Pearls from Dr. Kristin Burkart

56 y/o with progressive SOB found to have Pulm HTN


  • Useful Facts:
    1. Venous Blood Gas: Useful to screen for hypercarbia (not hypoxemia). If elevated, will need an ABG.
    2. RVSP on TTE: Estimation is with large S.E. - need RHC to formally evaluate
    3. If RVSP >50 unlikely acute process since this degree of elevation in pressures acutely would cause RV failure and HD compromise
    4. Shunt Physiology: Increasing FiO2 will only result in minimal improvement in PaO2. With serial ABGs on different O2 settings can actually calculate shunt fraction.  
      • Intrapulmonary Shunt Examples:
        • Hepatopulmonary Shunt
        • Hereditary hemorrhagic telangiectasia

  • Hemoptysis:

    Posted 11/10/16 02:15:48 PM by Adam Faye

  • Sarcoid Stages:
    1.  B/L hilar adenopathy (regression of nodes occurs in 75% of individuals)
    2.  B/L hilar adenopathy and reticular opacities (upper lobe predominant)
    3.  Reticular opacities with shrinking hilar nodes
    4.  Reticular opacities with evidence of volume loss
