Regular and enough good quality sleep is of vital importance to maintain healthy physical and mental health. Sleeping is like getting your body recharged for the next day. OSA (Obstructive sleep apnoea) is the commonest breathing disorder during sleep.Obstructive sleep apnoea is a repeated episodes of partial or complete collapse of the airways causing intermittent hypoxia during the sleep. This Leads to disruption of normal sleep resulting into excessive daytime sleepiness to compensate for the lost sleep in the night. It may also lead to variety of symptoms starting from morning headaches, reduced cognitive performance, resistant hypertension, vehicle accidents during one of the irresistible naps during driving. Sleep disordered breathing can be diagnosed with overnight polysomnography or sleep study.
Sleep study or polysomnography can be conducted either in hospital or at home. It is a non-invasive overnight examination which monitors thoracic and abdominal respiratory efforts, nasal flow, ECG, EEG, oxygen saturation and body movements throughout the sleep. It also has a microphone to record snoring. The data collected digitally in the overnight sleep is analysed by the sleep specialist next day. After analysis of data collected, sleep specialist can give a diagnosis of the type of sleep disordered breathing and guide treatment.
Moderate to severe severity of OSA can be treated with CPAP (Continuous positive Airway Pressure) device.
