CCRN Review- Hemodynamics
What value reflects right ventricular preload? - CVP or RA pressure



In hypovolemic shock, does SVR increase or decrease? - increase



CVP and PAOP are a measure of preload or after load? - preload



Heart rate x stroke volume =? - cardiac output



Stroke volume is dependent on what three concepts? - preload, contractility, and after load



PAOP is a measure of which ventricle? - left



SVR measures which ventricle? - left



PVR measures which ventricle? - right



PVR and SVR are a measure of preload or after load? - afterload



What is a normal cardiac output? - 4-8 L/min



If cardiac output becomes critically low, what will happen to BP? - it will decrease



Bradycardia results in high or low cardiac output? - low



What is the first sign of compensation for a low cardiac output? - increase in HR

, Why does tachycardia decrease cardiac output? - decreased filling time



As stroke volume increase, what happens to cardiac output? - it increases



What is a normal stroke volume? - 50-100 mL/beat



What value reflects left ventricular preload? - PAOP



Term for the volume in the ventricle at the end of diastole - preload

What is a normal cardiac index? - 2.5-4L/min/m2



Term for the resistance against which the ventricle must pump to open the pulmonic or aortic valve -
afterload



If after load increase, what happens to cardiac output? - decreases



What is a normal SvO2? - 60-75%



What is a normal PAOP? - 8-12



What is a normal PA pressure? - 20/8 to 30/15



What is a normal mean PA pressure? - less than 20



What is a normal SVR? - 800-1200



What is a normal PVR? - 50-250
