Mikana yehutachiona hwezvinhu nekupfeka ffp2 mask|KENJOY

Kupfekaffp2 masikiuye kugara kure kure nevamwe kunogona kuderedza kupararira kweutachiona uye zvidimbu zvinokuvadza.Zvisinei, nekuda kwekuoma kwezvirwere zvemhepo, zvakaoma kuenzanisa kushanda kwavo, kunyanya munyaya yekubatana-kune-imwe.Pano, isu tinosuma iyo pfungwa yekumusoro muganho wekusangana-kune-imwe nehutachiona hwekufema kwevanhu.

Zvakanakira ffp2

Kuti tiverenge njodzi yekufumurwa uye hutachiona, takashandisa yakazara kufema particle size yekugovera data;expiratory flow physics;kubuda kwemhando dzakasiyana-siyana uye masikisi ekusimba akayerwa kune zvidzidzo zvevanhu;tichifunga nezve shrinkage yezvakatipoteredza zvimedu zvinokonzerwa nekuputika;rehydration, inhalability uye kuiswa mumhepo inotapukira.

Takaona kuti kune zvakajairika zvinokuvadza zvikamu zvinokuvadza uye dosi yehutachiona, nhambwe yemagariro chete, kunyangwe pa 3.0 m pakati pevatauri vaviri, yakasvika padanho repamusoro re90% yengozi yehutachiona hwehutachiona mushure memaminitsi mashoma.Kana chete vanhu vanotapurika vakapfeka masiki nekutaura kunotapukira mukati me1.5m, muganho wepamusoro wakadzikira zvakanyanya;ndiko kuti, uchishandisa masks ekuvhiya, muganho wepamusoro unosvika makumi mapfumbamwe muzana mushure memaminitsi makumi matatu, nepo kushandisa FFP2 masks kunoramba kuine makumi maviri muzana kunyangwe mushure meawa.Kana vanhu vese vari vaviri vakapfeka masiki ekuvhiya, iyo inochengetedza yepamusoro muganho inoramba iri pazasi makumi matatu muzana mushure meawa, asi kana varume vese vakapfeka masiki akakodzera eFFP2, muganho wepamusoro i0.4 muzana.Isu takagumisa kuti kupfeka iyo chaiyo ffp2 mask munharaunda inogona kupa yakanakisa dziviriro kune vamwe uye iwe pachako, uye kuita kuti nharaunda isanyanya kukosha.

Zvirwere zvinotapukira zvemhepo zvinotapuriranwa zvakananga uye zvisina kunanga kubva kune ane hutachiona kuenda kune anotapukirwa.Imwe nzira isina kunanga yekutapurirana zvidimbu zvemhepo zvinoburitswa kubva muhutachiona hwekufema, zvinoti mhino / muromo, pharynx, huro, trachea nemapapu-apa tinoshandisa izwi rekuti "zvidimbu" kureva zvimedu zvakamiswa mumhepo pa <1-mm, zvisinei nekuumbwa kwavo.

Kuumbwa uye saizi yezvimedu zvekufema kwevanhu zvinosiyana zvakanyanya uye kureba kwemakumi emakore pachiyero chehurefu.Zvakaonekwa kuti kusungirirwa uye ukuru hwezvimedu zvakaburitswa zvinoenderana zvakanyanya nerudzi rwekufema, semuenzaniso, kutaura kana kuimba zvichienzaniswa nekufema.Zviitwa zvekufema zvine chekuita nekugadzirwa kweruzha, zvinoti dzvinyiriro yeruzha, peak airflow frequency uye anodudzwa makonzonendi, anokanganisa zvakanyanya kuburitswa kwechikamu.

Zvirwere zvinotapukira zvekufema zvinogona kunge zvine kopi imwe chete kana akawanda epathogen kana abuditswa nemunhu ane hutachiona, uye pane njodzi yekutapukirwa pamushonga wakanyungudutswa kana munhu akafemerwa nemunhu ane hutachiona.Pamusoro pezvo, hunyoro hwehukama uye tembiricha zvinokanganisa kuomeswa uye kugadzika kwezvikamu zvakanyorova nekuda kwegiravhiti kana zvaburitswa mumhepo.

Kune zvakare gakava renguva refu pamusoro pezvinoreva aerosols kana madonhwe.Pamwoyo wenharo idzi ndiko kusanzwisisa kwedu kuti zvirwere zvemhepo zvinopararira sei, kana kungoti zvimedu zvinogadzirwa munzira yekufema zvinotapuriranwa nemhepo, machinjiro azvinoita nharaunda, uye kupi uye sei.Huwandu hwavo hwakaiswa mukufema turakiti reanobatwa.Zviri nyore sezvingaite senge, maitiro akadzama anobatanidzwa muchikamu chimwe nechimwe chemaitiro aya akaomarara zvakanyanya.

Izvo zviri pamusoro ndiko kuiswa kwemukana wekutapukirwa nechinhu chemukati nekupfeka ffp2 masks.Kana iwe uchida kuziva zvakawanda nezve ffp2 masks, ndapota inzwa wakasununguka kutibata.
