Formulas

Question 1

Fick

Answer 1

CO = (VO2) / (art O2 content - ven O2 content)

= (135 x BSA) / 13 x BSA x (art SpO2 - ven SpO2)

Question 2

SVR

Answer 2

= (MAP - CVP) x 80 / CO

Question 3

normal SVR

Answer 3

900 - 1300

Question 4

goal SVR in HF

Answer 4

800 - 1000

Question 5

SVR in sepsis

Question 6

PVR

Answer 6

= (mean PAP - PCWP) / CO

Question 7

normal PVR

Answer 7

5 no transplant

Question 8

RVSWI

Answer 8

= (mean PAP - CVP) x (CI/HR) x 1000

Question 9

goal/good RVSWI

Answer 9

> 400

Question 10

normal transpulmonic gradient

Question 11

concerning SpO2 change

Answer 11

step up >7% -> consider shunt

Question 12

Hakki equation (aortic valve)

Answer 12

aortic valve area = CO / square root (peak to peak gradient)

Question 13

Gorlin equation (aortic valve)

Answer 13

aortic valve area = CO / HR x systolic ejection period x 44.3 x square root (mean gradient)
