Adaptive Servo-ventilation Monitoring Study

Completed
Conditions
Chronic Heart Failure
Registration Number
NCT02133859
Lead Sponsor
ResMed
Brief Summary

Sleep disordered breathing is very common in patients with chronic heart failure with reported prevalence rates of 50-75%. Adaptive Servo-Ventilation (ASV) can be used to treat sleep apnea in these patients. This is an observational study to document changes in respiratory parameters in HF patients using ASV for a period of 12 months.
