Summary  Until recently, obstructive sleep apnoea was a largely unknown condition. Because of the well-publicised death of some high-profile people resulting from untreated obstructive sleep apnoea, now mostly everyone has heard of the condition. Following diagnosis, several medical treatment modalities are available to patients. However, the role that dentistry and ...

BACKGROUND: Most patients with obstructive sleep apnoea (OSA) do not tolerate treatment with nasal continuous positive airway pressure, the 'gold standard' treatment for this condition. It was shown in a pilot study that acupuncture was more effective than placebo treatment (sham acupuncture) in producing significant changes in the respiratory events ...

A brief discussion of the objective measurement of sleep-disordered breathing, largely in the form of overnight monitoring, is undertaken.

BACKGROUND: In children both nasal pressure (NP) and thermistor (Th) technologies are commonly used to assess airflow measurement during routine polysomnography (PSG) for the assessment of sleep disordered breathing. We aimed to compare NP and Th measurement techniques when scoring central and obstructive respiratory events during PSG. METHODS: Sleep, arousal ...

Sleep is an essential part of our daily living, and sleep disturbances may intervene with the biological and physiological processes in human body leading to the development of metabolic dysfunction. Short sleep duration and poor sleep quality have adverse effects on metabolism and hormonal processes, contributing to increased cardiovascular risk. ...

A plethora of medical consequences have been associated with the syndrome of obstructive sleep apnoea (OSA). These are global, affecting nearly every body function, and have been related to two key pathophysiological findings in sleep apnoea: repetitive falls in oxyhaemoglobin saturation during sleep, and recurrent arousals from sleep which terminate ...

Obstructive sleep apnoea (OSA) is increasingly being recognized as an important health issue in the last two to three decades. It is characterized by frequent episodes of upper airway collapse during sleep, causing recurrent arousals, intermittent hypoxaemia, sleep fragmentation and poor sleep quality. There is accumulating evidence that OSA is ...

Obstructive sleep apnoea (OSA) is a prevalent disorder with significant co-morbidities. Presently only rarely, treatments for obstructive sleep apnoea are curative. More typically, this is a disease that requires lifelong intervention and commitment from both the patients and healthcare providers. In light of the commitments, there is no uniform approach ...

Central sleep apnoea (CSA) is characterized by the cessation of breathing during sleep due to absent ventilatory drive and may be associated with symptoms of insomnia, excessive daytime sleepiness or frequent arousals. Central apnoeas occur through two pathophysiologic patterns, either post- hyperventilation or post-hypoventilation. The prevalence of CSA is dependent ...
