Hemodynamic monitoring involves special indwelling catheters that provide information
about blood volume and perfusion, fluid status and how well the heart is pumping.
Arterial lines are placed in the radial (most common), brachial or femoral artery. What
should you Monitor for? - ANSWER-Monitor circulation in the limb with the arterial line.
Such as capillary refill, temperature, color. Arterial lines are not used for IV fluid
administration
The pulmonary artery (PA) catheter is inserted into a large vein (internal jugular,
femoral, subclavian, brachial) and threaded through the right atria and ventricles into a
branch of the pulmonary artery. PA catheters have multiple lumens, ports and
components that allow for various hemodynamic measurements, blood sampling and -

What is expected range for pulmonary artery wedge pressure (PAWP)? - ANSWER-4 to
12
What is the expected range for cardiac output - ANSWER-4 to 7 L/minute
What is expected range for mixed venous oxygen saturation - ANSWER-60% to 80%
When should a nurse anticipate lower hemodynamic values? - ANSWER-In older
