Description of Medical ServiceThe proposed medical service is a Home Sleep Apnoea Test (HSAT). The HSAT measures seven channels: peripheral arterial tone (PAT) signal, oximetry, actigraphy, heart rate, body position, snoring, and chest movement. By using these seven channels, the PAT HSAT can differentiate between sleep periods and awake time periods, which allows the analysis of 'true sleep time', and can report sleep stages (light, deep, and rapid eye movement sleep), apnea hypopnea index, oxygen desaturation index, and other major indices necessary for the diagnosis of obstructive sleep apnoea.
Description of Medical ConditionSleep apnoea is a common sleep-related breathing disorder. The most prevalent type of sleep apnoea is obstructive aleep apnoea (OSA), which is characterized by a narrowing of the upper airway that impairs normal ventilation during sleep , resulting in repeated reversible blood oxygen desaturation and fragmented sleep. OSA has been associated with a range of pathophysiological changes that impair cardiovascular function, including increased blood inflammatory markers and repeated rises in blood pressure . OSA is strongly linked to a variety of health problems such as coronary heart disease, stroke, atrial fibrillation, diabetes, hypertension and greater mortality risk.
