Yintoni ukudlula kwentliziyo kunye nendlela esebenza ngayo

• Iingxaki ezinokwenzeka

Ukudlula kwiCardiopulmonary yindlela esetyenziswa kakhulu kutyando lwentliziyo oluvulekileyo, njengokutshintsha kwevalve, ukufakelwa ngokutsha okanye ukuvuselelwa kwemisipha yentliziyo, njengoko ithatha indawo yentliziyo nemiphunga. Ke, ugqirha uyakwazi ukwenza utyando ngaphandle kokukhathazeka ngokuhamba kwegazi.

Ukongeza, obu buchule buthintela ukuhamba kwegazi emiphungeni, nto leyo enciphisa amathuba okuba imbumba yemiphunga ibekho, kuba akukho bungozi bokuba nomothuko entliziyweni obangela amahlwili agcina ethunyelwe emiphungeni.

Ingaba isebenza kanjani

Ukudlula kwiCardiopulmonary kwenziwa ngoseto loomatshini abazama ukubuyisela kwaye baxelise ukusebenza kwegazi emzimbeni. Ke, bubuchule obubandakanya amanyathelo kunye nezinto ezithile:

1. Ukususwa kwegazi elinobuhlungu: i-catheter ibekwe kufutshane nentliziyo ukuze isuse igazi elinemithambo-luvo eliphuma emzimbeni uphela, ukuyithintela ukuba ingafiki kwindawo elungileyo yentliziyo;
2. Idama: igazi elisusiweyo liqokelelwe kwidama malunga ne-50 ukuya kwi-70 cm engaphantsi kwenqanaba lentliziyo, eligcina ukuhamba okuqhubekayo ngomatshini kwaye kusavumela ugqirha ukuba ongeze amayeza okanye utofelo-gazi ekujikelezeni kwegazi;
3. Ioksijini: emva koko, igazi lithunyelwa kwisixhobo esibizwa ngokuba yioksijini, esisusa ikharbon diokside engaphezulu kwigazi elinemithambo kwaye songeza ioksijini ukuyenza ibe ligazi lomthambo;
4. Umlawuli wobushushu: emva kokushiya ioksijini, igazi liya kumlawuli wobushushu, ovumela ugqirha ukuba agcine iqondo lobushushu elilingana nelomzimba okanye alinciphise, xa kufuneka abangele ukubanjwa kwentliziyo, umzekelo;
5. Impompo kunye lokucoca ulwelo: ngaphambi kokubuyela emzimbeni, igazi lidlula kwimpompo ethatha indawo yokomelela kwentliziyo, lityhale igazi ngesihluzo esisusa amahlwili kunye nezinye iigesi ezinokuthi zibekho ngexesha lokuhamba ngaphandle komzimba;
6. Iifayile ezincinci: emva kokucoca ulwelo, kukwakhona neseti yee-microfilters ezisusa amasuntswana amancinci, athi, nangona engabangeli ngxaki ekujikelezeni komzimba, angadlula kwisithintelo segazi-sobuchopho kwaye afikelele kwingqondo;
7. Ukubuyela kwegazi emzimbeni: Ekugqibeleni, igazi liphinda lingene emzimbeni, ngqo kwi-aorta, lihanjiswa emzimbeni wonke.

Kuyo yonke le nkqubo, kukho iimpompo ezininzi ezinceda igazi ukuba lijikeleze, ukuze lingami kwaye lenyuse umngcipheko wamahlwili.

Iingxaki ezinokwenzeka

Nangona iyindlela esetyenziswa ngokubanzi, ilula kwaye inezibonelelo ezininzi zotyando lwentliziyo, ukudlula kwentliziyo kunokubangela iingxaki. Olunye lweengxaki eziqhelekileyo kukukhula kokudumba kwenkqubo, apho umzimba uphendula ngeeseli zegazi ukulwa usulelo. Kungenxa yokuba igazi lidibana nezinto ezingezozamvelo ngaphakathi kumatshini, ezigcina zitshabalalise iiseli zegazi ezininzi kwaye zibangele impendulo yomzimba emzimbeni.

Ukongeza, ngenxa yotshintsho kwisantya kunye neqondo lobushushu elinokuthi igazi lidlule lingene kwisixhobo, sonyusa umngcipheko wamahlwili kwaye, ke ngoko, emva kolu hlobo lotyando kubaluleke kakhulu ukuba sazi ngokubonakala kweembumba. umphunga okanye ukubetha. Nangona kunjalo, kuba kuya kufuneka uhlale kwi-ICU emva kotyando, ngesiqhelo zonke iimpawu ezibalulekileyo ziyajongwa ukunqanda olu hlobo lweengxaki.
