Question Answer
________ is a measure of pressures in the left atrium and is equal to the end diastolic pressure.
Show Answer
The Pulmonary Artery Wedge Pressure (PAWP), the same thing as a PCWP.
________ is a direct measurement of pressures in the pulmonary vein.
Show Answer
The Pulmonary Artery Wedge Pressure (PAWP), the same thing as a PCWP.
A _______ measures pressures in the atria and gives a picture of circulating volume, thus guiding fluid replacement.
Show Answer
Central venous pressure (CVP)
Always check with the doctor if a PCWP (PAWP) goes above _______.
Show Answer
20, or if it deviates dramatically from the patient norms
To maximize preload, a patient's PAWP/PCWP should be between _________.
Show Answer
15-20
_________ are used to increase a pulmonary artery wedge pressure (PAWP), thereby increasing preload.
Show Answer
Infusions of blood, solutions or albumin
_________ are used to decrease a pulmonary artery wedge pressure (PAWP), thereby decreasing preload (as in cases of fluid overload).
Show Answer
Diuretics
What does pulmonary artery wedge pressure (PAWP) measure?
Show Answer
Pressure in the left side of the heart, the pumping ability
A _______ represents pressure changes during a cycle of systole and diastole.
Show Answer
Wave
What is a normal central venous pressure (CVP)?
Show Answer
2 to 5

A CVP of _______ is a signal to worry about the patient. A CVP of _____ is a sign of a definite problem.
Show Answer
CVP of 6, worry. CVP of 8, there's a problem
What does systemic vascular resistance (SVR) measure?
Show Answer
The afterload of the heart
What components make up the systemic vascular resistance (SVR) measurement?
Show Answer
Cardiac output plus the patient's blood pressure
For a patient with a Swan-Ganz catheter, the head of the bed should always be less than _______.
Show Answer
60
The _________ port of the Swan-Ganz is used to measure cardiac output.
Show Answer
Thermistor lumen port
The __________ port of the Swan-Ganz is used to administer medications and fluids. It is in the right atrium or superior vena cava.
Show Answer
Proximal lumen port (measures CVP)
The _______ port of the Swan-Ganz catheter is used to obtain blood samples. It is located in the pulmonary artery.
Show Answer
Distal lumen port (measures PAP & PAWP)
What are the three most common insertion sites for a Swan-Ganz catheter?
Show Answer
The internal jugular, subclavian or femoral arteries.
Where does the balloon of a Swan-Ganz catheter get wedged?
Show Answer
In a branch of the pulmonary artery (this is the distal lumen).
During a Swan-Ganz insertion, what should you watch the cardiac monitor for?
Show Answer
Watch pressures (should be 20-30 over 10-15) to let the physician know when he's in the correct chamber, and monitor for premature ventricular contractions which can quickly turn to ventricular tachycardia.
________ assists the nurse in determining fluid volume overload or depletion versus cardiac pump malfunction post abdominal aortic aneurysm grafting.
Show Answer
Hemodynamic monitoring
