ResMed’s solutions for chest wall disorders

ResMed is committed to improving the quality of life for patients with respiratory failure due to chest wall disorders through the use of home noninvasive ventilation (NIV) systems.

Non-invasive ventilation (NIV) is an effective treatment option for hypercapnic respiratory failure in patients with a chest wall disorder.1

ResMed’s Volume-Assurance mode, iVAPS (intelligent Volume-Assured Pressure Support) not only secures target volume but also alveolar ventilation by compensating for dead space ventilation. This is particularly important as patient conditions may change during the night; for example, respiratory drive is sometimes impaired during rapid eye movement (REM) sleep or when the patient moves to a supine position.

Some ResMed ventilators also feature NIV+ trigger technology that's sensitive enough that it can detect very weak breaths, triggering the ventilator to deliver the next breath for the patient so that breathing isn't delayed.

iVAPS is available in the following ResMed device used to treat respiratory failure associated with chest wall disorders:

Stellar™ 150

As an alternative, Astral™ 100 and Astral 150 can also be used for the treatment of respiratory failure associated with chest wall disorders, although these devices do not offer iVAPS.

Special considerations

Chest wall disorders are progressive and may require ventilator settings to be adjusted, based on how the patient's condition changes.

ResMed's range of ventilators caters to patients who are non-dependent as well as those who are dependent on ventilation. For extra versatility, ResMed ventilators offer both NIV and invasive options.

ResMed's advanced data collection capabilities (device and card data storage with high-resolution flow and pressure data, I:E ratio, synchronisation details, oximetry) and ResScan™ software provide clinicians with detailed data for troubleshooting and monitoring patient progress.

Factors limiting NIV treatment include leak, nasal problems and mask problems

ResMed's VSync algorithm ensures synchronisation when there is changing, and occasionally, large leak.

  • The TiControl™ feature allows clinicians to set a maximum value for time spent in inspiration (Ti Max), which ensures effective cycling to expiration when there is a large unintentional leak.
  • The leak data collected by the device and displayed in ResScan allows clinicians to accurately pinpoint and troubleshoot mask leak issues.
  • ResMed has developed highly effective integrated humidification systems which can deliver temperature and humidity-controlled therapy to patients, increasing comfort and compliance.
  • ResMed has a wide range of masks available to cover most patient types.
  • ResMed devices and masks are quiet and easy to use for both clinicians and patients.
Patients with chest wall deformities have low lung compliance (high elastance), which can lead to inspiration on a spontaneously-cycled ventilator ending too early.
  • ResMed's TiControl allows clinicians to set a minimum value for time spent in inspiration (available in the VPAP S, VPAP ST, Stellar 100 and Stellar 150).
  • In addition, ResMed ventilators can deliver the PAC mode (available in the Stellar 100, Stellar 150, VS III™ and Elisée™ 150).
