NightBalance is a compact, easy-to-use, mask-free treatment for positional OSA. The palm-sized device is worn comfortably across your chest in a soft, adjustable strap. NightBalance delivers gentle vibrations that prompt you to shift to your side without disturbing your sleep. It automatically adjusts the intensity of vibrations to provide the therapy you need.

More than 70% of people using NightBalance reported a long-term improvement in the three most reported positional OSA symptoms, including:2






Positional OSA is different than OSA. With positional OSA, most symptoms, like interrupted breathing, occur when you sleep on your back. If your sleep study reveals you have positional OSA, talk to your doctor about NightBalance.

Getting the most out of your device
For the first 2 nights, the device monitors your sleeping behavior with no therapy.
During nights 3-9, vibrations are gradually introduced over time to allow you to acclimate to the new POSA therapy.
On day 10 and forward, full treatment is delivered when therapy is needed – reducing the time spent sleeping on your back.5


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

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

Vibrations will stop when patient is on their side.
NightBalance is supported by an our medical advisory board, comprised of distinguished world renowned scientists and clinicians.
