title: The effects of partial and complete mechanical occlusion of the nasal passages on sleep structure and breathing in sleep.
abstract: The influence of partial and complete mechanical obstruction of the nasal passages was investigated in 10 normal young adults (5 males and 5 females) without any ENT abnormalities. Nasal obstruction caused a significant increase in the number of apneas during sleep, in the number of microarousals associated with non-apneic breathing disorders in sleep, and in the amount of wake-time within sleep.
