Autotitration or Automatic Positive Airway Pressure (APAP) devices
- Are positive airway pressure devices used in the treatment of Obstructive Sleep Apnoea (OSA)
- Automatically adjust, on a breath by breath basis, to blow the minimum pressure needed to keep your airway open during sleep. This allows your machine to provide you with your ideal pressure over the entire night.
- Tend to be more advanced, more feature rich and more expensive than CPAP machines.
- May also be known as:
- Auto Adjusting CPAP
- Auto Titrating CPAP
- Self Adjusting CPAP
- Auto PAP
- Automatic CPAP
- Auto
Our AutoSet™ Technology

Third-party clinical trials have found that our AutoSet™ devices prevent more apnoeas and hypopnoeas and operate at lower average pressures than fixed pressure devices. Lower pressure means greater comfort for you.
Most devices only adjust pressure after an event (an apnoea, hypopnoea, or snore) has occurred, but AutoSet devices actually prevent most events.
AutoSet devices respond preemptively to apnoeas and hypopnoeas by monitoring the user's inspiratory flow-time curve. Changes in this curve indicate the likely occurrence of an apnoea, hypopnoea, or snore.
Some apnoeas will occur without any precursor, and in these situations, the AutoSet device responds to the severity of the apnoea, not providing too much additional pressure and not providing too little - as in devices with arbitrary incremental increases.

Are all Autotitration devices the same?
No. Although these machines use complex algorithms, each manufacturer's device uses a different--usually patented--algorithm that responds to different signs of snoring, flow limitation, hypopnoeas, and apnoeas.
The algorithm largely determines the quality and comfort of treatment, so if you are prescribed an autotitration system, please check with the manufacturer to see that the device has been clinically validated to provide the treatment it promises.
