Presentation Transcript

  1. PA Line etiquette Sharon /Penny

  2. Presentation Objectives • Review indications for the use of PA catheter with heart failure patients. • The difference of the four major types of PA catheters. • Review the pressure data collected for the PA and catheter. • Review the risks of the use of the PA catheter. • Understand the general rules of handling an inserted PA catheter.

  3. Free online education • PACEP

  4. Invented the PA Cath • Dr Swan • Dr Ganz

  5. Indications • “There are no universally accepted indications for pulmonary artery catheterization because pulmonary artery catheters have not been shown to improve outcomes.” • However, there are situations in which pulmonary artery catheterization may be helpful to manage and assess patients • www.UpToDate.com

  6. Invasive Hemodynamic Monitoring • Invasive hemodynamic monitoring can be useful for carefully selected patients with acute HF who have persistent symptoms despite empiric adjustment of standard therapies, and • a. whose fluid status, perfusion, or systemic or • pulmonary vascular resistances are uncertain; • b. whose systolic pressure remains low, pr is associated with symptoms, despite initial • therapy; • c. whose renal function is worsening with therapy; • d. who require parenteral vasoactive agents; or • e. who may need consideration for advanced device • therapy or transplantation.

  7. Indications for PA Line • Diagnostic= Right Heart Cath • -Differentiate cause of shock • Cardiogenic/Hypovolemic /Septic • -Differentiate mechanism of pulm edema • Cardiogenic/noncardiogenic • -Evaluate pulmonary hypertension

  8. Indications for PA Line • Therapy • Heart Failure • Complicated MI • Cardiac Surgery • Pharmacological therapy • -Vasopressors, Inotropes, Vasodilators • Nonpharmacological therapy • -fluid management ieUltrafiltration

  9. Contra-indications • R.BBB • Tricuspid/pulmonic valve stenosis • Artificial tricuspid/pulmonic valves • Right Atrial/Ventricular mass • New pacemaker • Coagulopathy

  10. Types of PA Lines available • Standard • VIP • CCO • Pacing

  11. PA Catheter

  12. PA Catheter • Flow directed/balloon tipped catheter • 110cm in length, markings every 10cm • Tip of catheter in the pulmonary artery • Measures intra-cardiac pressures • Sample blood

  13. Color coded • Yellow – distal – pulmonary artery (PAP) • Blue – proximal – right atrium (CVP) • White – VIP – venous infusion port • Red – balloon inflates with 1.5cc gated syringe • Thermistor – measures blood temp • Continuous Cardiac Output (CCO) • Optical module – mixed venous oximetry(SvO2)

  14. Hemodynamic Information • Central Venous Pressure • Pulmonary Artery Pressure • Pulmonary Artery Occlusion Pressure (wedge) • Cardiac Output/Index • Mixed venous saturation • SVR, PVR, Stroke volume

  15. Risks associated with PA Line • Complicated vascular access (pneumothorax, hematoma, arterial puncture, Right ventricle perforation) • Arrhythmias (heart block, ventricular tachycardia/fibrillation) • Catheter knotting / Catheter migration • Pulmonary thrombosis and infarction • Tricuspid/Pulmonary Valve damage • Infection • Pulmonary artery rupture

  16. Arrhythmias • PVC’s and V.tach when in R. Ventricle • L.BBB + R.BBB = CHB

  17. PA Pressures Text Book Levels • CVP 0-7 • PAS 15-30 • PAD 8-15 • PAM 10-17 • PAOP M 6-12

  18. Catheter knotting

  19. Catheter migration • Know your waveforms!!! • Forward -> wedge -> pulmonary infarction • Backward -> fall into RV -> VT

  20. Pulmonary Artery Rupture • Usually fatal • Hemoptysis, hypoxia -> cardiac arrest • Intubate, PEEP -> surgery

  21. Right Heart Cath/PA Insertion

  22. Right Heart Cath/PA Insertion • YouTube - Swan Ganz Catheter Placement

  23. Errors • Incorrect transducer location • Inaccurate calibration • Over/under-damping of transducer • Incorrect catheter position • ***Incorrect interpretation of information***

  24. Incorrect transducer location Stopcock at phlebostatic axis. 4thintercostal space /midpoint of anterior-posterior chest

  25. External & Internal PA

  26. Improper Leveling

  27. Square wave test • Under-damping • Excessive tubing or stopcocks • systolic overshoot (the artificial exaggeration of systolic pressure) • Caused by the patient: hypertension, atherosclerosis, vasoconstriction, aortic regurgitation, or hyperdynamicie sepsis • Over-damping • Air bubbles, blood, kinked or non-pressure tubing • Caused by the patient: aortic stenosis, vasodilatation, or low cardiac output state

  28. Correct Placement • Correct Placement is in Zone 3 because

  29. Do • Ensure accuracy of your numbers • Measure waveforms • Draw blood out of correct port • Aseptic technique

  30. What is the wave forms looking at?

  31. Don’t • Throw away syringe or replace syringe • Put more air in balloon • Get heart failure patient out of bed without MD order • Infuse anything through the yellow port • Manipulate PA

  32. Heparin-coated • Do you know if the PA lines are heparin coated at this facility? • Can you use a heparin coated PA line on a patient with HIT?
