Sleep Apnea
Conditions
Brief summary
To study whether Somfit is substantially equivalent to an existing approved device (i.e. Compumedic's Grael System) to assist in elucidating sleep disorders.
Detailed description
Sleep is recognized as one of the three pillars of health (i.e. nutrition, exercise and sleep). Poor quality and fragmented sleep leads to an increase in the risk for development of chronic health conditions. Given the importance of good quality sleep and its critical role in overall well-being, there is a need for regular monitoring and assessment of sleep quality in individuals. However, current technologies will only allow for this to be performed in sleep clinics and with the help of full polysomnography (PSG) systems which require the patients to spend a night at the clinic with several wired electrodes connected to their scalp. This will cause discomfort for the patients in a long run. To solve this problem, Compumedics has recently developed a miniaturized, portable and affordable sleep monitoring system with code name of Somfit which can be used in the comfort of patients' home. The aim of this study is to validate Somfit for home based sleep studies.
Interventions
DEVICEIntervention is the validation of a sleep monitoring device (i.e. Somfit) against the gold-standard polysomnograph with electroencephalograph (i.e. the Greal system)
Data were recorded overnight by both devices simultaneously
