Unyango lwe-oksijeni ephezuluibhekiselele kwindlela yokubonelela ngonyango olusebenzayo lokuhamba kwezigulane ngokubonelela nge-high-flow, i-concentration ye-oksijeni echanekileyo kunye nokufudumala kunye nokufumisa i-air-oxygen exutywe igesi.Inokuphucula ngokukhawuleza inqanaba le-oxygenation yesigulane kunye nokugcina ukusebenza okuqhelekileyo kwe-airway mucus cilia.
Unyango oluphezulu lwe-oksijini lusetyenziswa ngokubanzi kwiklinikhi yokungaphumeleli kokuphefumula kwe-hypoxic, unyango lwe-oksijini emva kokukhutshwa, ukuhluleka kwentliziyo, isifo esingapheliyo somoya, kunye nezinye iinkqubo zokuphefumula eziphazamisayo kwiinkqubo zeklinikhi ngenxa yemiphumo ekhethekileyo yomzimba.Ngokukodwa kwizigulana ezinokusilela kokuphefumla kwe-hypoxic, unyango oluhamba ngeoksijini ephezulu lungcono kakhulu kunonyango lwe-oksijini yemveli ngokunyusa uxinzelelo lweoksijini, kwaye umphumo awukho ngaphantsi kokungena komoya ongenayo, kodwa i-HFNC inentuthuzelo kunye nonyamezelo olungcono kunoko. ukungena komoya okungangeneleliyo.Ke ngoko, i-HFNC iyacetyiswa njengonyango lokuqala lokuphefumla kwizigulana ezinjalo.
Ukuhamba okuphezulu kweNasal Cannula (HFNC)ibhekisa kuhlobo lonyango lwe-oksijini oluhambisa ngokuthe ngqo umoya kunye ne-oksijini exutywe igesi ephezulu yokuhamba-hamba koxinzelelo oluthile lwe-oxygen kwisigulane nge-catheter yeplagi yeempumlo ngaphandle kwesitywina.I-high-flow oxygen therapy (HFNC) yayisetyenziswa ekuqaleni njengenye indlela yokuxhasa ukuphefumula kwi-continuous positive pressure ventilation (NCPAP) kwaye yayisetyenziswa ngokubanzi kwi-neonatal breathing distress syndrome (NRDS), kwaye iphumelele umphumo othile.Ngokusetyenziswa okwandayo kwe-HFNC kubantu abadala, abasebenzi bezonyango bayaqaphela iingenelo zayo ezizodwa ekusebenziseni okwahlukileyo kunyango lwe-oksijini eqhelekileyo kunye nokungena komoya okungenabungozi ngoomatshini.
Unyango lwe-oksijini oluhamba ngeempumlo (HFNC) luneziphumo ezikhethekileyo zomzimba:
1. Uxinzelelo lwe-oxygen rhoqo: izinga lokuhamba kwe-oksijini elinikezelwa yinkqubo yendabuko yonyango ye-oxygen ephantsi ngokuqhelekileyo i-15L / min, ephantsi kakhulu kuneyona nto ihamba phambili yokuphefumula kwesigulane, kwaye izinga lokuhamba okunganeleyo liya kuncediswa. I-air inhaled ngexesha elifanayo, ngoko ke i-oksijini yokuphefumula I-concentration iya kuhlanjululwa kakhulu kwaye i-concentration ethile ingaziwa.Isixhobo sonyango oluphezulu lokuphefumula sinomxube we-oxygen owakhelwe ngaphakathi kwaye unokubonelela nge-gas edibeneyo ukuya kwi-80L / min, enkulu kuneyona nto iphakamileyo yokuphefumula kwesigulane, ngaloo ndlela iqinisekisa ukuxinwa rhoqo kwe-oksijeni e-inhaled kunye. ukuya kuthi ga kwi-100%;
2. Ubushushu obulungileyo kunye nefuthe lokufuma: I-HFNC inokubonelela ngegesi ephezulu kwi-37 ℃ kunye ne-100% yomswakama ohambelanayo, onenzuzo enkulu xa kuthelekiswa nonyango lwe-oxygen yendabuko;
3. Ukuhlamba indawo efileyo ye-nasopharynx: I-HFNC inokubonelela ukuya kwi-80L / min yegesi, enokuthi ikhuphe i-cavity efileyo ye-nasopharynx ukuya kwinqanaba elithile, ukwenzela ukuba ikwazi ukubonelela nge-oksijeni ephezulu kunye ne-carbon dioxide ephantsi, leyo. inokuphucula ioksijini yegazi.Indima ye-saturation ekunciphiseni i-carbon dioxide;
4. Ukuvelisa uxinzelelo oluthile lwe-airway: Abanye abaphandi baye bafumanisa ukuba i-HFNC inokuvelisa uxinzelelo oluphakathi malunga ne-4cmH2O, kwaye xa umlomo uvaliwe, unokuvelisa uxinzelelo ukuya kwi-7cmH2O.Ingabonwa ukuba i-HFNC inokuvelisa umphumo ofanayo kwi-continuous positive airway pressure (CPAP).Nangona kunjalo, ngokungafaniyo ne-CPAP, i-HFNC ijolise kwizinga lokuhamba rhoqo ukuvelisa uxinzelelo lomoya olungazinzanga, ngoko ke ekusebenziseni ikliniki, umlomo wesigulane kufuneka uvalwe ukuze ufezekise umphumo oyifunayo;
5. Intuthuzelo elungileyo kunye nokunyamezelana: Uninzi lwezifundo zifumene ukuba ngenxa yobushushu obuhle kunye nomphumo wokufuma kunye nokulula kokusetyenziswa, isixhobo sonyango lwe-oksijini yempumlo ephezulu sinobuthuthuzeleko obungcono kunye nokunyamezela kunokuba iimaski ze-oksijini ezihamba phambili kunye nokungabikho kokuphazamiseka.
I-Sepray Nasal High Flow I-Oxygen Therapy OH uchungechunge lwesixhobo sonyango lokuphefumla inikezela unyango olusebenzayo lokuhamba kwizigulana ngokubonelela ukuhamba okuphezulu, ukugxininiswa kwe-oksijini echanekileyo kunye negesi edibeneyo yomoya-oxygen efudumele kunye ne-humidified.
