Summary

Central sleep apnea (CSA) is common in patients with heart failure and those using opioid analgesics. Unfortunately, effective treatment of central apnea remains elusive, pressure therapy given the modest efficiency of positive airway pressure therapy. The focus of this proposal is to identify mechanistic pathways to guide future therapeutic interventions for central sleep apnea based on the strong premise that multi-modality therapy will normalize respiration and hence mitigate adverse long-term consequences of CSA. The investigators' proposed studies will test combination therapies, including positive airway pressure (PAP) plus a pharmacological agent who have heart failure or are using opioid analgesics. The investigators anticipate that findings will inform future clinical trials to improve care and quality of life among Veterans suffering from central sleep apnea, which remains difficult to treat using existing approaches.

Conditions

  • Sleep Disordered Breathing
  • Able Bodied

Interventions

DRUG

Trazodone + PAP therapy

The central apnea index and the apneic threshold will be compared under two conditions: trazodone or placebo. In addition, participants will get PAP therapy during both the conditions.

DRUG

Oxygen + PAP therapy

The central apnea index and the apneic threshold will be compared under two conditions: oxygen or room air. In addition, participants will get PAP therapy during both the conditions.
