Continuous Positive Airway Pressure (CPAP) therapy is a widespread prescription for a disorder called obstructive sleep apnea (OSA). Sleep apnea occurs when a person's airway collapses during sleep and breathing stops. CPAP therapy uses a machine that delivers a constant flow of air pressure to help keep the airway open.
There are several CPAP mask options available for use. Here, we shall focus on the two popular selections—nasal and full-face masks. Before we delve into a comparison of the two, let us first understand the basic components of each.
Nasal CPAP Masks
Nasal CPAP masks cover your nose and are designed to provide airflow only through the nasal passage, with definite benefits over the full-face varieties.
Advantages:
- Comfort: With their small size and lightweight design, nasal masks offer unique functions that increase comfort while reducing complaints. They’ll be easier to keep on throughout the night.
- Reduced Claustrophobia: Another area where nasal masks seem to have the upper hand is related to feelings of claustrophobia, making them a better choice for anyone who feels constricted with a full face mask.
- Secure Fit: Getting a good seal can be difficult for side sleepers, but since nasal masks are engineered to keep you in place when you adjust positions while sleeping, (mainly nasal pillows) seal leakage tends to be less of a problem.
- Speech & Drink: Without necessarily taking off the mask, you can speak, drink and even read with a nasal mask while going through your bedtime routine.
- Skin Irritation: Smaller covering area means less skin irritation and can result in a less likelihood of pressure sores associated with larger masks which cripple your comfort levels.
Disadvantages:
- If You Breathe Through Your Mouth: Nasal masks are unsuitable for patients who breathe through their mouth during sleep as breathing through your mouth can lead to dry mouth and a less effective CPAP therapy.
- Nasal Blockage: It may be difficult for those who have a history of nasal congestion, or who have allergies, to get the most from nasal masks. A congested nose can obstruct airflow, leading to restless sleep.
- Pressure: At higher pressure settings nasal masks can result in less comfort and efficacy compared to oral masks.
Full Face CPAP Masks
Full-face CPAP masks provide airflow through both the nose and the mouth as they cover the nose and mouth simultaneously.
Advantages:
- Comfort: All full face masks accommodate every kind of sleeping condition.
- No Nasal Dependence: These are better for individuals with severe nasal congestion, allergies, or other nasal issues that make it hard to breathe with congested nasal passages.
- Tolerance: Full-face masks have a large gap for the bridge of the nose therefore even at a higher pressure the user feels comfortable.
- Secure Fit: Full-face masks work well if their fit is secure due to a loose fit from experiencing too many head movements during sleep resulting in leakages or inconsistent seals throughout the night.
Disadvantages:
- Bulky: Full-face masks are more bulky, especially about advancement, but advanced cushions are comparatively less reactive to pressure. This can be disadvantageous for side sleepers who may feel the weight of the mask pressing on their pillow.
- Claustrophobia: The added coverage might make some users feel enclosed, which could be challenging if they have claustrophobia and are also more prone to removing it during the night.
- Skin Irritation: As the full face masks have greater contact area, there are greater chances of skin irritations, pressure sores, and marks can be seen mostly in side sleepers who experience more mask movement.
- Barrier Mouth Issue: With a total face mask on, it might be difficult to talk or drink anything till removing the mask, which can sometimes prevent smooth bedtime routines.
Considerations for Side Sleepers
For side sleepers (and some back sleepers), some factors will come into play when deciding between a full-face CPAP mask and a nasal mask. These are mask stability, leak, and comfort when lying sideways.
- Mask Stability: People who sleep on the side need a mask that stays stable in various positions. It may be easier for side sleepers who experience mask movement to use nasal masks, especially nasal pillows, as they offer a minimal but secure contact point that allows for better stability.
- Seal Leak Control: Having a good seal is critical in effective CPAP therapy. Nasal masks are targeted for side sleepers, so there is less leakage compared with full-face masks, where issues with shifting do occur.
- Comfort: Full-face masks are generally bulkier due to cushion pads. Therefore, you may feel offset while using it. For side sleepers, the mask could bother your pillow. Nasal masks are more comfortable in that case.
- Breathing Needs: Mouth breathers or people who have a smaller nasal size can be more comfortable in a full face mask (A step further from nasal pillows).
Choosing the Right Mask
The best mask for you depends on some personal factors, including your breathing habits, what makes you comfortable, and your need for sleep position. Some tips that could help you select a mask:
- Try Different Masks to Find the Right One: The best mask is a matter of personal preference. Most CPAP suppliers have trial periods or allow exchanges, which is helpful when looking for the mask that works for you.
- Consult a Sleep Specialist: Consult a sleep specialist to decide which mask type is right for you. They can provide insights based on your medical records and CPAP needs.
- Adjustable Straps: Masks with adjustable straps can be tailored to fit firmly without affecting your sleep position, which is important for side sleeping in particular.
- Cushion Choice: Additional Considerations for Side Sleepers—A personal favorite pillow is so important. If you cannot seem to find one that cushions both the head and the mask, consider looking into a specific CPAP-designed pillow.
In conclusion, nasal masks and full-face masks both have their advantages and downsides, pace the traditional. Although nasal masks are comfortable and stable, they do not work well for mouth-breathers. Full-face masks are less preferable to some people as they might be bulkier, hot, and uncomfortable. The most suitable mask would depend on your personal comfort zone, your specific requirements, etc., and is something that you should decide based on the combination of comfort, seal integrity, and mouth and nose breathing.
