Munguva pfupi yapfuura, okisijeni yakachengetwa mumagaba yakakwezva kutariswa kwezvimwe zvigadzirwa zvinovimbisa kuvandudza hutano nesimba, kunyanya muColorado. Nyanzvi dzeCU Anschutz dzinotsanangura zviri kutaurwa nevagadziri.
Mukati memakore matatu, okisijeni yakakangwa yakanga yava kutowanikwa seokisijeni chaiyo. Kuwedzera kwekuda kwezvinhu nekuda kwedenda reCOVID-19, zvibvumirano zve "Shark Tank" uye zviitiko kubva ku "The Simpsons" zvakaita kuti huwandu hwemagaba madiki earuminiyamu awedzere pamasherufu ezvitoro kubva kumishonga kuenda kumagaraji epeturu.
Boost Oxygen ine musika weokisijeni unodarika 90%, uye kutengesa kuri kuramba kuchikwira mushure mekukunda chirongwa chebhizinesi che "Shark Tank" muna 2019.
Kunyangwe zvinyorwa zvichiti zvigadzirwa izvi hazvina kutenderwa neFood and Drug Administration uye ndezvekushandisa zvekuzvivaraidza chete, kushambadza uku kunovimbisa hutano huri nani, kuvandudzwa kwemitambo uye rubatsiro rwekujairana nenzvimbo dzakakwirira, pakati pezvimwe zvinhu.
Nyaya iyi inoongorora mafambiro ehutano aripo iye zvino kuburikidza nemaonero esainzi enyanzvi dzeCU Anschutz.
Colorado, ine nzvimbo yayo huru yekutandarira panze nenzvimbo dzekutambira vanhu dziri munzvimbo dzakakwirira, yave nzvimbo inonyanya kutengeswa matangi eoxygen anotakurika. Asi yakakwanisa here kuita izvi?
“Zvidzidzo zvishoma zvakaongorora mabhenefiti ekuwedzera okisijeni kwenguva pfupi,” akadaro Lindsay Forbes, MD, mumwe wevadzidzi muDivision of Pulmonary and Critical Care Medicine paYunivhesiti yeColorado School of Medicine. “Hatina ruzivo rwakakwana,” akadaro Forbes, uyo achabatana nedhipatimendi iri muna Chikunguru.
Izvi zvinodaro nekuti okisijeni inopihwa nechiremba, inodzorwa neFDA, inodiwa munzvimbo dzekurapa kwenguva yakareba. Pane chikonzero nei ichiendeswa nenzira iyi.
“Kana uchifema okisijeni, inofamba ichibva mutsinga yekufema ichipinda muropa uye inotorwa nehemoglobin,” akadaro Ben Honigman, MD, purofesa wezvekurapa kwekukurumidzira. Hemoglobin inobva yaparadzira mamorekuru aya eokisijeni mumuviri wese, nzira inoshanda uye inoenderera mberi.
Sekureva kweForbes, kana vanhu vaine mapapu ane hutano, miviri yavo inogona kuchengetedza mwero weokisijeni muropa ravo. "Hapana humbowo hwakakwana hunoratidza kuti kuwedzera okisijeni yakawanda pamwero weokisijeni wakajairika kunobatsira muviri."
Sekureva kweForbes, kana vashandi vehutano vachipa okisijeni kuvarwere vane mwero wakaderera weokisijeni, zvinowanzotora maminetsi maviri kusvika matatu ekupa okisijeni nguva dzose kuti pave nekuchinja kwemwero weokisijeni yemurwere. "Saka handingatarisiri kufemera kamwe chete kana kaviri kubva mugaba kuti kupe okisijeni yakakwana kuropa rinoyerera nemumapapu kuti rive nemhedzisiro ine zvarinoreva."
Vagadziri vazhinji vema "oxygen bars" nema "oxygen cylinders" vanowedzera mafuta anonhuhwirira akadai se "peppermint", "orange" kana "eucalyptus" mu "oxygen". Nyanzvi dzemapapu dzinowanzo kurudzira kuti pasave nemunhu anofema mafuta aya, vachiti anogona kuzvimba uye allergy. Kune vanhu vane mamwe mamiriro emapapu, akadai se "asthma" kana chirwere chemapapu chisingaperi, kuwedzera mafuta kunogona kukonzera kuputika kana zviratidzo.
Kunyangwe matangi eokisijeni asingawanzokuvadza vanhu vane hutano (ona parutivi), Forbes naHonigman vanokurudzira kuti pasave nemunhu anoashandisa kuzvirapa nechikonzero chipi zvacho chekurapa. Vanoti kukwira kwekutengesa panguva yedenda kunoratidza kuti vamwe vanhu vari kuashandisa kurapa COVID-19, rudzi rune njodzi runogona kunonotsa kurapwa kwakakosha.
Chimwe chinhu chakakosha kufunga nezvacho, Honigman akadaro, ndechekuti okisijeni inongopera. "Paunongoibvisa, inonyangarika. Hapana nzvimbo inochengeterwa okisijeni mumuviri."
Sekureva kwaHonigman, mune imwe ongororo umo mwero weokisijeni muvanhu vane hutano hwakayerwa uchishandisa pulse oximeters, mwero weokisijeni wevanhu vakayerwa wakadzikama zvishoma mushure memaminitsi matatu apo vanhu vakaramba vachigamuchira okisijeni, uye mushure mekunge okisijeni yamiswa, mwero weokisijeni unodzokera kumazinga asati awedzerwa kwemaminitsi mana.
Saka vatambi vebasketball vane hunyanzvi vanogona kuwana rubatsiro kubva mukuramba vachifema mweya pakati pemitambo, Honigman akadaro. Izvi zvinowedzera kwenguva pfupi mwero wemweya mutsandanyama dzine hypoxia.
Asi vanoskiya vanogaropomba gasi kubva mumatangi, kana kutoenda ku "oxygen bars" (nzvimbo dzinozivikanwa mumaguta emakomo kana maguta akasvibiswa zvakanyanya anopa okisijeni, kazhinji kuburikidza ne cannula, kwemaminitsi gumi kusvika makumi matatu panguva), havazovandudze mashandiro avo mukati menguva yese. Kushanda pa ski slopes. , sezvo okisijeni ichinyangarika kare kare mutambo usati watanga.
Forbes akadzokororawo kukosha kwenzira yekuendesa chikafu, achiti gaba reokisijeni hariuye nemasiki ekurapa anovhara mhino nemuromo. Saka, kutaura kuti gaba iri "95% oxygen yakachena" inhemawo, akadaro.
"Muchipatara, tine okisijeni yemhando yepamusoro uye tinoiisa padanho rakasiyana kuti vanhu vawane okisijeni yakasiyana zvichienderana nekuti vanoiwana sei. "Semuenzaniso, kana paine cannula yemhino, mumwe munhu anogona kunge ari kugamuchira 95% oxygen. "
Forbes inoti mweya wemukamuri, une 21% yeoxygen, unosanganiswa neoxygen yakanyorwa nekuti mweya wemukamuri unofemwa nemurwere unobudawo uchitenderedza mhino, zvichideredza huwandu hweoxygen inogamuchirwa.
Mazita ari pamatangi eokisijeni mumagaba anotaurawo kuti anobatsira kugadzirisa matambudziko ane chekuita nekukwira kwenzvimbo: pawebhusaiti yayo, Boost Oxygen inonyora Colorado neRockies senzvimbo dzekutakura okisijeni mumagaba.
Kana nzvimbo yacho yakakwira, kumanikidzwa kwemhepo kunoderedza, izvo zvinobatsira kutakura okisijeni kubva mumhepo kuenda kumapapu, akadaro Honigman. "Muviri wako hautore okisijeni zvakanaka sezvinoita pagungwa."
Kuderera kweokisijeni kunogona kukonzera kurwara nekukwira kwemakomo, kunyanya kune vashanyi vanoshanyira Colorado. "Vanhu vanosvika 20 kusvika 25 muzana vanofamba kubva pagungwa kuenda kunzvimbo dzakakwirira vanorwara nekukwira kwemakomo zvakanyanya (AMS)," akadaro Honigmann. Asati aenda pamudyandigere, akashanda kuCenter for High Altitude Research paYunivhesiti yeColorado Anschutz Medical Campus, kwaanoramba achiita tsvakiridzo.
Bhodhoro reBoost Oxygen rema litre mashanu rinodhura mari inosvika $10 uye rinogona kupa mweya we oxygen yakachena inosvika zana musekondi imwe chete.
Kunyange hazvo vagari vemuDenver vachiramba chirwere ichi zvakanyanya, vanhu vanosvika 8 kusvika 10 muzana vanobatwawo neAMS pavanenge vachienda kumaguta epamusoro ekutandarira, akadaro Honigman. Zviratidzo zvinokonzerwa nekudzikira kweoxygen muropa (musoro, kuda kurutsa, kuneta, kunetseka kurara) zvinowanzoonekwa mukati memaawa gumi nemaviri kusvika makumi maviri nemana uye zvinogona kukonzera kuti vanhu vatsvage rubatsiro pabhawa reoxygen.
"Zvinobatsira kuderedza zviratidzo izvi. Unonzwa zviri nani kana uchifema mweya wekufema, uye kwenguva pfupi mushure mezvo," akadaro Honigman. "Saka kana uine zviratidzo zvishoma uye ukatanga kunzwa zviri nani, zvingangokonzera kunzwa zvakanaka."
Asi kuvanhu vazhinji, zviratidzo zvinodzoka, zvichiita kuti vamwe vadzokere ku oxygen bar kuti vanzwe zororo, akadaro Honigman. Sezvo vanhu vanopfuura 90% vachijaira nzvimbo dzakakwirira mukati memaawa 24-48, danho iri rinogona kunge risingabatsiri. Vamwe masayendisiti vanotenda kuti okisijeni yakawedzerwa inongononotsa kuchinja uku kwechisikigo, akadaro.
"Maonero angu ndeekuti imhedzisiro ye placebo, iyo isina chekuita ne physiology," anobvumirana Honigman.
"Kuwana okisijeni yakawanda kunonzwika zvakanaka uye zvakasikwa, asi handifungi kuti sainzi inotsigira izvozvo," akadaro. "Pane humbowo hwechokwadi hwekuti kana uchifunga kuti chimwe chinhu chichakubatsira, chinogona kuita kuti unzwe zviri nani."
Yakatenderwa neKomisheni yeDzidzo Yepamusoro. Zviratidzo zvese zvekutengeserana ipfuma yakanyoreswa yeYunivhesiti. Inoshandiswa chete kana paine mvumo.
