A good night's sleep is vital for your health, but for people living with sleep apnea, restful sleep can be difficult to achieve. One of the most common and effective treatments is CPAP therapy—short for Continuous Positive Airway Pressure. But what exactly is a CPAP machine, how does it work, and what should you know before starting therapy?
Let’s walk through the basics and address some of the most common questions we hear from patients at Okotoks HC Pharmacy.
What Is a CPAP Machine?
A CPAP machine delivers a constant, steady flow of air through a mask that keeps your airway open during sleep. This prevents breathing interruptions caused by obstructive sleep apnea (OSA)—a condition where throat muscles relax excessively and block airflow, causing loud snoring, gasping, or repeated awakenings.
Who Needs a CPAP Machine?
CPAP therapy is prescribed for individuals diagnosed with moderate to severe obstructive sleep apnea following a sleep study. These studies are conducted by sleep specialists or respiratory therapists, often through an at-home sleep test or overnight lab monitoring. Based on the results, a specialist will determine whether you require CPAP and prescribe the appropriate air pressure settings and oxygen flow, if needed.
Your Top CPAP Questions—Answered
💤 How Long Does It Take to Feel Better?
Every patient is different. Some people notice improved sleep quality and reduced daytime fatigue within a few nights, while others take several weeks to adjust. Consistency is key—use your machine every night, even during naps, for the best results.
😴 What If I Still Snore While Using CPAP?
Occasional snoring can still happen, especially if your mask isn't sealing properly or if your air pressure setting needs adjustment. If snoring persists, talk to your sleep clinician—your pressure settings may need to be fine-tuned.
😣 How Can I Avoid Pressure Sores on My Face?
Pressure marks and skin irritation are often caused by overtightened or poorly fitting masks. To prevent this:
-
Ensure your mask is properly fitted—not too tight, not too loose.
-
Consider using mask liners or nasal cushions.
-
Alternate between different mask styles if one area is getting sore.
-
Keep your skin clean and dry before putting on the mask.
If sores persist, speak to your supplier or respiratory therapist for alternative mask options.
✈️ Should I Travel with My CPAP?
Absolutely. Your CPAP is essential for your health—even when you travel. Most CPAP machines are portable and TSA-approved for air travel. Carry it in your hand luggage and use a travel case for protection. We recommend packing an extra filter and checking for power compatibility if you’re going abroad.
Tip: Ask your sleep clinic or pharmacy about travel-sized CPAP machines or battery backup options for camping or remote trips.
🗓️ How Often Should I Replace My Mask, Hose, and Filter?
Like any medical device, your CPAP components need regular replacement:
-
CPAP tubing (hose): Every 3 months
-
Disposable filters: Every 2–4 weeks
-
Reusable filters: Wash weekly and replace every 6 months
-
Full mask system: Every 6-12 months (or sooner if showing wear)
We carry a wide range of replacement parts and accessories in-store to keep your therapy effective and comfortable.
🧼 What’s the Daily Cleaning and Maintenance Protocol?
Proper cleaning prevents buildup of bacteria, mold, and allergens:
Daily:
-
Wipe down your mask cushion with a gentle cloth or mask wipe
-
Empty and rinse the water chamber (if your unit has a humidifier)
Weekly:
-
Wash the mask, tubing, and water chamber in warm, soapy water (use mild dish soap)
-
Let all parts air dry completely before reassembling
-
Rinse or replace filters as needed
Avoid using harsh cleaners, vinegar, or alcohol, which can damage components.
