Aktiv komparator: Standard NIV
Noninvasive ventilation (NIV) will be initiated and managed as per current standard of practice guided by the American Academy of Neurology (AAN) Practice Parameters (updated in 2009), in all subjects with amyotrophic lateral sclerosis (ALS) and a forced vital capacity of <50% predicted.
Sleep studies will be performed at baseline, 2 weeks, 1, 3 and 6 months, but will not influence management of the NIV.

NIV will be initiated and managed as per current standard of practice.
Sleep studies will be performed at baseline, 2 weeks, 1, 3 and 6 months to gather data but will not influence NIV management.
NIV will be adjusted by a respiratory therapist or the subject's primary physician per waking symptoms.

Eksperimentel: Sleep study titrated NIV
ALS subjects in this arm, who are offered NIV for Forced Vital Capacity (FVC) <50% as per AAN Practice Parameters, will have their initial level of NIV determined polysomnographically.
They will be followed with sleep studies at 1 month, 3 months and 6 months to reassess NIV efficacy and NIV will be adjusted as necessary to optimize parameters of oxygenation and ventilation.
|
Sleep studies will be performed at baseline, within 2 weeks to initially titrate NIV, and at 1, 3 and 6 months to assess NIV performance and adjust it as necessary based on oxygenation and ventilation parameters.
