Why Does My CPAP Make Me Cough?

 Why Does My CPAP Make Me Cough?

Continuous Positive Airway Pressure (CPAP) therapy is a highly effective treatment for obstructive sleep apnea and other sleep-related breathing disorders. However, some individuals may experience side effects or discomfort during CPAP therapy, one of which can be coughing. If you find that your CPAP machine is making you cough, it's essential to understand the potential causes and explore ways to alleviate this issue.

Common Causes of Coughing with CPAP

1. Dry Airway:

   • Many CPAP machines use pressurized air, which can sometimes dry out the airway and respiratory passages. When the air you breathe in is dry, it may irritate your throat and cause coughing.

2. Irritation from the CPAP Mask:

   • The CPAP mask can sometimes cause irritation to the nose, throat, or airway. This can be due to the mask's material, improper fit, or pressure applied by the mask on the face.

3. Allergies:

   • Allergies to dust, pollen, or other allergens can exacerbate coughing during CPAP therapy. The airflow from the CPAP machine can carry allergens into the airway, triggering coughing and other allergic reactions.

4. Nasal Congestion:

   • If you have nasal congestion or a stuffy nose, the pressure from the CPAP machine may force air into your nasal passages, causing discomfort and coughing.

5. Excessive Pressure:

   • CPAP machines are set to deliver a specific pressure level prescribed by your healthcare provider. If the pressure is too high or not adjusted correctly, it may lead to coughing, especially if the air feels forceful or overwhelming.

6. Breathing Against the Pressure:

   • Some individuals may unconsciously resist or fight against the airflow pressure delivered by the CPAP machine. This can create discomfort and potentially lead to coughing.

Tips to Alleviate Coughing with CPAP

1. Use a Humidifier: Consider using a CPAP machine with a built-in humidifier or an external humidifier attachment. Humidified air can help prevent dryness and irritation in the airway.

2. Adjust Humidity Levels: If your CPAP machine has a humidification feature, adjust the humidity level to find the setting that offers the most comfort and minimizes coughing.

3. Check Your Mask: Ensure that your CPAP mask fits properly and comfortably. If it's too tight or causing discomfort, try a different mask type or size.

4. Keep Your Mask Clean: Regularly clean and maintain your CPAP mask, cushion, and headgear to prevent irritation from dirt or residue buildup.

5. Allergy Management: If allergies are a concern, keep your sleeping environment clean and free from allergens. Consider using allergen-proof pillow covers and mattress encasements.

6. Nasal Decongestion: Address nasal congestion with saline nasal sprays or consult your healthcare provider for appropriate treatments.

7. Pressure Adjustment: If you find that the pressure from your CPAP machine is causing discomfort, discuss pressure adjustments with your healthcare provider. They can fine-tune the settings to improve your comfort.

8. Practice Relaxation Techniques: Try relaxation techniques before and during CPAP therapy to reduce anxiety and help you adjust to the airflow more easily.

Conclusion

Coughing during CPAP therapy can be uncomfortable and disrupt your sleep. However, with the right adjustments and proper management, you can alleviate this issue and experience the full benefits of CPAP treatment. Consult with your healthcare provider, CPAP supplier, or sleep specialist to address the specific cause of your coughing and find solutions that work best for you. Remember that effective CPAP therapy should provide relief from sleep apnea symptoms without causing persistent discomfort or side effects like coughing.
