Chiyero cheokisijeni yeropa (arterial blood oxygen content) inoratidza mwero weokisijeni uri muropa unoyerera nemutsinga dzemuviri.Iyo ABG bvunzo inoshandisa ropa rakatorwa kubva mutsinga, iyo inogona kuyerwa isati yapinda munyama yemunhu.Ropa richaiswa mumuchina weABG (blood gas analyzer), iyo inopa mazinga eokisijeni yeropa nenzira yeokisijeni chikamu chekumanikidza (oxygen partial pressure).
Hyperoxaemia inowanzoonekwa pachishandiswa bvunzo yeABG, iyo inotsanangurwa semazinga eokisijeni eropa pamusoro pe120 mmHg.Yakajairika arterial oxygen pressure (PaO2) yakayerwa uchishandisa arterial blood gas (ABG) bvunzo ingangoita 75 kusvika 100 mmHg (75-100 mmHg).Kana chiyero chiri pasi pe75 mmHg, chirwere ichi chinowanzonzi hypoxemia.Mazinga ari pasi pe60 mmHg anoonekwa seakaderera zvakanyanya uye anoratidza kudiwa kweokisijeni yekuwedzera.Okisijeni yekuwedzera inopiwa kuburikidza neokisijeni cylinder, iyo yakabatana nemhino kuburikidza nechubhu ine kana isina mask.
Chii chinofanira kunge chiri mukati meokisijeni?
Mwero yeokisijeni yeropa inogona kuyerwa zvakare uchishandisa chiridzwa chinonzi pulse oximeter.Iyo yakajairika oxygen level mupulse oximeter inowanzo 95% kusvika 100%.Isingasviki 90% yeropa okisijeni mwero yakaderera (hypoxemia).Hyperoxaemia inowanzoonekwa neABG test, iyo inotsanangurwa semazinga eropa okisijeni pamusoro pe120 mmHg.Izvi zvinowanzova muchipatara, apo murwere anotarisana nepamusoro pekuwedzera kweokisijeni kwenguva yakareba (3 kusvika maawa 10 kana kupfuura).
Chii chinoita kuti mwero weokisijeni muropa udzikire?
Ropa okisijeni mazinga anogona kuderera nekuda kwechero yeanotevera matambudziko:
Okisijeni iri mumhepo yakadzikira: Munzvimbo dzakakwirira-dzepamusoro dzakaita semakomo, mweya weokisijeni uri mumhepo wakadzikira zvakanyanya.
Kugona kwemuviri wemunhu kutora oxygen kwakaderedzwa: Izvi zvinogona kukonzerwa nezvirwere zvemapapu zvinotevera: Asthma, emphysema (kukuvadzwa kwemasaga emhepo mumapapu), bronchitis, mabayo, pneumothorax (kubuda kwemhepo pakati pemapapu nemadziro echipfuva), yakanyanya Respiratory Distress Syndrome (ARDS), pulmonary edema (nekuda kwekuzvimba kwemapapu kwakaunganidzwa), Pulmonary fibrosis (mavanga emapapu), interstitial lung disease (nhamba huru yezvirwere zvemapapu zvinowanzokonzera kuenderera mberi kwemapapu), zvirwere zvehutachiona, zvakadai. seCOVID-19
Mamwe mamiriro ezvinhu anosanganisira: anemia, apnea yekurara (kurara uchifema kwenguva pfupi), kuputa.
Kukwanisa kwemoyo kupa mweya weokisijeni kumapapu kunoderedzwa: chinonyanya kukonzera chirwere chemoyo chekuzvarwa (kuremara kwemoyo pakuzvarwa).
