Isimiso sokusebenza senzwa ye-spo2
OwendabukoI-SpO2indlela yokulinganisa iwukuqoqa igazi emzimbeni, nokusebenzisa isihlaziyi segesi yegazi ukuze kuhlaziywe i-electrochemical ukukala umfutho wengxenye womoya-mpilo wegazi PO2 ukubala ukugcwala komoyampilo egazini.Nokho, inzima kakhulu futhi ayikwazi ukugadwa ngokuqhubekayo.Ngakho-ke, i-oximeter yaba khona.
I-oximeter yakhiwe ngokuyinhloko i-microprocessor, inkumbulo (EPROM ne-RAM), iziguquli ezimbili zedijithali-kuya-analog ezilawula ama-LED kudivayisi .izihlungi futhi zikhulise isignali etholwe yi-photodiode, futhi ifake isiginali eyamukelwe ukuze inikeze i-analog-to ye-microprocessor. -digital converter yakhiwa.
I-oximeter isebenzisa inzwa yesithombe kagesi yomkhono womunwe.Udinga kuphela ukubeka inzwa emunweni lapho ukala.usebenzisa umunwe njengesiqukathi esikhanyelayo se-hemoglobin, futhi usebenzise ukukhanya okubomvu okunobude begagasi obungu-660 nm nokukhanya okuseduze kwe-infrared okunobude begagasi obungu-940 nm njengomsebe.Faka umthombo wokukhanya futhi ulinganise amandla okudluliswa kokukhanya ngombhede wethishu ukuze ubale ukugcwala kwe-hemoglobin nokugcwala komoyampilo egazini.
Abantu abasebenzayo bei-oximeter
1. Abantu abanezifo zemithambo yegazi (isifo senhliziyo, umfutho wegazi ophakeme, i-hyperlipidemia, i-cerebral thrombosis, njll.)
Kukhona ama-lipid deposits ku-lumen ye-vascular, futhi igazi alibushelelezi, okuzobangela ubunzima ekunikezeni umoya-mpilo.I-oximeter ingahlola kalula i-oxygen yegazi lomzimba womuntu.
2.Iziguli zenhliziyo
Igazi le-viscous, elihambisana nokuqina kwemithambo yenhliziyo, linciphisa i-lumen yemithambo, okuholela ekungatholakali kahle kwegazi kanye nokutholakala komoyampilo okunzima.Umzimba "uyi-hypoxia" nsuku zonke.I-hypoxia yesikhathi eside emnene, inhliziyo, ubuchopho nezinye izitho ezisebenzisa umoya-mpilo ophezulu zizokwehla kancane kancane.Ngakho-ke, ukusetshenziswa kwesikhathi eside kwe-pulse oximeter ukukala okuqukethwe komoyampilo wegazi ezigulini zenhliziyo nemithambo ye-cerebrovascular kungavimbela ngempumelelo ukuvela kwengozi.Uma kwenzeka i-hypoxia, isinqumo sokwengeza umoya-mpilo senziwa ngokushesha, esinganciphisa ngempumelelo ithuba lokuhlaselwa yisifo.
3. Abantu abanezifo zokuphefumula (isifuba somoya, i-bronchitis, i-bronchitis engapheli, isifo senhliziyo yamaphaphu, njll.)
Ukuhlolwa komoyampilo wegazi ezigulini zokuphefumula kubaluleke kakhulu.Ngakolunye uhlangothi, ubunzima bokuphefumula bungabangela ukungeniswa kwe-oxygen okwanele.Ngakolunye uhlangothi, ukuphikelela kwesifuba somoya kungase futhi kuvimbele izitho ezincane, kwenze ukushintshana kwegesi kube nzima futhi kuholele ku-hypoxia.Idala amazinga ahlukene okulimala enhliziyweni, amaphaphu, ubuchopho ngisho nezinso.Ngakho-ke, ukusetshenziswa kwe-pulse oximeter ukuthola okuqukethwe kwe-oksijini egazini kunganciphisa ukwenzeka kwendlela yokuphefumula.
4.Abadala abangaphezu kweminyaka engama-60
Umzimba womuntu uthembele egazini ukuze udlulise umoya-mpilo.Uma kunegazi elincane, ngokwemvelo kuzoba ne-oxygen encane.Ngomoya-mpilo omncane, isimo somzimba siyehla ngokwemvelo.Ngakho-ke, asebekhulile kufanele basebenzise i-pulse oximetry ukuhlola okuqukethwe komoyampilo egazini nsuku zonke.Uma umoya-mpilo wegazi usungaphansi kwezinga lokuxwayisa, umoya-mpilo kufanele wengezwe ngokushesha ngangokunokwenzeka.
5.Isixuku sezemidlalo nokufaneleka
Umsebenzi wengqondo wesikhathi eside nokuzivocavoca kanzima kuthambekele ku-hypoxia, ethinta impilo ye-myocardial nengqondo.Njengabathanda ezemidlalo;abasebenzi bengqondo;abathandi bokuvakasha bethafa.
6.Abantu abasebenza amahora angaphezu kwayi-12 ngosuku
Ukusetshenziswa komoya-mpilo ebuchosheni kubala u-20% wawo wonke umzimba wokuthola umoya-mpilo, futhi ukusetshenziswa komoya-mpilo kobuchopho kuzokhula nakanjani ngokushintsha komsebenzi wengqondo.Umzimba womuntu ungadonsa umoya-mpilo olinganiselwe, udle kakhulu, futhi udle kancane.Ngaphezu kokubangela isiyezi, ukukhathala, inkumbulo engeyinhle, ukuphendula kancane nezinye izinkinga, kungase kubangele nomonakalo omkhulu ebuchosheni nase-myocardium, ngisho nokufa ngenxa yokusebenza ngokweqile.Ngakho-ke, abantu abafunda noma abasebenza amahora angu-12 ngosuku kufanele basebenzise i-pulse oximetry ukuhlola umoya wegazi nsuku zonke Okuqukethwe, ukuqapha impilo ye-oksijeni yegazi ngezikhathi ezithile, ukuze kuqinisekiswe impilo yenhliziyo nengqondo.
