Podcast # 474: Obesity Hypoventilation Syndrome

Author: Peter Bakes, MD

Educational Pearls:

  • The differential diagnosis for pedal edema includes issues in the heart, kidney, and liver
  • Obesity hypoventilation syndrome (OHS) is an important and common cause of right heart failure. Nighttime hypoventilation leads to pulmonary hypertension, causing right heart strain followed by right heart failure
  • OHS criteria includes obesity, sleep disordered breathing, and alveolar hypoventilation (PaCO2 > 45 mmHg)
  • The causes of OHS are multifactorial, and include mechanical problems with breathing and hormonal changes
