Nasal EPAP for Stroke Patients With Sleep Apnea: a Pilot Trial.

August 19, 2016 updated by: Devin Brown, University of Michigan

Specific aim: To test the effects of nasal expiratory positive airway pressure (EPAP) therapy on sleep apnea severity among patients with recent ischemic stroke.

Hypothesis 1: Ischemic stroke patients with sleep apnea will have less severe sleep apnea, as measured by the apnea-hypopnea index (AHI), with nasal EPAP therapy compared with a control night.

Hypothesis 2: Ischemic stroke patients will have higher mean levels of oxygen saturation with nasal EPAP therapy compared with a control night.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Apnea-hypopnea Index
Time Frame: night 1 and night 2
Apnea-hypopnea index (AHI) is the sum of the apneas and hypopneas and divided by the hours of sleep based on actigraphy. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and >= 30/h = severe. The prespecified primary (absolute) treatment effect is based on the linear repeated measures model.
