Nkag siab SpO2 Sensor Test

Los ntawm Andrew Clay, Fluke Biomedical

Editor's Note: Kab lus no, sau nyob rau hauv 2015, tseem yog tus nyeem ntawv tshaj plaws24 × 7qhov chaw.Peb vam tias nws tuaj yeem muab cov ntaub ntawv koj xav tau thaum koj kuaj SpO2sensors.

Saib xyuas SpO2, qhov feem pua ​​​​saturation ntawm oxygen hauv cov ntshav, tau dhau los ua tus qauv ntawm kev saib xyuas neeg mob thoob plaws ntiaj teb.Yuav luag txhua tus neeg saib xyuas tus neeg mob muaj lub peev xwm ua tau los yog txuas tau los saib xyuas cov cim tseem ceeb no.SPO2yog ib txoj hauv kev tsis ncaj thiab tsis muaj kev cuam tshuam ntawm kev ntsuas oxygen saturation hauv cov ntshav.Nws yuav tsum tau soj ntsuam nrog rau tag nrho lwm yam physiological tsis thaum lub sij hawm kev tiv thaiv los yog kho kev kho ntawm tus neeg mob saib xyuas, los yog stand-alone ntaus ntawv.

Technology

SpO2yog ntsuas ntawm qhov periphery, feem ntau yog ntiv tes, thiab yog ib qho kev ntsuas ntawm kev noj qab haus huv ntawm cov hlab plawv thiab cov hlab ntsws.Lub pulse oximeter noninvasively ntsuas cov pa oxygen saturation ntawm tus neeg mob cov ntshav.Cov cuab yeej no muaj lub teeb liab thiab lub teeb infrared, lub teeb pom kev zoo, thiab kev sojntsuam kom xa lub teeb los ntawm lub txaj translucent, pulsating arterial txaj, feem ntau yog ntiv tes lossis pob ntseg.Oxygenated hemoglobin (O2Hb) thiab deoxygenated hemoglobin (HHb) nqus lub teeb liab thiab infrared txawv.Qhov feem pua ​​​​ntawm cov hemoglobin saturation hauv cov ntshav arterial tuaj yeem suav los ntawm kev ntsuas lub teeb pom kev hloov pauv uas tshwm sim los ntawm cov hlab ntsha hauv cov hlab ntshav.

Ntau yam tuaj yeem cuam tshuam qhov tseeb ntawm SPO2kev ntsuas, suav nrog cov tawv nqaij, xim, qhov txhab, caws pliav, tattoos, ntsia thawv polish, hypothermia, anemia, tshuaj noj, kev cuam tshuam lub teeb, thiab kev txav mus los.

SPO2yog ntsuas siv lub sensor, feem ntau txuas nrog tus neeg mob tus ntiv tes.Muaj ob txoj hauv kev ntawm SpO2technology: transmissive thiab reflective.Txoj kev transmissive yog qhov siv ntau dua ntawm ob.Raws li pom nyob rau hauv daim duab 1, transmissive technology xa liab thiab infrared teeb los ntawm tus ntiv tes mus rau ib tug yees duab ntes.

Daim duab 1: Transmissive technology, feem ntau siv daim ntawv kho mob pulse oximetry.Nyem rau kom loj.Lwm txoj kev siv rau SPO2cia siab rau kev siv tshuab reflective.Raws li pom nyob rau hauv daim duab 2, txoj kev no muaj lub transmitter thiab receiver nyob rau hauv tib lub dav hlau.Reflective SPO2sensors tuaj yeem muab tso rau ntawm lwm qhov chaw ntawm lub cev ntawm tus ntiv tes, xws li lub hauv pliaj.

Kev sim

Txhua lub tshuab pulse oximetry cov chaw tsim khoom yuav tsum txiav txim siab qhov tseeb ntawm lawv cov cuab yeej los ntawm kev sim tib neeg.Raws li Dennis J. McMahon piav nyob rau hauv nws daim ntawv dawb, "Tsis muaj ib yam dab tsi li SpO2Simulator, "1nyob rau hauv "kev tswj hwm kev ua kom tsis txaus ntseeg, cov neeg tuaj yeem pab dawb ua pa ib ntus ntawm cov roj sib xyaw ua ke ntawm cov ntsiab lus oxygen txo qis thaum txuas nrog tus qauv saib."Cov ntshav kuaj ntshav tom qab ntawd raug coj los ntawm cov neeg mob los ntsuas cov pa oxygen saturation hauv chav kuaj mob.

Qhov tshwm sim ntawm qhov kev sim no yog ib daim duab rau tus qauv ntawm SPO2sensor thiab saib.Daim duab no yog hu ua R-khoov.Raws li pom nyob rau hauv daim duab 3, ib qho R-nqaj piav qhia txog kev sib raug zoo ntawm qhov sib piv ntawm lub teeb liab thiab lub teeb infrared piv rau qhov pom oxygen saturation raws li sau thaum tib neeg kuaj.R-nqaj ces siv rau hauv lub firmware rau ib qho kev ntsuas thiab rau SPO2cov neeg kuaj.

Daim duab-3-SpO2-Sensor-Testing-300x248

Daim duab 3: Ib qho piv txwv ntawm R-kov, sib cuam tshuam O2 saturation nrog tus nqi R.Nyem rau kom nthuav davSimulators, calibrators, thiab functional testers rau pulse oximeters tau txhais nyob rau hauv ISO tus qauv 80601-2-61.Tsis zoo li lwm yam khoom siv kho mob, pulse oximeters tsis yog tsim los rau calibrated sab nraum lub Hoobkas.Tsis muaj txoj hauv kev lees paub los txheeb xyuas qhov tseeb calibration ntawm pulse oximeter uas tsis yog kev sim tib neeg.Feem ntau SpO2kuaj cov cuab yeej ntawm kev ua lag luam yog nyob rau hauv kev ua haujlwm tester qeb.

Raws li Tobey Clarke hauv nws phau ntawvCov Khoom Siv Kho Mob Zoo Assurance, tus neeg mob saib xyuas yuav tsum tau kuaj ua haujlwm tsawg kawg ib xyoos ib zaug.2Feem ntau cov neeg ua haujlwm kuaj xyuas SPO2sensor optically.Qhov no tso cai rau kev ntsuam xyuas ntawm lub sensor, cable, thiab saib xyuas.Qee cov neeg ua haujlwm ua haujlwm tau nkag mus rau lub teeb liab ncaj qha rau lub monitor, tsuas yog kuaj lub monitor.Lwm tus tuaj yeem kuaj lub cable kom txuas ntxiv mus.Feem ntau cov neeg ua haujlwm ua haujlwm tsuas yog kuaj cov thev naus laus zis, tsis muaj kev cuam tshuam.

Ib qho kev ua haujlwm zoo rau kev kuaj tus neeg mob saib xyuas lossis ib leeg SPO2saib xyuas suav nrog kev tshuaj xyuas lub cev, ua cov kev ntsuam xyuas hluav taws xob kev nyab xeeb, ua txhua qhov chaw tsim khoom pom zoo tiv thaiv kev saib xyuas, ua kev ntsuas kev ua tau zoo (nrog rau lub tswb thiab lwm yam kev ntsuas tshwj xeeb), thiab, thaum kawg, sau cov txiaj ntsig kev sim.
