Type II kutadza kufema kunoda mhepo inofefetera

Basa remapapu revarwere vane COPD richaderera zvishoma nezvishoma nekufamba kwenguva.COPD inogona kunge isina zviratidzo pakutanga, asi ichave yakakomba sezvainokura.Kazhinji, inotanga kuumba 1 kutadza kufema uye kunyora 1 kutadza kufema.Kune chete hypoxia, asi hapana dambudziko rekuchengetedza carbon dioxide.Panguva ino, dambudziko guru remurwere ndeye hypoxia, saka panguva ino, kurapwa kweokisijeni kumba kunonyanya kushandiswa, inova ndiyo yatinowanzo kudaidza kuti imba okisijeni jenareta.

Paunenge uchikura kubva kurudzi rwekutanga kusvika kurudzi rwechipiri kutadza kufema, murwere haangotamburi ne hypoxia chete asiwo nekuchengetedza kabhoni dhaimoni.Izvi zvinodaro nekuti madiki emhepo anowedzera kuvharika nekusimudzira, uye gasi rekuchinjana simba rinowedzera kuderedzwa.Kuwedzera kabhoni dhaikisaidhi kwakaoma kuburitsa kubva mumuviri, uye zvinokonzeresa kuchengetwa kwekabhoni dhaikisai mukati menguva refu.Panguva ino, kurapwa kweventilator kunodiwa.

Nzira yekutonga kana iri carbon dioxide retention

Nzira yakanakisa yekuchengetedza carbon dioxide ndeyekuenda kuchipatara kunoongororwa arterial blood gas.Kuburikidza neiyo arterial yeropa gasi kuongororwa, iwe unogona kuziva iyo okisijeni chikamu chekumanikidza, kabhoni dhaidhiyo chikamu chekumanikidza uye zvimwe zviratidzo.Kazhinji, iyo carbon dioxide partial pressure inodarika 45 kuti ive isina kujairika.

Iyo ventilator inoderedza sei dambudziko rekuchengetedza kabhoni

Iyo mhepo inofefetera inopa inoenderera mberi inomanikidza kufefetera kunzira yemurwere kuti iwedzere mhepo yemurwere uye kuona kuchinjana kwakanaka kwegasi remurwere.Nemhaka yokuti nzira duku yemhepo haina kujeka, chirwere chisingaperi chechirwere chechirwere chechirwere chechirwere chinongogara chisina oxygen mukutanga uye chinokura kusvika kune imwe nguva.Kwete chete iyo oxygenation ine urombo, asi zvakare inotungamira kune kumwe kuderera kwemhepo.Kuderera kwemhepo yekufefetera hakuzongowedzera dambudziko re hypoxia, asi zvakare kunotungamirira kune yakashata gasi kuchinjanisa uye kuoma kuburitsa gasi rekubuda kubva mumuviri.

Basa remuchina nderekuwedzera mhepo yemurwere.Mukana wekufema unowedzera dzvinyiriro apo murwere anofema, zvichibatsira murwere kufema gasi rakawanda.Paunenge uchifema, mukana wekufema unoderedza kudzvanywa uye unoshandisa mutsauko wekumanikidza pakati pemapapu nekunze kubatsira Murwere anoburitsa gasi rekubuda kubva mumuviri, kuitira kuti mhepo yekufema iwedzere, kuitira kuti kabhoni dhayokisaidi yakawandisa isaunganidze mumuviri. .Uyu ndiwo musimboti wekuti mhepo inofefetera inobatsira murwere kuderedza njodzi yekuchengetwa kwekabhoni dhaikisaidhi.

Iyo mhepo inofefetera haingodzikisi kabhoni dhaikisaidhi yemurwere zvishoma, asi zvakare inovandudza murwere oxygenation.Kana murwere ari murudzi II kufema kutadza nguva, hazvikurudzirwe kurega kuyerera kupfuure 2L/min mune general oxygen therapy, nekuti kugona kwemurwere kwekufema panguva ino hakuna kunaka, kufemedza okisijeni yakawandisa kunowedzera njodzi. ye carbon dioxide retention, saka zviri panguva ino.Kuyerera kweokisijeni kuderera, kuyerera kweokisijeni kuderera hakuna kunaka pakuvandudza kubatanidzwa kweokisijeni.Naizvozvo, panguva ino, zvinowanzokurudzirwa kuwedzera kuyerera kweokisijeni uchishandisa vhezheni.Inokurudzirwa kutenga jenareta yeokisijeni isingasviki 5L yekushandiswa kwemhuri yeakisijeni jenareta.Paunenge uchishandisa mhepo inoputika yakasanganiswa nejenareta yeokisijeni, nokuti mhepo inoputika inowedzera mhepo uye mhepo inoputika inoderedza chikamu chemukati weokisijeni, kukwira-kuyerera kweokisijeni hakukonzeri njodzi yekuchengetedza carbon dioxide.

Mushure mekuedza kwakawanda kwekudzora dhata, Guangzhou Hepuler Ventilator R&D Center yakasimbisa kuti kurapwa kwemumba kunogona kuderedza kufema kwevarwere, kuderedza huwandu hwekuiswa muchipatara nekurwiswa kwakanyanya, uye kugadzirisa hupenyu hwevarwere veCOPD.

Iyo inogara ichiita vhoriyamu basa mu8-series ventilator yakagadziridzwa neHepuler inogona kuseta iyo yakanangwa tidal volume kuitira kuti varwere vane COPD vagone kuchengetedza yakakwana miniti yekufefetedza kuti isangane negasi rekuchinjana zvinodiwa nevarwere kwenguva yakareba uye kuvandudza kabhoni dhaikisaidhi.Kuchengetedza, nezvimwewo.
