Muva nje, i-oxygen ekheniwe idonsele ukunakwa kweminye imikhiqizo ethembisa ukuthuthukisa ezempilo namandla, ikakhulukazi eColorado. Ochwepheshe beCu Anschutz bachaza okwenziwa abakhiqizi.
Kungakapheli iminyaka emithathu, i-oksijini ekheniwe yayicishe itholakala njengomoya-mpilo wangempela. Ukwanda kwesibalo esiqhutshwa ngubhubhane lwe-covid-19, "ithangi le-shark" amadili kanye nezigcawu kusuka ku- "The Simpsons" kuholele ekuhlaselwenineni ngenani lamathini amancane we-aluminium kumakhefu ezitolo aqhamuka eziteshini zegesi.
Ukuqinisa umoya-mpilo kunama-90% emakethe ye-oxygen ethe xaxa, ngokuthengisa okwandayo ngokuqhubekayo ngemuva kokuwina okungokoqobo kwebhizinisi show "Shark Tank" ngo-2019.
Yize amalebula asho ukuthi imikhiqizo ayivunyelwe yi-Food and Drug Administration futhi isetshenziswa ekuzijabuliseni kuphela, izithembiso zokukhangisa zithuthukise impilo, ukusebenza kwezindiza ezithuthukisiwe kanye nosizo nge-Alture Acclimatization, phakathi kwezinye izinto.
Uchungechunge luhlola ukuthambekela kwezempilo kwamanje ngelensi yesayensi yochwepheshe beCU ANSCHUTZ.
UColorado, unomphakathi wayo omkhulu wokuzijabulisa ongaphandle kanye nezinkundla zokudlala eziphakeme, usephenduke imakethe eqondisiwe yamathangi we-oxygen ephathekayo. Kepha bakhulule?
"Zimbalwa izifundo ezihlolisisile izinzuzo zokungezelelwa kwe-oxygen yesikhathi esifushane," kusho uLindsay Forbes, MD, umfo ekuhlukaniseni umuthi we-Pulmonary kanye nokuqonda okubucayi e-University of Colorado School of Medici Medical. "Asinayo imininingwane eyanele," kusho uForbes, ozojoyina uMnyango ngoJulayi.
Lokhu kungenxa yokuthi i-oksijini kadokotela, elawulwa yi-FDA, iyadingeka ezilungiselelweni zezokwelapha isikhathi eside. Kunesizathu sokulethwa ngale ndlela.
"Lapho ukhipha umoya-mpilo, uhamba usuka ephethini lokuphefumula ungene egazini futhi utholwe yi-hemoglobin," kusho uBen Housigman, i-MD, uSolwazi Emeritus yemithi enesimo esiphuthumayo. IHemoglobin yabe isisabalalisa ama-molecule ka-oksijini kuwo wonke umzimba, inqubo ephumelelayo neqhubekayo.
Ngokusho kukaForbes, uma abantu benamaphaphu aphilile, imizimba yabo ingagcina amazinga ajwayelekile we-oxygen egazini labo. "Akunabufakazi obanele bokuthi bengeza ama-oksijini amaningi kumazinga ajwayelekile we-oksijini kusiza umzimba ngokomzimba."
Ngokusho kwe-Forbes, lapho abasebenzi bezempilo behlinzeka ngo-oksijini ngamazinga aphansi oxygen, imvamisa kuthatha imizuzu emibili kuya kwemithathu yokulethwa komoya-mpilo okuqhubekayo ukuze ubone ushintsho emazingeni asolwandle oluseziguli. "Ngakho-ke angilindele nje ukukhukhumala okukodwa noma okubili kusuka ku-canister ukuhlinzeka umoya-mpilo okwanele egazini eligeleza emaphashini ukuze kube nomphumela onenjongo."
Abakhiqizi abaningi be-oxygeners kanye nama-cylinders asebe-oksijini bangeza amafutha asemqoka amnandi afana ne-peppermint, owolintshi noma i-eucalyptus ku-oksijini. I-Pulmonmologists ngokuvamile incoma ukuthi akekho umuntu odonsa amafutha, akwazi ukufudumala kokuvuvukala kanye nokusabela komzimba. Kubantu abanezimo ezithile zamaphaphu, njenge-asthma noma isifo esingamahlalakhona ama-pulmonaryform, engeza uwoyela kungadala ama-flare-ups noma izimpawu.
Yize amathangi e-oksijini ngokuvamile awanebala kubantu abaphilile (bheka i-sidebar), i-Forbes noHonigman bancoma ukuthi akekho olisebenzisayo ukuze azinikele kunoma yisiphi isizathu sezokwelashwa. Bathi ukuthengisa okukhuphukayo ngesikhathi sobhubhane kusikisela ukuba abanye abantu bayisebenzisa ukuphatha i-Covid-19, okuhlukile okuyingozi okungabambezela ukwelashwa okubucayi.
Okunye ukucatshangelwa okubalulekile, kusho uHonigman, ukuthi umoya-mpilo uyadlula. "Lapho nje usuyikhipha, kuyanyamalala. Ayikho i-akhawunti ye-reservoir noma i-akhawunti yokonga i-oxygen emzimbeni. "
NgokukaHonigman, esifundweni esisodwa lapho amazinga we-O Oksijini ezifundweni ezinempilo alinganiswa kusetshenziswa ama-oximeters we-pulse, amazinga we-oksijini ahlala eziteshini eziphakeme ngemuva kwemizuzu emithathu ngemuva kokumiswa komoya-mpilo, i-oksijini yeleveli ibuyile. emazingeni okungezwa kwangaphambili cishe imizuzu emine.
Ngakho-ke abadlali be-basketball abangochwepheshe bangathola inzuzo ethile ekuqhubekeni nokuphefumula umoya-mpilo phakathi kwemidlalo, kusho uHonigman. Kukhulisa kafushane amazinga we-oksijini emisipha ye-hypoxic.
Kepha ama-skiers ahlala epompa igesi emathangini, noma aze aqonde ku "oksijini emadolobheni asezintabeni noma emadolobheni angcoliswe kakhulu ahlinzeka ngo-oksijini, evame ukuthuthukisa ukusebenza kwawo phakathi kwebanga lonke. usuku. Ukusebenza emithambekeni ye-ski. , ngoba umoya-mpilo uhlakazeke isikhathi eside ngaphambi kokwethulwa kokuqala.
I-Forbes futhi iphinde yaphinda ukubaluleka kohlelo lokulethwa kwezidingo, kuphawula ukuthi i-oxygen canisters ayifiki nemaskhi yezokwelapha emboza impumulo nomlomo. Ngakho-ke, isimangalo sokuthi "umphefum-mpilo omsulwa esingu-95%" futhi singamanga, kusho yena.
"Esimweni esibhedlela, sine-oklygen yezokwelapha futhi siyikhomba amazinga ahlukene ukunikeza abantu amanani ahlukahlukene omoya-mpilo ngokuya ngokuthi bakuthola kanjani. "Ukwenza isibonelo, nge-cannula yamakhala, empeleni kungenzeka ukuthi ngithole i-oksijini engu-95%. akutholakali. "
I-Forbes ithi umoya wekamelo, oqukethe ama-oksijini angama-21%, ahlangana nomoya-mpilo onqunyelwe ngoba i-A KORD AR ARO AR ARO AR AR AR AR AR AR AROR AR AR AR AR AR AR AR AR AR AIR AR AR AR AIR AR AR AIR AR AR AR AR AR AR AR AR AROR ART ARELS ASTICE Azungeze I-Cannula ye-NASAL, ehlisa izinga le-oxygen etholakele.
Amalebula amathangi we-oxygen amaCanched athi asiza ukuthi asiza izinkinga ezihlobene nokuhlobene: kwiwebhusayithi yayo, ukukhuphula umoya-mpilo empeleni kubala iColorado nama-Rockies njengezindawo zokuthwala umoya-mpilo onamakhemikhali.
Ukuphakama okuphezulu, okwehlise umfutho womoya, okusiza ukuthutha umoya-mpilo kusuka emkhathini uye emaphashini, kusho uHonigman. "Umzimba wakho awumukeli umoya-mpilo ngendlela ephumelelayo njengoba eqala olwandle."
Amazinga we-oksijini aphansi angadala ukugula ukuphakama, ikakhulukazi izivakashi eColorado. "Cishe bangamaphesenti angama-20 kuye kwangama-25 abantu abavela ezingeni lolwandle eziya ezinhlakeni eziphakeme bathola ukugula okunamandla kwentaba (AMS)," kusho uHonigmann. Ngaphambi kokuba athathe umhlalaphansi, wasebenza esikhungweni sokucwaninga okuphezulu e-University of Colorado Anschutz camputer, lapho eqhubeka nokwenza ucwaningo.
Ibhodlela le-7-litre lokukhuthaza i-oxygen libiza cishe ama- $ 10 futhi lingakwazi ukuhlinzeka ngokuhlala okungu-100 ku-95% umoya-mpilo omsulwa umzuzwana owodwa.
Ngenkathi izakhamizi zaseDenver zimelana kakhulu, cishe amaphesenti ayi-8 kuye kwayi-10 athola ama-AMS ngenkathi ehambela amadolobha asenyuka enyuka, kusho yena. Izimpawu ezibangelwa umoya-mpilo ophansi wegazi (amakhanda, isicanucanu, ukukhathala, ukulala kwenkinga) kuvame ukuvela kungakapheli amahora ayi-12 kuye kwangama-24 futhi kungashukumisela abantu ukuba bafune usizo ku-oxygen bar, kusho uHonigman.
"Empeleni kuyasiza ukunciphisa lezi zimpawu. Uzizwa ungcono lapho uphefumula umoya-mpilo, futhi isikhashana ngemuva kwalokho, "kusho uHonigman. "Ngakho-ke uma unezimpawu ezithambile bese uqala ukuzizwa ungcono, kungenzeka ukuthi unikeze umuzwa wenhlala-kahle."
Kepha kubantu abaningi, izimpawu ziyabuya, zishukumisela abanye ukuthi babuyele kubha ye-oxygen ukuze bathole impumuzo kangaka, kusho uHonigman. Kusukela ngaphezulu kwama-90% abantu abahlupha ama-altituse aphezulu kungakapheli amahora angama-24-48, lesi sinyathelo singase sibe namandla. Abanye ososayensi bakholelwa ukuthi umoya-mpilo owengeziwe uzobambezela lokhu kuvumelana ngokwemvelo kuphela, kusho yena.
"Umbono wami uqobo ukuthi kuwumphumela we-placebo, okungenakwenza lutho nge-physiology," avuma uHonigman.
"Ukuthola i-oksijini eyengeziwe kuzwakala kukuhle futhi kungokwemvelo, kepha angicabangi ukuthi isayensi isisekela," kusho yena. "Kunobufakazi bangempela obukhulu bokuthi uma ucabanga ukuthi okuthile kuzokusiza, empeleni kungakwenza uzizwe ungcono."
Egunyazwe yiKhomishini Yezemfundo Ephakeme. Zonke izimpawu zokuthengisa ziyimpahla ebhalisiwe yeNyuvesi. Isetshenziswe kuphela ngemvume.
