About
The purpose of this study is to evaluate positive pressure in patients with chronic pain taking opioid medications who have sleep disordered breathing.
Full description
Purpose: Opioid treatment of non-malignant chronic pain can result in hypoxemia, hypercarbia, and central sleep apnea. The aim of this study was to determine the initial efficacy of auto servo-ventilation (ASV) and after 3 months of home use.
Methods: This prospective multicenter interventional study recruited chronic pain patients prescribed ≥100 morphine equivalents for at least 4 months.
Participants: Following full-night polysomnography (PSG) to confirm the presence of sleep-disordered breathing, patients were randomized to three additional full-night-attended PSGs with continuous positive airway pressure (CPAP), ASV, and servo-ventilation with an initial mandatory pressure support of 6 cm water (H2O) ASV manual Minimum Pressure Support (PSmin). Following the PSGs, patients were sent home with EncoreAnywhere and ASV with or without mandatory pressure support.
