title: Respiratory pauses and apnea during nocturnal sleep in mentally retarded infants.
abstract: Respiratory pauses (ResP), apnea (Ap) and periodic respiration (PerR) observed in 42 mentally retarded infants (from 9 to 50 weeks of age post term) were studied throughout nocturnal sleep. All subjects had ResP in the recordings. The range of ResP rates was 4.1-42.1/h, and the mean was 13.5/h. Ap occurred in 22 out of 42 subjects. The range of Ap occurrence (10-15 sec duration) among subjects was 1-10, with a mean of 4.1. Moreover, in 4 out of 22 subjects, Aps of greater than 15 sec duration were seen. In 30 out of 42 subjects, PerR occurred. The range of occurrence of PerR among subjects was 1-35, and the mean was 9.6.
