Vagadziri vemitemo veDemocratic vakaratidza kushushikana pamusoro pekusiyana kwemarudzi mukuverenga kwepulse oximeter (ichidaidza iyi "nyaya yehupenyu nerufu") mwedzi miviri mushure mekunge US Food and Drug Administration (FDA) yapa yambiro yeruzhinji pamidziyo iyi neChishanu.Bvuma “zvavasingakwanisi”.
Kekutanga mumakumi emakore, vaongorori vakawana zvisizvo zvinogona kuitika pakushandisa mudziyo nevanhu vane ruvara, uye nhevedzano yezvidzidzo zvitsva zvakaburitsa data nyowani rinoratidza dambudziko uye yakapa yambiro mwedzi yakati wandei gare gare.Nguva pfupi yadarika, vaongorori veYunivhesiti yeMichigan vakaburitsa tsamba mumagazini yaDecember 2020 yeNew England Journal of Medicine, uye vakaona kuti mukana wekushaikwa kwehypoxemia neoximeter wakapetwa katatu wevarwere vatema.
"Ndokumbira utarise kuti zvinhu zvakawanda zvinogona kukanganisa kurongeka kwe pulse oximeter kuverenga, senge kusafamba zvakanaka, ganda pigmentation, ukobvu hweganda, tembiricha yeganda, kushandiswa kwefodya ikozvino, uye kushandiswa kwezvipikiri," yambiro yeFDA yakaverenga.
Haitauri zvakajeka kusiyana kwemadzinza mukururama kwemidziyo, izvo zvingaodza mwoyo varapi nevarwere vanoedza kukwevera ngwariro kuchinetso chacho.
"Zvakakosha kuziva kuti izwi rekuti' mujaho' kana 'rudzi' harina kutaurwa muFDA kutaurirana," akadaro Thomas Valley, chiremba wemapapu uye munyori wetsamba yeNEJM.“Zvakare, takaona kuti pane musiyano pakati pevarwere vechitema nevachena.Hatizivi kuti sei paine musiyano wakadai, tinofunga kuti iruvara rweganda.”
Munguva yeCovid-19 denda, pulse oximeters inoshandiswa kuyera mwero weokisijeni yave chinhu chinonyanya kukosha chekiriniki nekuti hutachiona hunokanganisa kugona kwemuviri kugadzirisa oxygen.Muzvipatara, midziyo inoita basa rinokosha pakuita zvisarudzo pamusoro pekutarisira murwere.Pakupera kwechirimo chapfuura, mushure mekunge varapi vakati wandei vakurudzira kuti zvingave zvakakosha kuchengetedza mudziyo uri kumba (semuenzaniso, zvakafanana nenzira iyo vanhu vangangoda kuchengeta iyo thermometer mukhabhati yemushonga), vhezheni yekumba yemudziyo yakatanga. kubhururuka kubva pamasherufu muma pharmacy uye Amazon nedzimwe nzvimbo dzepamhepo nekukurumidza kutengeswa kunze.
Nekudaro, bepa raZvita wapfuura (uye mareferensi ayo kune dzakateedzana zvidzidzo zvekare zvinonyora dambudziko rimwechete, kusanganisira mapepa akabudiswa muna 2005) rakakatyamadza vaongorori nevarapi, avo vakati havana kuwana chinhu ichi kuti vadzidze nezve dambudziko.Kushungurudzika nekugadziriswa kwepabonde.15 makore.
Utibe Essien, mutevedzeri wapurofesa wemishonga paYunivhesiti yePittsburgh School of Medicine, akati: “Handigoni kudavira ururami hweiyi nhamba, uye kuvimba nemichina inogona kurerekera mamwe mapoka avanhu kunovhiringidza zvikuru.”, Udza STAT kutanga kwemwedzi uno.
Mukupindura kushushikana uku, William Maisel, director weHofisi Yekuongorora Chigadzirwa uye Hunhu hweFDA's Center for Equipment uye Radiological Health, akaudza STAT kuti sangano iri riri kuongorora data riripo uye richifunga kumwe kutsvagisa kana zvichidikanwa.Akataura kuti FDA ine chivimbo chekuti maoximeter emuchipatara ane dhigirii rechokwadi, asi akawedzera kuti kune zvishandiso zvinotengeswa pamhepo uye muma pharmacy, izvi zvinogona kunge zvisiri izvo, uye agency haina kuongorora kana kubvumidza izvi.
Michael Schuddin, chiremba wepulmonologist kuMichigan State University uye munyori weNEJM tsamba, akati anofara kuti FDA yakasimbisa mukutaura kwayo kukosha kwekusavimba zvakanyanya nepulse oximeter kuita sarudzo dzekurapa.Nekudaro, akawedzera kuti anotenda kuti kusataura pachena nezvemujaho "mukana wakarasika."
Iye akati: "Nekuda kwekugumira kwechinyorwa ichi, ndinofungidzira kuti FDA inoda kusvinura muruzivo rwavo nezve misiyano yemadzinza mukurongeka kwepulse oximeter, uye kutarisa zvakanyanya panhau yekurongeka kwepulse oximeter."

Statnews, tiri kuita basa revana izvozvi?Biology nefizikisi zvinodzidziswa mumakirasi epamusoro pechikoro chepuraimari, asi munyori wechinyorwa ichi anoita seasingazive biology nefizikisi.
Sezvakataurwa nemumwe mutauri, chinhu chakanaka kuti munyori agadzirise chinyorwa kubva ku "muviri unoburitsa okisijeni" kuenda ku "muviri unoburitsa okisijeni".
Chiedza chakavharwa/kutorwa nepigment.Ruvara rwaunoona mupende ivara rinoratidzwa nependi.Naizvozvo, izvo zvaunoona zvitema, zvinoreva kuti mavara ekutanga muratidziro yekuratidzira haasi mavara ekutanga.Muchena, mavara ose anoratidzwa.Iyo oximeter inoshanda pasi pechiedza, saka inokanganiswa zvakanyanya neyakavharika mwenje / yakanyudzwa mwenje.

Munyori, ndinonyara nekuwedzera kusawirirana kwemarudzi.Chinyorwa chako chinoderedza kunaka kwe statnews.Nekudaro, panguva iyoyo iwe waive usiri wega mukuita izvi mu statnews.Pamwe kunaka kwe statnews kuri kudzikira.
Zvinhu zverudzi zveLiberal Party zvakamira rinhi pazvakapenga?Race oximeter?Zvakafanana nerusarura Covid-19.Liberalism chirwere chepfungwa chine njodzi.Aiwa, vakasununguka zvirokwazvo havasaruri.Vanobata munhu wese zvakaenzana.Vanovenga munhu wese zviri pamutemo muUnited States.
Oximeter inoshandisa mwenje wechiedza kuyera oxygen.Kana iwe uine chero zvinhu zvinovharira mwenje (zvakadai sepende, mbambo yezvipikiri, nezvimwewo), mwenje wemwenje unokanganiswa.Mufungo mushoma pane kusarurana kwemarudzi.
Vanachiremba vasingazivi vanotaura pamusoro pokusarurana kwedzinza vakapusa.Mitemo yefizikisi ibofu kurudzi uye inotongwa nemirairo yefizikisi.Apo purofesa / mudzidzisi anodzidzisa ruzivo rwekutanga rwekuparadzira chiedza, diffraction, uye kutora, anoita kunge akarara mukirasi.Handidi kuti chiremba akapusa saiye andirape.
Munyori anofanira kuita tsvakiridzo yakawanda pamusoro pekuti oximeter inoshanda sei, kwete kurangana kwechirauro.
Ko iyo dhigirii yekunyungudika kweganda remunhu uye mbambo yezvipikiri inoita basa remuviri mukutorwa kwechiedza uye kutapurirana?Ndinorangarira chinyorwa chazvino chakabudiswa muNEJM (New England Journal of Medicine) yakamutsa mubvunzo uyu.Semunhu ane hunyanzvi hwesainzi uye chiremba anodzidzira, ndinogamuchira kutariswa kwechero maonero uye ruzivo rungandibatsira kuongorora varwere.Kufunga kwangu kwekutanga ndekwekuti mukana we pulse oximeter kuverenga kuchakanganiswa nechiyero kana kusimba kwe melanin muganda nezvipikiri.Ndiyo biology uye fizikisi!Kutorwa kwechiedza che ultraviolet kuburikidza neganda uye kuti kunokanganisa sei kugadzirwa uye metabolism yevhitamini D paganda inoenderera ichijekesa pfungwa iyi.Melanin inogona kunyatso kudzikisa kunyura kwechiedza cheUVB muganda!Zvakakosha kunzwisisa uye kunzwisisa izvi.
Haasi ese sainzi ane “rusaruraganda”!Kunze kwekunge uye kusvikira taverenga, kudzidza uye kudzidza "Sainzi", isu tinofanira kungwarira kuti tisatora mhedziso dzisiridzo!
