Residual Sleep-Related Respiratory Events During Early Versus Long-Term NIV Follow-Up: Burden and Relationship with Gas Exchange

Background

A recent study published by our group demonstrated that patient–ventilator asynchrony (PVA) is independently associated with impaired gas exchange during long-term non-invasive ventilation (NIV). We aimed to determine whether the burden and phenotype of residual PVA vary according to disease category, NIV initiation context and follow-up timing, and whether the relationship between PVA and gas exchange differs according to follow-up timing.
