1.
CO (Cardiac output) = _____x _______ 
HR x SV
normal is 48liters per minute 

2.
Stroke Volume SV= 
SV (stroke volume)= CO in ml’s divided by HR
Normal range= 60130ml 

3.
What is the formula for MAP (mean arterial pressure) 
Systolic BP + (2 x diastolic) divided by 3


4.
The patient has a BP of 140/90 calculate the MAP. 
step1: 140 + 2x90 = 320
step2: 320/3 = 106.6 answer: = 107mm/hg 

5.
FORMULA FOR ANGIOGRAPHIC SV(stroke volume) = 
End Diastolic volume minus the End systolic Volume
EDVESV 

6.
Calculate the ANGIOGRPAPHIC SV (STROKE VOLUME) GIVEN: • EDV=140ML • ESV= 40ML 
Formula:
EDVESV 140ml40ml = 100ml 

7.
What is the average SV (stroke volume) in adults? 
70ml
range is 60130ml 

8.
Given: CO 5liters/min Heart rate 80 Calculate the SV (stroke volume) 
Formula: SV= COin ml/HR
step 1: Change 5 liters to ml =5000ml step 2: Divide by heart rate of 80 5000/80=62.5 or 63ml/min 

9.
Given HR 90 SV 100ml Calculate the CO(cardiac output) 
CO=HRxSV
90x100=9000 CO=9000ml/min or 9L/min 

10.
Angiographic Cardiac output or LVMF (left ventricular minute flow) What is the Formula for LVMF? 
LVMF=
LV end diastolic volume  LV end systolic volume x Heart rate LVEDV  LVESV x HR 

11.
Calculate the LVMF or Angiographic Cardiac output Given: LVEDV = 140ml LVESV = 40ml HR = 66 bpm 
LVMF = LVEDV  LVESV x HR
step 1: 140ml  40ml = 100ml step 2: 100ml x 66 bmp=6600ml answer: LVMF = 6600ml/min or 6.6liters/min 

12.
RF REGURGITATION FRACTION DEFINITION 
The ratio of regurgitation to the LV total flow.
This is the most accurate form of cardiac output for patients with valvular regurgation. 

13.
Formula for RF %(Regurgitation Fraction) using Cardiac Output 
Formula for Regurgitation Fraction
LVMF  CO from Fick or TD divided by LVMF 

14.Calculate the RF% (regurgitation fraction)
Given LVMF is 6.6liters/min TD (thermodilution) CO is 4.56liters/min 
LVMF  CO from Fick or TD
divided by LVMF step 1: 6.6liters  4.56liters =2.04 liters Step 2: 2.04/6.6=.309 Step 3: .309 x 100 = 30.9% 

15.
Cardiac Index Formula for CI is 
CI= CO/BSA
Cardiac output divided by the Body Surface Area Normal values= 2.54.2 L/min/meter squared 

16.
What is BSA or Body Surface Area 
Body surface area: BSA. The total suface area of the human body. The BSA is used in many measurements in medicine, including the calculation of drug dosages and the amount of fluids to be administered IV.


17.
What is the Average BSA for men and for women? 
Average BSA for adult men: 1.9 m2
Average BSA for adult women: 1.6 m2 

18.
ANGIOGRAPHIC SV (STROKE VOLUME) DEFINITION 
THE AMOUNT OF BLOOD BEING EJECTED FROM THE LV DURING EACH CONTRACTION. THE ANGIOGRAPHIC SV can be calculated using the formula:
SV = EDVESV. End Diastolic Volume and End Systolic Volume must be calculated by using quantitative measurements of the LV angiography. Average Stroke Volume for adults is 70 ml. 

19. PVR
(Pulmonary Vascular Resistance) Formula 
(Mean PA) – (Mean PCW)
divided by CO Given: PA= 25/10/15 PCW=9/6/6 CO=6.8 (155)/6 = 1.3 HRU’s (Hybrid or Wood Units) 1.3 x 80 = 104 dynes/sec/cm5 ARU’s
