CPAP Machines

Obstructive Sleep Apnea (OSA) is a common sleep disorder that is characterised by snoring and choking when sleeping, and excessive daytime sleepiness when awake. In recent years, it has gained considerably more attention by doctors and the public at large, due to its relationship to more serious health complications, such as heart disease, stroke, type 2 diabetes, hypertension, stroke, cancer and depression.

One of the primary treatments for Obstructive Sleep Apnea is CPAP, otherwise known as Continuous Positive Airway Pressure.

What is a CPAP machine and how does it work?

Continuous Positive Airway Pressure (CPAP) machine is a medical device used primarily to treat Obstructive Sleep Apnea (OSA). By wearing a CPAP mask, which attaches via a tube to the CPAP machine, gentle air pressure is delivered into the patient’s airways (throat area), operating as a “splint”, to keep the airways open and preventing snoring and choking when sleeping. Used regularly, CPAP machines can significantly improve a patient’s sleep quality and reduce the risk of related health complications. CPAP machines come in 3 types:

  1. Fixed Pressure CPAP (otherwise known as CPAP);
  2. Automatic CPAP (otherwise known as APAP); and
  3. BiPAP (otherwise known as Bi-level, VPAP or medical ventilation).



Fixed Pressure CPAP
Fixed Pressure CPAP machines work by delivering a constant air pressure when the patient sleeps.
The constant pressure is determined during an overnight sleep study where an optimal pressure is determined to keep the airways open.

Automatic CPAP (APAP)
Automatic CPAP machines, commonly referred to as APAP, Variable Pressure CPAP or smart CPAP, is a more advanced CPAP machine, that automatically adjusts the pressure on a breath-by-breath basis. This CPAP machine was invented primarily with the purpose of improving patient compliance and comfort with CPAP treatment. Optimal therapy is achieved by automatically providing the patient with the minimum pressure required to maintain an unobstructed airway on a breath-by-breath basis.

Bi-Level CPAP
BiLevel CPAP, also known as BiPAP, VPAP or medical ventilation) is designed primarily to treat Central Sleep Apnea, Complex Sleep Apnea, or those with coexisting respiratory or cardiovascular disorders.

It works differently from Fixed Pressure CPAP and Automatic CPAP, by providing two different levels of air pressure. There is a higher pressure when breathing in (Inspiratory Positive Airway Pressure or IPAP) and a lower pressure when breathing out (Expiratory Positive Airway Pressure or EPAP). By reducing the pressure during exhalation, patients often report feeling more comfortable, especially for those on higher pressures.

CPAP is used for Obstructive Sleep Apnea treatment. ALWAYS FOLLOW THE DIRECTIONS FOR USE. When considering whether CPAP is right for you, speak to your doctor.

Frequently Asked Questions

What are the main components of a CPAP machine?

The primary components of a CPAP machine are:

  1. CPAP machine – CPAP stands for “Continuous Positive Airway Pressure” and it is a device that blows gentle air pressure into a person’s upper airways (i.e. throat area), via a CPAP mask to keep their upper airways open and to prevent it from collapsing.

  2. CPAP Tubing – This connects the CPAP machine to the CPAP mask, allowing the flow of pressurised air from the machine to reach the user’s airways.

  3. CPAP Mask – This is the component that connects the machine to the user. CPAP masks are usually categorised into 3 CPAP mask types:

    a. Full Face CPAP Mask - covers the nose and mouth

    b. Nasal CPAP Mask - covers just the nose; and

    c. Nasal Pillow CPAP Mask - sits underneath the nose.

How do I prevent mask leaks while using a CPAP machine?

Mask leaks in CPAP usage refer to the escape of excessive air from the mask. It is often noticeable by a loud hissing sound. These leaks can typically be prevented through the correct use and choice of the mask.

To avoid mask leaks:

  1. CPAP Mask fit – incorrect application of the CPAP mask can lead to leaks. Follow the CPAP machine’s instructions to make sure the mask cushion is properly oriented and that you’re wearing the mask as intended.

  2. CPAP Mask size – check that you have the right CPAP mask size. If unsure, speak to your CPAP Consultant or Sleep Physician for assistance.. The mask should comfortably cover the necessary areas without being overly tight or loose. It’s crucial that the mask’s pillow or nasal prongs sit snugly against your face, and the headgear should be secure but not constricting.

  3. Mask type - different mask types (ie full face, nasal and nasal pillow) suit different patients better than others. For example, if you mouth breathe, you may find that a full face mask is more comfortable.

  4. CPAP Mask age- your CPAP mask will generally deteriorate over time, affecting the seal and comfort of the mask. The usual lifespan of a CPAP mask is 1 year.

  5. Regular Maintenance – regular cleaning is essential to prevent leaks due to material deterioration or buildup of oils and dirt. Clean the mask cushion or nasal pillows daily and the entire mask weekly with warm water and dishwashing liquid.

  6. Consultation – if you’re uncertain about the best mask type for you, consult with an experienced CPAP Consultant or Sleep Physician. They can offer guidance on the different masks available and help you find one that suits your specific needs.

What should I do if I experience discomfort while using a CPAP machine?

It’s essential to address the possible cause of discomfort to ensure your treatment remains effective and comfortable.

A common source of discomfort is the feeling of bulkiness or restrictiveness from wearing a CPAP Mask. To avoid this, you should consider discussing alternative CPAP Mask options with your CPAP Consultant or Sleep Physician. There are various types of CPAP Masks available, and finding one that suits your comfort preferences can significantly improve your experience.

Additionally, you may consider using special CPAP pillows designed to enhance comfort while sleeping with a CPAP Mask. These pillows often have cut-outs on the sides to accommodate the CPAP Mask and CPAP Tubing, reducing pressure on your face and helping to maintain a proper seal throughout the night.

How do I know if my CPAP machine needs calibration or adjustment?

If you experience continued difficulties with either your CPAP machine or CPAP mask, speak to a Sleep Physician, as your CPAP machine pressure may require adjustment or there may be other underlying issues that should be assessed.

Signs that your CPAP machine settings may be suboptimal include continuous fatigue, loud snoring, frequent mask leaks, and difficulty exhaling.

Under these circumstances, it is crucial to contact your doctor or CPAC Consultant. Adjusting the settings of a CPAP machine should be done under supervision to ensure the therapy remains effective and safe for your specific needs.

Can Sove CPAP Clinic help me troubleshoot common CPAP machine issues?

Sove CPAP Clinic has a comprehensive clinical team including Respiratory & Sleep Physicians, Cardiologist, Sleep Technologists and CPAP Consultants that offer face-to-face and telehealth consultations.

How often should I replace parts of my CPAP machine?

Generally, it is recommended that CPAP masks and their parts be replaced every six to twelve months. However, the exact timing can differ based on the type of part and individual usage.

For instance, the replacement schedule for the filters in your CPAP machine can vary based on the type of filter used, the quality of the surrounding air, and environmental factors such as whether you have carpet or pets at home.

That said, it’s critical to adhere to the manufacturer’s guidelines for replacing your mask and accessories.

What is the best way to monitor my progress with CPAP therapy?

Some CPAP machines come equipped with the capability to track your therapy progress. However, consulting with your Sleep Physician and CPAP Consultant is key to a comprehensive understanding and management of your treatment.

Services like those offered by the Sove CPAP Clinic, in partnership with Centurion Healthcare, provide specialist consultations and sleep studies. You can reach out to us regarding a detailed evaluation of your sleep health and the effectiveness of your CPAP treatment.

Can CPAP machines be used during pregnancy?

It is always important before commencing CPAP treatment, to speak with your doctor first, who will determine your suitability for CPAP treatment.

Assuming your doctor has recommended CPAP treatment, CPAP can most certainly be used during pregnancy, and clinical studies have found that CPAP treatment has clinical benefits particularly for expecting mothers with preeclampsia (i.e. high blood pressure during pregnancy).

Are CPAP machines loud?

The level of noise can vary depending on the model and age of the CPAP machine. However, most modern CPAP machines are designed to be very quiet, making them less likely to disturb sleep.

If you find that your CPAP machine’s noise is louder than expected, it could be due to a dirty or blocked air filter. Ensuring that the unit’s components are clean can help reduce any unwanted noise and improve the overall functioning of the machine.

Can you skip a night of CPAP?

While missing a single night might not pose a significant health risk, it is possible you might experience similar symptoms as you did before you started using a CPAP machine. These may include morning headaches, tiredness, and moodiness, but the severity could vary from person to person. Continuous use is crucial for maintaining the benefits of CPAP and preventing the return of sleep apnea symptoms.

Speak to your doctor before discontinuing CPAP usage at any stage and irrespective of time duration.

How do I know if my CPAP treatment is working?

To determine if your CPAP treatment is effective, you may notice the following signs: feeling more rested during the day, fewer morning headaches, improved focus on tasks, decreased snoring, fewer interruptions while sleeping, the absence of gasping for breath upon waking, and more continuous breathing while sleeping.

These improvements may indicate that your CPAP therapy is likely working as intended. However, for a comprehensive assessment, it is best to consult with a doctor or CPAP Consultant. They can provide professional insight and monitor your treatment progress accurately.

CPAP is used for Obstructive Sleep Apnoea treatment. ALWAYS FOLLOW THE DIRECTIONS FOR USE. When considering whether CPAP is right for you, speak to your doctor.

Is a prescription required to purchase a CPAP machine?

A prescription is not required to purchase a CPAP machine, however, it is strongly recommended that CPAP treatment is managed under the supervision of a doctor or CPAP Consultant.

How do I know which CPAP mask suits me?

It is best to commence CPAP treatment under the supervision of your doctor and/or CPAP Consultant, as they will be in a better position to advise you on the best masks available for you, taking into account factors such as:

  1. Breathing style – do you breathe through your nose and/or mouth?

  2. Skin sensitivity;

  3. Personal comfort;

  4. Mask fit as high air leakage is undesirable;

  5. Claustrophobia or anxiety;

  6. Facial hair;

  7. Lifestyle habits – do you watch TV, read or wear glasses before sleep? As a mask that obstructs your field of vision may be important.

Are there different types of CPAP masks and sizes?

Yes. There are many different types of CPAP masks and sizes. CPAP masks are generally classified as:

  1. Full face masks

  2. Nasal masks

  3. Nasal pillow masks

There are also many different CPAP manufacturers. The most popular brands include ResMed, Philips and Fisher & Paykel.

It is important to speak to either your doctor or CPAP Consultant to help you choose the best mask for you. Note also, that while most masks will be compatible with most CPAP machines, there are some CPAP machines that are only compatible with a selection of CPAP masks. Again, best to speak with your doctor or CPAP Consultant who can advise you best about this.

How long does it take to get used to using a CPAP machine?

Getting used to using a CPAP machine varies from individual to individual. Factors that can affect this time frame include:

  1. Expectations – understanding that getting used to using a CPAP machine can take time is important in setting the right patient expectations. Generally, we expect to see a “J-curve” effect, where patients will generally feel worse, before they feel better.

  2. Persistence – it is important that the patient maintains an open mind to being on a CPAP machine and understands the importance of treating Obstructive Sleep Apnea.

  3. CPAP mask choice – choosing the right mask is important for comfort, seal and effective therapy. A poor fitting and uncomfortable CPAP mask can derail a patient’s CPAP machine experience quickly.

  4. CPAP machine pressure settings – setting the patient’s CPAP machine pressure settings is imperative for effective therapy and comfort. The CPAP ramp and minimum pressure settings are important to manually calibrate to ensure the patient can breathe comfortably when they first go to bed. If the patient suffers from nasal congestion, the patient will generally require a higher minimum pressure setting to breathe comfortably.

  5. Consistent CPAP machine use – Consistency is key to acclimatising to CPAP treatment effectively. The more the CPAP machine is used, the faster the body adapts to CPAP therapy.

  6. Education – the better educated the patient is on the importance of CPAP therapy and the benefits it can provide in terms of sleep quality (for the patient and bed partner) and overall health, the more motivated the patient will be to use their CPAP machine.

  7. Clinical support – having the right CPAP support is critical to successfully acclimatising to CPAP treatment.

What support does Sove CPAP Clinic provide its CPAP customers?

Patient care and support is paramount at Sove CPAP Clinic. Our support includes:

  1. Face-to-face consultations at our brick-and-mortar clinics nationwide;

  2. Telehealth consultations (Video conferencing)

  3. Over-the-phone consultations

Why do I need a humidifier with my CPAP machine?

A humidifier is commonly integrated with most CPAP machines. Its purpose is to deliver moisture to the user’s nose, mouth and airway during sleep. The benefits of humidification include:

  1. Reducing dryness – the airflow from a CPAP machine without humidification can often dry out a patient’s nose, mouth and throat, leading to discomfort, irritation and congestion. By adding moisture to the air, these issues are reduced, and users can breathe easier.

  2. Reducing nasal and throat irritation – dry air can cause the nasal passages and throat to be inflamed and irritated. Particularly if the patient has allergies, a cold or other respiratory conditions. Humidification improves this.

  3. Improved comfort – moisture can improve a patient’s overall sleep quality and CPAP machine compliance.

  4. Reducing nosebleeds and sinus congestion – dry air can increase the likelihood of a nosebleed and sinus congestion. Humidification improves this.

Use of a humidifier with your CPAP machine should be done under the care of a doctor or CPAP Consultant.

Can I adjust the pressure myself on my CPAP machine?

The pressure settings on your CPAP machine should always be done under the guidance of your doctor or CPAP Consultant. Pressure settings are determined based on your sleep study results, medical history, Sleep Apnea severity and personal needs.

Automatic CPAP machines (APAP) have more advanced features where the pressure adjusts automatically based on the patient’s breathing patterns. Whilst this is done automatically, without manual adjustment, it is still important to work with your doctor or CPAP Consultant to ensure your CPAP machine settings are optimised.

Making adjustments without proper clinical supervision can result in ineffective CPAP therapy, discomfort with using a CPAP machine and even health risks.

How often should I use my CPAP machine?

You should use your CPAP machine every night to effectively manage your Sleep Apnea and the potential risks associated with Sleep Apnea.  

What are the side effects of using a CPAP machine?

While CPAP is clinically proven to be effective at treating Sleep Apnea, some patients do experience minor side effects, particularly when they are new to using a CPAP machine. Whilst side effects are often temporal, it is best to discuss any side effects with your doctor or CPAP Consultant.

Common side effects of using a CPAP machine include:

  1. Tiredness – sleep quality can be poor when the patient is not yet used to wearing a CPAP mask and having air, particularly at higher pressures delivered to their nose, mouth and throat. Tiredness can also occur if the patient has a poor fitted masks and air escapes, leading to excessive noise and disrupted sleep.

  2. Difficulty falling asleep – when getting used to wearing a CPAP mask and adjusting to CPAP pressure.

  3. Mask discomfort – can occur:
    a. when a patient is new to CPAP treatment;
    b. if the CPAP pressure is high;
    c. if the mask is not fitted correctly;
    d. the mask straps and headgear are fasted around the patient’s head too tight.

  4. Skin irritation – can occur if the mask straps and headgear are fastened too tightly around the patient’s head. This can result in skin irritation, redness or pressure marks. Skin irritation can also occur if the patient is allergic to the CPAP mask materials i.e. silicone cushion

  5. Nasal congestion or dryness – particularly if the CPAP machine is used without a humidifier or if the humidifier setting is too low.

  6. Bloated stomach – tends to occur when patients use a CPAP machine on a higher pressure setting. This can result in bloating, gas and discomfort.

  7. Excessive saliva or dry mouth – can occur if the patient requires a higher CPAP pressure setting or if the patient’s mouth involuntarily opens during the night.

  8. Sore or red eyes – can occur if the mask is not fitted correctly and aid leaks into the patient’s eyes during the night.

  9. Dermatitis or allergic reactions – can occur if the patient is allergic to the mask materials. Use of a hypoallergenic mask cushion and regular cleaning can help manage this.

It is important to discuss any side effects when using a CPAP machine with your doctor and CPAP Consultant. They can provide you with tips and advice to mitigate these issues and to improve comfort and CPAP compliance. With proper guidance, many of these side effects can be managed and the benefits of using a CPAP machine can greatly outweigh the any initial problems.

Are there portable, travel friendly CPAP machines?

Yes. There are portable and lightweight CPAP machines available and convenient for travel. These CPAP machines are typically smaller and lighter than standard CPAP machines, and often have features such as battery pack compatibility, multiple power source compatibility and travel-friendly cases.

The ResMed AirMini is a popular choice for travels. See this product here.  

Are CPAP machines covered under Medicare?

CPAP machines are not covered under Medicare. You can however, check with your private health insurance provider, to see whether you are entitled to any subsidisation under your policy.

Will my private health insurance cover the cost of a CPAP machine?

It really depends on your private health insurance policy. We strongly suggest you discuss with your health fund to discuss whether you are entitled to any CPAP machine coverage.
