Effectiveness of Compression Stocking on Overnight Fluid Shift in Obstructive Sleep Apnoea Patients

"A below-the-knee compression stock will be worn daily for 2 weeks from waking up to before sleep.~Bioelectrical impedance will be performed before and 2 weeks after wearing the stocking to assess the total body water content.~Measuring the calf and neck circumference will be done before and after wearing the compression stocking. After 2 weeks, the patient will return back to the clinic for calf and neck circumference measurement.~Sleep test will be done the night before and 2 weeks after wearing the compression stocking. Oxygen Desaturation Index(ODI) will be assessed through a level 4 home sleep apnea testing device.~Patients recruited will have mild excessive to severe excessive daytime sleepiness and/or STOP-Bang score of 3 or more, with underlying conditions such as type II diabetes and hypertensive patients using the Epworth sleepiness scale. Epworth sleepiness scale will be assessed again 2 weeks after to assess for increase sleep efficiency."
