Njengoba i-coronavirus iqhubeka nokusabalala, kukhulunywa ngomshini omncane wezokwelapha amandla bakwazi ukuxwayisa iziguli ukuthi zifune usizo ngokushesha. Ukukhumbuza i-dressspin ngokuma nosayizi, i-oximeter yokushaya ishayela ngomunwe bese kuthi, ngemizuzwana, ulinganise isilinganiso senhliziyo yakho nezinga le-oxygen yegazi, elingathinteka zombili ezigulini ze-COVID-19.

Uma lokhu kuzwakala kungaziwa kahle, kungenxa yokuthi kungenzeka ukuthi uke wazibonela mathupha le divayisi ehhovisi likadokotela noma, ubuncane obungenalutho, usibonile esiqeshini EzamaGrey.

Ngaphandle kokuduma kwawo okusha, ama-pulse oximeters awayona ingxenye (okungenani okwamanje) yezinkombandlela ezisemthethweni zokuvimbela nokwelashwa kwe-COVID-19 ezisungulwe izinhlangano ezinkulu zezempilo. Noma kunjalo, abanye odokotela bakholelwa ukuthi igajethi encane ingaba ngumdlali obalulekile phakathi kwalolu bhubhane, isiza abantu, ikakhulukazi labo abangenakuqedwa amandla futhi abanezimo zamaphaphu ezikhona (ngenxa yobungozi babo bokuthola igciwane), ukuqapha amazinga abo ngaphandle kokushiya indlu yabo (ngemuva kwakho konke, izifundazwe eziningi zisakugcizelela ukubaluleka kokuhlala ekhaya). Khumbula: i-coronavirus ingadala umonakalo emaphashini akho, okuholela ekuphelelweni umoya futhi yehlise izinga le-oxygen egazini.

Nakhu okudingeka ukwazi.

Yini i-oximeter ye-pulse futhi isebenza kanjani?

I-pulse oximeter (a.k.a. pulse ox) iyisisetshenziswa sikagesi esikala izinga lokushaya kwenhliziyo yakho kanye nokugcwala noma inani le-oksijini emangqamuzaneni akho abomvu egazi, ngokusho kwe-American Lung Association (ALA). Nakuba ngobuchwepheshe ingaxhunywa kwezinye izingxenye zomzimba wakho (okungukuthi, ikhala, izindlebe, izinzwane), i-pulse oximeter ivamise ukubekwa komunye weminwe yakho. Idivayisi encane ibambelela kancane emunweni wakho futhi ilinganise izinga le-oksijeni yegazi lakho ngokukhanyisa ukukhanya kutho lwakho lomunwe. Iqondise ku-hemoglobin, iphrotheni emangqamuzaneni abomvu egazi athwala umoya-mpilo usuka emaphashini akho uwuyise kuwo wonke umzimba wakho. Kuye ngokuthi iphethe umoya-mpilo ongakanani, i-hemoglobin idonsa amanani ahlukene namaza okukhanya okukhanya. Ngakho-ke, inani lokukhanya okumunceke ngegazi lakho likhombisa izinga lakho le-oxygen egazini, ngokusho kweWorld Health Organisation (WHO).

Nakuba ucwaningo oluthile luye lwathola ukuthi ukunemba kwalokhu kufundwa kungahluka kuye ngomunwe osetshenzisiwe, ochwepheshe abaningi bezokwelapha bafaka i-pulse oximeter emunweni wokukhomba wesiguli. Ufuna ukugwema upholishi wezipikili omnyama nezinzipho ezinde noma ezingamanga, ngoba lezi zinto — kanye nezandla ezibandayo — zingathinta ukunemba kwemiphumela, kusho u-Osita Onugha, MD, umphathi wezokuhlinzwa kwezirobhothi kanye nomqondisi weLiving Innovation Lab e-John Wayne Cancer Institute e-Providence Saint John's Health Centre eSanta Monica, eCalifornia.

Ngakho-ke kufanele ufunde kanjani ukushaya kwe-oximeter yakho, ngokufanele? Ukugcwaliswa kwe-oxygen yakho egazini kufanele kube phakathi kwamaphesenti angama-95-100, ngokusho kwe-WHO. Iningi labantu abanempilo, nokho, lizothola ukufundwa phakathi kwamaphesenti angama-95-98, kusho uDkt. Onugha. Futhi uma ukufunda kwakho kwehla ngaphansi kwamaphesenti angama-93, kufanele ushayele udokotela wakho, ikakhulukazi uma izinga lakho beliphakeme esikhathini esidlule, kunezela uDavid Cennimo, M.D., umsizi kaprofesa wezokwelapha e-Rutgers New Jersey Medical School. Lokhu kungasho ukuthi ungahle ube ne-hypoxic, lapho umzimba wakho uncishwa khona umoya-mpilo, ngokusho kwe-WHO. Kodwa-ke, ukwehluka kwephesenti elilodwa kuya kwamabili kusuka ekufundeni kuya ekufundeni kuyinto evamile, kunezela uDkt Cennimo.

"Ngandlela thile, lokhu kufana nokuba ne-thermometer," usho kanje. "[I-oximeter ye-pulse] ingaba wusizo, kepha ngiyethemba ukuthi ngeke yenze umuntu asangane ukucabanga ngamanani amaningi. Ngakolunye uhlangothi, uma othile ezizwa ephelelwa umoya noma enezinye izimpawu zokuphefumula ezibakhathazayo, kufanele bafune bayakhathalela noma ngabe inkabi yabo ye-pulse 'ijwayelekile.'"

Futhi, ngesikhathi sobhadane lwe-coronavirus, yilezi zinkinga zokuphefumula ezinabantu abaqaphile kakhulu nganoma yiluphi ushintsho ekusebenzeni kwamaphaphu noma kwezempilo njengamanje.

Ungakwazi yini ukusebenzisa i-pulse ox ukuthola i-coronavirus?

Hhayi impela.

I-COVID-19 ingabangela ukusabela kokuvuvukala emaphashini, izinkinga zamaphaphu njengenyumoniya, kanye/noma amahlule egazi amancane amancane emaphashini. (Yikuphi, i-btw, kungesinye sezizathu esenza ukuthi ukufutheka kukholwe ukuthi kukhulisa ingozi yakho ye-coronavirus.) Lapho umuntu eba nesifo samaphaphu noma inkinga yamaphaphu, umzimba wakhe ungaba nenkinga yokudlulisa umoya-mpilo usuka kuma-alveoli (amasaka amancane amaphaphu ukuphela kwamashubhu akho e-bronchial) kumaseli awo egazi, kusho uDkt Cennimo. Futhi yilokhu odokotela abakutholayo ezigulini ze-COVID-19, uyanezela. (Psst... ezinye iziguli ze-coronavirus zingase zibe nokuqubuka.)

Odokotela futhi bayaqaphela umkhuba okhathazayo owaziwa ngokuthi "i-hypoxia ethule" phakathi kweziguli ze-coronavirus, lapho amazinga e-oxygen saturation abo ehla kakhulu, kepha awanawo umoya wokuphefumula, kusho uDkt Cennimo. “Ngakho-ke, kube neziphakamiso zokuthi ukuqapha okwengeziwe kungakhomba ukwehla kokugcwala komoya-mpilo—futhi kubangele ukunikeza umoya-mpilo—ngokushesha,” uyachaza.

Okwamanje, kunengxabano yokuthi ukuqapha njalo nge-oximeter ye-pulse kungasiza ekuhloleni abasebenzi ababalulekile ukukhombisa ukuthi balitholile yini igciwane futhi badinga ukuzihlukanisa.Kodwa uDkt. Onugha akaqiniseki ukuthi kuzoba usizo. "Nge-COVID-19, maningi amathuba okuthi uveze umkhuhlane kuqala, bese kuba ukukhwehlela, bese kuba nzima ukuphefumula, uma kufika kulelo qophelo. Izinga eliphansi lokugcwala komoyampilo mancane amathuba okuba kube uphawu lwakho lokuqala," esho. (Okuhlobene: Izimpawu Ezivame Kakhulu ZeCoronavirus Okufanele Uzifune, Ngokusho Kwezazi)

Ngakho-ke, ingabe kufanele uthenge i-oximeter ye-pulse?

Umbono uthi njalo futhi ngokufanele ukusebenzisa i-oximeter yokushaya ngamandla kungavumela iziguli ezine-COVID-19 nangaphandle kwayo ukugcina ithrekhi yamazinga azo okugcwaliswa komoya-mpilo. Kepha ngaphambi kokuthi uphume ukuyothenga eyodwa, yazi ukuthi odokotela bahlukene phakathi ngokuthi ngabe bayisidingo esiwumqedazwe noma cha (njengokuthi, buso bamaski obuso).

"Ngicabanga ukuthi kuwumqondo omuhle ezigulini ezine-COVID-19 ezihlala zodwa ekhaya, inqobo nje uma zazi ukuthi zenzeni ngolwazi - yiliphi izinga le-oxygen eliphansi kakhulu, nokuthi yini okufanele yenze uma lokho kwenzeka," kusho uRichard. Watkins, MD, udokotela wezifo ezithathelwanayo e-Akron, e-Ohio, kanye noprofesa ohlangene wezokwelapha zangaphakathi eNortheast Ohio Medical University. (Ungethuki futhi ushayele udokotela wakho.)

Ubuye acabange ukuthi inkabi ye-pulse ingaba wusizo kubantu abasolwa ngecala (funda: aliqinisekisiwe) le-COVID-19: "Bengizibuza ngabantu abashonele ekhaya - ikakhulukazi abantu abasha - uma ngabe ukuba ne-pulse oximeter kungenzeka ubazise noma nomndeni wabo ukuthi basenkingeni. " (Okuhlobene: Okufanele Ukwenze Kahle Uma Uhlala Nomuntu OneCoronavirus)

Kepha akuwona wonke umuntu ocabanga ukuthi kunesidingo. UDkt. Onugha noDkt. Cennimo bobabili bayavuma ukuthi kungenzeka ukuthi le divayisi ayidingeki umphakathi jikelele. "Uma unesifo esivele sikhona ngaphambili njengesifuba somoya noma i-COPD, kungase kube usizo kuwe ukwazi ukuthi ayini amazinga akho okugcwala komoyampilo," kunezela uDkt. Onugha. "Futhi, uma kutholakala ukuthi une-COVID-19, kungasiza [ukuqapha isimo sakho], kodwa, ngokuvamile, angicabangi ukuthi kusiza wonke umuntu."

Futhi, okwamanje azikho izincomo ezisemthethweni ezivela ezinhlanganweni ezinkulu zezokwelapha ezinjengeCenters for Disease Control and Prevention (CDC), i-WHO, ne-American Medical Association (AMA) mayelana nokusebenzisa i-oximeter yokushaya ngamandla uma kukhulunywa nge-COVID-19. Ngaphezu kwalokho, i-ALA isanda kukhipha umbiko kwabezindaba, ixwayisa ngokuthi i-pulse oximeter "ayiyona indawo yokukhuluma nomhlinzeki wezempilo" nokuthi "abantu abaningi abadingi ukuba ne-pulse oximeter ekhaya labo." (Okuhlobene: Okufanele Ukwenze Uma Ucabanga Ukuthi Unayo I-Coronavirus)

Noma kunjalo, uma wena yenza bafuna ukuyithenga ngezizathu ezihlobene ne-coronavirus noma ngenye indlela-iyathengeka futhi lezi zinguqulo zasekhaya ziyafinyeleleka-noma iyiphi i-pulse oximeter ongayithola esitolo semithi sendawo noma ku-inthanethi kufanele kwanele, kusho uDkt. Onugha. "Zonke zinembile, ingxenye enkulu," usho kanje. Zama i-ChoiceMMEd Pulse Oximeter (Ithenge, $ 35, target.com) noma i-NuvoMed Pulse Oximeter (Ithenge, $ 60, cvs.com). Qaphela ukuthi ama-pulse oximeters amaningi asedayiswe aphela, ngakho-ke kungase kuthathe ukusesha okuncane ukuze uthole igajethi etholakalayo. (Uma ufuna ukucophelela ngokuphelele, ungabheka i-Premarket Notification Database ye-Food and Drug Administration bese usesha i- "oximeter" ukuthola uhlu lwamadivayisi abonwa yi-FDA.)

Imininingwane ekule ndaba inembile njengesikhathi sokushicilela. Njengoba izibuyekezo mayelana ne-coronavirus COVID-19 ziqhubeka nokuvela, kungenzeka ukuthi ulwazi oluthile nezincomo kule ndaba kushintshile kusukela ekushicilelweni kokuqala. Sikukhuthaza ukuthi uhlole njalo izinsiza ezifana ne-CDC, i-WHO, kanye nomnyango wezempilo womphakathi wendawo ukuze uthole imininingwane yakamuva nezincomo.
