Derived Hemodynamic Data

Question 1

MAP =

Answer 1

DBP + 13SBP-DBP

SBP + 2xDBP3

Question 2

Mean pulmonary artery pressure (MPAP)

Answer 2

10-20 mmHg

Question 3

MPAP =

Answer 3

PADP + 13PASP-PADP

PASP + 2xPADP3

Question 4

Cardiac Index (CI)

Answer 4

CO/BSA = 2.5 - 4.0 L/min/m2

Question 5

Stroke volume (SV):

Answer 5

CO/HR x 1000 = 60 - 100 ml/beat

Question 6

Increased SV is associated with what?

Answer 6

Bradycardia and positive inotropic agents which increase contractility

Systemic vascular resistance (SVR)

Answer 7

MAP-RAP x CO

12.5-20 mmHg X min/L

Question 8

Systemic vascular resistance represents what?

Answer 8

The load applied to the left ventricular muscle during ejection

Question 9

Mean arterial pressure (MAP)

Answer 9

70-105 mmHg

Question 10

Pulmonary vascular resistance (PVR)

Answer 10

80 X (MPAP - PAWP)/CO =

Question 11

Pulmonary vascular resistance is an index of what?

Answer 11

The resistance offered by the pulmonary capillaries to the systolic effort of the right ventricle
