Philips NightBalance: Mask-free Solution for Obstructive Sleep Apnea

For many people, sleeping on their back -- called the “supine position” -- is the cause of Obstructive Sleep Apnea (OSA). When they sleep on their side, their breathing becomes normal again. Studies show that up to 47% of OSA patients have this type of OSA, called Positional OSA or POSA.

People with this condition can benefit from wearing a device that keeps them sleeping in the side position. Philips NightBalance is a clinically proven alternative to CPAP for this condition.  

What is Positional OSA?

Positional Obstructive Sleep Apnea (POSA) is a specific type of OSA. People with this condition have over twice as many sleep disturbances while sleeping on the back, compared to sleeping on the side. 

A sleep study can confirm whether you have POSA. SleepQuest provides an at-home sleep study that will diagnose POSA and other types of OSA. Our sleep experts will evaluate your test results to determine whether you have this specific type of OSA.

Is positional therapy right for me?

If you have POSA, you may have tried traditional Continuous Airway Pressure (CPAP) treatment. If you find the mask uncomfortable, you might want to try positional therapy. 

What is NightBalance?

NightBalance is a small palm-sized device that you wear across your chest, with a soft adjustable strap. The device will deliver gentle vibrations that prompt your body to shift to the side position -- without waking you up. 

How does NightBalance work?

When you go to bed, you can fall asleep in any position. NightBalance will detect when you are on your back and send a gentle vibration which prompts your body to change positions. This won’t disturb your sleep. Through the night, NightBalance will automatically adjust the vibration intensity to ensure you get into the side-sleeping position.

The quiet vibrations help keep you off your back, so you don’t have the high number of sleep disturbances that typically occur.

How can I get NightBalance?

Your will need a prescription from your doctor that includes a diagnosis of sleep apnea. Your sleep study will confirm the diagnosis of OSA, and your doctor can also confirm the diagnosis of positional OSA. Your prescription doesn’t need to mention NightBalance. A prescription for CPAP is not valid.

We can also reach out to your physician on your behalf, if you request it. You can also send a request to this email address: -- and they will follow up with you/your doctor to obtain the prescription.
