ABSTRACT: In this study, temporal components of respiratory signals during wake and sleep are ana-
lyzed in terms of complexity. The data—Inspiratory Time (T
I
) and Total Respiratory Time (T
TOT
)—was
taken from the MIT polysomnographic database. The dynamic of each state (wake and sleep) is ana-
lyzed in terms of four indexes: Correlation dimension, Lyapuno ...
