Kutheni ii-ventilators kunye neejenereyitha zeoksijini kufuneka zihambelane neeparamitha zeoksijini yegazi?

Isixhobo sokungenisa umoya sisixhobo esinokuthatha indawo okanye siphucule ukuphefumla komntu, sandise ukuphefumla kwemiphunga, siphucule umsebenzi wokuphefumla, kunye nokunciphisa umsebenzi wokuphefumla.Ngokuqhelekileyo isetyenziselwa izigulane ezinokungaphumeleli kwe-pulmonary okanye ukuphazamiseka kwendlela yomoya engakwazi ukuphefumla ngokuqhelekileyo.I-inhalation kunye nomsebenzi wokuphefumula womzimba womntu unceda isigulane ukuba sigqibe inkqubo yokuphefumla kunye ne-inhalation.

Ijeneretha ye-oksijini ngumatshini okhuselekileyo kunye nolungele ukukhupha i-oxygen ecocekileyo.Yijenereyitha ye-oksijini ecocekileyo, icinezela kwaye ihlambulule umoya ukuvelisa i-oksijini, kwaye emva koko ihlambulule kwaye iyinike isigulane.Ifanelekile kwizifo zenkqubo yokuphefumula, izifo zentliziyo kunye nengqondo.Kwizigulane ezine-vascular disease kunye ne-altitude hypoxia, ngokukodwa ukusombulula iimpawu ze-hypoxia.

Kuyaziwa ukuba uninzi lwabaguli abaswelekileyo abane-Covid-19 inyumoniya banokusilela kwamalungu amaninzi okubangelwa yi-sepsis, kwaye ukubonakaliswa kokusilela kwamalungu amaninzi emiphungeni kukuphefumla okubuhlungu kwesifo se-ARDS, inqanaba lezehlo elisondele kwi-100% .Ke ngoko, unyango lwe-ARDS lunokuthiwa lujoliso kunyango lwenkxaso kwizigulana ezinenyumoniya ye-Covid-19.Ukuba i-ARDS ayiphathwa kakuhle, isigulana sinokusweleka kungekudala.Ngexesha lonyango lwe-ARDS, ukuba i-oxygen saturation yesigulana isephantsi kunye ne-nasal cannula, ugqirha uya kusebenzisa i-ventilator ukunceda isigulana ukuphefumla, okubizwa ngokuba yi-mechanical ventilation.Ukungena komoya ngoomatshini kwahlulwa kwakhona kwaba kukungena komoya okungenelelayo kunye nokungena komoya okuncedayo.Umahluko phakathi kwezi zimbini yi-intubation.

Ngapha koko, ngaphambi kokuqhambuka kwe-Covid-19 pneumonia, "unyango lweoksijini" yayisele ilunyango olubalulekileyo lwe-adjuvant kwizigulana ezinezifo zokuphefumla kunye nentliziyo.Unyango lwe-oksijeni lubhekiselele kunyango lokuphefumla ioksijini ukunyusa amanqanaba e-oksijini yegazi kwaye ifanelekile kuzo zonke izigulane ze-hypoxic.Phakathi kwabo, izifo zenkqubo yokuphefumula kunye nenkqubo ye-cardiovascular system zizifo eziphambili, ngakumbi kunyango lwe-Cronic obstructive pulmonary disease (COPD), unyango lwe-oksijini lusetyenziswe njengonyango olubalulekileyo lwe-adjuvant kwintsapho nakwezinye iindawo.

Ingaba lunyango lwe-ARDS okanye unyango lwe-COPD, zombini ii-ventilators kunye ne-oxygen concentrators ziyafuneka.Ukugqiba ukuba ngaba kuyimfuneko ukusebenzisa i-ventilator yangaphandle ukuncedisa ukuphefumla kwesigulane, kuyimfuneko ukubeka iliso kwi-oxygen saturation yegazi yesigulane ngexesha lenkqubo yonke yonyango ukugqiba umphumo "wonyango lwe-oxygen".

Nangona ukuphefumla ioksijini kuluncedo kumzimba, ingozi yetyhefu yeoksijini ayinakuhoywa.Ubuthi beoksijini bubhekisa kwisifo esibonakaliswa ngotshintsho lwe-pathological ekusebenzeni kunye nesakhiwo seenkqubo ezithile okanye amalungu emva kokuba umzimba uphefumle ioksijini ngaphezulu koxinzelelo oluthile ixesha elithile.Ke ngoko, ixesha lokuphefumla ioksijini kunye noxinzelelo lwe-oxygen yesigulane inokulawulwa ngokubeka iliso kwi-oxygen saturation yegazi ngexesha langempela.
