Umgaqo osebenzayo we-spo2 sensor
EyemveliSpO2indlela yokulinganisa kukuqokelela igazi emzimbeni, kunye nokusetyenziswa komhlalutyi wegesi yegazi kuhlalutyo lwe-electrochemical ukulinganisa inxenye yoxinzelelo lweoksijini yegazi PO2 ukubala ukugcwala kweoksijini yegazi.Nangona kunjalo, inzima kakhulu kwaye ayinakubekwa esweni ngokuqhubekayo.Ngoko ke, i-oximeter yavela.
I-oximeter iqulunqwe kakhulu yi-microprocessor, imemori (i-EPROM kunye ne-RAM), iziguquli ezimbini ze-digital-to-analog ezilawula ii-LEDs isixhobo .izihluzi kunye nokwandisa umqondiso ofunyenwe yi-photodiode, kwaye udibanise uphawu olufunyenweyo ukubonelela nge-analog-to microprocessor's. -umguquleli wedijithali uqulunqwe.
I-oximeter ithatha i-sensor ye-photoelectric sensor yomnwe womnwe.Udinga kuphela ukubeka inzwa emnweni xa ulinganisa.usebenzisa umnwe njengesitya esicacileyo se-hemoglobin, kwaye usebenzise ukukhanya okubomvu kunye ne-wavelength ye-660 nm kunye nokukhanya okukufutshane kwe-infrared kunye ne-wavelength ye-940 nm njengemitha.Ngenisa umthombo wokukhanya kwaye ulinganise ubunzulu bokuhanjiswa kokukhanya ngebhedi yethishu ukubala ugxininiso lwe-hemoglobin kunye nokugcwala kweoksijini yegazi.
Abantu abasebenzayo beoximeter
1. Abantu abanezifo ze-vascular (isifo senhliziyo, i-hypertension, i-hyperlipidemia, i-cerebral thrombosis, njl.)
Kukho i-lipid deposits kwi-lumen ye-vascular, kwaye igazi alikho kakuhle, eliya kubangela ubunzima ekuboneleleni kwe-oxygen.I-oximeter inokukhangela ngokulula i-oksijini yegazi lomzimba womntu.
2.Izigulane ze-Cardiovascular
Igazi le-Viscous, kunye nokuqina kwe-coronary arteries, linciphisa i-lumen ye-vascular, okukhokelela ekuboneleleni kwegazi okungahambi kakuhle kunye nobunzima bokubonelela nge-oxygen.Umzimba "yi-hypoxia" yonke imihla.I-hypoxia yexesha elide epholileyo, intliziyo, ingqondo kunye namanye amalungu asebenzisa i-oksijini ephezulu iya kuhla kancinci.Ke ngoko, ukusetyenziswa kwexesha elide kwe-pulse oximeter ukulinganisa umxholo we-oksijini yegazi kwintliziyo kunye nezigulane ze-cerebrovascular kunokuthintela ngokufanelekileyo ukwenzeka kwengozi.Ukuba i-hypoxia iyenzeka, isigqibo sokuncedisa i-oksijini senziwe ngokukhawuleza, esinokunciphisa ngokufanelekileyo ithuba lokuhlaselwa kwesifo.
3. Abantu abanezifo zokuphefumla (i-asthma, i-bronchitis, i-bronchitis engapheliyo, isifo sentliziyo ye-pulmonary, njl.
Uvavanyo lwe-oxygen yegazi kwizigulana zokuphefumla kubaluleke kakhulu.Kwelinye icala, ubunzima bokuphefumla bunokukhokelela ekufumaneni ioksijini ngokwaneleyo.Kwelinye icala, ukuzingisa kwe-asthma kunokuthintela amalungu amancinci, ukwenza ukutshintshiselana ngegesi kube nzima kwaye kukhokelela kwi-hypoxia.Ibangela amanqanaba ahlukeneyo omonakalo entliziyweni, emiphungeni, engqondweni nakwizintso.Ngoko ke, ukusetyenziswa kwe-pulse oximeter ukufumana umxholo we-oksijeni yegazi kunokunciphisa iziganeko zendlela yokuphefumula.
4.Abadala abangaphezu kweminyaka engama-60
Umzimba womntu uxhomekeke kwigazi ukuhambisa ioksijini.Ukuba kukho igazi elincinci, kuya kubakho ioksijini encinci ngokwendalo.Ngeoksijini encinci, imeko yomzimba iyehla ngokwendalo.Ngoko ke, abantu abadala kufuneka basebenzise i-pulse oximetry ukuvavanya umxholo we-oxygen egazini yonke imihla.Emva kokuba i-oxygen yegazi ingaphantsi kwinqanaba lesilumkiso, i-oxygen kufuneka yongezwe ngokukhawuleza.
Isihlwele se-5.Ezemidlalo kunye nokufaneleka
Umsebenzi wengqondo wexesha elide kunye nokuzilolonga okunzima kuxhomekeke kwi-hypoxia, echaphazela impilo ye-myocardial kunye nengqondo.Njengabathandi bezemidlalo;abasebenzi bengqondo;abathandi bohambo bethafa.
6.Abantu abasebenza iiyure ezingaphezu kwe-12 ngosuku olunye
Ukusetyenziswa kweoksijini kwengqondo kubalelwa kwi-20% yomzimba wonke ofumana ioksijini, kwaye ukusetyenziswa kweoksijini yengqondo kuya kwanda ngokuqinisekileyo kunye nokutshintsha komsebenzi wengqondo.Umzimba womntu unokuthatha ioksijini elinganiselweyo, utye ngakumbi, kwaye utye kancinci.Ukongeza kokubangela ukuba nesiyezi, ukudinwa, inkumbulo engalunganga, ukuphendula kancinci kunye nezinye iingxaki, kunokubangela umonakalo omkhulu kwingqondo kunye ne-myocardium, kunye nokufa ngenxa yokusebenza kakhulu.Ngoko ke, abantu abafunda okanye basebenze iiyure ze-12 ngosuku kufuneka basebenzise i-pulse oximetry ukuvavanya i-oxygen yegazi yonke imihla Umxholo, ukubeka iliso kwimpilo ye-oksijeni yegazi ngamaxesha athile, ukuqinisekisa impilo yentliziyo kunye nengqondo.
