An independent survey was conducted with positive airway pressure patients from the United States, United Kingdom, Germany, France and Australia, including patients who have used more than one different brand of positive airway pressure mask. The survey was conducted by a third party, DVL Smith, at ResMed’s request and expense. Based on the collective survey results, of those expressing a preference, the data demonstrates, at the 95% confidence level, that ResMed is the preferred mask brand. The detailed results of the survey are proprietary to ResMed. This survey was conducted between August 14 and September 6, 2012.
