Izinhlelo ezikhethekile zokuqeqesha ukuphefumula zavela ngaphambi kwesikhathi sethu eChina yasendulo, India, Greece. Njengamanje, ukuvocavoca okuphefumula kubhekwa njengesinye sezici eziqine kakhulu zokuthola umzimba. Amakhulu amasu ahlukahlukene alezi zokuvocavoca asetshenzisiwe, okuvumela umuntu ukuba aqeqeshe izici ezithile zesimiso sokuphefumula futhi, ngenxa yalokho, ukwandisa amandla okugcina amagciwane. Amasu okuthuthuka anjalo avumela ukuqinisa imisipha yokuphefumula yesifuba nesifo somzimba, ukuthuthukisa umsebenzi wezitho zangaphakathi ezisemgodini wesisu, ubuyekeze uhlelo lokuphefumula nesimo senhliziyo. Ngaphezu kwalokho, ngosizo lokuzivocavoca kokuzilibazisa ungathonya ukuzwakalisa isimiso sezinzwa zomphakathi. Omunye wemisebenzi ebaluleke kakhulu yokuthuthukisa ukuvocavoca okuphefumula ukukhulisa ukugcinwa kokunikezela umzimba nge-oxygen. Ukuqeqeshwa okuqhubekayo kunomthelela ekwenzeni ukuthi izicubu zithatha oksijini okwedlulele egazini, kuyilapho umsebenzi wezinqubo zokuphefumula nezokujikeleza uba ukonga ngokwengeziwe.
Isisekelo se-air conditioning ye-apparatus yokuphefumula ukulawula okunenhloso yemisipha, enikeza inqubo yokuphefumulelwa nokuphelelwa yisikhathi. Izinkinga ezinkulu kulokhu zenzeka ngenqubo yokuqapha ukunyakaza kwe-diaphragm. Ngosizo lokulawulwa okulawulwayo kwemisipha yokuphefumula ngesikhathi sokuqeqesha okukhethekile, lo muntu uqala ukuphefumula okwesithathu, okuhlanganisa izigaba ezilandelayo: 1) ukuphuma kwamanzi; 2) isikhashana; 3) ukuxhuma. Isigaba sokuqala senziwa ngendwangu yomzimba ngokuphumula okuphelele komzimba wokuphefumula wesifuba nesifo se-diaphragm. Kulesi simo, ukuphefumula akufanele kwenziwe nakancane. Isigaba sesibili singenye yezakhi ezibaluleke kakhulu ekuthuthukiseni impilo-gymnastics yokuphefumula. Ikhefu kufanele libe lemvelo futhi limnandi. Isigaba sesithathu senziwa ngokuzenzekelayo ngekhala, cishe kungenasici. Kulabo abafisa ukuhlanganyela ekuzivocavoca okuphefumulayo, kubalulekile ukuthi ukwazi ukugxila ekunakekeleni kwakho. Ngokuphefumula okufanelekile, amahlombe kufanele aguquguquke, ngokuphefumulelwa imigqa engezansi yezimbambo ihamba eceleni, futhi umthamo we-thorax ukwanda.
Ukuqeqeshwa kwe-gas exchange of the body kusho, ngaphezu kwakho konke, inqubo yokulawulwa kokuziphendulela kweminyango yokuphefumula. Ngaphezu kwalokho, ukuqeqesha okunjalo kungenzeka ukusebenzisa indlela enjengokuphefumulela nge-tube yobubanzi obuthile futhi ubude obuguquguqukayo, okwenza kube lula ukudala isikhala "esengeziwe" esengeziwe. Lapho inqubo yokuphefumula iqhutshwa ngaleyo bhubhu, umoya owangena emaphashini (okuhlushwa okwe-oxygen ka-21%) uhlanjululwa yi-air residual emaphashini nangomoya wendawo "efile" (ene-oxygen content of about 15%). Ngakho-ke, ukuhlushwa kwe-oxygen ku-alveoli kunciphisa, futhi okuqukethwe kwe-carbon dioxide kwanda. Izinguquko ezinjalo ziye zaveza umphumela wokuqeqeshwa ohlelweni lokuphefumula lomzimba. Ukufeza ukuqeqeshwa okunjalo kuyadingeka ukuthenga izilimo eziyizigaxa ezimbili ezifakwe phakathi komunye nomunye, ubude obuphelele obungashintshwa ngokuzenzakalelayo ngokuthanda (umthamo wendawo "efile" nayo iyashintsha). Ukuzivocavoca kokuzivocavoca okuphefumula nokusetshenziswa kwalokhu kusebenza kufanele kwenziwe ngenkathi uhlezi, kanti ubude bokuqala bhubhu kufanele bukhethwe ngendlela yokuthi lapho ukuphefumula kungabangeli ubunzima obuningi. Ukuphefumula ngokusebenzisa i-tube oyidinga kalula futhi ngaphandle kokuphazamiseka, ngaphandle kokwenza noma yimiphi imizamo enamandla. Okokuqala, isikhathi sokuqeqesha ekuzivocavoca okuphefumula akufanele sidlule imizuzu emihlanu, futhi inani lokuphindaphinda le nqubo ngosuku ngalunye akufanele libe ngaphezu kwamabili. Nsuku zonke ukwandisa isikhathi sokuqeqesha imizuzu engu-1 - 2 futhi kancane kancane ukwandisa ubude bhubhu (okungukuthi, ukwandisa umthamo wendawo "efile"), emva kwezinyanga ezintathu, isikhathi sokuzivocavoca kufanele senyuke sibe imizuzu engama-30. Kumele wengezwe ukuthi ukuqeqeshwa kwezempilo kwesimiso sokuphefumula nge-tube kuyindlela elula, kodwa ephumelelayo futhi ephephile yokuthuthukisa isimo jikelele somzimba. Ukuzivocavoca okunjalo kungenziwa ekhaya. Kodwa-ke, kuyadingeka ukuba uqaphe njalo isimo sezempilo. Uma kunenkinga ekwenzeni ukunyakaza kokuphefumula, ukuqeqeshwa kumele kumiswe kuze kube yilapho ukuphefumula okuvamile kuvuswa, bese ubude bhubhu busetshenziswa kancane.
Ngaphandle komthelela wokuphulukisa, ukuvivinya umzimba kusiza umuntu ukwakha isichazamazwi esihle. Ukuphefumula kwesigaba esithathu esifanele esakhiwe ngesikhathi sokuqeqesha ngokugxila ekuthuthukiseni idokhumenti kudinga ukugxila okukhethekile ekufaneni nasekupheleni kwesikhathi sokuphumula.
Ngakho-ke, ngosizo lokuqeqeshwa okhethekile ekuzivocavoca kwempilo yokuphefumula, kungenzeka ukwandisa kakhulu amandla omzimba womuntu ukusebenzisa igazi le-oxygen. Lokhu kuzokwenyusa ukwanda kwamandla omzimba womzimba futhi kuzokwenza ukwanda komthamo wokusebenza, ukuvumelanisa nemithwalo yemvelo, ukwakheka kwenhlalakahle nokujabula usuku lonke.
