cardio physio equations Flashcards
1
Q
CO = (simple equation)
A
CO= SV X HR
2
Q
CO in terms of Mr. Fick
A
CO = Rate of O2 consumption / arterial O2 - venous O2
3
Q
MAP in terms of CO
A
MAP = CO x TPR
4
Q
MAP in terms of systolic and diastolic pressure
A
MAP = 2/3 diastolic bp + 1/3 systolic bp
5
Q
pulse pressure
A
PP = Systolic - diastolic bp
6
Q
what is the relationship between SV and PP
A
PP is directly proportional to SV
7
Q
relationship between PP and arterial compliance
A
PP is inversely proportional to arterial compliance
8
Q
SV =
A
SV= EDV - ESV
9
Q
wall tension =
A
wall tension = pressure x radius / 2xwall thickness
