Subjektive gener og søvnapnø blandt personer henvist til et søvncenter. En spørgeskemaundersøgelse

The aim of this study was to evaluate the relation between symptoms and clinical characteristics and the frequency of increased apnoea and hypopnoea activity. The study population consisted of 135 persons referred to a sleep centre. One hundred and fifteen patients (85%) completed a questionnaire and were subsequently monitored during one night's sleep. Fifty-two persons (45%) had an Apnoea Hypopnoea Index (AHI = the mean number of apnoea and hypopnoea episodes per hour of sleep) > or = 10. Forty-one (36%) had an Apnoea Index (AI = the mean number of apnoea per hour of sleep) > or = 10. Symptoms and clinical characteristics had no significant correlation to increased apnoea activity; however, there was a significant relationship between self-reported frequent breathing pauses during sleep and increased AHI and AI. Symptoms and clinical characteristics are not capable of identifying persons with increased apnoea activity.
