Central Sleep Apnoea (CSA) is a type of sleep-disordered breathing. Unlike Obstructive Sleep Apnoea (OSA) patients who have partially or fully blocked upper airways that restrict breathing, patients with CSA have a lack of respiratory drive. This means either the breathing centre in the brain fails to trigger breathing, or the signal to inhale is not transmitted properly to the rest of the patient’s body.
It can be challenging to treat patients with CSA, who often experience less or different symptoms than OSA patients. Adaptive servo-ventilation (ASV)* featured in AirCurveTM 10 CS PaceWaveTM is an appropriate choice for treating most of these more complex patients.
* 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.
