Pulmonary Artery Catheter Flashcards
How is a Swan Ganz catheter inserted?
Through a central line with an introducer port
Best insertion location for pulmonary artery catheter
R IJ
Second best insertion location for pulmonary artery catheter
L subclavian vein
Purpose of red port
To carry the catheter to the pulmonary artery when advanced
Balloon port characteristics
- Located proximal to the distal tip of the catheter, red port connected to the 3ml balloon syringe
- Balloon should only be inflated when advancing
- Balloon should not be filled with more than 1.5 ml of air
- Balloon should be deflated when withdrawing to avoid possible myocardial or valve damage
Innermost lumen that goes all the way to the distal tip of the catheter
PA distal port, yellow
Connected to transducer tubing to monitor pulmonary artery pressure and pulmonary capillary wedge pressure
PA distal port, yellow
Goes to 30 cm mark of pulmonary artery catheter, connected to transducer tubing for CVP monitoring
Can be used to inject cold saline for thermodilution
Proximal injectate port, blue
Goes to 30 cm mark of pulmonary artery catheter, connected to series of stopcocks that are used to run drug infusions to the heart
Proximal infusion port, white
Allows measurement of blood temperature, cardiac output
Thermistor port, yellow
Benefits of the Swan Ganz catheter
- Measure pulmonary artery pressure
- Measure central venous pressure
- Measure pulmonary capillary wedge pressure
- Calculate cardiac output
- Calculate SVR and PVR
- Deliver drug infusions
- Insert pacing wires
- Withdraw air emboli
How to insert Swan Ganz catheter
- Start a central line with introducer port
- Hook up pressure transducers (CVP and PAP)
- Inflate balloon and advance into pulmonary artery, using waveform as guideline
Waveform at R atrium
5-12 mmHg
20-25 cm at skin
Waveform at R ventricle
15-30/0-8 mmHg
30-35cm at the skin
Waveform at pulmonary artery
15-30/5-15 mmHg
40-55cm at the skin
