I-ventilator high-frequency (HFV) iyisentimenti esiphumelela ukuphefumula kakhulu kunomshini ovamile. I-HFVs uhlobo lwomoya wokuvuthwa kwemishini yabantwana abasanda kuzalwa . Izitha ezigula kakhulu zidinga ukwesekwa okusheshayo kwe-ventilator ukuze zifunde ukuphefumula ngokwabo. Ama-ventilators avamile angaletha ukuphefumula okungaba ngu-20 kuya kwezingu-60 ngomzuzu, kodwa ama-ventilator aphezulu angakwazi ukuletha ukuphefumula okungaba ngu-1 000 ngomzuzu.
Amafilimu aphezulu eFrequency Frequency for Lungs Fragile
Ama-ventilators aphezulu ajwayele ukusetshenziselwa izingane ezincane noma ezigula kakhulu ngaphambi kwesikhathi. Lezi zithayamthetho zinamaphaphu aphethwe kalula futhi avamile amavulenti avele abangela ukugula okungapheli kwesifo samapayipi. Ama-ventilator aphezulu aphezulu ahamba kahle emigwaqweni encane ye-preemie futhi angavimbela umonakalo wamaphaphu ezinganeni ezizodinga ukuphuza umoya isikhathi eside.
Izinhlobo ze-High Frequency Ventilators
Kunezinhlobo ezintathu ezihlukene ze-ventilators eziphezulu ezisetshenziselwa izinhloso ezihlukahlukene.
- Ama-ventilator, noma ama-oscillators (i-HFOV, isilinganiso esingu-300-3000 / iminithi)
- I-Jet ventilators (HFJV, isilinganiso esingu-100-600)
- Iziphazamisi eziphambanweni eziphezulu eziphezulu noma ukucindezela okuhle kwe-pressure (HPPV, isilinganiso 60-150 / iminithi)
Njengoba ukuhlala kwakho kwe-preemie esibhedlela kuqhubeka, ungabona eyodwa noma enye isetshenziselwa ingane yakho.
Izinkinga
Kungase kube nezinkinga kusukela ekusetshenzisweni kwama-ventilator ephezulu ezinganeni.
I-Atelectasis, ukuwa okuphelele noma okuyingxenye yamaphaphu noma i-lobe yamaphaphu, kungenye yezinkinga ezinjalo. I-hypotension noma ukucindezeleka kwegazi okungavamile kungenye inhlanganisela yama-ventilators aphezulu. Odokotela nabahlengikazi bazobheka ukushintsha izilungiselelo ze-HFV yakho ye-preemie uma lezi zinkinga zenzeka.
Ukugcoba
Njengoba zikhombisa ukuthuthukiswa, izinsana zizophucwa kancane kancane ezivini zamaphampu aphakeme futhi zifunde ukuphefumula zodwa. Isikhathi esithathayo ukutshala ingane kusukela ku-HFV kuzohluka kakhulu kuye ngokuthi bayakwazi ukuphefumula ngokwabo, ivolumu yabo yamaphaphu, nokuthi ngabe bangakanani isikhathi esingakwazi ukugcina umthamo wamaphaphu njengoba befunda ukuphefumula. Ngokuhamba kwesikhathi, njengoba ingane ikwazi ukusekela iphethini yokuphefumulela okunempilo, isikhathi esise-HFV sizokwehla uma isikhathi sokuphefumula sodwa sanda.
Yeka indlela ama-High Frequency Ventilators asiza ngayo i-Preemie yakho
Nakuba kunzima ukubukela ingane yakho idinga umshini ukuphefumla, iningi lezingane ezisanda kuzalwa zidinga lobu buchwepheshe obuphambili ukuba buphile. Ngaphandle kokuvumela ingane yakho ukuba iphefumule lapho ingenakuyenza yedwa eyedwa, izinsana zibeka i-HFVs uma kuqhathaniswa nokuvuthwa okuvamile okuye kwaboniswa ukuthi inokukhula okuncane okuhamba phambili. Ezinye izinyathelo zomsebenzi wamaphaphu nazo zitholakale zibe ngcono ezitheni eziphathwa nge-HFVs.
