I-Pulse oximetry ilungele ikakhulukazi ukulinganisa okungavamisile okuqhubekayo kokugcwala komoyampilo egazini.Ngokuphambene, amaleveli egesi yegazi uma kungenjalo anqunywe elabhorethri ngesampula yegazi elikhishiwe.I-Pulse oximetry iwusizo kunoma isiphi isimo lapho i-oxygenation yesiguli ingazinzile, okuhlanganisa ukunakekelwa okujulile, ukusebenza, ukutakula, izimo eziphuthumayo kanye nezilungiselelo zesigceme sasesibhedlela, abashayeli bezindiza ezingacindezelwanga, ukuze kuhlolwe ukuthi isiphi isiguli sithatha umoya-mpilo, kanye nokunquma ukusebenza kahle noma isidingo somoya-mpilo owengeziwe. .Nakuba i-pulse oximeter isetshenziselwa ukuqapha ukuhamba kwe-oxygen, ayikwazi ukunquma ukuguqulwa kwe-oksijeni, noma inani le-oxygen elisetshenziswa isiguli.Ngale njongo, kuyadingeka futhi ukukala amazinga e-carbon dioxide (CO2).Kungenzeka ukuthi ingasetshenziswa futhi ukuthola ukungahambi kahle ekungeneni komoya.Kodwa-ke, ukusetshenziswa kwe-oximeter ye-pulse ukuze kutholwe i-hypoventilation kuphazamiseka ngokusetshenziswa kwe-oksijeni eyengeziwe, njengoba kuphela lapho iziguli ziphefumula umoya wegumbi lapho okungavamile ekusebenzeni kokuphefumula kungabonakala ngokuthembekile ngokusetshenziswa kwayo.Ngakho-ke, ukuphathwa okujwayelekile kwe-oksijeni eyengeziwe kungase kungadingeki uma isiguli sikwazi ukugcina umoya-mpilo owanele emoyeni wekamelo, ngoba kungabangela i-hypoventilation ingabonakali.
Ngenxa yokuthi kulula ukuyisebenzisa kanye nekhono lokuhlinzeka ngamavelu e-oxygen saturation aqhubekayo futhi asheshayo, ama-pulse oximeters abaluleke kakhulu emithini yezimo eziphuthumayo futhi awusizo kakhulu ezigulini ezinezinkinga zokuphefumula noma zenhliziyo, ikakhulukazi i-COPD, noma ukuxilongwa kwezinkinga ezithile zokulala. njenge-apnea kanye ne-hyopnea.Ezigulini ezine-obstructive sleep apnea, ukufundwa kwe-pulse oximetry kuzoba ku-70% 90% ububanzi isikhathi esiningi esichithwa sizama ukulala.
Ama-pulse oximeter aphathwayo asebenza ngebhethri awusizo kubashayeli bezindiza abasebenza endizeni engacindezelwe ngaphezu kwamamitha angu-10,000 (3,000 m) noma amafidi angu-12 ,500 (3 ,800 m) e-US lapho kudingeka khona umoya-mpilo owengeziwe.Ama-portable pulse oximeters nawo awusizo kubaqwali bezintaba nakubasubathi amazinga omoya-mpilo wabo angase ehle ezindaweni eziphakeme noma ngokuzivocavoca.Amanye ama-pulse oximeters aphathwayo asebenzisa i-sofware echaza umoya-mpilo wegazi lesiguli kanye neshayela, esebenza njengesikhumbuzo sokuhlola amazinga komoyampilo wegazi.
Ukuthuthuka kokuxhumana kwenze kwaba nokwenzeka ngeziguli ukuthi zigadwe ngokuqhubekayo ukugcwala kwazo komoyampilo egazini ngaphandle kokuxhumeka ngekhebula kusiqapha sasesibhedlela, ngaphandle kokudela ukugeleza kwedatha yesiguli ebuyela kubaqaphi abaseceleni kombhede namasistimu okuqapha esiguli amaphakathi.
Ezigulini ezine-COVID-19, i-pulse oximetry isiza ekutholakaleni kusenesikhathi kwe-hypoxia ethule, lapho iziguli zisabukeka futhi zizwa zikhululekile, kodwa i-SpO2 yazo iphansi ngokuyingozi.Lokhu kwenzeka ezigulini kungaba esibhedlela noma ekhaya.I-Low SpO2 ingase ibonise inyumoniya enzima ehlobene ne-COVID-19, edinga umshini wokuphefumula.
