ʻO ka HFNC kahi mea hoʻolaha oxygen hou, nona nā hana o ka hana e hāʻawi i nā hopena maikaʻi ma luna o nā ʻōnaehana oxygen maʻamau.Manaʻo ʻia he nui nā hopena physiological: hoʻomaikaʻi ʻo ia i ka oxygenation, hoʻokō ʻana i ka māmā ikaika, homogeneity a hoʻopau i ka nui o ka māmā expiratory;e ho'emi ana i ka anatomical dead space a ho'oulu i ke ea ea maika'i e hiki ke ho'emi i ka hanu hanu, ka hana o ka hanu, a ho'onui i ka oluolu o ka ma'i.

ʻO ke ʻano o ke kākoʻo hanu non-invasive i hoʻohālikelike ʻia me ka hoʻomau ʻana i ke ea ea maikaʻi (CPAP).

Ke hoʻohana ʻia ʻo HFNC e hāʻawi i ka oxygen, ʻoi aku ka kiʻekiʻe o nā kahe kahe ma mua o ka hiki ke loaʻa me ka cannula nasal kuʻuna.ʻO kēia ka hopena i ka hāʻawi nui ʻana o ka oxygen i kuhikuhi ʻia i loko o ka māmā, a me ka emi ʻana o ka ea o ka lumi.ʻO ka oxygen āu e makemake ai e hāʻawi aku i kāu poʻe maʻi ʻaʻole kūpono i ka hopena like o ka dilution!

ʻO nā hopena physiological nui o ka HFNC ʻo ka mālama ʻana i kahi alveolar FiO2 paʻa i ʻike ʻia, ka humidification maikaʻi loa o ka mucosa ea, ka hoʻemi ʻana o ka wahi make, ka hana ʻana o ka hopena hopena hopena maikaʻi (PEEP), ka hopena e hāʻawi i ka hoʻemi ʻana o ka hanu hanu a i loko. ka hana hanu.

I ke kaua kūʻē iā Covid-19 ma Wuhan i 2020, ʻo 70% kiʻekiʻe kiʻekiʻe mai ka micomme.

I ka makahiki 2020, ua helu ʻo micomme i ke ono o ka lawe ʻana aku i nā mea hanu olakino ma Kina.

ʻO ka hui ʻana o ka oxygen-gas i kūkulu ʻia e kāohi pono i ka oxygen a hoʻoponopono i ka ʻike oxygen.

ʻO ka hoʻolālā ala ea kū hoʻokahi, ʻaʻohe pono no ka disinfection, hoʻemi i ka manawa huli o nā mea hana a me ka hana o nā limahana lapaʻau.

Pūnaehana hoʻomalu wai naʻauao, mālama pono i ka pae wai maikaʻi loa i loko o ke keʻena wai.
