Adaptive servo ventilation (ASV)* and sleep apnea

    Category: Treatment & Therapy
    Topic: PAP Therapy & Adherence

    Research shows ASV* therapy delivers positive effects for the indicated population of patients with central sleep apnea (CSA) with additional benefits seen in specific patient groups.

    In the indicated patient population1-4

    Improved disease specific quality of life (QoL) based on SF 36† and Pichot Fatigue Scale

    In the indicated patient population1-4

    Reduced daytime sleepiness

    In addition to CSA, ASV*   treats obstructive sleep apnea (OSA) and treatment-emergent central sleep apnea (TECSA).

    Central sleep apnea (CSA)

    Prevalence:

    CSA

    Common symptoms: 6  
    • Insomnia
    • Poor quality of sleep
    • Sleep disturbances
    • Challenges concentrating
    • Morning headaches
    • Reduced ability to focus
    • Nocturnal angina
    • Paroxysmal nocturnal dispnoea

    Obstructive sleep apnea (OSA)

    Prevalence:

    OSA

    Common symptoms: 6  
    • Insomnia
    • Poor quality of sleep
    • Sleep disturbances
    • Mood changes
    • Cognitive deficits
    • Reduced ability to focus

    Treatment-emergent central sleep apnea (TESCA)

    Occurence:

    In patients with OSA when central apneas persist or emerge after obstructive events have been resolved by positive airway pressure (PAP therapy. In these patients, central events comprise more than 50% of remaining sleep disordered breathing events or lead to disruptive periodic breathing patterns.8-11  

    * ASV therapy should not be initiated in individuals with chronic and symptomatic heart failure (NYHA 2-4) with reduced LVEF≤45% and moderate-to-severe predominant CSA.
