Swan Ganz Flashcards
What size tubing would you need for the swan ganz catheter?
Not more than 4 feet
How much pressure is needed for the TYPCO pressure bag?
300 mmHg
Name the equipment needed for the Swanz Ganz or PAC catheter?
Catheter Tubing (not greater than 4') Stopcocks--Heparnized NSS Tyco Pressure Bag Pressure Transducer--convert pressure to electrical signal Amplifier Recording Device ECG
Where should the transducer be placed?
At midchest
What would happen if you placed the transducer above the chest level?
The pressure would be falsely low
What locations should the PAC be inserted?
Right Internal Jugular Subclavian Basilic Cephalic Femoral
What is the yellow port?
Distal port
What the red port called?
Balloon port
What is the blue port called
Proximal
What is the port that monitors temperature and which temperature and why?
thermistor, measures blood temperature needed for CMO
What is the distal port used for?
Monitors pressure (PAP & PWP)
Obtain venous blood samples
Inject medications
What is the distal port normally infused with and why?
Infused with heparnized solution because it must constantly monitor pressure
What is the red port used for?
Insertion purposes to allow float
And permits wedging when you want PCWP reading
What marking does the blue port stop at?
30 cm from tip
How much air is inserted into balloon?
1.5 ml of air
Where does the opening of the blue line sit?
At opening of right atrium
What are the uses of the proximal or blue port?
RA pressure
Administration of drugs & fluids
Sample blood
Inject saline for CMO reading
What is the purpose of the VIP?
It provides an extra port for medications & sampling so that the proximal can be continuously used for pressure & not turned off
What can the #6 line do if present?
Atrial/Ventricular Cardiac Pacing
Continuous cardiac output
Ventricular Port VIP
Right ventricular Ejection Fraction Catheter
Where should the catheter be set at? A. Zone 1 B. Zone 2 C. Zone 3 D. All of the above
C. Zone 3 because more blood is located in this zone
What is a normal pressure measurement provided by PAC in the right atrium?
2-6 mmHG
What is a normal pressure measurement provided by PAC in right ventricle?
20-30–systole
0-5–diastole
What is a normal pressure measurement of PAC in pulmonary artery?
20-30 –systole
6-15 mmhg in diastole
What is the normal mean pressure of the pulmonary artery?
10-20 mmHg
What is a normal pulmonary capillary wedge pressure?
4-12 mmHg
Why is the pressure in the right ventricle & pulmonary artery the same?
Because the pulmonary SL valve is open
What is the cause of the dicrotic notch?
Caused by the closing of the valve in the pulmonary artery
Which side of the heart is affected by cardiogenic pulmonary edema?
Left Heart
