1/1

entral Venous Pressure 3-8 mm Hg (CVP,

AP) Measures preload of RA & RV

Systemic Vascular Resistance 800-1200 dynes

(SVR) Measures systemic resistance and

reflects afterload of Left Ventricle

Pulmonary Artery Wedge Pressure

8-12 mm Hg (PAWP, PWP)

Measures preload of LA &LV, and

reflects Left Ventricle End Diastolic

Volume

Pulmonary Artery Press

Systolic (PAP) = 25 systo

and 10 diastolic (Quarte

Dime) Systolic= amount

pressure needed to ope

Pulmonic Valve and sho

RVP when pulmonary va

open. Diastolic = resista

pulmonary vascular bed

when pulmonary valves

closed

Stroke Volume-60-100 ml/beat.

Ejection Fraction- 55-65%

Cardiac Output- 4-6L/minute

Cardiac Index- 2.5-4. Cardiac output in

relation to body mass

Pulmonary Vascular

Resistance- (PVR)
