Umgomo wokuvimbela uthuli lwemaski yezokwelapha

Izifihla-buso zezokwelaphazenziwe ngezindwangu ezingalukiwe. Le nto ayidingi ukulukwa. Yenziwe ngeminye imicu. Ivamise ukwenziwa ibe imaski yezendlalelo ezi-2, izendlalelo zomlomo ezinezingqimba ezi-3, namamaski ekhabhoni acushwe izendlalelo eziningi.

Amamaski ezokwelapha angavimbela ngokuphumelelayo uthuli olucolile emoyeni, ikakhulukazi othulini oluphefumulayo olungaphansi kwama-microns angu-2.5, ngoba uthuli lwalo sayizi wezinhlayiyana lungangena ngokuqondile ku-alveoli, olunomthelela omkhulu empilweni yomuntu. Isimiso sokusebenzisa imaski yezokwelapha yukuthi lapho uthuli ludlula i-gauze, luzodlula ungqimba lwezithiyo, futhi uthuli luzofakwa ku-gauze, ukuze umoya omusha ungene ohlelweni lokuphefumula.
