Ngaba wakha wema wacinga ngendlela igazi elihamba ngayo lisuka entliziyweni yakho liye kuzo zonke iikona zomzimba wakho, lide liye kwiminwe yakho? Kufana nothungelwano lweendlela kwisixeko. Kwezinye iindawo, iimoto zihamba kakuhle, kwezinye iindawo, zixinene, kwaye kwezinye iindawo, iindlela zincinci. Ukuhamba kwegazi ngaphakathi emizimbeni yethu kuyafana. Kwizonyango, oku sikubiza ngokuba kukuhamba kwegazi, amandla akuchaphazelayo, kunye nenkqubo edlula kuyo, 'i-hemodynamics.' Ungakhathazeki, igama lisenokuvakala liyinkimbinkimbi kancinci, kodwa ibali lilula kakhulu. Masithethe ngalo.
Yintoni kanye kanye i-hemodynamics?
Ngamafutshane, i-hemodynamics luphando lwendlela igazi elihamba ngayo kwimithambo yakho yegazi kunye nemithambo kunye namandla ahlukeneyo achaphazela ukuhamba kwegazi.
Ngokwesiqhelo, igazi lihamba kwimithambo yegazi yomntu ophilileyo ngendlela egudileyo nehlelekileyo. Oku sikubiza ngokuba yi-laminar flow . Njengamanzi ahamba ngepayipi, igazi lihamba ngokukhawuleza embindini wemithambo yegazi kuba akukho kungqubana okukhulu neendonga.
Nangona kunjalo, ngaphakathi kwamagumbi asezantsi entliziyo yakho (siwabiza ngokuba zii-ventricles ) kwaye apho imithambo yegazi isasazeka khona, okanye apho umthambo wegazi uncipha ngequbuliso, olu hambo luba lunxunguphalo ngakumbi. Silubiza olu nxunguphalo lokuhamba . Kuhambo olunxunguphalo kangaka, kufuna amandla amaninzi ukutyhala igazi phambili.
Imithambo yegazi emincinci ephuma kwi-aorta yakho ihambisa ioksijini kunye nezondlo kuyo yonke iseli kunye nezicubu zomzimba wakho. Emva kokuthatha ioksijini kwizitho zakho zomzimba, igazi libuyela entliziyweni yakho ngemithambo. Intliziyo emva koko ipompa igazi liye emiphungeni yakho, apho liphinda lithathe ioksijini, kwaye umjikelo uqala kwakhona.
Khawuthelekelele ukuba kukho imiqobo endleleni ukuze eli gazi lihambe.
- Ngamanye amaxesha iidipozithi ze-cholesterol (i-plaque) zenzeka eludongeni lwemithambo yegazi, zenze "ii-speed bumps." Ezi zinciphisa indlela yokuhamba kwegazi. Ngamanye amaxesha ezi dipozithi zinokuqhekeka kwaye zivale ngokupheleleyo imithambo yegazi.
- Kwakhona, ihlwili legazi linokwenza kwaye livale umthambo.
- Okanye mhlawumbi intliziyo yakho ibuthathaka kwaye ayikwazi ukupompa igazi elaneleyo emzimbeni wakho.
Nayiphi na kwezi ngxaki inokuthintela inkqubo yethu yokujikeleza kwegazi ekwenzeni umsebenzi wayo ngokufanelekileyo, oko kuthetha ukuba ayinakukwazi ukuhambisa ioksijini kunye nezondlo ezifunekayo kwiseli nganye emzimbeni.
Kutheni kubaluleke kangaka ukwazi nge-hemodynamics?
Ukuqonda i-hemodynamics kubaluleke kakhulu, kuba ngayo ungafumana ukuqonda okungcono ngesifo sentliziyo okanye imeko yemithambo yegazi.
Umzekelo, khawucinge ukuba une-high blood pressure. Xa ufunda nge-hemodynamics, uyaqonda ukuba xa uxinzelelo lusanda, intliziyo kufuneka isebenze nzima ukupompa igazi. Emva koko, ugqirha uza kukunika iyeza elenza imithambo yegazi ibe banzi (ikhululeke) kwaye lenze indawo engakumbi yokuba igazi lihambe. Emva koko, umthwalo entliziyweni uyancipha, kwaye uxinzelelo luyalawulwa.
Ugqirha wakho usebenzisa idatha ye-hemodynamics ukunceda ekuxilongeni nasekuqikeleleni ikamva lesifo. Umzekelo, banokujonga ukuba ivalvu yentliziyo iyavuza na, nto leyo enokuthintela igazi ukuba lihambe kakuhle. Banokujonga nokuba ukuhamba kwegazi lakho kuye kwaphucuka na emva kotyando okanye amayeza.
I-Hemodynamics ayipheleli nje kuxinzelelo lwegazi. Uxinzelelo yinxalenye enye nje yale nkqubo iyonke. Zininzi nezinye izinto ezichaphazela indlela igazi lethu elihamba ngayo.
Ziziphi izinto ezichaphazela ukuhamba kwegazi?
Kukho izinto ezahlukeneyo ezenza kube lula okanye zithintele ukuhamba kwegazi emizimbeni yethu. Umzimba wethu uhlala utshintsha ezi zinto, uzama ukunika iiseli kanye oko zikudingayo. Makhe sijonge izinto eziphambili.
| I-Factor | Indlela Echaphazela Ngayo |
|---|---|
| Ubungakanani (ububanzi) bemithambo yegazi | Kulula ukuba igazi lihambe ngemithambo yegazi emikhulu nebanzi. Kodwa xa igazi lihamba ngemithambo yegazi encitshiswe yi-cholesterol deposits, kuba nzima kakhulu. |
| Ukungqubana | Xa igazi lihamba, ligudla iindonga zemithambo. Olu ngquzulwano lubangela ukuba igazi lihambe kancinci kufutshane neendonga. Igazi lihamba ngokukhawuleza phakathi kwemithambo. |
| Ukuxinana kwemithambo yegazi kunye nokwandiswa kwayo | Imithambo yethu yegazi inokwanda kwaye inciphe njengoko kufuneka. Le yindlela umzimba olawula ngayo ukuhamba kwegazi kunye noxinzelelo lwegazi. |
| Utshintsho kuxinzelelo | Kukho umahluko phakathi kwamandla entliziyo epompa ngawo igazi kunye nokumelana okunikezelwa yimithambo yegazi. Njengoko uxinzelelo lusanda, intliziyo kufuneka isebenze nzima ngokuchasene nokumelana nalo kumelana. |
| Isiphumo sentliziyo | Eli linani legazi elimpontshwa yintliziyo ngokubetha kanye. Xa uzilolonga, intliziyo yakho impompa igazi elingakumbi kuba iiseli zakho zifuna ioksijini engakumbi. |
| Inqanaba lentliziyo | Ngexesha lokuzilolonga, isantya sentliziyo siyanda ukuze kuhlangatyezwane nemfuno ekhulayo yeoksijini. |
| Umsebenzi weeseli zentliziyo | Ukuba amagumbi asezantsi (ii-ventricles) zentliziyo azisebenzi kakuhle, azikwazi ukupompa igazi elaneleyo emzimbeni. Oku kunokubonwa kwisifo sentliziyo. |
Yintoni iHemodynamic Instability?
Le yimeko enzima kakhulu. Ukungazinzi kwe-hemodynamic kwenzeka xa umzimba ungakwazi ukubonelela ngegazi elaneleyo. Le yimeko efuna unyango olungxamisekileyo. Sidla ngokuyibiza le meko yokwethuka . Yahlulwe yaba ziintlobo ezahlukeneyo kuxhomekeke kwisizathu.
- I-Cardiogenic - ngenxa yengxaki yentliziyo
- I-Hypovolemic - ngenxa yokuncipha kolwelo okanye umthamo wegazi emzimbeni
- Ukuthintela - ngenxa yokuthintelwa kwegazi emzimbeni
- Ukusasazwa - ngenxa yokwanda kakhulu kwemithambo yegazi
- I-Neurogenic - ngenxa yomonakalo kwinkqubo yemithambo-luvo
Ilinganiswa njani i-hemodynamics?
Ugqirha wakho angasebenzisa iintlobo ngeentlobo zovavanyo ukulinganisa imeko yakho ye-hemodynamic, ezinye zazo osenokuba uqhelene nazo.
| Uvavanyo | Wenza ntoni nje? |
|---|---|
| Uvavanyo loxinzelelo lwegazi | Uvavanyo lwenziwa kusetyenziswa isixhobo esiqhelekileyo sokulinganisa uxinzelelo lwegazi (iBP cuff). |
| I-ECG | Umsebenzi wombane wentliziyo uyajongwa ukuze kubonwe ukuba kukho na iipatheni zokubetha kwentliziyo ezingaqhelekanga. |
| I-Echocardiogram | Basebenzisa amaza esandi ukuthatha umfanekiso wentliziyo nokujonga ukuba amagumbi kunye neevalvu zentliziyo zisebenza kakuhle na. |
| Ukufakwa kwe-catheter kwintliziyo | Ityhubhu encinci (i-catheter) idluliselwa ngemithambo yegazi iye entliziyweni ukuze ilinganise uxinzelelo olungaphakathi entliziyweni kwaye ijonge ukusebenza kweevalvu. |
| Uvavanyo lwetafile ethambekileyo | Kwabo basoloko bephelelwa ngamandla, kwenziwa uvavanyo ukuze kubonwe ukuba uxinzelelo lwegazi kunye nesantya sentliziyo zitshintsha njani xa imeko yomzimba itshintsha. |
