Screening and Treatment of SAHS in Patients With Acute Ischemic Stroke
Screening and Treatment of SAHS in Patients With Acute Ischemic Stroke
Ischemic stroke is a kind of common disease with great harm. In acute stage of stroke there
 is sharply increasing morbidity of sleep apnea hypopnea syndrome. Our suppose that treatment
 with noninvasive ventilation for patients with acute ischemic stroke should improve the
 functional prognosis（measuring with 90d modified Rankin score）.
In acute state of ischemic stroke，if patients with sleep apnea hypopnea syndrome may need
 additional respiratory management such bi-level positive airway pressure.We supposed the
 patients with stroke can take benefit of functional recovery form bi-level positive airway
 pressure. We choose the patients who suffered ischemic stroke in 48 hours ，then evaluate the
 respiratory status. Stroke patients who were diagnosed as sleep apnea hypopnea syndrome will
 accept additional treatment with bi-level positive airway pressure for 7 night（per night 6
 hours）.Then the modified Rankin scale score and NIHSS will be recorded at 30 days and 90 days
 after stroke.
