Q

8 functions of the swan ganz catheter

A
  1. 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

Q

describe what pulmonary capillary wedge pressure is

A

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

Q

What should you do once the catheter wedges?

A

do NOT advance the catheter any further pull the catheter back 2-3 cm during cardiopulmonary bypass pull the catheter back if it wedges with <1.5 cm air

17
Q

4 ways for easier advancement during difficult swan insertion

A
  1. ask pt to deeply inhale as you advance 2. position the patient head up with a right lateral tilt 3. increase the cardiac output with inotropes 4. increase the stiffness of the catheter
18
Q

2 indications for Swan Ganz catheter insertion

A
  1. pts with low ejection fraction 2. pts with a history of pulmonary hypertension
19
Q

3 contraindications for Swan Ganz catheter insertion

A
  1. left bundle branch block 2. wolf parkinson white syndrome 3. tricuspid regurgitation
20
Q

5 complications of swan ganz catheter placement

A
  1. air embolism, arterial puncture, same as central line placement 2. pulmonary artery rupture 3. sustained ventricular ectopy 4. damage to cardiac structures 5. “knotting” on repeated insertion attempts
