Amathuba okutheleleka ngezinhlayiyana ngokugqoka imaski ye-ffp2|KENJOY

Ukugqokaffp2 imaskinokugcina kude nomphakathi kunganciphisa ngempumelelo ukusabalala kwamagciwane nezinhlayiya eziyingozi.Kodwa-ke, ngenxa yobunzima bezifo ezihamba emoyeni, kunzima ukulinganisa ukusebenza kwazo, ikakhulukazi esimweni sokuxhumana okukodwa.Lapha, sethula umqondo womkhawulo ophezulu wokuxhumana nomuntu oyedwa nezinhlayiya zokuphefumula ezithathelwanayo zomuntu.

Izinzuzo ze-ffp2

Ukuze ubale ubungozi bokuchayeka kanye nokutheleleka, sisebenzise idatha yokusabalalisa usayizi wezinhlayiyana zokuphefumula;i-expiratory flow physics;ukuvuza kwezinhlobo ezahlukahlukene kanye namamaski okuqina akalwa ezifundweni zabantu;kucatshangelwa ukushwabana kwezinhlayiya zemvelo ezibangelwa ukuhwamuka;ukubuyisela amanzi emzimbeni, ukuhogela kanye nokufakwa kumzila womoya osengozini.

Sithole ukuthi kumthamo wezinhlayiyana eziyingozi ezijwayelekile kanye nethamo lokutheleleka, ibanga lomphakathi kuphela, ngisho noma libe ngu-3.0 m phakathi kwezipikha ezimbili, elifinyelele umkhawulo ophezulu wama-90% wengozi yokutheleleka ngebhaktheriya ngemva kwemizuzu embalwa.Uma kuphela abantu abathintekayo begqoka izifihla-buso ezinenkulumo ethathelwanayo phakathi kwe-1.5m, umkhawulo ongaphezulu uphansi kakhulu;okungukuthi, kusetshenziswa imaski yokuhlinza, umkhawulo ongaphezulu ufinyelela kumaphesenti angama-90 ngemuva kwemizuzu engama-30, kuyilapho kusetshenziswa imaski ye-FFP2 kuhlala cishe ngamaphesenti angama-20 ngisho nangemva kwehora.Lapho bobabili abantu begqoka imaski yokuhlinza, umkhawulo ophezulu oqinile uhlala ungaphansi kwamaphesenti angama-30 ngemuva kwehora, kodwa lapho womabili amadoda egqoka imaski efanelekile ye-FFP2, umkhawulo ongaphezulu ungamaphesenti angu-0.4.Siphethe ngokuthi ukugqoka imaski elungile ye-ffp2 emphakathini kunganikeza isivikelo esihle kakhulu kwabanye kanye nawe, futhi kwenze ibanga lomphakathi lingabaluleki kangako.

Isivinini sokusakaza komoya

Izifo ezithathelwanayo zomoya zidluliselwa ngokuqondile nangokungaqondile zisuka kothelelekile ziye kulowo ongenwa yizifo.Umzila owodwa ongaqondile wokudlulisela izinhlayiya eziphuma emoyeni eziphuma emgudwini wokuphefumula othathelwanayo, okuyikhala / umlomo, umphimbo, uqhoqhoqho namaphaphu-lapha sisebenzisa igama elithi "izinhlayiya" ukubhekisela ezinhlayiyeni ezimiswe emoyeni ku-< 1-mm, kungakhathaliseki ukuthi zakhiwe kanjani.

Ukwakheka nobukhulu bezinhlayiya zokuphefumula komuntu ziyahlukahluka futhi zithatha amashumi eminyaka ngesilinganiso sobude.Kutholakale ukuthi ukugxila kanye nobukhulu bezinhlayiya ezikhishwe umoya zincike kakhulu kuhlobo lomsebenzi wokuphefumula, isibonelo, ukukhuluma noma ukucula uma kuqhathaniswa nokuphefumula.Imisebenzi yokuphefumula ehlobene nokukhiqizwa komsindo, okungukuthi ingcindezi yomsindo, imvamisa yokugeleza komoya ephakeme kakhulu nongwaqa abaphimiselekayo, kuthinta kakhulu ukukhishwa kwezinhlayiyana.

Izinhlayiya zokuphefumula ezithathelwanayo zingase zibe nekhophi eyodwa noma eziningi ze-pathogen lapho zikhishwa ngumuntu onaleli gciwane, futhi kunengozi yokutheleleka ngethamo elimuncwayo lapho ehogelwa umuntu othintekayo.Ngaphezu kwalokho, umswakama ohlobene nezinga lokushisa kuthinta ukomiswa kanye nokuhlaliswa kwezinhlayiya ezimanzi ngenxa yamandla adonsela phansi lapho zikhishwa zingene endaweni ezungezile.

Kukhona futhi impikiswano ende mayelana nencazelo yangempela yama-aerosol noma amaconsi.Umnyombo walezi zingxabano ukuntula kwethu ukuqonda ukuthi izifo ezihamba emoyeni zisakazeka kanjani, noma nje ukuthi izinhlayiya ezikhiqizwa emgudwini wokuphefumula othathelwanayo zidluliselwa kanjani emoyeni, zishintsha kanjani endaweni ezungezile, nokuthi zisakazeka kuphi futhi kanjani.Inani labo elifakwe emgudwini wokuphefumula walabo abathintekayo.Nakuba kungase kubonakale kulula, izindlela ezinemininingwane ezihilelekile engxenyeni ngayinye yalezi zinqubo ziyinkimbinkimbi kakhulu.

Okungenhla ukwethulwa kwamathuba okutheleleka ngezinhlayiya ngokugqoka imaski ye-ffp2.Uma ufuna ukwazi okwengeziwe ngamamaski e-ffp2, sicela ukhululeke ukusithinta.
