Overview

The American Academy of Sleep Medicine published a diagnostic manual guidelines.[1][2]

Diagnosis Criteria

DSM-V Diagnostic Criteria for Central Sleep Apnea

Either criterion 1 or 2 must be met:

1. Evidence by polysomnography of at least five obstructive apneas or hypopneas per hour of sleep and either of the following sleep symptoms:

  • Nocturnal breathing disturbances: snoring, snorting/gasping, or breathing pauses during sleep.
  • Daytime sleepiness, fatigue, or unrefreshing sleep despite sufficient opportunities to sleep that is not better explained by another mental disorder (including a sleep disorder) and is not attributable to another medical condition.

2. Evidence by polysomnography of 15 or more obstructive apneas and/or hypopneas per hour of sleep regardless of accompanying symptoms.

  • Apnea Hypopnea Index (AHI) - the number of apneas or hypopneas recorded during the study per hour of sleep
  • Based on the AHI, the severity of OSA is classified as follows:
  • None/Minimal: AHI < 5 per hour
  • Mild: AHI ≥ 5, but < 15 per hour
  • Moderate: AHI ≥ 15, but < 30 per hour
  • Severe: AHI ≥ 30 per hour
  • The RDI is the average number of respiratory disturbances (obstructive apneas, hypopneas, and respiratory event–related arousals [RERAs]) per hour.


DSM-V Diagnostic Criteria for Central Sleep Apnea[3]

A. Evidence by polysomnography of five or more central apneas per hour of sleep.

AND

B. The disorder is not better explained by another current sleep disorder.

Specify whether:

  • Idiopathic central sleep apnea: Characterized by repeated episodes of apneas and hypopneas during sleep caused by variability in respiratory effort but without evidence of airway obstruction.
  • Cheyne-Stokes breathing: A pattern of periodic crescendo-decrescendo variation in tidal volume that results in central apneas and hypopneas at a frequency of at least five events per hour, accompanied by frequent arousal.
  • Central sleep apnea comorbid with opioid use: The pathogenesis of this subtype is attributed to the effects of opioids on the respiratory rhythm generators in the medulla as well as the differential effects on hypoxic versus hypercapnic respiratory drive.

Specify current severity:

Severity of central sleep apnea is graded according to the frequency of the breathing disturbances as well as the extent of associated oxygen desaturation and sleep fragmentation that occur as a consequence of repetitive respiratory disturbances.
