Starting CPAP Therapy: What to Expect in Your First Few Weeks

Starting CPAP therapy can feel unfamiliar at first. You're getting used to a mask, airflow, tubing and a new bedtime routine—all at the same time.

For some people, CPAP feels comfortable almost immediately. For others, finding the right mask fit and becoming accustomed to the sensation of positive airway pressure takes a little longer.

Knowing what to expect can make those first few weeks easier.

What Does CPAP Therapy Do?

CPAP stands for Continuous Positive Airway Pressure.

A CPAP machine delivers pressurised air through a mask while you sleep. The positive airway pressure helps keep the upper airway open and reduces the breathing interruptions associated with obstructive sleep apnoea.

Some machines provide a fixed pressure, while automatic CPAP or APAP machines can adjust pressure within a prescribed or configured range according to your needs during the night.

Getting Used to Your CPAP Mask

The mask is one of the most important parts of your CPAP setup.

There are three main mask styles:

• Full face masks, which cover the nose and mouth

• Nasal masks, which deliver therapy through the nose

• Nasal pillow masks, which use small cushions that seal at the nostrils

No single mask is right for everyone.

Your breathing habits, face shape, sleeping position and preference for more or less facial contact can all influence which mask feels most comfortable.

If you're struggling with CPAP, don't automatically assume the machine or therapy isn't right for you. Sometimes changing the mask, cushion size or fitting can make a significant difference.

Your CPAP Mask Shouldn't Need to Be Extremely Tight

A common reaction to mask leaks is to tighten the headgear.

More tension isn't always better.

A CPAP mask should be secure enough to maintain a reliable seal without creating unnecessary pressure on your face.

If you're experiencing leaks, check that the cushion is positioned correctly, that you're using the appropriate size and that the headgear is adjusted evenly.

It's also worth checking whether your CPAP hose is pulling against the mask when you move during sleep.

Getting Used to the Air Pressure

The sensation of pressurised air can feel unusual when you first use CPAP.

If it feels difficult at first, you may find it helpful to wear the mask for short periods while you're awake. For example, you could put the mask on while reading or watching television.

This gives you a chance to get familiar with the mask and airflow without trying to fall asleep.

Many CPAP machines also have comfort features designed to make starting therapy easier. Available features depend on your machine and settings.

What If I Feel Air Leaking From My Mask?

Some airflow from a CPAP mask is normal. Masks have intentional venting that allows exhaled air to escape.

A significant leak around the mask cushion, however, may affect comfort and therapy.

If you're experiencing unwanted leaks:

• Reposition the mask before tightening it

• Check the cushion size and fit

• Adjust the headgear evenly

• Check that the cushion is clean

• Look for worn mask components

• Check whether your pillow or bedding is pushing against the mask

• Make sure the hose isn't pulling on the mask

If leaks continue, a different mask size or design may be worth considering.

What About Dryness?

Some people experience dryness in the nose, mouth or throat when starting CPAP.

Many modern CPAP machines can be used with heated humidification, which adds moisture to the therapy air.

Your mask type, room conditions, humidifier settings and whether air is escaping through your mouth can all influence how dry CPAP feels.

If dryness continues to be a problem, it's worth reviewing your mask fit and CPAP setup rather than simply accepting the discomfort.

Should I Use CPAP Every Night?

If CPAP has been recommended for you, consistency is important.

Using CPAP whenever you sleep also gives you more opportunity to become accustomed to the equipment and establish it as part of your normal bedtime routine.

If you're finding regular use difficult, try to identify the specific problem.

Is it the mask?

Leaks?

Dryness?

Pressure sensation?

Hose position?

Noise?

Difficulty falling asleep?

Identifying the problem makes it much easier to find a practical solution.

How Do I Know Whether My CPAP Is Working?

Many modern CPAP machines record therapy information.

Depending on the machine, this may include usage, mask leak, therapy pressure, and breathing events detected during the night.

These numbers can be useful, but you should consider them alongside how you're sleeping, how consistently you're using CPAP, and your overall therapy setup.

If you're unsure how to interpret your CPAP information, ask for help rather than changing therapy settings based solely on a single night's numbers.

Don't Ignore an Uncomfortable Mask

A CPAP mask is something you'll potentially wear for many hours every night.

Persistent discomfort, excessive leaking or a mask that repeatedly wakes you deserves attention.

Sometimes the solution is as simple as adjusting the headgear or changing the cushion size. In other cases, a different mask style may suit you better.

AwakeNZ offers full face, nasal and nasal pillow CPAP masks from ResMed and Fisher & Paykel, along with support to help you understand the available options.

What If I'm Not Sure Which CPAP Machine Is Right for Me?

CPAP machines differ in features, humidification, connectivity, size and how therapy pressure is delivered.

AwakeNZ supplies CPAP and APAP machines from ResMed and Fisher & Paykel, including popular home and travel options.

If you'd prefer to try CPAP before buying a machine, a CPAP trial or rental can help you get familiar with therapy and compare equipment options.

Give Yourself Time to Adjust

Starting CPAP is a new experience, and adjustment isn't identical for everyone.

Rather than expecting everything to feel perfect on the first night, focus on identifying and solving specific problems as they arise.

A comfortable mask, appropriate setup and consistent use can make the transition to CPAP much easier.
