Estimated costs for respiratory management pre and post implantation and use of the Cough Stimulator. The actual costs of implantation are added to the costs of respiratory management in year 1. Total costs after year 1 were not significantly different compared to total costs pre implantation due to a significant reduction in the usual costs of respiratory management. Overall costs were significantly lower in years 2 and 3 during which subjects continued to use the Cough Stimulator (*p < .05 if compared to pre implant). See text for further explanation.
