use in lab sleep testing instead of home for complicated sleep apnea

  • Home sleep apnea testing (HSAT) can often be used for simple sleep apnea
  • HSAT has lower sensitivity and higher specificity (high sensitivity rules out, high specificity rules in) compared to in lab testing
  • The two types of HSAT are WatchPAT and Alice One
  • Send patients to sleep labs for complicated sleep apnea:
    • hx of seizure, stroke
    • hypoxemia
    • daily narcotics
    • lung disorders: moderate COPD, pHTN, ILD
    • severe obesity BMI > 45
