Sleep Apnea in Southern Alberta
Sleep apnea is more prevalent than most people realize. In Canada, an estimated one in four adults has some degree of sleep-disordered breathing, with many cases going undiagnosed for years. The condition occurs when the airway collapses during sleep, causing breathing to stop repeatedly throughout the night. Because most people have no memory of these interruptions, the first noticeable signs are often daytime symptoms rather than sleep disturbances.
Common symptoms include persistent daytime fatigue, morning headaches, waking with a dry mouth or sore throat, difficulty concentrating, and mood changes. Loud or irregular snoring and observed breathing pauses during sleep are also strong indicators. More information about the condition is available on the sleep apnea information page. The long-term consequences of leaving sleep apnea untreated are covered at the consequences of untreated sleep apnea page.
Services at the Lethbridge Clinic
- Home sleep apnea testing. A home sleep test lets you complete your sleep study in your own bed. Full instructions are available on the at-home sleep test instructions page.
- CPAP therapy setup and fitting. Once you have a prescription, a respiratory therapist fits you to the right machine and mask before your first night of therapy. This includes selecting the appropriate mask style, sizing the cushion correctly, and configuring your machine settings.
- Mask fitting and troubleshooting. If your current mask is leaking, causing discomfort, or leaving pressure marks, the team can refit you to a different size or style. You do not need a new prescription to switch masks.
- CPAP equipment supply. The Lethbridge clinic stocks a full range of CPAP machines, masks, filters, tubing, and accessories from leading brands.
- Oxygen therapy. For patients requiring supplemental oxygen, home oxygen therapy setup and ongoing supply is available at the Lethbridge location.
- Insurance billing. The clinic works directly with most major Canadian insurers. Visit the insurance coverage page for an overview of what most plans include.
- Virtual care. Virtual care appointments are available for follow-up and ongoing support between clinic visits, which is particularly useful for patients in more remote parts of Southern Alberta.
CPAP Therapy: What to Expect
CPAP therapy delivers a continuous stream of pressurized air through a tube and mask during sleep. This air pressure keeps the airway open and prevents the repeated collapses that cause apnea events. Most patients notice improvements in sleep quality within the first few nights, with daytime fatigue and morning headaches typically reducing within the first two to four weeks. The adjustment period involves getting used to wearing a mask and breathing against air pressure. The respiratory therapists at the Lethbridge clinic configure your machine, set your humidity levels, and provide guidance on building a consistent therapy routine.

Maintaining Your CPAP Equipment in Lethbridge
Regular maintenance keeps your therapy effective and your equipment hygienic. Mask cushions should be replaced every one to three months. Disposable filters need replacing every two to four weeks. Tubing should be washed weekly and replaced every three to six months. The full schedule is covered in the CPAP equipment replacement guide. Most extended health plans cover replacement supplies on a set schedule.
Insurance Coverage for CPAP in Alberta
AHCIP, Alberta’s provincial health plan, does not typically cover CPAP machine costs. Most employer-sponsored extended health benefit plans provide coverage for the machine, mask, and ongoing supplies, though coverage amounts and replacement timelines vary by insurer. Avant Respiratory Lethbridge works directly with most major Canadian insurers and handles billing on your behalf. Visit the insurance coverage page or contact the clinic directly to confirm your benefits before committing to equipment.
