Nasal Congestion and CPAP: Breaking the Cycle

You can't use CPAP if you can't breathe through your nose. But sometimes CPAP itself seems to make congestion worse.

It doesn't have to be this way.

The Congestion Cycle

The problem:

1. Dry air from CPAP irritates nasal passages
2. Irritation causes swelling and mucus production
3. Congestion makes breathing through nose harder
4. You breathe through mouth or remove mask
5. Therapy suffers

Breaking it: Address the root cause, not just the symptom.

Types of Nasal Congestion

Dry-Air Related

Signs:

• Worse after using CPAP
• Dryness feeling
• Crusting in nose

Cause: Insufficient humidification

Inflammatory/Allergic

Signs:

• Present before CPAP too
• Seasonal patterns
• Other allergy symptoms

Cause: Allergies, sensitivities

Structural

Signs:

• Always one side worse
• Long-standing issue
• Previous nasal injury

Cause: Deviated septum or other structural issue

Solutions

For Dry-Air Congestion

Increase humidity:

• Turn up humidifier setting
• Use heated tubing
• Fill chamber fully each night

Nasal care:

• Saline spray before bed
• Nasal gel (water-based)
• Saline rinse (neti pot or squeeze bottle)

For Allergic Congestion

Reduce allergens:

• Clean bedding weekly (hot water)
• Use allergen-proof pillow covers
• Keep bedroom dust-free
• HEPA filter in bedroom

Medications:

• Nasal steroid spray (Flonase, Nasacort): works best if used daily
• Antihistamines (Zyrtec, Claritin): oral or nasal
• Talk to your doctor about what's right for you

For Structural Issues

Evaluation: See an ENT if congestion is severe and one-sided or doesn't respond to other treatments.

Options may include:

• Nasal dilators (Breathe Right strips, internal dilators)
• Medical treatment
• Surgical correction for severe cases

Night-to-Night Management

Before Bed Routine

1. Take allergy medication if using
2. Saline rinse or spray
3. Wait 15-20 minutes
4. Apply any nasal treatments
5. Put on CPAP

During the Night

If you wake congested:

• Saline spray at bedside
• Blow nose gently
• Return to CPAP

If severely congested:

• It's okay to take a night off occasionally
• Don't make it a habit
• Address underlying cause

Morning

If congested in morning:

• Steam (hot shower)
• Saline rinse
• Note pattern for provider

When to Use Full Face Mask

If nasal congestion is chronic and you use a nasal or pillows mask:

Consider full face mask:

• Allows mouth breathing when needed
• Keeps CPAP working even when stuffed up
• Can be used during colds too

Discuss with provider: They can help you find the right option

When to See a Doctor

Get medical help if:

• Congestion is severe and persistent
• You can't use CPAP because of it
• You have sinus pain or pressure
• Congestion is only on one side
• You have other symptoms (fever, facial pain)

Tracking your congestion patterns helps your provider help you. Note it in the Drift portal. [Log in →](/patient/login)
