For patients with positional OSA, we’re on your side


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

NightBalance Lunoa screen

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 optimise 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.

We're on your side with a sleep therapy that makes a difference

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.

Better sleep with NightBalance

NightBalance comfort

Exceptional comfort


  • Patients with positional OSA felt that mask-free NightBalance was more comfortable than PAP.1
  • Patients are prompted to change their sleeping position without disturbing their sleep.8
NightBalance adjustment

Easy adjustment


  • A built-in adaptation program helps patients gradually adjust to wearing and being treated by the device.
  • Patients with positional OSA felt that NightBalance was easier to adjust to than PAP therapy.1
NightBalance motivation

More motivation


  • NightBalance mobile app is designed to make treatment progress easy to see.

See how NightBalance is proven to make a difference

A survey following 75 NightBalance users for an average of 2.2 years reported impressive results.2

reported long-term improvement in the three most reported positional OSA symptoms


(non-refreshing sleep, fatigue, episode of breathing cessations, gasping, and/or choking during the night)

70 percent
reported feeling less sleepy during the day
reported feeling more refreshed during the day
72% fatigue during the day
reported feeling a decrease in fatigue during the day

How it works

Analysis and build-up phases


NightBalance begins by analysing sleep for the first two nights. It then gradually introduces gentle vibrations from night 3 to night 10 which are intended to acclimatise 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.
