37. Cardiac output :- Flashcards
Normal cardiac output =
Cardiac output =
177
CO = SV x HR Therefore CO is directly proportional to 1. 2.
177
Stroke volume depends on :-
1.
2.
3.
177
Preload is
Preload =
Frank starling law :-
Increase EDV =
Increase contraction =
177
Contractility :-
Contractility is directly proportional to :- CO
Afterload means :-
Afterload is inversely proportional to :-
178
Best marker

Contractility:-
Contractility is phenomenon of :-
Positive inotropic drug like
Increase contractility lead to increase in :-
178
Measurement of cardiac output :-
FICKS principle
Amount of O2 consumption =,,,,,,,,,,,,,,,,,,,x,,,,,,,,,,,,,,
Blood flow is considered as :-
Therefore
CO :- ,,,,,,,,,,,,,,,,,/,,,,,,,,,,,,,,,,,
