1 Δεκ 2023 · Overall, the presence of REM, N2, sleep cycles, and N3 were associated with a normal sleep structure by experts. In contrast, wake, N1, and overall sleep fragmentation (i.e. a high amount of sleep stage changes per hour) contributed to an evaluation of an abnormal hypnogram.
In spite of normal sleep cycling and only minor disruption of sleep continuity, the hypnogram clearly illustrates a consistent pattern of REM-related hypoxemia during sleep due to central and obstructive apneas.

for transitioning between rapid eye movement (REM) and non-REM (NREM) sleep,5 adequately characterizing sleep-stage transitions is a priority to better define the influence of specific factors (e.g., age and sex) on normal sleep structure and orga-nization.
Recent experimental studies suggest that sleep disturbance may impair key processes that contribute to the development and maintenance of chronic pain, including endogenous pain inhibition and joint pain.
14 Ιαν 2024 · The hypnogram, showing the successive sleep stages on a time scale, is a graphic representation of the sleep architecture. It provides the appraiser with an impression of the overall sleep quality at a glance.
