Resmed reports that OSA patients who develop central sleep apnea may be more likely to comply with ASV therapy than CPAP. 

The study analyzed anonymous, aggregated data from the devices of 198,890 telemonitored patients in the United States who were receiving positive airway pressure therapy for their sleep apnea. It showed that those with treatment-emergent CSA who switched from CPAP to ASV used their therapy longer and had significantly fewer apneas (breathing stoppages or reductions) during sleep:

  • 62.7 percent: Patients’ compliance on CPAP prior to switching
  • 76.6 percent: The same patients’ compliance after switching to ASV

“Achieving compliance through proper therapy usage is a well-recognized clinical goal in sleep apnea management, and one that is often hard to achieve, particularly in difficult-to-treat patients who may have untreated central sleep apnea,” said Carlos Nunez, M.D., ResMed’s Chief Medical Officer. “These findings underscore the importance of continuously monitoring central sleep apnea and rethinking the conventional wisdom on therapeutic options based on each patient’s disease severity.”
