Hemodynamic Calculations

Question 1

Cardiac Output

Answer 1

CO = HR x SV

norm: 5-6 L/min

Question 2

Cardiac Index

Answer 2

CI = CO/BSA

norm: 2.8 - 4.2 L/min/m ^3

Question 3

Stroke Volume

Answer 3

SV = EDV - ESV 
SV = CO x (1000/HR) 

norm: 50 - 100 mL/beat

Question 4

Stroke Volume Index

Answer 4

SVI = SV/BSA

norm: 30-65 mL/beat/m^3

Question 5

Ejection Fraction

Answer 5

EF = EDV - ESV/EDV x 100

norm = 60-70%

Question 6

Mean Arterial Pressure

Answer 6

MAP = CO x SVR/80 + CVP

MAP = SBP + 2(DBP) / 3

norm: 70-105 mmHg

Question 7

Pulse Pressure

Answer 7

Pulse pr = SBP - DBP

SV output/arterial tree compliance

norm: 40 mmHg

Question 8

Systemic Vascular Resistance

Answer 8

SVR = MAP - CVP/CO x 80

norm: 900-1400 dynes/sec/cm^-5

Question 9

Systemic Vascular Resistance Index

Answer 9

SVRI = MAP - CVP/CI x 80

norm: 1500-2400 dynes/sec/cm^-5/m^2

Question 10

Pulmonary Vascular Resistance

Answer 10

PVR = PMAP - PAOP/CO x 80

norm: 150-250 dynes/sec/cm^-5

Question 11

Pulmonary Vascular Resistance Index

Answer 11

PVRI = PMAP - PAOP/CI x 80

norm: 250 - 400 dynes/sec/cm^-5/m^2
