• CPAP is first line treatment for CSA
• CPAP can improve PCO2 slightly by helping VQ mismatch and reducing LV afterload
  • CPAP improves LV afterload by preventing upper airway collapse
• CPAP does not improve survival benefit in heart failure patients.
  • CANPAP trial CPAP does not improve mortality for patients with central sleep apnea and HFrEF?

Bipap

• it's unclear whether bipap is effective
• up to 20% of OSA pts starting on CPAP can also be found to have underlying central events in the first 3 months

ASV

• adjusts each breath pressure levels
• can increase PS during apnea and hyponea; can also decrease PS during hyperventilation¹
