Lo mxholo ubandakanya ulwazi oluvela kwiingcali kwiinkalo zabo, kwaye uye wahlolwa ngenyaniso ukuqinisekisa ukuchaneka.
Sizibophelele ekukuboneleleni ngomxholo ophandiweyo kunye noqhutywa yingcaphephe ukukunceda wenze izigqibo ezinolwazi ngakumbi kuba uchukumisa yonke inkalo yobomi bakho bemihla ngemihla. Sihlala sizama ukukunika olona lwazi lulungileyo.
Uphononongo olutsha lubonisa ukuba le nto yekhaya eqhelekileyo inokuba sisitshixo sokuzikhusela ngcono kusulelo lwe-COVID.
Nangona imaski ye-N95 isenokuthi ifumaneke ngobhubhani we-COVID, kusenokubakho isisombululo esikrelekrele esinokukukhusela njengePPE yodidi lwezonyango. Ngokophononongo olutsha, ukosula umntwana okomileyo kunokuba sisitshixo sokwenza imaski yakho iphantse ikhuseleke njenge-N95. Qhubeka ufunde ukuze ufunde ngakumbi malunga nolu hlaselo lusekwe ngokwesayensi, kwaye ufunde ngakumbi malunga neendlela zobuchule bemaski ekufuneka uyazi, kwaye ufumanise ukuba kutheni le nto imaski yakho ingenazo ezi zinto zi-4, nceda utshintshe ube entsha, utshilo ugqirha.
Kuphononongo lwabo, abaphandi kwiDyunivesithi yaseBritish Columbia bavavanye izitayile zemaski ezininzi kunye namalaphu angama-41 ahlukeneyo ukuqonda ukuba bawavimba njani amathontsi. Emva kokuthelekisa iziphumo, bagqibe kwelokuba imaski equlathe iileya ezimbini zomqhaphu okhutshiweyo onenani eliphantsi kunye nemigangatho emithathu yokusula abantwana njengesihluzi sisebenza kakhulu ekuthinteleni ukusasazeka kwamathontsi.
"Izosulwa zabantwana zihlala zenziwe nge-spunlace kunye ne-spunbond polypropylene-efana nohlobo lwepolypropylene efumaneka kwiimaski zonyango kunye ne-N95 respirators," uGqr. Jane Wang, unjingalwazi weklinikhi kwiYunivesithi yaseBritish Columbia School of Biomedical Engineering School of Medicine, e ingxelo cacisa.
Ngapha koko, ngokukaGqr. Steven N. Rogak, unjingalwazi wobunjineli boomatshini kwiYunivesithi yaseBritish Columbia oyincutshe kwi-aerosols, “Imaski yelaphu efakwe kakuhle neyilwe kakuhle kunye nesihluzo sokusula umntwana siya kuhluza i-5-okanye i-10 micron. amasuntswana ngempumelelo ngakumbi. , Ayiyiyo imaski engu-N95 efakwe ngokungafanelekanga.”
Ngokwenqaku lophando elipapashwe kwi-BMC Pulmonary Medicine ngo-2012, umyinge wobungakanani be-aerosols yokukhohlela komntu isuka kwi-0.01 ukuya kwi-900 microns, ecebisa ukuba ukongeza isihluzo sokucoca umntwana esomileyo kwimaski eqhelekileyo yelaphu kunokwanela ukunqanda ukosuleleka kwe-COVID amathontsi okuphefumla. usasazeko.
Nangona kunjalo, iingcali zithi le ayisiyiyo kuphela indlela yokwenza iimaski zikhuseleke. Qhubeka ufunde ukuze ufunde indlela yokuqinisekisa ukuba unokhuseleko olungcono kwi-COVID. Ngokumalunga neendaba zemaski zamva nje, uGqr. Fauci uthe i-CDC inokwenza utshintsho kungekudala kule maski inkulu.
Nangona iimaski zelaphu zinokuba ngumgangatho wokuba abantu abaninzi banxibe yonke imihla, uhlobo lwempahla yemaski inokuchaphazela kakhulu ukusebenza kwayo.
Ngokutsho kwabaphandi abavela kwiYunivesithi yaseBritish Columbia, ngokufanelekileyo, umaleko wangaphandle wemaski kufuneka wenziwe ngenayiloni ephothiweyo, i-polyester satin, ikotoni edibeneyo emacala amabini okanye ikotoni ekhutshiweyo; umaleko wangaphakathi kufuneka ube yisilika ecacileyo, ikotoni enamacala amabini okanye i-quilted. Umqhaphu; kunye nesihluzo phakathi. Abaphandi bachaza ukuba ukongeza kukhuseleko olubonelelwa ngamacandelo e-mask akhankanywe ngasentla, ukuthuthuzela kwabo kunye nokuphefumula kwabo kwenza kube lula ukunxiba ixesha elide. Ukuba ufuna ukuqinisekisa ukuba ukhuselekile, kuphephe ukusebenzisa uhlobo “olungamkelekanga” lwemaski, iMayo Clinic ilumkisa.
Ii-N95 zinokuba ngumgangatho wegolide wokhuseleko kwi-COVID, kodwa nayiphi imaski oyinxibileyo ixhomekeke ekulinganeni kwayo. URogak uthe: "Kwaneemaski ze-N95, ukuba azibutywini ubuso, ziya kuphefumlela amathontsi amakhulu namakhulu aneentsholongwane ezininzi." Ucacisile ukuba iimaski ezicekethekileyo zithandwa kakhulu kwizithuba kunye nokuvuza. "Kufuneka wenze ipokotho yomoya ene-curvature enkulu ngaphambili ukuze yonke imaski itshintshe umoya." Ngolwazi oluthe kratya malunga neemaski onokuziphepha, jonga isilumkiso se-CDC ngokuchasene nokusebenzisa ezi maski zi-6.
Ukuba unxiba imaski enokusetyenziswa kwakhona, i-CDC icebisa ukuba uyihlambe kanye ngemini, ngokukhethekayo ngalo lonke ixesha isimdaka. Ngapha koko, ngokophononongo olupapashwe kwivolumu kaSeptemba ka-2020 ye-BMJ Open, "iimaski zelaphu ezihlanjiweyo zinokukhusela njengemaski zonyango."
Nangona kunjalo, ukuzama ukusebenzisa kwakhona i-N95 ngokucoca kunokuba yimpazamo ebulalayo. Abaphandi kwiDyunivesithi yaseBritish Columbia bafumanise ukuba ukuhlamba iimaski ze-N95 ngesepha kunye namanzi "kunciphisa kakhulu ukusebenza kwabo kokucoca." Ukufumana iindaba ezingakumbi zokhuseleko lwe-COVID ezithunyelwa kwi-inbox yakho, nceda ubhalisele incwadana yethu yemihla ngemihla.
Nangona zibonakala zenza ukuphefumla kube lula, ukuba imaski yakho ineendawo zokuphuma umoya, ayizukuphelisa ukusasazeka kwe-COVID. Ngokutsho kwamaZiko oLawulo lweSifo kunye noThintelo (CDC), iimaski zokungenisa umoya “zisenokungakuthinteli ekusasazeni i-COVID-19 kwabanye. Imingxuma kwizinto eziphathekayo inokuvumela amathontsi akho okuphefumla ukuba abaleke.” Phambi kokuba ubuyele kubhubhane Phambi komsitho, nceda uqaphele ukuba uGqr. Fauci uthe kuphela kwendlela ekhuselekileyo yokutya kwindawo yokutyela.
