Pulmonary artery catheter Flashcards
What do you need to insert a pulmonary artery catheter?
central line with introducer port
Which port allows the catheter into the pulmonary artery when advanced?
Red
What is the maximum amount of air that the PAC balloon should be filled with?
1.5 mL
what should an anesthetist always do whenever the catheter is withdrawn?
DEFLATE the balloon
innermost lumen that goes all the way to the distal tip of catheter
PA distal port YELLOW
2 things the yellow distal port monitors
- pulmonary artery pressure 2. pulmonary capillary wedge pressure
what mark does the blue port of the pulmonary artery catheter go to?
30 cm mark
port used to inject cold saline
proximal injectable port; blue port
what does the blue port monitor?
CVP
what is the proximal infusion port (white) connected to?
series of stopcocks and used to run drug infusions directly into the heart
which port allows measurement of blood temperature and cardiac output?
thermistor port (yellow)
when cardiac output is measure what two things can be calculated?
SVR and PVR
8 functions of the swan ganz catheter
- measures PAP 2. measure central venous pressure 3. measures pulmonary capillary wedge pressure 4. can calculate cardiac output 5. can calculate SVR and pulmonary vascular resistance 6. delivers drug infusions 7. insertion of pacing wires 8. withdrawing air emboli from the heart via a port on the pulmonary artery catheter
describe what pulmonary capillary wedge pressure is
when the balloon wedges against the walls of the pulmonary artery and the distal tip of the catheter can no longer sense the pressure coming form the forward flow of the right ventricle and senses pressure backing up from the left atrium
PCWP is an estimate of ___
left atrial pressure
