Frequently Asked Questions

CPAP and Sleep Apnoea

​

1. What is CPAP therapy?

CPAP (Continuous Positive Airway Pressure) therapy is a common treatment for obstructive sleep apnoea. It uses a machine to deliver constant airflow through a mask to keep your airway open while you sleep.

​

2. Do I need a prescription to purchase a CPAP machine?

In Australia, a doctor’s prescription is not legally required to purchase a CPAP machine. However, it is strongly recommended that CPAP therapy be guided by a medical professional to ensure appropriate treatment. Additionally, if you plan to claim through private health insurance, most providers will require a doctor’s note confirming that CPAP therapy is indicated.

​

3. Which CPAP machine is right for me?

This depends on your individual needs, prescription settings, and comfort preferences. If you’re unsure, contact us and our team can help guide you or refer you to a sleep specialist.

 

4. How do I choose the right CPAP mask?

Mask choice is personal and depends on your sleeping habits, facial structure, and comfort level. We stock nasal masks, nasal pillows, and full-face masks. Reach out if you’d like help selecting the right one.

5. How do I clean my CPAP machine and consumables?

Regular cleaning is essential to ensure your CPAP therapy remains hygienic and effective. Here's a basic guide:

• Daily: Wash your mask cushion and water chamber with warm water and mild soap. Rinse thoroughly and allow to air dry.

• Weekly: Clean your tubing, and headgear with warm soapy water. Rinse well and hang to dry completely before reconnecting.

• Do not use: Harsh detergents, bleach, or antibacterial wipes containing alcohol, as these can damage the equipment.

• General replacement guide:

  • Mask cushion: every 1–3 months (Memory foam cushion needs to be changed monthly)

  • Tubing: every 3–6 months

  • Filters: every 1–3 months (Humidx filter needs to be changed monthly)

  • Water chamber: every 6 months

 

6. Do I need to use distilled water in my CPAP humidifier?
A: Yes, it is highly recommended to use distilled water in your CPAP humidifier. Tap or filtered water contains minerals that can build up in the water chamber, leading to scaling, reduced humidifier efficiency, and possible damage over time. Distilled water helps maintain your machine’s performance and hygiene, and reduces the risk of inhaling mineral deposits or contaminants. Always empty and refill the water chamber daily to prevent bacterial growth.

​

7. How can I stop water from collecting in the CPAP tubing (rainout)?
A: Rainout happens when warm, moist air from the humidifier cools down in the tubing and forms condensation. To reduce or prevent rainout:

• Use heated tubing – This helps keep the air temperature consistent and reduces condensation.

• Adjust humidity and temperature settings – Lower the humidifier setting or increase the room temperature slightly.

• Position your CPAP machine lower than your bed – This allows water to drain back into the humidifier rather than pooling near your mask.

• Use a hose cover or insulating wrap – These help maintain the temperature of the air inside the tubing.

Managing rainout improves comfort and ensures uninterrupted CPAP therapy.

​

8. What are the alternatives if I can’t tolerate CPAP therapy?
A: While CPAP is the most effective treatment for moderate to severe obstructive sleep apnoea, not everyone finds it comfortable or easy to use. If you’re struggling with CPAP, talk to your sleep specialist — there are other options that may help, including:

​

• Mandibular advancement splints (oral appliances): These custom-made mouthguards hold your lower jaw slightly forward to keep your airway open while you sleep. They’re often suitable for people with mild to moderate sleep apnoea or those who snore heavily.

• Nasal EPAP (Expiratory Positive Airway Pressure) devices: These are small, disposable valves placed over the nostrils that create resistance when you breathe out, helping keep your airway open. They can be an option for mild to moderate sleep apnoea.

• Positional therapy: Some people only have sleep apnoea when sleeping on their back. Special pillows or wearable devices can help keep you sleeping on your side.

• Weight loss and lifestyle changes: Losing weight, avoiding alcohol before bed, and improving sleep posture can significantly reduce apnoea severity for some people.

• Surgery: In certain cases, surgery to remove excess tissue, correct nasal issues, or reposition the jaw can be an option.
