For employers, an aging workforce carries comorbid implications where sleep disorders can induce debilitating medical issues including diabetes, heart disease, obesity, and stroke.Ī hypnogram is a practical resource to monitor and track the continuity of sleep architecture overnight, supporting additional testing procedures to help gauge sleep patterns. Since sleep decreases with age, many individuals are likely to experience a deficit of slow-wave sleep and subsequent REM deep sleep leading to insomnia due to inadequate sleep patterns. A hypnogram is a form of polysomnography it is a graph that represents the stages of sleep as a function of time. The diagnosis of sleep disorders often warrant the use of hypnogram results to correlate a patient’s symptoms - for instance, immediate REM sleep can suggest narcolepsy.īecause hypnograms represent sleep architecture, sporadic arousals from sleep are important factors contributing to sleep disorders or psychological conditions including irregular sleep-wake rhythm, insomnia, depression, narcolepsy, and sleep apnea. The diagram charts the relative progression of NREM sleep stages followed by REM deep sleep stages, using biofeedback covering four to five repeating sleep cycles to target sleep disturbances. The hypnogram at minimum includes sleep stage, body position, and Sao2 but may also chart the frequency of apnea, periodic limb movements, or other events. A hypnogram displays non-rapid eye movement (NREM) and rapid eye movement (REM) cycle fluctuations within a standard 90 to 120 minute time frame, marking sleep stages along a vertical axis (y-axis) while the horizontal axis (x-axis) represents a standard eight-hour duration of sleep.
