Cardiac Hemodynamics Flashcards
Cardiac index
2.8-4.2 L/min/m2
Co norm range
4-8 L/minute
Pre load left ventricle measured by
Pawp
Preload of right ventricle measured by
Cvp / ra pressure
Systemic vascular resistance indicates
Lv after load
Paop normal range
6-12 mm hg
Cvp/ra pressure norm range
2-6 mm hg
Pawp/la pressure norm range
6-12mmHg
Define after load
Pressure ventricle must generate to open the semilunar valve and eject its contents
Lv afterload
Systemic vascular resistance
