Polysomnogram

Aka: Polysomnogram, Sleep Study, Obstructive Apnea, Obstructive Hypopnea, Upper airway resistance syndrome, Respiratory Effort Related Arousal, Apnea and Hypopnea Index, Respiratory Disturbance Index, UARS, RERA, AHI, RDI
  1. Indications
    1. Sleep Apnea
      1. Central Sleep Apnea
      2. Obstructive Sleep Apnea
  2. Definitions
    1. Obstructive Apnea
      1. Air flow decreases 70% for at least 10 seconds with persistent respiratory effort
    2. Obstructive Hypopnea
      1. Air flow decreases 30% for at least 10 seconds with oxygen desaturation >3%
    3. Upper airway resistance syndrome (UARS)
      1. Variant of Obstructive Sleep Apnea
      2. Less airway collapse and less oxygen desaturation
      3. Frequent arousals occur as with OSA/H
    4. Respiratory Effort Related Arousal (RERA)
      1. Abnormal respiratory event associated with an arousal (e.g. gasping) per hour
    5. Apnea and Hypopnea Index (AHI)
      1. Number of Obstructive Apnea and Obstructive Hypopnea events per hour
    6. Respiratory Disturbance Index (RDI)
      1. Apnea and Hypopnea Index (AHI) and Respiratory Effort Related Arousal (RERA)
  3. Grading
    1. Respiratory Disturbance Index (RDI) <5
      1. No Obstructive Sleep Apnea
      2. No treatment necessary except:
        1. Disruptive snoring
        2. Serious comorbidity (e.g. CHF)
        3. Upper airway resistance syndrome
          1. Consider if significant Sleepiness and Fatigue
    2. Respiratory Disturbance Index (RDI) 5 to 15
      1. Mild Obstructive Sleep Apnea
      2. Consider Upper airway resistance syndrome
    3. Respiratory Disturbance Index (RDI) 16 to 30
      1. Moderate Obstructive Sleep Apnea
    4. Respiratory Disturbance Index (RDI) >30
      1. Severe Obstructive Sleep Apnea

Polysomnography (C0162701)

Definition (MSH) Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.
Definition (NCI) A group of recordings taken during sleep that shows brain wave changes, eye movements, breathing rate, blood pressure, heart rate, and the electrical activity of the heart and other muscles. A polysomnogram may be used to help diagnose sleep disorders.
Definition (PSY) Simultaneous recording of electrophysiologic activity during sleep.
Definition (CSP) simultaneous and continuous monitoring of relevant normal and abnormal physiological activity during sleep.
