He palekana paha ke hoʻohū ʻana i ka sulfur hexafluoride?
1. He mea make anei ka hexafluoride?
Sulfur hexafluoridehe physiologically inert a ua manaʻo ʻia he kinoea inert i ka lāʻau lapaʻau. Akā inā loaʻa nā mea haumia e like me SF4, lilo ia i mea ʻawaʻawa. Ke hoʻohāhā ʻia ka SF6 kiʻekiʻe, hiki mai nā hōʻailona o ka asphyxia e like me dyspnea, wheezing, ʻili polū a me nā membrane mucous, a me nā ʻūhā nui.
2. E hoemi anei ka sulfur hexafluoride i kou leo?
Ka hoololi leo osulfur hexafluoridehe kū'ē wale ia o ka hoʻololi leo o ka helium, a ʻoʻoleʻa a haʻahaʻa ke kani. Ke inhala ʻia ka sulfur hexafluoride, e hoʻopiha ka sulfur hexafluoride i nā kaula leo a puni. Ke hana mākou i ke kani a haʻalulu nā kaula leo, ʻo ka mea i hoʻoulu ʻia e haʻalulu ʻaʻole ka ea a mākou e kamaʻilio mau ai akā he sulfur hexafluoride. No ka mea ʻoi aku ka nui o ke kaumaha o ka sulfur hexafluoride ma mua o ka awelika molecular weight o ka ea, ʻoi aku ka haʻahaʻa o ka haʻalulu ma mua o ka ea, no laila e ʻoi aku ka hohonu a me ka mānoanoa o ke kani ma mua o ka maʻamau.
3. Pehea ka lōʻihi o ka manawa kūpono o ka sulfur hexafluoride?
ʻO ka nui o ke ola o ka sulfur hexafluoride microbubbles ma lalo o ka ʻole he 1 makahiki.
4. Ua ʻoi aku ka ʻino o ka sulfur hexafluoride ma mua o ke kalapona?
SF6sulfur hexafluorideʻo ia hoʻi ke kinoea ʻōmaʻomaʻo ikaika loa i ʻike ʻia. Hoʻohālikelike ʻia me ka CO2 carbon dioxide maʻamau, ʻo ka ikaika o ka SF6 sulfur hexafluoride he 23,500 mau manawa o ka CO2 carbon dioxide. Eia kekahi, ʻaʻole hiki ke hoʻoheheʻe maoli ʻia ka SF6 sulfur hexafluoride. Hiki ke hoʻomau i ka mana no hoʻokahi tausani makahiki; ʻO nā hiʻohiʻona o ka maʻalahi a me ka maʻalahi o ka hoʻohana ʻana, hui pū ʻia me nā hiʻohiʻona o ka hiki ke ola no nā kaukani mau makahiki me ka ʻole o ka decomposition kūlohelohe, e hoʻolilo i kēia kinoea i ka pollution ʻoi loa i mālama ʻole ʻia a koʻikoʻi loa i ka "hana mana ʻōmaʻomaʻo".
5. Pehea ka nui o ke kaumaha o ka sulfur hexafluoride ma mua o ka ea a mākou e hanu ai?
ʻO ke kinoea SF6 he kala ʻole, naʻaupō, ʻawaʻawa ʻole, ʻaʻole hiki ke puhi ʻia, a me ke kinoea paʻa. He kinoea koʻikoʻi ko SF6, ʻo ia hoʻi ma kahi o 5 mau manawa ʻoi aku ke kaumaha ma mua o ka ea ma lalo o nā kūlana maʻamau.
6. He laau lapaau anei ka sulfur hexafluoride?
ʻO nā hopena ʻaoʻao o ka sulfur hexafluoride ma ke kino o ke kanaka he maʻalahi a pōkole, a hiki ke hoʻōla hou me ka ʻole o ka hopena. ʻO ka Sulfur hexafluoride kahi lāʻau diagnostic i hoʻohana ʻia i nā hoʻokolohua kiʻi ultrasound, echocardiography, a me nā hoʻokolohua vascular Doppler e hoʻomaikaʻi i ka ʻike ʻana i ka maʻi. Hoʻohana ʻia ʻo Sulfur hexafluoride no ka maʻi ultrasonic a pono e hoʻohana ʻia i loko o nā keʻena olakino me nā kūlana pilikia a hoʻolako ʻia me nā limahana hoʻopakele, a pono e hoʻokomo ʻia e ke kauka. Inā loaʻa kahi hopena maʻi i ka wā a i ʻole ma hope o ka hoʻohana ʻana i ka sulfur hexafluoride, e hōʻike ʻia e like me ka erythema ʻili, bradycardia, hypotension a me ka haʻalulu anaphylactic. Inā loaʻa iā ʻoe nā hōʻailona hōʻoluʻolu ʻōnaehana a kūloko, pono ʻoe e haʻi koke i ke kauka a i ʻole e hele i ka haukapila no ka nānā ʻana. Ma hope o ka lawe ʻana i ka lāʻau lapaʻau, pono ia e nānā i loko o ke keʻena lapaʻau kūpono no ka hapalua hola e pale ai i nā hopena allergy. ʻO ka hoʻohana ʻana i ka sulfur hexafluoride i nā poʻe maʻi me ka maʻi cardiovascular hiki ke hoʻonui i ka maʻi puʻuwai.
