Kuvhurika kwemahwindo kwenguva pfupi kunoderedza 97% yemavhairasi? Chii chinonzi shock ventilation?

Pfupiso
Tsvagiridzo yakaitwa naProfessor Vikram Niranjan inoratidza kuti kutaura kwesainzi "kubhowa imba yako," tsika yakadzika midzi mutsika yekuGermany ye Stoßlüften (kufefetera kwemhepo kunovhundutsa).
Nekuvhura mahwindo ese kuti pave nekuputika kwenguva pfupi, vagari vanogona kukurumidza kutsiva zvinosvibisa mumba—zvakaita semavhairasi, CO2, uye makemikari emumba—nemhepo itsva.
Ruzivo rwekuyedza runoratidza kuti kufefetera nguva dzose kunogona kuderedza huwandu hwehutachiona hwakafanana ne97%. Zvisinei, nguva yakakosha, kudzivirira kusvibiswa kwemotokari panguva yekumhanya-mhanya kudzivirira kufema PM2.5.
Pakupedzisira, kufefetera kwenguva pfupi inzira inobatsira zvikuru uye isingadhuri yekudzivirira kufema kwevanhu nemhuka dzinovaraidza ukuwo ichivandudza mashandiro esimba.

Chii chinonzi Stoßlüften?
Zvinonzi "kubvoora imba" zvinoreva nzira yekuvhura magonhi nemahwindo kwenguva pfupi kuti mhepo yemukati neyekunze ikurumidze kuchinjana. Izvi zvagara zvichiitwa zuva nezuva muGermany, inozivikanwa munharaunda iyi se "Stoßlüften" (shock ventilation).
Mune dzimwe nzvimbo, inotonyorwa sechisungo chekuchengetedza muzvibvumirano zvekurenda kudzivirira hunyoro nefungus.
Chikwata chaNiranjan chakasimbisawo kukosha kwayo pahutano: mhepo yemukati inounganidza hunyoro kubva mushawa nekubika, makemikari anobva muzvishandiso zvekuchenesa, uye zvidimbu zvehutachiona zvinoburitswa. Zvinosvibisa izvi zvinoungana zviri nyore mudzimba dzine insulation yakanaka, asi mhepo inofefetera kwenguva pfupi inogona kukurumidza kudzikisa nekudzinga zvinhu izvi.

Kuvhura mahwindo maawa masere pazuva
Ruzivo rwakabva mukuyedza mukirasi rwakaratidza kuti kuvhura masuo nemahwindo ese kwemaawa masere pazuva kwakaita kuti huwandu hwevanhu vadzikire ne60%. mazinga eCO2 emukati, kudzikira kwe "huwandu hwehutachiona" hwakaedzwa ne97%, uye nzvimbo dzine njodzi huru yehutachiona dzichidzikira kusvika pa15% chete yekamuri.
Mhedziso iyi yakasimbiswawo panguva yedenda reCOVID-19, apo masangano ehutano everuzhinji akasimbisa kuti kuvhura mahwindo kunogona kuderedza njodzi yekutapurirana kwezvirwere mukati meimba.
Pamusoro pezvo, chidzidzo ichi chakaona kuti mhepo isina kunaka mumba haina chekuita nezvirwere zvemapapu chete asiwo nekutadza kuisa pfungwa zvakanaka, kufunga zvishoma nezvishoma, uye njodzi dzinowedzera dzekuzvidya mwoyo nekuora mwoyo. Mhuka dzinovaraidza dzinoshanda se "nzira dzekuyambira pakutanga" dzemhando yemhepo iri mumba, dzichiwanzoratidza zviratidzo zvekutsamwiswa kwekufema vanhu vasati vaita.

Zvisinei, mumamiriro ezvinhu aya vhara mahwindo ako
Kufefetera kwakawanda hakusi nani nguva dzose.
Mhepo yekunze yemumaguta panguva yekumhanya kwakanyanya ine huwandu hwakawanda hwePM2.5 uye nitrogen dioxide.
Kuvhura mahwindo mudzimba dziri pedyo nemigwagwa mikuru panguva iyi kunogona kuwedzera kusvibiswa kwemukati, zvichikuvadza varwere vane asthma kana chirwere chemwoyo.
Niranjan anokurudzira kufefetedza mweya panguva dzisina kunyanya kudziya dzakadai sehusiku, masikati, kana mvura yanaya kana mhepo yatsva. Kufefetedza mweya kunofanira kuitwa kwenguva pfupi, uchiisa mahwindo akatarisana nemigwagwa yakanyarara kana nzvimbo dzakasvibira uye uchishandisa kufefetedza mweya kuti uvandudze kushanda zvakanaka uku uchideredza kurasikirwa nekupisa uye kushandiswa kwesimba.

Kufemesa zvakanaka kuchakubatsira kuchengetedza mari yaunoshandisa pakurapwa
Mabhenefiti ekufema mweya akakosha pahutano.
Ongororo iyi inoratidza kuti kurapa chirwere chemapapu chisingaperi (COPD) chinokonzerwa nekusvibiswa kwemhepo mumba kunodhura zviuru zvemadhora pagore, nepo mari yekudziyisa yekuvhura hwindo kwemaminitsi mashanu munguva yechando iri mashoma.
Kumhuri zhinji, kubhowekana kwenguva pfupi, kusingatarisirwi, uye kwakanyatsorongeka zvakanaka inzira inoshanda yekudzivirira hutachiona uye kusvibiswa kwemhepo.
Kunyange hazvo tsika ye "kubvoora imba" ine zita rinosetsa, pfungwa dzayo huru ndeyesainzi. Kunyanya munguva dzemavhairasi, dzimba dzisina mhepo dzinoita kuti kusvibiswa kuwedzere. Muchina Wemhepo inopa dziviriro yehutano kumhuri yese, kusanganisira mhuka dzinovaraidza.

Mibvunzo Inowanzo bvunzwa
1. Musiyano mukuru weStoßlüften ndeupi?
Kuchinjana kwemhepo kwemaminetsi mashanu kusvika gumi, kusiyana nekupwanya hwindo kwemaawa mashoma.
2. Sei mhuka dzinovaraidza dziri "nzira dzekunyevera vanhu nekukurumidza"?
Masisitimu avo ekufema anonyanya kubatwa nehutachiona uye ari pedyo nezvinosvibisa zviri pasi pevhu kupfuura vanhu.
3. Maminitsi gumi akakwana here kuti ashande zvakanaka?
Ehe. Kusiyana kwedzvinyiriro kunobvisa CO2 nemavhairasi nekukurumidza pasina kutonhora kwechivako.
4. Ndirini pandinofanira kudzivisa "kupwanya" imba?
Munguva yekumhanya-mhanya (PM2.5/NO2) kana kana uchigara pedyo nemotokari dzakawanda.
