Mai ka hoʻomaka ʻana o ka maʻi maʻi COVID-19 ma mua o 2 mau makahiki i hala aku nei, ua hana nui nā mea hanu N95 i nā lako pale pilikino (PPE) o nā limahana mālama olakino a puni ka honua.
Ua hōʻike ʻia kahi noiʻi i ka makahiki 1998 ua hiki i kahi National Institute of Occupational Safety and Health (NIOSH)-approved N95 mask ke kānana i ka 95 pakeneka o nā mea ea ea, ʻoiai ʻaʻole ia i ʻike i ka maʻi. Hoʻoholo ka mask i kona hiki ke kānana i nā ʻāpana ea.
I kēia manawa, ua ʻōlelo kahi hui noiʻi mai ke Kulanui ʻo Monash ma Australia, ʻo nā masks N95 i hoʻāʻo pono ʻia i hui pū ʻia me kahi ʻōnaehana kānana HEPA portable e hāʻawi i ka pale maikaʻi loa mai nā ʻāpana virus ea.
Wahi a ka mea kākau alakaʻi ʻo Dr Simon Joosten, Monash University Monash Health Medicine Senior Research Fellow a me Monash Health Respiratory and Sleep Medicine Physician, ʻelua mau pahuhopu nui ka noiʻi.
ʻO ka mea mua e "helu i ka nui o ka poʻe i haumia me nā aerosol viral ʻoiai e hoʻohana ana i nā ʻano masks like ʻole a me nā pale pale maka, nā ʻaʻahu a me nā mīkina lima".
No ke aʻo ʻana, ua ana ka hui i ka pale i hāʻawi ʻia e nā masks surgical, N95 masks, a me nā masks N95 i hoʻāʻo ʻia.
Hoʻopale ʻia ka mea hoʻohana mai nā kulu nui, kōkua pū kekahi i ka pale ʻana i ka mea maʻi mai ka hanu ʻana o ka mea hoʻohana.
ʻOi aku ka maikaʻi o nā masks N95 i ka maka ma mua o nā masks.
No ka mea ʻokoʻa ke ʻano o ka helehelena o kēlā me kēia kanaka, ʻaʻole kūpono nā nui a me nā makamaka N95 a pau.
Pono pono ka mask N95 i ho'āʻo maikaʻi ʻia, e hāʻawi ana i kahi "sila" ma waena o ka lihi o ka mask a me ka maka o ka mea hoʻohana.
Ua haʻi ʻo Kauka Joosten i ka MNT ma kahi o ka hoʻāʻo ʻana i nā masks like ʻole, makemake ka hui e hoʻoholo inā hiki i ka hoʻohana ʻana i nā kānana HEPA portable ke hoʻonui i nā pono o nā lako pale pilikino e pale ai i ka mea hoʻohana mai ka maʻi aerosol viral.
Hoʻopau nā kānana ʻo High Efficiency Particulate Air (HEPA) i ka 99.97% o nā ʻāpana lewa 0.3 microns ka nui.
No ke aʻo ʻana, ua hoʻonoho ʻo Dr. Joosten a me kāna hui i kahi limahana olakino, a ua komo pū i ka hoʻonohonoho hoʻokolohua, i loko o kahi lumi hauʻoli i hoʻopaʻa ʻia no 40 mau minuke.
ʻOiai i loko o ka lumi, ua komo nā mea komo i ka PPE, me nā mīkina lima, ka ʻaʻahu, ka pale alo, a me kekahi o nā ʻano masks ʻekolu - ʻokiʻoki, N95, a i ʻole N95 i hoʻāʻo ʻia. PPE, ʻaʻole lākou i ʻaʻahu i nā maka.
Ua hōʻike nā mea noiʻi i nā limahana mālama ola i kahi nebulized version o ka phage PhiX174, kahi maʻi hoʻohālike ʻino i hoʻohana ʻia i nā hoʻokolohua ma muli o kāna genome liʻiliʻi.
Ma hope o kēlā me kēia hoʻokolohua, lawe ka poʻe noiʻi i nā ʻili ʻili mai nā wahi like ʻole ma ke kino o ka limahana olakino, me ka ʻili ma lalo o ka mask, ka ihu o loko, a me ka ʻili ma ka forearm, ʻāʻī a me ka lae. lā.
Ma hope o ka nānā ʻana i nā hopena, ua ʻike ʻo Kauka Joosten a me kāna hui i ka wā e hoʻohana ai nā limahana mālama ola i nā masks surgical a me nā masks N95, ua nui ka maʻi i loko o ko lākou mau maka a me nā ihu. ua ʻaʻahu ʻia.
Eia hou, ua ʻike ka hui i ka hui pū ʻana oHEPA kānana, nā maka N95 i ho'āʻo kūpono ʻia, nā mīkina lima, nā ʻaʻahu a me nā pale pale maka i hoʻemi ʻia ka helu virus i kahi kokoke-zero pae.
Manaʻo ʻo Kauka Joosten e kōkua nā hopena o kēia haʻawina e hōʻoia i ke koʻikoʻi o ka hoʻohui ʻana i nā mea hanu N95 i hoʻāʻo pono ʻia me ka kānana HEPA no nā limahana mālama ola.
"Hōʻike ia i ka wā e hui pū ʻia me kahi kānana HEPA (13 hoʻololi kānana ea i kēlā me kēia hola), ʻo ka hele ʻana i ka hoʻāʻo kūpono ʻo N95 hiki ke pale aku i ka nui o nā aerosol viral," wehewehe ʻo ia.
"[A] ke hōʻike nei he mea koʻikoʻi kahi ala i ka pale ʻana i nā limahana mālama olakino a hiki i ka kānana HEPA ke hoʻonui i ka pale no nā limahana mālama olakino ma kēia mau hoʻonohonoho."
Ua kamaʻilio pū ʻo MNT me Dr. Fady Youssef, he pulmonologist i hōʻoia ʻia, kauka a me ka mea mālama koʻikoʻi ma MemorialCare Long Beach Medical Center ma Long Beach, Kaleponi, e pili ana i ke aʻo ʻana.
"ʻO nā hōʻailona like ʻole a me nā hiʻohiʻona o nā masks N95 e koi i kā lākou hoʻāʻo ponoʻī - ʻaʻole ia hoʻokahi-nui-pono-a pau," wehewehe ʻo Kauka Youssef.Inā ʻoe e ʻaʻahu nei i kahi mask ʻaʻole kūpono iā ʻoe, he mea liʻiliʻi ia e pale aku iā ʻoe.
E pili ana i ka hoʻohui ʻana okānana HEPA lawe lima, Ua ʻōlelo ʻo Kauka Youssef i ka wā e hana like ai nā hoʻolālā mitigation ʻelua, he mea kūpono ia e ʻoi aku ka nui o ka synergy a me ka hopena ʻoi aku.
"Hoʻohui ia i nā hōʻike hou aʻe [...] e hōʻoia i ka nui o nā papa hana mitigation e mālama i nā poʻe maʻi me nā maʻi ea e hōʻemi a manaʻolana e hoʻopau i ka ʻike ʻana i nā limahana mālama olakino e mālama nei iā lākou," i hoʻohui ai ʻo ia.
Ua hoʻohana ka poʻe ʻepekema i ka nānā ʻana i ka laser e hoʻāʻo ai i ke ʻano o ka pale maka homemade ʻoi aku ka maikaʻi i ka pale ʻana i ka hoʻokuʻu ʻana i ka ea…
ʻO nā hōʻailona nui o COVID-19 ʻo ke kuni, ka ʻū maloʻo a me ka pōkole o ka hanu. E aʻo hou e pili ana i nā hōʻailona ʻē aʻe a me nā hopena i manaʻo ʻia ma aneʻi.
ʻaneʻane nā mea hoʻomaʻi ma nā wahi a pau, a hiki iā lākou ke hoʻopōʻino i kekahi organism. Maʻaneʻi, e aʻo hou e pili ana i nā maʻi virus, pehea lākou e hana ai, a pehea e pale ai.
ʻO nā maʻi maʻi e like me ka novel coronavirus he maʻi lele loa, akā he nui nā ʻanuʻu i hiki i nā keʻena a me nā kānaka ke hana e kaupalena i ka laha ʻana o kēia mau maʻi.
