Ungagada kanjani ukugcwala kwe-oxygen egazini?
Ikhala noma isiphongo kungathola ukugcwala komoyampilo womuntu egazini
Ikhala lingenalutho futhi lincane, okusiza ukukhomba umoya-mpilo wegaziIkhebula lesandiso senzwa ye-SpO2.Kodwa-ke, i-nasal saturation probe ibiza kakhulu futhi ingasetshenziswa njengophenyo olusizayo.
Isikhundla sesiphongo sinenzuzo kakhulu kunezinye izikhundla ngoba asithinteki kalula ngokuma kwe-receptor kanye nokunyakaza kwezitho, futhi kulula ukuyilungisa.Nokho, ngenxa yokuthi uphenyo lwasebunzini lubiza kakhulu, ngokuvamile lutuswa ezigulini ezidinga ukuvivinya umzimba.
Qaphela uma usebenzisa izintambo zokunweba izinzwa ze-spo2
1. Izinzipho zesiguli akufanele zibe zinde kakhulu futhi akufanele zibe namabala, ukungcola noma izinzipho.
2. Uma umunwe wesiguli uzizwa ungakhululekile ngemva kokuqapha umoya-mpilo wegazi isikhathi eside, kufanele kushintshwe omunye umunwe ukuze uqashwe.
3. Phakathi nenqubo yokuqapha, uma isiguli kanye nabasebenzi bezokwelapha beshayisana futhi badonsa i-spo2 probe nocingo, ukuphazamiseka kuzokwenzeka.Kutuswa ukuba isiguli sihlale sithule bese sifunda inani ngokunembe kakhudlwana.
Isigaba sokuthola ukugcwala kwesimo segazi komoyampilo
Indlela yendabuko ye-electrochemical yokulinganisa ukugcwala komoyampilo isebenzisa aalahlwayo Spo2 inzwaukuqoqa igazi kuqala emzimbeni womuntu (okuvame ukusetshenziswa kakhulu ukuqoqa igazi le-arterial), bese usebenzisa i-blood gas analyzer ukuze uhlaziye i-electrochemical, futhi ulinganise umoya-mpilo we-arterial phakathi nemizuzu embalwa Ukucindezela (PaO2).Bala ukugcwala komoyampilo we-arterial (SaO2).Ngenxa yokuthi le ndlela idinga ukubhoboza kwe-arterial noma intubation, izobangela ubuhlungu esigulini futhi ayikwazi ukuqapha ngokuqhubekayo.Ngakho-ke, kunzima ngesiguli ukuthola ukwelashwa esimweni esiyingozi.Inzuzo yendlela ye-electrochemical ukuthi umphumela wokulinganisa unembile futhi unokwethenjelwa, kodwa okubi ukuthi iyinkinga futhi ayikwazi ukugadwa ngokuqhubekayo.Kuyindlela yokulinganisa ukugcwala komoyampilo egazini.
Indlela yokubona iyindlela entsha yokulinganisa optical enqoba ukushiyeka kwendlela ye-electrochemical.Kuyindlela eqhubekayo yokulinganisa umoya we-oxygen egazini engasetshenziswa emakamelweni ezimo eziphuthumayo, emakamelweni okuhlinza, amagumbi okuthola usizo kanye nezifundo zokulala.Umgomo uwukuthola izinguquko ekumunceni kwegazi futhi ulinganise iphesenti le-oxyhemoglobin (HbO2) ku-hemoglobin (Hb).Thola i-SpO2.Inzuzo yale ndlela yukuthi ingakwazi ukulinganisa ngokuqhubekayo umzimba womuntu ngaphandle kokulimala, futhi ithuluzi lilula futhi lisebenziseka kalula, ngakho liye laheha ukunakwa okwengeziwe.Okubi ukuthi ukunemba kwesilinganiso kuphansi kunendlela ye-electrochemical, futhi iphutha elibangelwa inani eliphansi le-oxygen yegazi likhulu.Ama-oximeter endlebe, i-multi-wavelength oximetersfuthi kuvele ama-pulse oximeter asanda kwethulwa.Iphutha lokulinganisa le-pulse oximeter yakamuva lingalawulwa ngaphakathi kwe-1% ukuze kuhlangatshezwane nezidingo zokusetshenziswa komtholampilo.Nakuba zingagculisi kwezinye izici, izinzuzo zazo zomtholampilo ziye zaqashelwa kabanzi.
