Momwe mungasankhire zosefera zogwira ntchito kwambiri panthawi ya mliri wa COVID-19?

Chiyambire kufalikira kwa korona watsopano koyambirira kwa 2020, anthu opitilira 100 miliyoni apezeka padziko lonse lapansi ndipo anthu opitilira 3 miliyoni ataya miyoyo yawo.Mavuto apadziko lonse lapansi oyambitsidwa ndi covld-19 alowa m'mbali zonse zachipatala chathu.Pofuna kupewa kufalikira kwa coronavirus yatsopano kwa odwala, ogwira ntchito zachipatala, zida ndi chilengedwe, timadalira kwambiri njira ziwiri zosefera: zosefera za loop ndi masks mukamagwiritsa ntchito makina opumira opangira m'zipinda zogwirira ntchito ndi/kapena malo osamalira odwala kwambiri (ICU). ) Wopumira.

Komabe, pali mitundu yambiri ya zosefera zopumira pamsika.Pokambirana za kuchuluka kwa kusefera kwa opanga osiyanasiyana.kodi miyezo yawo ndi yofanana?Munthawi ya mliri wa COVID-19, mungasankhire bwanji fyuluta yopumira kwambiri?

Madokotala akuyenera kumvetsetsa tsatanetsatane wa fyuluta ya kupuma.Izi zitha kupezeka patsamba la opanga kapena hotline, zolemba zamalonda, zolemba zapaintaneti ndi m'magazini.Ma parameters ofunikira ndi awa:

●Bakiteriya ndi kusefera kwa ma virus (% -pamwamba kwambiri)

●NaCl kapena kusefera kwa mchere (% -pamwamba kwambiri)

●Kukana kwa mpweya (kutsika kwamphamvu kwa mpweya (gawo: Pa kapena cmH2O, yuniti:L/min) kutsika kwambiri)

Tiyenera kukumbukira kuti fyulutayo ikakhala pachinyezi, kodi magawo ake akale (mwachitsanzo, kusefera bwino komanso kukana mpweya) angakhudzidwe kapena kusinthidwa?

●Voliyumu yamkati (yotsika bwino)

●Kuchita kwa humidification (kutayika kwa chinyezi, mgH2O/L mpweya-kutsika kwabwinoko), kapena (kutulutsa mpweya mgH2O/L, kumakhala kokwera kwambiri).

Zida zosinthira kutentha ndi chinyezi (HME) palokha zilibe ntchito zosefera.HMEF imagwiritsa ntchito nembanemba ya electrostatic kapena nembanemba yamakina yamakina yokhala ndi kutentha ndi kusinthana kwa chinyezi komanso kusefa.Tiyenera kukumbukira kuti HMEF ikhoza kuchita bwino ntchito yosinthanitsa kutentha ndi chinyezi pamene ili pafupi ndi njira ya mpweya komanso pamalo a njira ziwiri.Amasunga madzi akamapuma ndikutulutsa madzi akamapuma.

Zosefera zopumira za Hisern Medical's Disposable breathing zili ndi lipoti loyezetsa loperekedwa ndi a Nelson Labs ochokera ku United States, ndipo limateteza odwala ndi ogwira ntchito zachipatala ku tizilombo toyambitsa matenda tomwe timamwa madzi ndi madzi.Nelson Labs ndi mtsogoleri wodziwikiratu pantchito yoyezetsa tizilombo tating'onoting'ono, akupereka mayeso a labotale opitilira 700 ndikulemba ntchito asayansi ndi antchito opitilira 700 m'malo apamwamba kwambiri.Iwo amadziwika ndi khalidwe lapadera komanso miyezo yoyesera molimbika.
