Night-to-night variability of sleep activity requires more home-based portable sleep monitoring instead of clinical polysomnography examination in the laboratory. In this article, a wireless sleep activity monitoring system is described. The system is light and small for the user. Sleep postures, such as supine or left/right side, were observed by a signal from a tri-axis accelerometer. An overnight electrocardiogram was also recorded with a single lead. Using an MSP430 as microcontroller, both…

The role of portable monitoring is evolving but at this time cannot substitute for attended polysomnography as a standalone approach and the cost-benefit depends on local circumstances and cannot be generalized.

Cardiorespiratory-based sleep staging in subjects with obstructive sleep apnea

It is concluded that the cardiorespiratory signals provide moderate sleep-staging accuracy, however, features exhibit significant subject dependence which presents potential limits to the use of these signals in a general subject-independent sleep staging system.
