“…The association between snoring and excessive daytime sleepiness has been identified previously in several studies performed in Western countries. 16 factors, and somatic and psychological complaints were associated with sleep problems. Ohida et al reported that unhealthy lifestyle-related factors such as lack of exercise and irregular eating habits, and also poor health status, were associated with short sleep duration and subjectively insufficient sleep.…”

BACKGROUND: Excessive daytime sleepiness is one of the principal symptoms of sleep disturbances, and is often associated with serious consequences including traffic and industrial accidents, decreased productivity, and interpersonal problems. However, there are few epidemiologic studies on excessive daytime sleepiness in a large scale sample targeting Japanese general population. METHODS: The survey was performed using a self-administered questionnaire in June 2000, targeting a population randomly selected from among 300 communities throughout Japan. This questionnaire included information about sleep habits and sleep problems. Excessive daytime sleepiness measured according to a question “Do you fall asleep when you must not sleep (for example when you are driving a car)?” RESULTS: A total of 28,714 subjects completed the questionnaire. The prevalence of excessive daytime sleepiness was 2.5% (male=2.8% and female=2.2%). Backward elimination analysis showed that the following were associated with excessive daytime sleepiness: male sex, young age, short sleep duration, subjective insufficient sleep, loss of deep sleep, disagreeable sensations in the legs, interruption of sleep by snoring or dyspnea, and feeling psychological stress. Interruption of sleep by snoring or dyspnea was the strongest associated factor (adjusted odds ratio=2.46, 95% confidence interval=1.76-3.43) of excessive daytime sleepiness. CONCLUSIONS: These results suggest that excessive daytime sleepiness in Japanese is associated with several sleep problems. These findings may be useful in attempts to prevent excessive daytime sleepiness in the general population of Japan.

“…2.3.3 Body movements Many attempts have been made to define the sleep/wakefulness cycle by measuring movement (Sadeh et al 1989;Vos and Stradling 1991;Webster et al 1982). Whilst these have been fairly successful, there are problems related to the sensitivity of such movement detectors, the part of the body upon which they are placed, and ignorance as to whether all forms of sleep disturbance and fragmentation lead to measurable body movement.…”

SUMMARY Our understanding of sleep-related breathing disorders is still in a period of rapid change. Considerable uncertainty exists in several major areas of patient assessment. Although early definitions of sleep apnoea enshrined the concept of rigid guidelines, such an approach is no longer helpful, and may constrain potential advances. The recognition of the basic pathophysiological events in obstructive sleep apnoea (OSA) has evolved from purely apnoeas, to include hypopnoeas, and now to increased upper airway resistance alone. Our view as to the significant consequences of such respiratory events has also evolved from alterations to the classic sleep architecture, to hypoxic events, and now to micro-arousals and cardio-vascular events. The exact nature of a significant arousal is also far from clear, with the suggestion that perhaps even EEG based approaches to their measurement may not be telling us the whole story. Finally, the frequency of such respiratory events and their consequences, that lead to significant symptoms and long-term damage, is not known either. Thus, given this situation, the best we can achieve is broad guidelines that stress the main important physiological events and their consequences that need to be assessed, and then interpreted in conjunction with the patient's symptoms. This will not necessarily be the same for all patients and this report offers some general guidance, based on the experience of several centres throughout Europe.

“…Lesser degrees of upper airway narrowing associated with snoring, increased inspiratory efforts and sleep fragmentation, may also result in decreases in daytime alertness [4][5][6]. It has even been suggested that there is a syndrome of increased upper airway resistance, causing increases in inspiratory effort and arousals from sleep, in the absence of either snoring or abnormal conventional sleep staging [7].…”

For convenience, it is usually measured from the R wave on the electrocardiogram to the pulse wave arrival at the finger. Pulse transit time is inversely proportional to blood pressure, and the falls in blood pressure which occur with inspiration (pulsus paradoxus) correspond to rises (lengthening) in pulse transit time. In awake normal subjects, the size of these inspiratory rises in pulse transit time correlate well with the degree of inspiratory effort. The aim of this study was to investigate whether inspiratory rises in pulse transit time could provide a quantitative measure of inspiratory effort in patients with obstructive sleep apnoea. Eight patients with obstructive sleep apnoea, attending the laboratory for institution of nasal continuous positive airway pressure, took part in the study. Once asleep, airway pressure was varied between optimal treatment level and minimum pressure, to produce a range of inspiratory efforts whilst continuous recordings of oesophageal pressure and pulse transit time were made.There was an excellent correlation between the size of the swings in oesophageal pressure and the size of the swings in pulse transit time (mean r=0.94).Pulse transit time may, therefore, provide a clinically useful noninvasive and quantitative measure of inspiratory effort in patients with sleep-related breathing disorders.
