Summary

Overnight rostral fluid shift is one of the contributing factors for worsening obstructive sleep apnoea (OSA). Fluid shift has been recognized to play a role in the pathophysiology of sleep apnoea. Previous studies shown that fluid from the leg redistributes to the neck at night increases the neck circumference, hence indicating fluid accumulation in the neck. OSA patients are more susceptible to developing upper airway narrowing in response to fluid shift from the leg to the head and neck region.

Previous studies were mainly done on Caucasian patients. The pathophysiology of OSA in Caucasian patients and Asian patients are different but both suffer a similar degree of OSA. The investigators would like to investigate if reducing leg swelling by a simple non-invasive intervention of wearing compression stocking during the day can attenuate sleep apnoea, and whether compression stocking is generally acceptable and well-tolerated among the general OSA population in Asia.

Conditions

Interventions

DEVICE

Compression stocking

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.
