Pattern Of Dysautonomia In Patients With Functional Gastrointestinal Disorders

desaturations (p = 0.001) and 1 arousal (p N 0.05). No apneas were followed by desaturation and arousal. Hypopneas were the most frequent respiratory event and occurred primarily during sleep stage 1 and 2. In all FD-patients, we recorded 362 hypopneas with subsequent oxygen-desaturation that were followed by only 51 arousals. 12 hypopneas (p b 0.001) occurred in 3 controls (p= 0.085) and were followed by 3 arousals (p= 0.002).
