Philips NightBalance We’re on your side

    fantasy banner image

    NightBalance is a clinically proven positional obstructive sleep apnea (OSA) therapy that’s mask free and easy for your patients to use.


    Studies have demonstrated greater adherence and similar efficacy in long-term symptom improvement compared with that of PAP therapy.1,2 Built-in support tools, such as a portal and mobile app, help give you the confidence of knowing your patients are getting better sleep on their side.

    Take a closer look at positional OSA

    Defining positional OSA

    POSA prevalence

    Positional OSA has been identified in many patients with OSA5


    Positional OSA is a specific diagnosis in which the vast majority of apneic events occur during supine sleep.3 Positional OSA is diagnosed from any sleep study in which body position is measured. 47% of OSA patients may have exclusive positional OSA.4

    Cartwright criteria uses the following to define and diagnose positional OSA3

    AHIsupine ≥ 2 x AHInon-supine

    Challenges and opportunities  in treating positional OSA

    Nonadherence with PAP therapies ranges from
    29% - 83%

    Addressing challenges with many available therapies


    CPAP non-adherence ranges between 29-83%, when non-adherence is defined as a mean of less than or equal to 4 hours of use per night.6,7

    An opportunity to optimize therapy

    Targeted positional OSA therapy


    Traditional sleep therapies used for OSA are also typically used to treat positional OSA, despite the availability of less invasive, validated treatments that target positional sleep apnea.

    Data-driven results


    Available therapies for positional OSA lack data feedback that allow for tracking treatment progress.

    Proven efficacy icon

    Proven efficacy


    The AHI during PSG on NightBalance was not importantly different from a clinical perspective to that on PAP therapy.1


    The effectiveness of NightBalance and auto-adjusting positive airway pressure was similar across the categories of AHI severity.

    Greater adherence icon

    Significantly higher adherence


    Adherence with NightBalance was significantly higher than with PAP in patients diagnosed with positional OSA.1

    Data driven results icon

    Data-driven results


    Adherence and positional sleep data is accessible to you via a streaming, cloud-based system.

    Backed by clinical evidence

    NightBalance is supported by years of clinical studies in patients with positional OSA.

    How it works

    Analysis and build-up phases


    NightBalance begins by analyzing sleep for the first two nights. It then gradually introduces gentle vibrations from night 3 through night 10 which are intended to acclimate the patient to the NightBalance device. Full therapy begins on night 10.

    Nightly use

    illustration showing sitting with NightBalance

    Patient can fall asleep in any position. After 15 minutes, the device activates and begins monitoring.

    Illustration showing patient on their back wearing NightBalance

    NightBalance detects when the patient is on their back. It prompts the patient to move off their back without disturbing their sleep.

    Illustration showing rolling over with NightBalance

    Vibrations will stop when patient is on their side.
