Questions and CORRECT Answers
Serum Potassium 3.5-5 mEq/L
PR interval <0.20 sec (0.12-0.20)
QRS interval <0.12 sec
Normal lab values for the following: Central Venous Pressure (CVP) in adults 2-8 mmHg
Cardiac Output (CO) in adults 4-8L/min
Cardiac Index (CI) in adults 2.2-4L/min/m^2
MAP in adults 70-105 mmHg
Systemic Vascular Resistance (SVR): systemic vascular resistance→ resistance the left
ventricle must overcome to perfuse body
Wedge Pressure (PAOP/PAWP): estimates the left atrial pressure by "looking
Significance of the following (not required through" the lungs
to memorize actual normal ranges):
Stroke Volume: volume of blood pumped in one pump/stroke
Ejection fraction: ejection fraction→ percent of blood ejected from left ventricle
with each beat
, Norepinephrine (catecholamine)
