako richa "zadzwa" neokisijeni, uye SpO2 yako ichava 100%.
Vanhu vazhinji havana 100% oksijeni saturation, saka huwandu hwe 95-99% hunoonekwa sehumwe.
Chero indekisi iri pasi pe95% inogona kuratidza hypoxia-hypoxic okisijeni ichapinda mumatishu.
Kuderera kweSpO2 ndiyo inonyanya kuvimbika chiratidzo cheakakuvara's hypoxia;kuwedzera kwehuwandu hwekufema kunobatana ne hypoxia, asi kune uchapupu hwokuti kubatana uku hakuna kusimba zvakakwana (uye kunyange kuripo muzviitiko zvose) kuva chiratidzo che hypoxia.
Thepulse oximeterchishandiso chekukurumidza chekuongorora chinokutendera kuyera uye kutarisa mwero weokisijeni weakakuvara.Kuziva kuti yakakuvara Sp02 inogona zvakare kukugonesa iwe kupa iyo yakaringana huwandu hweokisijeni mukati mehunyanzvi renji.
Kunyange kana kuzara kweokisijeni yeropa iri mukati mehutano hwemazuva ose, SpO2 inoderedzwa ne3% kana kupfuura, inova chiratidzo chekuongorora kwakakwana kwemurwere (uye chiratidzo che oximeter), nokuti iyi inogona kuva uchapupu hwekutanga hwechirwere chechirwere.
