Overview
Brief Summary
Quality of sleep is profoundly affected in patients with hypercapnic respiratory failure and restrictive disorders, with a decrease in rapid eye movement (REM) and slow wave sleep, and an increase in sleep fragmentation. Assisted ventilation aims at improving blood gases, but may also have a favorable impact on sleep structure. The investigators reviewed polysomnographic and blood gas data obtained between 1987 and 2008 in 95 patients with restrictive pulmonary disorders, before and after implementing non-invasive ventilatory support.
Detailed Description
Chart review of all patients with predominantly restrictive pulmonary disorders treated for respiratory failure by NIV at our institution between 1987 and 2008. Data systematically recorded included pulmonary function tests, diurnal arterial blood gases, and polysomnography before and after implementation of nocturnal NIV.
