Ngaba kufuneka sifunde 'ngoxinzelelo lwe-Perfusion', kungekhona nje uxinzelelo lwegazi esiluvayo emizimbeni yethu?

Mhlawumbi ukhe weva 'ngoxinzelelo lwegazi', akunjalo? Kodwa namhlanje siza kuthetha ngento ebaluleke ngokulinganayo, kodwa mhlawumbi awukayiva kangako ngayo. Yiyo leyo 'Uxinzelelo lwePerfusion'. Ngamafutshane, olu luxinzelelo olufunekayo ukuze igazi lipompelwe kakuhle kwiindawo ezahlukeneyo zomzimba wethu. Kuphela xa olu xinzelelo lulungile apho amalungu ethu anokufumana ioksijini kunye nezondlo azidingayo.

Yintoni 'uxinzelelo lwePerfusion'? Masiyiqonde ngokulula.

Khawucinge nje, ukuze unkcenkceshele izityalo ezikwigadi yakho, kufuneka kubekho uxinzelelo oluhle kumbhobho ovela kwimpompo yamanzi, akunjalo? Ngokufanayo, ukuze amalungu abalulekileyo emzimbeni wethu, intliziyo, ingqondo, izintso, zonke ezi zinto, afumane ioksijini kunye nezondlo ngegazi, olu hlobo lubizwa ngokuba 'luxinzelelo lokuphalaza igazi' kufuneka lube khona. Kalula nje, 'uxinzelelo lokuphalaza igazi' luxinzelelo olufunekayo ukubonelela ngegazi kwizicubu okanye kwilungu. Logama nje olu xinzelelo lukwinqanaba elaneleyo, elo lungu liya kufumana isixa segazi esifunekayo. Yiyo loo nto le yinxalenye ebaluleke kakhulu kwinkqubo yethu yokujikeleza kwegazi. Khawucinge nje, kwenzeka ntoni ukuba olu xinzelelo luyehla kwezinye iindawo? Kulapho kuvela khona iingxaki ezinkulu. Olu nciphiso loxinzelelo lunokuba yingozi, ngakumbi entliziyweni nasebuchotsheni bethu. Kuba ukuba la malungu awafumani igazi ngokufanelekileyo, kunokukhokelela kwiimeko ezinzulu, ngamanye amaxesha ezisongela ubomi.

Isebenza njani le 'pressure perfusion'?

Intliziyo yethu ifana nempompo. Isebenza ngokuqhubekayo, akunjalo? Ngalo lonke ixesha intliziyo yethu ibetha, ikhupha igazi elincinci entliziyweni ize ilithumele kwimithambo yegazi (imithambo yegazi) emzimbeni wethu wonke. Emva koko eli gazi lihamba ukusuka kwimithambo yegazi ukuya kwimithambo yegazi. Kulapho ioksijini egazini itshintshiselana khona neeseli zomzimba wethu. Xa loo msebenzi ugqityiwe, igazi kwimithambo yegazi libuyela entliziyweni ngemithambo yegazi. Lo mjikelo wenzeka rhoqo ngomzuzwana intliziyo ibetha ngawo. Ngoko ke ukuze le nkqubo isebenze kakuhle, oko kubizwa ngokuba 'yi-perfusion pressure' kubalulekile.

Uyazi njani ukuba le 'perfusion' ihamba kakuhle?

Uvavanyo lokuphalaza igazi olungabandakanyi amalungu omzimba angaphakathi emzimbeni ludla ngokuqala ngesixhobo esibizwa ngokuba yi-pulse oximeter. Mhlawumbi sele ukhe wayibona, ngamanye amaxesha ubeka isixhobo esifana ne-clip emnweni wakho ukujonga i-oksijini egazini lakho. Yiyo loo nto. Ithumela ukukhanya okubomvu nokukhanyayo eluswini lwakho. Imolekyuli esegazini lethu ebizwa ngokuba yi-hemoglobin ithwala i-oksijini. Le hemoglobin ifunxa ukukhanya ngendlela eyahlukileyo xa ithwele i-oksijini naxa ingenayo. Isebenzisa loo mahluko, i-pulse oximeter inokubala ukuba ingakanani i-oksijini egazini lakho kwaye ingaba igazi lifika kwindawo ethile ngokufanelekileyo na. Ezinye zezi pulse oximeters zifana ne-clip oyibeka emnweni wakho. Ezinye ziza ne-sensor oyincamathisela emnweni wakho okanye kwenye indawo, njengesitikha. Ngamanye amaxesha oku kunokunamatheliswa kwi-earlobe okanye ebunzini.

Ngoko ke yintoni le 'Perfusion Index'?

I-Perfusion Index (PI) yindlela yokulinganisa ukuba igazi lijikeleza kakuhle kangakanani kwindawo ethile yomzimba wakho. Ilinganisa ubungakanani begazi elineoksijini kuloo ndawo xa kuthelekiswa nobungakanani begazi elingenaoksijini. Amandla afanayo e-pulse oximeter okulinganisa ubungakanani beoksijini egazini akwanceda kwi-Perfusion Index. Ngokulinganisa ukuba ingakanani ioksijini ethwalwa yi-hemoglobin, kunokwenzeka ukulinganisa ukuba ingakanani igazi elitsha (oko kukuthi igazi elisenayo ioksijini) elihamba kuloo ndawo. I-Peripheral Perfusion Index yindlela esebenzisa lo mgaqo ukunceda oogqirha bavavanye kwaye banyange umntu ogulayo. Ixabiso eliphantsi lithetha ukuba intliziyo yakho ayipompi igazi elaneleyo, okanye kukho into ethintela igazi ukuba lihambe ngokufanelekileyo kwiindawo zomzimba wakho ezikude nentliziyo yakho (njengeengalo nemilenze yakho).

Yintoni umahluko phakathi kwe-'Perfusion Index' kunye ne-'Blood Pressure'?

Zombini ezi ndlela zokulinganisa indlela esebenza kakuhle ngayo inkqubo yethu yokujikeleza kwegazi. Kodwa iindlela zahlukile, kwaye azilingani.

• Isalathisi sokuPhefumla: Esi sisilinganiselo sokuba lingakanani igazi elihamba kwindawo ethile. Ixabiso eliphezulu libonisa ukuhamba kwegazi okungcono. Ixabiso eliphantsi lisenokubonisa ingxaki entliziyweni yakho okanye kwimithambo yegazi .
• Uxinzelelo lwegazi: Oku kulinganisa uxinzelelo olungaphakathi kwemithambo yegazi yakho, olulinganiswa ngeemilimitha ze-mercury (mm/Hg). Kukho ixabiso eliphezulu nelisezantsi. Ixabiso eliphezulu (`uxinzelelo lweSystolic`) luxinzelelo olukwimithambo yegazi ngalo lonke ixesha intliziyo ibetha. Ixabiso eliphantsi (`uxinzelelo lweDiastolic` ) luxinzelelo olukwimithambo yegazi phakathi kwentliziyo ezimbini.

Kubalulekile: Ekubeni ezi zinto zimbini zilinganisa izinto ezahlukeneyo, awunakucinga ukuba enye ilungile kwaye enye ilungile. Zombini zibalulekile.

Isebenza njani 'uxinzelelo lwegazi' entliziyweni yakho?

Intliziyo yethu sisihlunu esifuna ukusebenza ngokuqhubekayo ubomi bethu bonke. Ukuze yenze umsebenzi wayo ngokufanelekileyo, intliziyo ifuna ukunikezelwa komoya-mpilo rhoqo. Ifumana oku kwimithambo yegazi ekhethekileyo ebizwa ngokuba yimithambo yentliziyo . Khawuthelekelele, intliziyo isebenzisa phakathi kwe-70% kunye ne-80% yeoksijini edlula kule mithambo-luvo! Akukho nalinye ilungu elisebenzisa umoya-mpilo ongako.Uxinzelelo lweCoronary Perfusion (CPP) yilo olugcina igazi lihamba kule mithambo. Ukuba olu xinzelelo luyehla, intliziyo ayifumani igazi neoksijini eyaneleyo. Oku kunokukhokelela kwiingxaki ezisongela ubomi.

Uyifumana njani le nto?

I-pulse oximetry ayisetyenziselwa ukulinganisa uxinzelelo lwe-coronary perfusion (CPP). Ukulinganisa oku, oogqirha bathatha ezinye iindlela ezimbini zokulinganisa baze bazisebenzise ukubala uxinzelelo lwe-coronary perfusion. Ezi ndlela zokulinganisa zinokuthathwa nge -echocardiography (ukuskena kwentliziyo) okanye nge -catheterization yentliziyo ( uvavanyo apho kufakwa khona umbhobho omncinci entliziyweni). Ezi ndlela zimbini zokulinganisa zezi: 1. Uxinzelelo lwe-Aortic Diastolic: Olu luxinzelelo kwi-aorta yakho (umthambo wegazi omkhulu othwala igazi ukusuka entliziyweni ukuya kuwo wonke umzimba) phakathi kokubetha kwentliziyo. Oku kufunyanwa ngokulinganisa 'uxinzelelo lwegazi' lwakho oluqhelekileyo. Eli linani elisezantsi (`uxinzelelo lwe-Diastolic`) loxinzelelo lwakho lwegazi . 2. 'Uxinzelelo lwe-Left Ventricular End-Diastolic' (LVEDP): Olu luxinzelelo ngaphakathi kwe-ventricle yasekhohlo, enye yamagumbi amabini asezantsi entliziyo, phakathi kokubetha kwentliziyo ezimbini. Ngoku olu 'xinzelelo lokuphalaza igazi entliziyweni' (CPP) lufumaneka ngolu hlobo lulandelayo: 'Uxinzelelo lwe-Aortic Diastolic' - 'Uxinzelelo lwe-Left Ventricular End-Diastolic Pressure' = 'Uxinzelelo lwe-Coronary Perfusion'

Ngoko ke olu 'xinzelelo lokuphefumla' luyichaphazela njani ingqondo?

Emva kwentliziyo, elinye ilungu elibalulekileyo elifuna ioksijini yingqondo yethu. Uxinzelelo lweCerebral Perfusion (CPP) luqinisekisa ukuba igazi lihamba kakuhle kuzo zonke iindawo zengqondo. Ukuba ingqondo ayifumani gazi laneleyo, ungalahlekelwa zingqondo kwimizuzwana embalwa. Yiyo loo nto ibaluleke kakhulu.

Uyifumana njani le nto?

Kufuneka uvavanyo olubini ukuze kubalwe 'uxinzelelo lwe-cerebral perfusion' (CPP) yobuchopho. 1. Uxinzelelo lwegazi: Okokuqala, kulinganiswa 'uxinzelelo lwegazi'. Emva koko, oogqirha babale 'uxinzelelo lwe-Arterial' (MAP) . Le MAP luxinzelelo oluqhelekileyo kwimithambo yakho ngexesha lomjikelo omnye wentliziyo (ixesha eliphakathi kokuba intliziyo yakho iqine kwaye iphumle). Le MAP ibalwa ngolu hlobo lulandelayo:

• Phinda-phinda inani elisezantsi 'loxinzelelo lwegazi' lakho (uxinzelelo lwe-'Diastolic') kabini.
• Yongeza ixabiso elingentla (`uxinzelelo lweSystolic`) kwimpendulo oyifumanayo.
• Zidibanise zonke uze wahlule ixabiso eliphumayo ngo-3. (MAP = [I-Systolic BP + (2 x I-Diastolic BP)] / 3)

2. Uxinzelelo lwe-Intracranial (ICP): I-Intracranial ithetha "ngaphakathi kwekhaka." Phakathi kwengqondo yethu nethambo lekhaka kukho ulwelo lwe-cerebrospinal (CSF).Kukho ulwelo olubizwa ngokuba luxinzelelo lwe-intracranial. Le ICP luxinzelelo olupheleleyo ngaphakathi kwekhakayi olubangelwa yingqondo yakho, igazi elikuyo, kunye nolwelo lwe-CSF. Kukho iindlela ezikhethekileyo zokulinganisa oku, kwaye ngamanye amaxesha kufuneka ufake isixhobo esibuthathaka kwikhakayi. Ngoku, 'uxinzelelo lwe-cerebral perfusion' (CPP) lufumaneka ngolu hlobo: 'Uxinzelelo oluPhakathi lwe-Arterial' (MAP) - 'Uxinzelelo lwe-Intracranial' (ICP) = 'Uxinzelelo lwe-cerebral perfusion' (CPP)

Ziziphi iimeko zonyango eziqhelekileyo ezibangelwa ziingxaki ezinxulumene 'noxinzelelo lwegazi'?

Ingxaki ephambili eyenzeka xa kungekho 'uxinzelelo lokuhamba kwegazi' olwaneleyo naphi na emzimbeni wakho ibizwa ngokuba yi -'ischemia' . Oku kuthetha ukuba indawo ayifumani igazi elaneleyo, ngoko ke ayifumani ioksijini nezakhamzimba ezaneleyo. Ukuba le 'ischemia' iyenzeka engalweni okanye emlenzeni, izicwili ezikuloo ndawo zinokuqala ukufa. Oku kunokukhokelela kwizinto ezifana 'ne-gangrene' (ukubola kwezicubu) kunye nosulelo. Ukuba oku kuchaphazela ilungu eliphambili, elo lungu lingaqala ukungasebenzi kancinci kancinci, okukhokelela kwiingxaki ezinzulu, nezibulalayo. Nazi ezinye zeemeko ezinokubangelwa okanye ezinxulunyaniswa neengxaki 'zoxinzelelo lokuhamba kwegazi':

• Ukuhlaselwa yintliziyo
• Ukumelwa yintliziyo
• Isifo semithambo yentliziyo
• Istroke
• Ukothuka kwentliziyo
• Ukungabikho koxilongo engqondweni (umonakalo wobuchopho obangelwa kukungabikho komoya-mpilo engqondweni)
• I-atherosclerosis
• Izilonda zemilenze neenyawo
• Isifo sikaRaynaud (ukuncipha kokunikezelwa kwegazi emilenzeni)

Ndingenza ntoni ukuze ndigcine 'uxinzelelo lwam lokuphalaza igazi' lukwinqanaba elikhuselekileyo?

'Uxinzelelo lwakho lokuphefumla', ingakumbi entliziyweni nasengqondweni yakho, alusoloko luyingxaki ngaphandle kokuba unesifo esithile esichaphazela intliziyo yakho kunye nenkqubo yokujikeleza kwegazi. Nangona kunjalo, ungenza ezi zinto ukuthintela okanye ukulibazisa ukuphuhliswa kwezi zifo:

• Gcina ubunzima bakho busempilweni. Akulunganga ukuba mkhulu kakhulu okanye ube mncinane kakhulu.
• Yitya ukutya okunempilo. Yitya ukutya okunamafutha aphantsi, ityuwa, neswekile, kunye nokutya okuneziqhamo nemifuno eninzi.
• Yeka ukusebenzisa iimveliso zecuba (kuquka icuba elingenamsi kunye nokutshaya i-vaping). Ezi zinto zibangela umonakalo omkhulu kwimithambo yegazi.

"Cinga ngayo, indlela yokuphila esempilweni ifana nokugcina imizimba yethu ikwimeko entle. Njengokulungisa imoto ukuze ihlale ikwimeko entle, kufuneka siyinyamekele kakuhle imizimba yethu."

Eyona ndlela ilungileyo yokuchonga naziphi na iingxaki ezinokuthi zichaphazele 'uxinzelelo lwegazi' kukwenza uvavanyo lomzimba rhoqo ngonyaka.Oku kukwabizwa ngokuba 'kukuhlolwa kwempilo'. Ngovavanyo olulula olwenziwe kugqirha wakho, unokubona iingxaki ezinkulu ngaphambi kokuba ubonise iimpawu. Ukuba uzibamba kwangethuba, ungafumana unyango kwaye uyeke umonakalo osisigxina okanye unciphise impembelelo yazo.
