Stanchina's team identified a study sample of 3,396 patients from 2007-2010 who had COPD or OSA.
This sample included 227 overlap syndrome patients who had both COPD and OSA.
The Infinity cushion has variable thickness, thus offering even more comfort but also maximum stability.
Thanks to the highly flexible headgear and the silicone Infinty Seal cushion, the mask follows naturally head movement.
It involves repetitive episodes of complete or partial upper airway obstruction occurring during sleep despite an ongoing effort to breathe.
The most effective treatment option for OSA is CPAP therapy, which helps keep the airway open by providing a stream of air through a mask that is worn during sleep.
All patients in the overlap group were treated with CPAP therapy, and objective treatment compliance data were collected for the first one to three months of use. Multivariate analysis revealed that hours of CPAP use at night is an independent predictor of mortality (hazard ratio = 0.71) in patients with COPD and OSA.
Results show that overlap syndrome patients who use CPAP have a significantly higher survival than those who do not.
