Imishini yokuphefumula - izinsana

I-mechanical ventilator ngumshini osiza ngokuphefumula. Lo mbhalo ukhuluma ngokusetshenziswa kwemishini yokuphefumula ezinganeni.

KUNGANI KUSETSHENZISWA ISIPHEPHELO SOMSHINI?

Umshini wokuphefumula usetshenziselwa ukunikeza ukusekelwa kokuphefumula kwezingane ezigulayo noma ezingakavuthwa. Izingane ezigulayo noma ezizalwe ngaphambi kwesikhathi ngokuvamile azikwazi ukuphefumula ngokwanele ngokwazo. Bangadinga usizo kumshini wokuphefumula ukuze banikeze "umoya omuhle" (i-oxygen) emaphashini nokususa umoya "omubi" ophefumulayo (i-carbon dioxide).

USETSHENZISWA KANJANI UMDLALO WOKUSETSHENZISWA KOMSHINI?

Umshini wokuphefumula umshini oseceleni kombhede. Inamathele kushubhu yokuphefumula efakwa ku-windpipe (trachea) yezingane ezigulayo noma ezingakafiki ezidinga usizo lokuphefumula. Abanakekeli bangalungisa umshini wokuphefumula lapho kudingeka. Ukulungiswa kwenziwa ngokuya ngesimo sengane, izilinganiso zegesi yegazi, nama-x-ray.

BUYINI UBUNGOZI BESIVIVINYO SOKUSEBENZA?

Iningi lezingane ezidinga usizo lokuphefumula zinezinkinga ezithile zamaphaphu, kufaka phakathi amaphaphu angavuthiwe noma anezifo, asengozini yokulimala. Kwesinye isikhathi, ukuletha umoya-mpilo ngaphansi kwengcindezi kungalimaza amasaka omoya abuthaka (alveoli) emaphashini. Lokhu kungaholela ekuvuzeni komoya, okungenza kube nzima kumshini wokuphefumula ukusiza ingane iphefumule.

• Uhlobo oluvame kakhulu lokuvuza komoya lwenzeka lapho umoya ungena esikhaleni esiphakathi kwamaphaphu nodonga lwesifuba sangaphakathi. Lokhu kubizwa ngokuthi yi-pneumothorax. Lo moya ungasuswa ngeshubhu elibekwe esikhaleni kuze kuphole i-pneumothorax.
• Uhlobo olungajwayelekile kakhulu lokuvuza komoya lwenzeka lapho kutholakala amaphakethe amaningi amancane wezicubu zamaphaphu azungeze amasaka omoya. Lokhu kubizwa ngokuthi yi-pulmonary interstitial emphysema. Lo moya awukwazi ukususwa. Noma kunjalo, imvamisa ihamba kancane yodwa.

Ukulimala kwesikhathi eside kungenzeka futhi ngoba amaphaphu asanda kuzalwa awakakhuli ngokuphelele. Lokhu kungaholela kwisifo samaphaphu esingapheli esibizwa nge-bronchopulmonary dysplasia (BPD). Yingakho abanakekeli beqaphelisisa ingane. Bazozama "ukuncelisa" umntwana oksijini noma banciphise amasethingi omoya lapho kungenzeka khona. Ukuthi ukuphefumula okunikezwayo kungakanani kuzoxhomeka ezidingweni zengane.
