Njengesinye sezifo ezine ezingamahlalakhona ezinezinga eliphezulu lokufa kwabantu, isifo se-chronic obstructive pulmonary sikhula kancane kancane sisuka komnene siye kobunzima.Lapho isifo siqhubekela ezingeni elithile, kuyadingeka ukusebenzisa ai-ventilator engangenisiukusiza ukungena komoya, kodwa indlela yokulinganisa leli zinga

Ukwehluleka kokuphefumula kohlobo lwe-II kudinga i-ventilator

Umsebenzi wamaphaphu weziguli ezine-COPD uzokwehla kancane kancane ngokuhamba kwesikhathi.I-COPD ingase ingabi nazimpawu ekuqaleni, kodwa izoba yingozi kakhulu njengoba ikhula.Imvamisa, iqala ukukhula ngohlobo 1 lokuhluleka kokuphefumula bese ithayipha ukwehluleka ukuphefumula koku-1.Kukhona i-hypoxia kuphela, kodwa ayikho inkinga yokugcina i-carbon dioxide.Kulesi sigaba, inkinga enkulu yesiguli i-hypoxia, ngakho-ke kulesi sigaba, ukwelapha komoya-mpilo wasekhaya kusetshenziswa ikakhulukazi, okuyilokho esivame ukukubiza ngokuthi i-generator oxygen yasekhaya.

Lapho sithuthuka kusuka kuhlobo 1 kuya kohlobo 2 ukwehluleka ukuphefumula, isiguli ngeke nje sihlupheke ngenxa ye-hypoxia kodwa futhi nokugcinwa kwe-carbon dioxide.Lokhu kungenxa yokuthi imigudu yomoya emincane iya ngokuya ivinjelwa ngokuthuthuka, futhi umthamo wokushintshanisa igesi uyancipha ngokwengeziwe.I-carbon dioxide eyengeziwe kunzima ukuyikhipha emzimbeni, futhi izobangela ukugcinwa kwe-carbon dioxide ngokuhamba kwesikhathi.Kulesi sigaba, ukwelashwa kwe-ventilator kuyadingeka.

Indlela yokwahlulela ukuthi ukugcinwa kwe-carbon dioxide

Indlela engcono kakhulu yokugcinwa kwe-carbon dioxide ukuya esibhedlela ukuyohlola i-arterial blood gas.Ngokuhlaziya i-arterial blood gas, ungakwazi ukwazi i-oxygen partial pressure, carbon dioxide partial pressure nezinye izinkomba.Ngokuvamile, i-carbon dioxide partial pressure idlula ama-45 ukuze ibe engavamile.

I-ventilator iyinciphisa kanjani inkinga yokugcinwa kwe-carbon dioxide

I-ventilator inikeza umoya ocindezelayo oqhubekayo wokuphefumula ngendlela yesiguli ukuze kwandiswe umoya omncane wesiguli futhi ibone ukushintshana okushelelayo kwegesi yesiguli.Ngenxa yokuthi umzila omncane wokuphefumula awucacile, isiguli sesifo se-obstructive pulmonary esingapheli singenawo umoya-mpilo kahle ekuqaleni kwesigaba sokuqala futhi sithuthukela esigabeni sakamuva.Akukhona nje kuphela ukuthi i-oxygenation impofu, kodwa futhi iholela ekwehleni okuqhubekayo kokungena komoya.Ukuncipha kokungena komoya ngeke nje kukhulise inkinga ye-hypoxia, kodwa futhi kuholele ekushintshisaneni kwegesi okungekuhle futhi kube nzima ukukhipha igesi yokukhipha emzimbeni.

Umsebenzi we-ventilator ukwandisa umoya wesiguli.Ithuba lokuphefumula likhulisa umfutho lapho isiguli sihogela, kusize isiguli ukuba sihogele igesi eningi.Lapho uphefumula, ithuba lokuphefumula linciphisa ingcindezi futhi lisebenzisa umehluko wengcindezi phakathi kwamaphaphu nangaphandle ukusiza Isiguli sikhiphe igesi ephumayo emzimbeni, ukuze izinga lokuphefumula likhuphuke, ukuze i-carbon dioxide eningi ingaqoqiwe emzimbeni. .Lesi isimiso sokuthi umshini wokungenisa umoya usiza isiguli ukunciphisa ingozi yokugcinwa kwe-carbon dioxide.

I-ventilator ayikwazi nje ukunciphisa ukucindezela kwengxenye ye-carbon dioxide yesiguli, kodwa futhi ithuthukise umoya-mpilo wesiguli.Uma isiguli sisesikhathini sokuhluleka kokuphefumula kohlobo lwe-II, akunconywa ukuvumela izinga lokugeleza lidlule i-2L/min ekwelashweni okuvamile kwe-oxygen, ngoba ikhono lokuphefumula lesiguli kulesi sigaba alilungile, ukuhogela umoya-mpilo omningi kuzokwandisa ingozi. ukugcinwa kwe-carbon dioxide, ngakho-ke kulesi sigaba.Ukuhogela komoyampilo okugeleza okuphansi, ukuhogela komoyampilo okugeleza okuphansi akulungile ekuthuthukiseni ukuqiniswa komoyampilo.Ngakho-ke, kulesi sigaba, ngokuvamile kunconywa ukwandisa ukugeleza komoya-mpilo ngenkathi usebenzisa i-ventilator.Kunconywa ukuthi uthenge ijeneretha ye-oxygen engekho ngaphansi kuka-5L ukuze usebenzise umndeni wamajeneretha we-oxygen.Uma usebenzisa i-ventilator ehlanganiswe nejeneretha ye-oxygen, ngenxa yokuthi i-ventilator inyusa umoya futhi i-ventilator ihlanza ingxenye ye-oxygen concentration, ukugeleza okuphezulu kwe-oxygen akudali ingozi yokugcinwa kwe-carbon dioxide.

Ngemuva kokuhlolwa okuningi kokulawulwa kwedatha, i-Guangzhou Hepuler Ventilator R&D Center ikuqinisekisile ukuthi ukwelashwa ngemishini yokuphefumula yasekhaya kunganciphisa umthwalo wokuphefumula weziguli, kunciphise isibalo sokulaliswa esibhedlela ngenxa yokuhlaselwa okunamandla, futhi kuthuthukise izinga lempilo yeziguli ezine-COPD.

Umsebenzi wevolumu oqhubekayo ku-ventilator yochungechunge lwe-8 eyakhiwe yi-Hepuler ingasetha ivolumu ye-tidal ehlosiwe ukuze iziguli ezine-COPD zikwazi njalo ukugcina umoya omncane okwanele ukuhlangabezana nezidingo zokushintshana kwegesi yeziguli isikhathi eside futhi zithuthukise i-carbon dioxide.Ukugcinwa, njll.
