Sleep-disordered Breathing in Children
Sleep is a major physiological drive. The average child spends almost one-half of his or her life asleep. A newborn will sleep for as much as 16 h a day. Thus, respiratory disorders during sleep are of particular importance during childhood. Although some respiratory disorders, such as sleep apnea, occur only during sleep, virtually all respiratory disorders—including upper airway obstruction, central hypoventilation, and chronic lung disease—are worse during sleep than wakefulness. It is therefore incumbent upon the pulmonologist to understand the effects of sleep upon bre ...
Clinical Evaluation of the GoodKnight 420E Auto-CPAP System for Treatment of Obstructive Sleep Apne
Since 1996, there have been technologies that allows automatic adjustment of continous positive airway pressure(CPAP) for treatment of obstructive sleep apnea syndrome(OSAS). There are many factors that influences overnight pressure needs in a given individual, including sleep structure, sleeping position, physiological changes in nasal resistance, and fluctuations in body weight.
Several parameters have been used to drive auto-adjusting CPAP,using either pressure or flow signals available inside the device that allow the detection of apneas, hypopneas, snoring, i ...
Day–Night Pattern of Sudden Death
background
The risk of sudden death from cardiac causes in the general population peaks from 6 a.m. to noon and has a nadir from midnight to 6 a.m. Obstructive sleep apnea is highly prevalent and associated with neurohormonal and electrophysiological abnormalities that may increase the risk of sudden death from cardiac causes, especially during sleep.
methods
We reviewed polysomnograms and the death certificates of 112 Minnesota residents who had undergone polysomnography and had died suddenly from cardiac causes between July 1987 an ...
