What can I do if I struggle to get used to CPAP for sleep apnoea? 

Adjusting to Continuous Positive Airway Pressure (CPAP) therapy is a common challenge for many people newly diagnosed with sleep apnoea. While the machine is highly effective at maintaining an open airway, the sensation of wearing a mask and breathing against pressurised air can initially feel restrictive or uncomfortable. Fortunately, most difficulties encountered during the early stages of treatment can be resolved through small adjustments to equipment, changes in habit, or support from your clinical team.

• When to contact your sleep clinic for technical adjustments 

Managing Mask Comfort and Fit 

If you are struggling with your CPAP treatment, the first step is to ensure that your mask is the correct size and style for your face shape and breathing habits. Obstructive sleep apnoea (OSA) is a relatively common condition where the walls of the throat relax and narrow during sleep, interrupting normal breathing. A mask that is too tight can cause skin sores, while one that is too loose will leak air, making the treatment less effective and potentially irritating your eyes. 

There are several types of masks available, ranging from small nasal pillows to full face masks. If one style feels claustrophobic or uncomfortable, your sleep clinic can often provide alternatives to try. It is also helpful to practice wearing the mask for short periods during the day while you are awake, such as while reading or watching television, to help your brain get used to the sensation without the added pressure of trying to fall asleep. 

Overcoming Pressure and Breathing Difficulties 

Feeling as though the air pressure is too high or finding it difficult to exhale against the flow of air is a frequent concern for new users. NICE clinical guidelines recommend that CPAP should be offered to people with moderate or severe symptomatic OSAHS, and support should be provided to help with acclimatisation. Many modern CPAP machines have a “ramp” feature, which starts the air at a very low pressure and gradually increases it to your prescribed level after you have fallen asleep. 

If the pressure consistently feels unmanageable, you must speak with your respiratory technician rather than stopping the treatment. They can adjust the settings or potentially switch you to an APAP (automatic) or BiPAP (bilevel) machine if clinically appropriate. These devices can vary the pressure during the night or provide lower pressure when you breathe out, making the experience feel more natural and less like a struggle. 

Addressing Dryness and Skin Irritation 

Physical side effects such as a dry nose, sore throat, or skin rashes are common but manageable issues that often lead people to abandon CPAP therapy. Most CPAP machines come with an integrated humidifier that adds moisture to the air you breathe. Increasing the humidity setting can significantly reduce dryness and prevent the nasal congestion that some people experience as a reaction to the cool air. 

Common Issue	Possible Solution
Dry Mouth or Nose	Increase the humidifier setting or use a heated tube.
Skin Marks/Sores	Adjust the strap tension or try a different mask style.
Nasal Congestion	Use a saline nasal spray or check for mask leaks.
Air Leaks	Ensure the mask is clean and the cushion is not worn out.

For skin irritation, ensure you are cleaning your mask daily with mild, unscented soap to remove oils and bacteria. If the straps are leaving deep marks, you might benefit from soft fabric covers or a different mask harness. It is important to remember that the mask should be just tight enough to create a seal, not so tight that it causes pain. 

Building a Consistent Sleep Habit 

The key to successfully adapting to CPAP is consistency and patience, as it often takes several weeks for the body and brain to fully accept the treatment. Try to use the machine every single time you sleep, including during afternoon naps. If you find you cannot keep the mask on all night, aim to wear it for at least four hours, as even partial use provides some protection for your cardiovascular system. 

If you wake up and find you have taken the mask off in your sleep, simply put it back on and try again. Over time, your body will stop perceiving the mask as a foreign object, and the benefits of improved daytime energy and reduced morning headaches will become your primary motivation. Support from a partner can also be invaluable, as they can encourage you to persist through the initial adjustment phase. 

Conclusion 

Struggling to get used to CPAP is a normal part of the treatment journey, but most issues can be resolved with mask changes, pressure adjustments, or increased humidification. Persistence during the first month is essential for achieving the long term health benefits and restoring your daily energy levels. By working closely with your clinical team and building a consistent habit, you can successfully manage your sleep apnoea. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
