The Apnea–Hypopnea Index or Apnoea–Hypopnoea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep. Apnea is the complete absence of airflow through your nose and mouth. Hypoapnea is a partial collapse of your airway, limiting breathing. Apneas (pauses in breathing) must last for at least 10 seconds and be associated with a decrease in blood oxygenation to be considered. Combining AHI and oxygen desaturation gives an overall sleep apnea severity score that evaluates both the number of sleep breathing disruptions and the degree of oxygen desaturation (low oxygen level in the blood) during said disruptions.

  • Der Apnoe-Hypopnoe-Index (AHI) bezeichnet in der Schlafmedizin die durchschnittliche Anzahl von Apnoe- und Hypopnoe-Episoden pro Stunde Schlaf. Er ist ein Hinweis auf die Schwere einer „Schlafbezogenen Atmungsstörung“ und wird auch bei der Kontrolle von Therapieerfolgen verwendet. (de)
  • The Apnea–Hypopnea Index or Apnoea–Hypopnoea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep. Apnea is the complete absence of airflow through your nose and mouth. Hypoapnea is a partial collapse of your airway, limiting breathing. Apneas (pauses in breathing) must last for at least 10 seconds and be associated with a decrease in blood oxygenation to be considered. Combining AHI and oxygen desaturation gives an overall sleep apnea severity score that evaluates both the number of sleep breathing disruptions and the degree of oxygen desaturation (low oxygen level in the blood) during said disruptions. The AHI is calculated by dividing the number of apnea events by the number of hours of sleep. The AHI values for adults are categorized as: * Normal: AHI<5 * Mild sleep apnea: 5≤AHI<15 * Moderate sleep apnea: 15≤AHI<30 * Severe sleep apnea: AHI≥30 For children, because of their different physiology, an AHI in excess of 1 is considered abnormal. Underage pediatric patients presenting with AHI of 2 or greater will often be referred for treatment. (en)
  • 呼吸暂停低通气指数(英語:Apnea–Hypopnea Index,AHI)又称睡眠呼吸中止指數,是每小时睡眠时间内呼吸暂停加低通气的次数。呼吸暂停低通气指数是一個用來表示睡眠呼吸暂停的嚴重程度的數值。 (zh)
