Cardiodynamics Definitions and Values Flashcards
Define End Diastolic Volume (EDV) and give values for males and females?
Volume of blood in ventricle at end of atrial systole
Males 120 mls
Females 100 mls (80-100mls)
Define stroke volume and give values for males and females
Give equation for stroke volume
The volume ejected from the ventricles
EDV - ESV
Males = 70 mls Females = 60 mls
Define end systolic volume
The volume of blood left in the ventricle following contraction
50 mls males
50 - 45 mls females
What is cardiac output?
Give equation
Give values
The volume of blood pumped by the heart per unit time (L/min)
CO = Heart rate by stroke volume
- 6L = males
- 9 L = females
What is blood pressure?
The force exerted by the blood against any unit area of vessel wall
Units = mmHg
What is MSAP?
Give equation
Give values
Mean systemic arterial pressure - average blood pressure during a single cardiac cycle
Diastolic + 1/3rd (systolic + diastolic)
Between 70 - 100 mmHg
What is pulse pressure?
2
The difference between systolic and diastolic pressures
Between 40 and 60 mmHg
