Ukudlula kweCardiopulmonary kuyindlela esetshenziswa kakhulu ekuhlinzeni inhliziyo okuvulekile, njengokufaka esikhundleni se-valve, ukufakelwa kabusha noma ukuvuselelwa kwemisipha yenhliziyo, njengoba ingena esikhundleni somsebenzi wenhliziyo namaphaphu. Ngakho-ke, udokotela uyakwazi ukuhlinza ngaphandle kokukhathazeka ngokujikeleza kwegazi.

Ngaphezu kwalokho, le ndlela futhi ivimbela ukudlula kwegazi lidlule emaphashini, elehlisa amathuba okuba nesifo sokuvuvukala kwamaphaphu, njengoba ingekho ingozi yokuhlukumezeka enhliziyweni okubangela amahlule agcina ethuthelwe emaphashini.

Isebenza kanjani

Ukudlula kweCardiopulmonary kwenziwa isethi yemishini ezama ukufaka esikhundleni nokulingisa ukusebenza kwegazi emzimbeni. Ngakho-ke, kuyindlela efaka izinyathelo nezakhi eziningana:

1. Ukususwa kwegazi eliyingozi: i-catheter ibekwa eduze kwenhliziyo ukuze kususwe igazi eliyingozi elivela emzimbeni wonke, liyivimbele ekufinyeleleni endaweni efanele yenhliziyo;
2. Isiziba: igazi elisusiwe linqwabelene echibini elingaba amasentimitha angama-50 kuye kwangama-70 ngaphansi kwezinga lenhliziyo, eligcina ukugeleza okuqhubekayo ngomshini futhi okuvumela udokotela ukuthi engeze imithi noma ukumpontshelwa igazi ekusakazeni kwegazi;
3. Ioksijini: lapho-ke, igazi lithunyelwa entweni ebizwa nge-oxygenator, esusa i-carbon dioxide eyeqile egazini le-venous bese ingeza i-oxygen ukuyenza ibe yimithambo yegazi;
4. Isilawuli sethempelesha: ngemuva kokushiya i-oxygenator, igazi liya kumlawuli wokushisa, okuvumela udokotela ukuba alondoloze izinga lokushisa elilingana nelomzimba noma alinciphise, lapho edinga ukudala ukuboshwa kwenhliziyo, isibonelo;
5. Pump kanye lemifanekiso: ngaphambi kokubuyela emzimbeni, igazi lidlula empompini obuyisela amandla enhliziyo, liphusha igazi ngesihlungi esisusa amahlule namanye amagesi okungenzeka ukuthi akhe ngesikhathi sokujikeleza ngaphandle komzimba;
6. Ama-Microfilters: ngemuva kwesihlungi, kukhona nesethi yama-microfilters asusa izinhlayiya ezincane, okuthi, noma zingabangeli izinkinga ekusakazeni komzimba, zikwazi ukudlula kwisithiyo segazi nobuchopho futhi zifinyelele ebuchosheni;
7. Ukubuyiselwa kwegazi lomzimba emzimbeni: ekugcineni, igazi lingena kabusha emzimbeni, ngqo ku-aorta, lisatshalaliswa emzimbeni wonke.

Kuyo yonke le nqubo, kunamaphampu amaningi asiza igazi ukuba ligijime, ukuze lingami futhi lenyuse ubungozi bamahlule.

Izinkinga ezingenzeka

Yize kuyindlela esetshenziswa kabanzi, elula futhi enezinzuzo eziningi zokuhlinzwa kwenhliziyo, ukudlula kwe-cardiopulmonary kungadala ezinye izinkinga. Enye yezinkinga ezivame kakhulu ukuthuthukiswa kokuvuvukala okuhlelekile, lapho umzimba uphendula ngamaseli egazi ukulwa nesifo. Lokhu kungenxa yokuthi igazi lihlangana nezindawo ezingezona ezemvelo ngaphakathi komshini, ezigcina zibhubhise amangqamuzana egazi amaningana futhi zidale impendulo yokuvuvukala emzimbeni.

Ngaphezu kwalokho, ngenxa yezinguquko ezisejubaneni nasezingeni lokushisa igazi elingadlula kule divayisi, futhi kwandisa ubungozi bamahlule futhi, ngakho-ke, ngemuva kwalolu hlobo lokuhlinzwa kubaluleke kakhulu ukwazi ukubonakala kokuhlanganiswa komzimba lung noma isifo sohlangothi. Kodwa-ke, njengoba kufanele uhlale e-ICU ngemuva kokuhlinzwa, imvamisa zonke izimpawu ezibalulekile ziyaqashwa ukugwema lolu hlobo lwezinkinga.
