Ke hoʻāʻo ʻana o ka lepa

ʻO nā hoʻokolohua hoʻolahalaha ʻula ka mea e hoʻololi ai i nā ʻenekini. ʻO kēia kahi ʻāpana nui o ka hoʻāʻo ʻana i ka māmā, no ka mea ʻo ka hana nui o nā ake māmā e ʻae i ka oxygen e "diffuse" a i ʻole e hele i loko o ke koko mai nā akemāmā, a i ʻae ʻia ka carbon dioxide e "diffuse" mai ke koko i loko o nā akemāmā.

Hanu ʻoe i (ka hanu ʻana) i ka ea i loaʻa ka nui o ka carbon monoxide a me ka gas tracer, e like me ka methane a i ʻole ka helium. Mālama ʻoe i kou hanu no 10 kekona, a laila wikiwiki e hemo (hemo. Hōʻaʻo ʻia ke kinoea i lawe ʻia e hoʻoholo i ka nui o ke kinoea tracer i komo i ka hanu.

Ma mua o ka lawe ʻana i kēia hōʻike:

• Mai ʻai i ka ʻai nui ma mua o ka hoʻāʻo.
• Mai puhi iki ma kahi o 4 a 6 mau hola ma mua o ka hoʻāʻo.
• Inā ʻoe e hoʻohana i kahi bronchodilator a i ʻole nā ​​lāʻau ʻino ʻē aʻe, e nīnau i kāu mea mālama ola inā ʻaʻole hiki iā ʻoe ke hoʻohana iā lākou ma mua o ka hōʻoia.

Hoʻopili paʻa ka waha waha a puni kou waha. Kau ʻia nā lepe ma kou ihu.

Hoʻohana ʻia ka hoʻāʻo e ʻike pono ai i kekahi o nā maʻi lolo, a no ka nānā ʻana i ke kūlana o ka poʻe me nā maʻi maʻi māmā. ʻO ke ana pinepine ʻana i ka hiki ke diffusing hiki ke kōkua i ka hoʻoholo inā hoʻomaikaʻi a maikaʻi ʻole paha ka maʻi.

Pili nā hopena hōʻike maʻamau i ke kanaka:

• Makahiki
• Moekolohe
• Kiʻekiʻe
• Hemoglobin (ka protein i loko o nā hunaola ʻulaʻula e lawe i ka oxygen) pae

ʻO nā hopena kūpono ʻole ke neʻe ʻole o nā kinoea ma nā ʻāpana o ka māmā i loko o nā kīʻaha koko o ka akemāmā. Loaʻa paha kēia i nā maʻi lolo e like me:

• COPD
• Fibrosis interstitial
• Emperorism pulmonary
• Hypertension pulmonary
• ʻO Sarcoidosis
• Kahe i ka hake
• Asthma

ʻAʻohe pilikia nui.

Hiki ke hana pū ʻia nā hoʻokolohua hana pulmonary ʻē aʻe me kēia hōʻike.
