Intliziyo yakho isebenza kakuhle kangakanani? Masithethe ngeCardiac Output!

Namhlanje siza kuthetha ngentliziyo, elilungu elibaluleke kakhulu emzimbeni wethu. Ngokukodwa, siza kuthetha ngendlela intliziyo ehambisa ngayo igazi emzimbeni wethu ngempumelelo, okubizwa ngokuba yi -cardiac output . Nangona la mazwi esenokubonakala ematsha kuwe, alula kakhulu. Makhe sibone ukuba oku kuthetha ukuthini ngokwenene, akunjalo?

Yintoni imveliso yentliziyo? Ngamafutshane...

Ngamafutshane, ukuphuma kwentliziyo sisixa segazi esikhutshwa yintliziyo yakho emzimbeni wakho ngomzuzu omnye. Oku kudla ngokulinganiswa ngeelitha. Oogqirha babala oku nge-equation elula. Kufuna izinto ezimbini:

1. Umthamo weStroke: Eli linani legazi elimpontshelwa yintliziyo yakho emzimbeni wakho ngalo lonke ixesha ibetha, oko kukuthi, ngentliziyo enye. Eli nani linokuhluka. Eli nani legazi linokwanda okanye linciphe kuxhomekeke kwimpilo yentliziyo yakho nokuba uphumle okanye wenza umsebenzi othile.

2. Isantya sentliziyo: Mhlawumbi ukhe weva ngale nto. Eli linani lexesha intliziyo yakho ibetha ngalo ngomzuzu. Ngokwesiqhelo, isantya sentliziyo yomntu ophilileyo kufuneka sibe phakathi kwe-60 kunye ne-100 beats ngomzuzu xa ephumle. Oku kuyanda xa uzilolonga kwaye kuyancipha xa uphumle.

Ngoko ke, xa sizazi zombini ezi zinto, singafumana ixabiso lilonke sisebenzisa i-equation ethi Cardiac Output = Stroke Volume x Heart Rate .

Cinga ngale ndlela. Unyuka izinyuko ngokukhawuleza. Izihlunu zakho zifuna ioksijini engaphezulu, akunjalo? Ngoko ke isantya sentliziyo yakho siyanda, kwaye intliziyo yakho izama ukwandisa inani legazi eliyipompayo ngexesha (umthamo westroke). Kulapho ke ukuphuma kwentliziyo yakho kunyuka khona, kuba umzimba wakho udinga igazi neoksijini engaphezulu.

Oogqirha bakhangela nini esi siphumo sentliziyo?

Kulungile, ngoku unombuzo, oogqirha bakhangela nini esi sifo sentliziyo, akunjalo? Kunokubakho izizathu ezininzi.
