Na tšilafalo ea moea e ama kotsi ea OHCA? Boithuto bo entsoeng ke University of Sydney

Hona joale ha COVID-19 e khutlela morao, lefatše le ntse le leka butle ho khutlela mesebetsing ea lona e tloaelehileng, 'me tšilafalo e tla eketsa boteng ba eona moeeng hape. Sengoliloeng sena re lakatsa ho sekaseka karolo e mabapi le EMS le ts'ilafalo. Na tšilafalo ea moea e ka eketsa kotsi ea ho ts'oaroa ha pelo ka ntle ho sepetlele (OHCA)? Ha re shebeng thuto ea machabeng!

Phuputso e entsoeng machabeng e fumane hore, esita le ho pepesetsoa nako e khuts'oane ea lintlha tse ngata tse bobebe PM2.5, ho na le menyetla ea ho ts'oaroa ha pelo le sepetlele (OHCA) ntle le sepetlele. Phuputso eo e hlokometse hore kopano le batho ba nang le litšilafalo tsa moea (tšilafalo ea moea) joalo ka ba tsoang ho chesoa ka mashala / meepo, lihlahla tsa mollo le makoloi, haholoholo.

Science Daily, e tlalehileng phuputso ena, e phatlalalitse hore lipatlisiso tsa naha ka bophara tsa data li tsoa Japane, e khethiloe bakeng sa ho e lekola haholo, bongata le boleng ba moea, boo ho lumeloang hore ke bona bo boholo ho feta bohle. E fana ka bopaki bo felletseng ba kamano pakeng tsa ho ts'oaroa ha PM2.5 le pelo, haholo-holo ho ts'oaroa ha sepetlele sa lefu la pelo (OHCA).

Kamano lipakeng tsa ts'ilafalo ea moea le OHCA - Pokello ea data

Univesithi ea Sydney etella pele thuto le Liphetho li hlahisoa ho The Lancet Planetary Health. Phuputso e ikemiselitse ho tseba mekhatlo pakeng tsa ho pepesehela tšilafalo ea moea e haufi le ketsahalo ea OHCA (ho ts'oaroa ha pelo ka ntle ho sepetlele).

Moprofesa Kazuaki Negishi, ngaka ea pelo le Hlooho ea Bongaka ea Univesithi ea Sydney School of Medicine le sengoli se phahameng, o phatlalalitse hore lipatlisiso tse bohlokoa tse entsoeng kamanong e pakeng tsa ts'ilafalo ea moea le linyeoe tse matla tsa pelo (joalo ka OHCA), li ne li sa fella ebile li sa lumellane. Kajeno re ka re li-OHCA tse fetang 90% li etsahetse maemong a PM2.5 a tlase ho feta tataiso ea WHO, karolelano ea letsatsi le letsatsi ea li-micrograms tse 25 ka mitha oa khubiki (? G / m3).

Kotsi ea ho ts'oaroa ha pelo le mofets'e sepetlele (OHCA)

Moprofesa Negishi o hlalosa hore ho ts'oaroa ha pelo le kamohelo ea sepetlele (OHCA) ke hlahala e kholo ea bongaka. Ka tlase ho motho a le mong ho ba 10 o pholoha Liketsahalo tsena ebile ho bile le bopaki bo ntseng bo eketseha ba ho hokahana le tšilafalo ea moea e matla haholo, kapa ntho e ntle e kang PM2.5.

Boithuto bona bo hlahlobisitse ho kotula linyeoe tse ka bang kotara ea milione tse amanang le ho tšoaroa ke pelo le bana (OHCA) le khokahano e hlakileng ea yo yhe ea tšilafalo e mpe ea moea. Phatlalatso e bohlokoa: thuto e ts'ehetsa bopaki ba morao-rao ba hore ha ho na boemo bo sireletsehileng ba tšilafalo ea moea, kaha liphuputso tsa bona li bontšitse hore ho na le kotsi e eketsehileng ea ho ts'oaroa ha pelo le ha boleng ba moea ka kakaretso bo kopana le litekanyetso.

Taba ea bohlokoa ke hore tšilafalo ea moea lefatšeng ka bophara e tla eketseha ka lebaka la likoloi tse ntseng li eketseha le likoluoa tse kang lihlahla tsa mollo.

Ho ntlafatsa boleng ba moea ke tharollo ea li-riks tse phahameng tsa OHCA
