Njengesinye sezifo ezine ezingapheliyo ezinezinga eliphezulu lokufa, isifo esingapheliyo semiphunga sinokukhula kancinci ukusuka kobuncinci ukuya kobunzima.Xa isifo siqhubela kwinqanaba elithile, kuyimfuneko ukusebenzisa ai-ventilator engena-invasiveukunceda ukungena komoya, kodwa indlela yokulinganisa eli nqanaba

Uhlobo lwe-II lokungaphumeleli kokuphefumla lufuna i-ventilator

Umsebenzi wemiphunga wezigulane ezineCOPD uya kuncipha ngokuthe ngcembe ngokuhamba kwexesha.I-COPD isenokungabi nazimpawu ekuqaleni, kodwa iya kuba yingozi ngakumbi njengoko ikhula.Ngokuqhelekileyo, iqala iphuhlisa ukuthayipha i-1 yokungaphumeleli kokuphefumula kunye nohlobo lokungaphumeleli kokuphefumla.Kukho i-hypoxia kuphela, kodwa akukho ngxaki yokugcina i-carbon dioxide.Kweli nqanaba, ingxaki enkulu yesigulana yi-hypoxia, ngoko ke kweli nqanaba, unyango lwe-oksijeni yasekhaya lusetyenziswa kakhulu, nto leyo esiyibiza ngokuba yi-oxygen generator ekhaya.

Xa ukuphuhliswa ukusuka kuhlobo lwe-1 ukuya kuhlobo lwe-2 yokungaphumeleli kokuphefumula, isigulane asiyi kubandezeleka kuphela kwi-hypoxia kodwa kunye nokugcinwa kwe-carbon dioxide.Oku kungenxa yokuba iindlela zomoya ezincinci ziba ngakumbi kwaye zivaliwe ngophuhliso, kwaye umthamo wokutshintshiselana ngegesi uyancipha ngakumbi.Ukugqithisa i-carbon dioxide kunzima ukuyikhupha emzimbeni, kwaye kuya kubangela ukugcinwa kwe-carbon dioxide kwixesha elide.Kweli nqanaba, unyango lwe-ventilator luyafuneka.

Indlela yokugweba ukuba kukugcinwa kwekharbon diokside

Indlela efanelekileyo yokugcina i-carbon dioxide kukuya esibhedlele ukwenza uhlalutyo lwe-arterial blood gas analysis.Ngokusebenzisa uhlalutyo lwegesi yegazi, unokwazi uxinzelelo lweoksijini, uxinzelelo lwekharbhon diokside kunye nezinye izikhombisi.Ngokuqhelekileyo, uxinzelelo lwekharbon diokside ludlula ama-45 ukuba lungaqhelekanga.

Ngaba i-ventilator iyayinciphisa njani ingxaki yokugcinwa kwekharbhon diokside

I-ventilator ibonelela ngokuqhubekayo ngoxinzelelo olulungileyo lomoya wokuphefumla kwindlela yomoya yesigulana ukunyusa umoya wesigulana kunye nokutshintshana ngokugudileyo kwegesi yesigulana.Ngenxa yokuba i-airway encinci ayicacanga, isigulane sesifo se-pulmonary obstructive esingapheliyo sine-oksijini engafanelekanga kuphela kwisigaba sokuqala kwaye siphuhlisela kwinqanaba elilandelayo.Ayisiyiyo kuphela i-oxygenation ehlwempuzekileyo, kodwa ikhokelela ekunciphiseni ngakumbi kwi-ventilation.Ukuncipha kwe-ventilation akuyi kwandisa kuphela ingxaki ye-hypoxia, kodwa kukhokelela ekutshintshisweni kwegesi embi kwaye kunzima ukukhupha igesi ephumayo emzimbeni.

Umsebenzi we-ventilator kukunyusa umoya wesigulane.Ithuba lokuphefumla liyakwandisa uxinzelelo xa isigulane siphefumla, kunceda isigulane ukuba siphefumle igesi eninzi.Xa uphefumla, ithuba lokuphefumula linciphisa uxinzelelo kwaye lisebenzise ukuhlukana koxinzelelo phakathi kwemiphunga kunye nangaphandle ukunceda Isigulane sikhupha igesi ephumayo emzimbeni, ukwenzela ukuba izinga lokuphefumla linyuke, ukwenzela ukuba i-carbon dioxide eninzi ayiyi kuqokelela emzimbeni. .Lo ngumgaqo-siseko wokuba i-ventilator inceda isigulane ukunciphisa umngcipheko wokugcinwa kwe-carbon dioxide.

I-ventilator ayikwazi ukunciphisa kuphela i-carbon dioxide yesigulane i-partial pressure, kodwa iphinde iphucule i-oxygen yesigulane.Xa isigulane sikwixesha lokungaphumeleli kokuphefumula kwe-II, akukhuthazwa ukuba izinga lokuhamba lidlule i-2L / min kunyango lwe-oxygen ngokubanzi, ngenxa yokuba amandla omoya wesigulane ngeli nqanaba alilungile, ukuphefumla ioksijini eninzi kuya kwandisa umngcipheko. ukugcinwa kwekharbon diokside, kunjalo kweli nqanaba.Ukuphefumla okuphantsi kweoksijini, ukuphefumla okuphantsi kweoksijini akulunganga ekuphuculeni ukuhlanganiswa kweoksijini.Ke ngoko, kweli nqanaba, kuyacetyiswa ngokubanzi ukonyusa ukuhamba kweoksijini ngelixa usebenzisa i-ventilator.Kunconywa ukuba uthenge i-oxygen generator engekho ngaphantsi kwe-5L yokusetyenziswa kwentsapho ye-oxygen generator.Xa usebenzisa i-ventilator edibene ne-oxygen generator, kuba i-ventilator inyusa umoya kwaye i-ventilator iyancipha inxalenye ye-oxygen concentration, i-high-flow oxygen inhalation ayibangeli umngcipheko wokugcinwa kwe-carbon dioxide.

Emva kovavanyo oluninzi lolawulo lwedatha, iGuangzhou Hepuler Ventilator R&D Centre iqinisekisile ukuba unyango lwe-ventilator yasekhaya inokunciphisa umthwalo wokuphefumla wezigulana, ukunciphisa inani lokulaliswa esibhedlele ngenxa yohlaselo oluqatha, kunye nokuphucula umgangatho wobomi bezigulana zeCOPD.

Umsebenzi oqhubekayo wevolumu kwi-8-series ventilator ephuhliswe yi-Hepuler inokumisela umthamo ojoliswe kuyo ukuze izigulane ezineCOPD zihlale zigcina umoya wokungena kwemizuzu eyaneleyo ukuhlangabezana neemfuno zokutshintshiselana kwegesi yezigulane ixesha elide kunye nokuphucula i-carbon dioxide.Ukugcinwa, njl.
