...all about NASAL HIGH FLOW

Who would benefit from Nasal High Flow?

  • Nasal High Flow (NHF) is not designed to treat snoring or obstructive sleep apnoea. It DOES help people who suffer from chronic breathlessness or chronic cough or dryness, not just at night time but even during the day. It is useful for people who suffer from any of a range of problems such as:

  • Chronic Obstructive Pulmonary Disease (COPD)
    Long-term oxygen therapy
    Chronic Bronchitis
    Sjogren's Syndrome
    Post radiotherapy

  • Because of our long experience providing sales and support of CPAP therapy in the community, Sleep Well Clinic have extended our clinical support systems to offer those same services to people using the Fisher & Paykel Healthcare myAIRVO 2 nasal high flow humidifier. If you can't breathe well, you can't sleep well either. So whether you use NHF during the day, or whether you use it to provide relief through the night, either way our phone-based clinical support team stand ready to help you get the most out of your therapy.


How does it work and how can I get it?

  • The myAIRVO 2 nasal high flow humidifier is especially designed to support every breath you take through the mechanical actions of increasing humidity, increasing airflow, and increasing pressure slightly. It can be used in isolation from other therapies such as medication or supplemental oxygen, or it can be used to support those therapies and make them more effective.

  • Call the Sleep Well Clinic to discuss how we can meet your particular needs the best. Most patients with daytime breathlessness will already be being treated through a hospital clinic or in conjunction with their GP. We can talk through how NHF therapy can compliment your existing treatments, or how it can be used as a potential alternative. We will work with your existing healthcare providers to ensure there is coherent continuity of care. For the myAIRVO 2, we have options for short or long-term lease, and also clincially supported sale options if NHF is an appropriate treatment for you.

  • Insomnia is affected by the three P's: predisposing factors, precipitating factors, and perpetuating factors. Daytime breathlessness and night-time cough can serve as any one of those factors. Many people who are exhausted during the day due to their respiratory difficulty also develop chronic insomnia. The Sleep Well Clinic is uniquely placed to help with both those problems through use of the myAIRVO 2 nasal high flow therapy system.

  • Insomnia is frequently a symptom of illness, severe stress, or a primary sleep disorder. Sleep Well Clinic provides a range of tests and comprehensive medical consultation to help decide which treatment is most likely to provide a long-term solution for you.

DR ALEX BARTLE and his team of health professionals at the SLEEP WELL CLINIC provide comprehensive assessment and treatment services throughout New Zealand for children and adults suffering sleep disorders such as SNORING, SLEEP APNOEA, INSOMNIA, and PARASOMNIAS.


  • Optimal humidity helps to hydrate phlegm and mucus, making it easier to clear.

  • Humidity also reduces congestion and bronchoconstriction.

  • Humidity aids muccociliary transport, the self-cleaning mechanism of the bronchi. Not only is mucus easier to shift because it is thinner and less sticky, the conveyor-belt system that takes it out of the lungs is actually working faster also.

  • Nasal High Flow (NHF) room air helps reduce deadspace in the airway.

  • This helps with clearance of expired air in the upper airways.

  • Nasal high flow therapy reduces rebreathing of gas with high carbon dioxide and depleted oxygen.

  • Alveolar ventilation is increased inside the lungs themselves, allowing better gas transfer between alveoli and the lung's blood supply.

    Positive Pressure

  • Nasal high flow therapy helps by supporting breath-and-flow-dependent pressure.

  • The dynamic positive airway pressure can also help during sleep by providing a small amount of airway support during the deeper stages of sleep when the muscles in the body all relax.

  • The dynamic positive pressure assists with alveolar ventilation by supporting the air sacs and helping hold them open longer for improved gas transfer.
