Treatment options for central sleep apnoea

It can be challenging to treat patients with CSA, who often experience fewer or different symptoms than OSA patients. Adaptive servo-ventilation, as delivered by the AirCurve 10 CS PaceWave, is an appropriate choice for treating most of these more complex patients.*

How prevalent is central sleep apnoea?


3.5% of obstructive sleep apnoea patients suffer from complex sleep apnoea (CompSA)1


Up to 45% of patients on opioids for chronic pain suffer from central sleep apnoea or complex sleep apnoea2


5 to 12% of ischemic and haemorrhagic stroke and transient ischemic attack patients suffer from primarily central apnoeas3

Central sleep apnoea treatment options

Continuous positive airway pressure or automatic positive airway pressure (CPAP/APAP) therapy is often used as the treatment of first intention, but experience shows that CPAP/APAP does not consistently control apnoeas or improve symptoms. As a result, some patients treated with CPAP/APAP remain symptomatic. This increases the risk of non-compliance and the likelihood that they will require multiple, resource-intensive interventions. 

Adaptive servo-ventilation* is often an appropriate choice for treating these more complex patients, either as a first intention therapy or after an unsuccessful trial with other positive airway pressure (PAP) therapies.  

Adaptive-servo ventilation: a proven solution for CSA

ASV is a form of PAP therapy that delivers auto-adjusting pressure support with automatic pressure support and expiratory positive airway pressure. ASV helps to treat both obstructive and central respiratory events and maintains adequate ventilation in response to patients’ changing needs.


Compared to other forms of PAP therapy, ASV offers significant benefits for the treatment of central sleep-disordered breathing.* This has been demonstrated in multiple clinical trials across various patient types.


* ASV therapy is contraindicated in patients with chronic, symptomatic heart failure (NYHA 2-4) with reduced left ventricular ejection fraction (LVEF ≤ 45%) and moderate to severe predominant central sleep apnoea.
