Liphello tsa Pigmentation ea Letlalo ho Pulse Oximeter Accuracy at Low Saturation

PULSE oximetry ka khopolo-taba e ka kopanya arterial hemoglobin saturation ho tloha ho karo-karolelano ea pulsatile ho ea ho kakaretso ea khanya e khubelu e fetisoang e arotsoe ka karolelano e tšoanang bakeng sa khanya ea infrared transilluminating monoana, tsebe, kapa lisele tse ling.Saturation e nkiloeng e lokela ho ikemela ntle le 'mala oa letlalo, le mefuta e meng e mengata, joalo ka khatello ea hemoglobin, polisi ea manala, litšila le jaundice.Lithuto tse 'maloa tse kholo tse laoloang ha li bapisa bakuli ba batsho le ba basoeu (batho ba 380) 1,2 ha ba tlaleha liphoso tse kholo tse amanang le pigment ho pulse oximeters nakong ea ho tlala ho tloaelehileng.

 

Leha ho le joalo, Severinghaus le Kelleher3 ba ile ba hlahloba lintlha tse tsoang ho bafuputsi ba 'maloa ba neng ba tlalehile liphoso tsa anecdotal (+3 ho + 5%) ho bakuli ba batšo.le al.8 Cotele al.9 e tlalehile hore poleiti ea lipekere le enke holim'a letlalo li ka baka liphoso, se fumanoeng se tiisitsoe ka mokhoa o sa reroang ke ba bang ho tsoa ho enke ea menoana, 10 henna,11 le meconium.12 Lidae tse kentsoeng ka methapo li baka liphoso tsa nakoana.13 Leele al.14 e fumane overestimation ea saturation, haholo-holo ho saturation e tlase ho bakuli ba mebala (Indian, Malaykhahlano leSechaena).The Technology Subcommittee ea Sehlopha sa Ts'ebetso ea Tlhokomelo e Bohlokoa, Lekala la Bophelo bo Botle la Ontario, 15 e tlalehile liphoso tse sa amoheleheng ho pulse oximetry ka saturation e tlase litabeng tse nang le mebala.Zeballos le Weisman16 ba ile ba bapisa ho nepahala ha Hewlett-Packard (Sunnyvale, CA) ear oximeter le Biox II pulse oximeter (Ohmeda, Andover, MA) ho bahlankana ba batšo ba 33 ba ikoetlisang libakeng tse tharo tse fapaneng tse etsisitsoeng.Bophahamong ba 4,000 m, moo arterial saturation saturation (Sao2) e neng e tloha ho 75 ho isa ho 84%, Hewlett-Packard e ne e nyenyefatsa Sao2by 4.8 ± 1.6%, athe Biox e fetelletse Sao2by 9.8 ± 1.8% (n = 22).Ho ile ha boleloa hore liphoso tsena, tseo pele li ileng tsa tlalehoa ho ba basoeu, ka bobeli li ne li feteletsoa ho batho ba batšo.
Nakong ea lilemo tsa rona tse ngata tsa ho leka ho nepahala ha pulse oximeter ho phallo ea oksijene e tlase ho 50%, ka linako tse ling re hlokometse leeme le phahameng ka mokhoa o sa tloaelehang, haholo maemong a tlase haholo, ho tse ling empa eseng lithutong tse ling tse nang le 'mala o tebileng.Ka hona, lipatlisiso tsena li ne li etselitsoe ho fumana hore na liphoso tse tlase tsa Sao2correlate le 'mala oa letlalo.

 

Li-pulse oximeter tsohle tse rekisoang United States li hlokoa ke Tsamaiso ea Lijo le Lithethefatsi tsa US hore li lekoe le ho netefatsoa hore li nepahetse ho isa ho ± 3% ea metso e bolelang phoso ea lisekoere ho Sao2values ​​pakeng tsa 70 le 100%.Bongata ba liteko tsa calibration le netefatso li entsoe lithutong tsa baithaopi tse nang le letlalo le khanyang.

 

Tsamaiso ea Lijo le Lithethefatsi e sa tsoa fana ka maikutlo a hore liphuputso tsa ho nepahala ha pulse oximeter tse rometsoeng bakeng sa tumello ea sesebelisoa sa Tsamaiso ea Lijo le Lithethefatsi li kenyelletsa batho ba nang le mefuta e mengata ea mebala ea letlalo, leha ho se tlhokahalo ea palo e fanoeng.Ha re tsebe lintlha tse tšehetsang ketso ena.

 

Haeba ho na le leeme la bohlokoa le reproducible positive, tlaase saturation bafo ba letlalo le letšo-letšo, ho kenyelletsoa ha bafo ba letlalo le letšo-letšo ho tla eketsa sehlopha sa liteko se bolelang liphoso tsa lisekoere, mohlomong ho lekaneng ho baka ho hana ke Tsamaiso ea Lijo le Lithethefatsi.Haeba leeme le ka ikatisetsang le fumanoa maemong a tlase ho batho ba letlalo le letšo maemong ohle a pulse oximeter, lileibole tsa temoso li lokela ho fanoa ho basebelisi, mohlomong ka lintlha tse khothalelitsoeng tsa tokiso.
