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.
