He lāʻau lapaʻau kūikawā no ka pōkole o ka hanu - E aʻo kākou e pili ana iā Heliox

E noʻonoʻo i kahi mea kokoke iā ʻoe, he keiki liʻiliʻi paha me ka hānō a he ʻelemakule paha, hiki ʻole ke hanu, loaʻa i ka maʻi ʻōhū, a ua hanu ʻino. Pehea lā ko kākou makaʻu i ka manawa e like me ia? No laila, i kēia lā ke kamaʻilio nei mākou e pili ana i kahi lāʻau lapaʻau kūikawā e hiki i nā kauka ke hoʻohana ma nā haukapila i ia ʻano pilikia. Ua kapa ʻia kēia ʻo Heliox. Aia kekahi mau manawa hiki i kēia ke lilo i lāʻau lapaʻau e hoʻōla ai i ke ola.

I ka ʻōlelo maʻalahi, he aha ʻo Heliox?

He hui ʻana o nā kinoea ʻelua, ʻo ka helium a me ka oxygen, ʻo Heliox. Hoʻohana ʻia ia e nā limahana mālama ola, ʻo ia hoʻi, nā kauka, e mālama i nā maʻi me nā pilikia hanu nui, ʻoiai i nā kūlana pilikia. ʻO kāna hana nui ka hōʻemi ʻana i ka hoʻoikaika ʻana o ke kino e hanu ai.

E nānā i kēia manawa, ʻo ka ea a mākou e hanu mau ai he 21% oxygen a ma kahi o 78% nitrogen. ʻOiai ma ka haukapila, hāʻawi ʻia ka oxygen ma ke ʻano he oxygen maʻemaʻe a i ʻole i hui pū ʻia me ka nitrogen. Akā ma ʻaneʻi, he hiki kūikawā ko ke kinoea helium. He kinoea māmā loa ka Helium ma mua o ka nitrogen.

I mea e hoʻomaopopo ai i kēia, e lawe kākou i kahi laʻana liʻiliʻi. E noʻonoʻo ua haiki kou ala ea (ala ea) ma muli o ke anu, ka hānō, a i ʻole kekahi kumu ʻē aʻe. Ua like ia me kahi paipu wai i paʻa. I kēia manawa, inā ʻoe e hoʻāʻo e hoʻokuke i kahi wai mānoanoa, e like me ka meli, ma o kēia paipu i paʻa, pehea ka paʻakikī? Pono ʻoe e kau i ka nui o ke kaomi. He kaumaha iki ke kinoea naikokene. Akā inā ʻoe e hoʻāʻo e hoʻokuke i kahi wai māmā e like me ka wai ma o kēlā paipu? Ke kahe maʻalahi nei ia. He māmā ke kinoea helium e like me ka wai. No laila, kōkua ka helium i ka lawe maʻalahi ʻana i ka oxygen ma o nā ala ea i paʻa a haiki i loko o nā māmā.

ʻO ka Helium, e like me ka naikokene, he "kinoea inert". ʻO ia hoʻi, ʻaʻole ia e pane me nā mea ʻē aʻe o ke kino. Lawe wale ke kino i ka oxygen mai kēia hui ʻana a hanu hou i ka helium i waho. ʻO ia hoʻi, he "kaʻa" wale nō ka helium e lawe ana i ka oxygen i nā māmā.

I ka manawa hea e hoʻohana ʻia ai ʻo Heliox?

ʻO ka mea nui, ʻaʻole ʻo Heliox he lāʻau lapaʻau no kahi maʻi. Akā, he kākoʻo ia i hāʻawi ʻia e mālama i ka mea maʻi i ke kūpaʻa a hiki i ka wā e pono ai nā lāʻau lapaʻau ʻē aʻe (e laʻa me nā lāʻau hānō) a hoʻomaikaʻi ke kūlana o ka mea maʻi. Ua like ia me ka hāʻawi ʻana i kahi buoy i kekahi ke piholo lākou. Kōkua ia i ka hoʻopakele ʻana i ko lākou ola, ʻoiai e kali ana i ka hōʻea ʻana o ka hui hoʻopakele. Hōʻike ka papa ma lalo nei i kekahi o nā kūlana nui e hoʻohana ʻia ai ʻo Heliox.

Pehea e hāʻawi ʻia ai kēia lāʻau lapaʻau?

Aia kekahi mau ala e lawelawe ai i ka lāʻau lapaʻau Heliox. E hoʻoholo ke kauka ma muli o ke kūlana o ka mea maʻi.

• Ma o kahi Ventilator: Hoʻohana ʻia kēia ʻano hana ke ʻike ʻole ka mea maʻi a hāʻawi ʻia ka hanu e kahi mīkini inā ʻaʻole hiki iā lākou ke hanu iā lākou iho.
• Ma o kahi pale maka:Hoʻokele ʻia ia ma o kahi pale maka kūikawā e kau ana ma luna o ka ihu a me ka waha o ka mea maʻi.
• Ma o kahi cannula ihu: Hāʻawi ʻia ia ma o kahi ʻōmole liʻiliʻi i waiho ʻia ma lalo o ka ihu.

E hoʻololi ke kauka a i ʻole ke kauka hanu i ka pakeneka o ka helium a me ka oxygen e like me nā pono o ka mea maʻi. ʻO nā hui maʻamau i hoʻohana ʻia he 70% helium/30% oxygen a i ʻole 60% helium/40% oxygen.

He aha nā pōmaikaʻi a me nā hemahema o kēia?

Nā Pōmaikaʻi

ʻO ka pōmaikaʻi nui o kēia, e like me kaʻu i ʻōlelo ai ma mua, ʻo ia ka hoʻēmi ʻana i ka hoʻoikaika ʻana o ke kino e hanu ai. Ke paʻakikī mākou i ka hanu ʻana, hana nui ko mākou umauma a me nā ʻiʻo o ka ʻōpū. Hoʻēmi kēia i kēlā hoʻoikaika a hāʻawi i ke kino i kahi hoʻomaha. Hoʻēmi pū ia i ke ālai ʻana i ke ala o ka oxygen ma o nā ala ea i haiki.

Nā hemahema

ʻO ka hemahema a i ʻole ka pilikia nui loa, ʻo ia ka pono o kēia lāʻau lapaʻau i nā lako kūikawā a me nā limahana i aʻo ʻia e lawelawe. Hiki ke loli nā ana a me nā hoʻonohonoho o nā mīkini i hoʻohana mau ʻia e lawelawe i ka oxygen i ka wā e lawelawe ai i ka heliox. No laila, pono e ʻike pono nā kauka a me nā limahana i kēia mau loli.

Hāʻawi ʻia kēia lāʻau a hiki i ka wā e hiki ai i ka mea maʻi ke hanu maikaʻi iā ia iho a i ʻole hiki ke hoʻololi ʻia i ka lāʻau oxygen maʻamau. ʻO ka wikiwiki o ka hoʻōla ʻana ma muli o ka wikiwiki o ka hoʻomalu ʻia ʻana o ke kūlana kumu (e.g., hānō).
