In the third edition of the International Classification of Sleep Disorders (ICSD-3), obstructive sleep apnea is classified amongst the sleep-related breathing disorders and is divided in two categories, namely adult OSA and pediatric OSA. [5] Obstructive sleep apnea is differentiated from central sleep apnea (CSA), which is characterized by ...
Symptoms of infantile apnea occur most frequently during the rapid eye movement (REM) stage of sleep. [4] The nature and severity of breathing problems in patients can be detected in a sleep study called a polysomnography which measures the brain waves, heartbeat, body movements and breathing of a patient overnight. [4]
The respiratory disturbance index (RDI)—or respiratory distress Index—is a formula used in reporting polysomnography (sleep study) findings. Like the apnea-hypopnea index (AHI), it reports on respiratory distress events during sleep, but unlike the AHI, it also includes respiratory-effort related arousals (RERAs). [1]
Sleep apnea may be categorized as obstructive sleep apnea (OSA), in which breathing is interrupted by a blockage of air flow, central sleep apnea (CSA), in which regular unconscious breath simply stops, or a combination of the two. [1] OSA is the most common form. [1]
The Sleep Timing Questionnaire is a 10-minute self-administration test that can be used in place of a 2-week sleep diary. The questionnaire can be a valid determinate of sleep parameters such as bed time, wake time, sleep latency, and wake after sleep onset. [6]
Tayside children's sleep questionnaire: A ten-item questionnaire for sleep disorders in children aged between one and five years old. [7] [8] [9] Children's Sleep Habits Questionnaire. [10] Cleveland Adolescent Sleepiness Questionnaire (CASQ): There are 16 items to measure extreme sleepiness during the day in adolescents aged 11–17 years old ...
The Epworth Sleepiness Scale has been validated primarily in obstructive sleep apnea, though it has also shown success in detecting narcolepsy and idiopathic hypersomnia. [3] It is used to measure excessive daytime sleepiness and is repeated after the administration of treatment (e.g., CPAP ) to document improvement of symptoms. [ 6 ]
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. Hypopnea is a partial collapse of your airway, limiting breathing.
