Discover the Life-Changing Power of CPAP: Transform Your Sleep, Transform Your Life
How CPAP Works
A CPAP device delivers a continuous stream of pressurized air through tubing and a mask to keep the upper airway open during sleep. The steady pressure prevents the throat and airway muscles from collapsing and stops the pauses in breathing that define obstructive sleep apnea (OSA). Many machines include humidifiers and replaceable filters to increase comfort.
Common Indications and Referral Criteria
We typically see referrals for people who snore loudly, wake gasping, or report daytime sleepiness. A sleep specialist or your primary care provider may recommend testing if you have high blood pressure, heart disease, obesity, or observed apneas. In practice, anyone diagnosed with moderate to severe OSA or who has clinically significant daytime impairment is a candidate for CPAP therapy. We coordinate with local physicians and discharge planners to make sure the device and supplies meet your medical needs.
Getting Diagnosed, Prescribed, and Covered in South Texas
Local Testing Options: Sleep Labs and Home Sleep Tests
In the Rio Grande Valley you can access in-lab sleep studies and modern home sleep apnea tests. In-lab polysomnography gives a full picture of sleep stages and breathing events. Home tests are convenient and often sufficient for diagnosing OSA in straightforward cases. We work with local sleep labs and providers to help you understand results and next steps. For more insights on sleep health topics, visit our blog where we share helpful information.
Insurance, Medicare/Medicaid, and DME Requirements
Coverage usually requires documentation: a formal diagnosis, a face-to-face evaluation, and a written order for a CPAP device. Medicare and many insurers expect proof of medical necessity and may have trial or compliance rules. As a trusted DME provider, we help you navigate paperwork, set up device delivery, and meet DME requirements so you get the supplies and replacements you need.

Choosing and Buying the Right CPAP in Harlingen and South Texas
CPAP vs APAP vs BiPAP: Which Is Right For You?
CPAP provides a single preset pressure. APAP (auto-adjusting) varies pressure night to night as your needs change. BiPAP offers two pressures, higher for inhale, lower for exhale, and is used for more complex respiratory disorders. We’ll help match device type to your diagnosis, comfort preferences, and any coexisting conditions.
Mask Types, Fit Tips, and Sizing
Masks come in nasal, nasal pillow, and full-face styles. A proper fit reduces leaks and improves adherence. Bring your facial measurements or try masks in person: our team and licensed respiratory therapist can size and fit your mask for maximum comfort. Small adjustments, different cushions, headgear, or a nasal pillow, can make a big difference.
Humidification, Filters, and Climate Considerations
South Texas humidity and dust affect comfort and equipment. Heated humidifiers reduce dryness and nasal congestion. Use machine filters to cut down on dust and pollen. If you travel to drier or more humid places, adjustable humidification and seasonal maintenance keep your therapy reliable. We stock CPAP machines and supplies and can show you options, visit our local store to see what’s in stock.
Your Journey to Better Sleep: Making CPAP Work for You
Cleaning, Mold Prevention, and Routine Maintenance
Daily quick-cleaning of the mask and nightly airing of components lowers bacteria and mold risk. Weekly warm-soapy washes for tubing, cushions, and humidifier chambers are a good baseline. Replace disposable filters and mask cushions on the schedule advised by the manufacturer.
Common Problems and Practical Fixes
Leaks are the most frequent issue, often solved by refitting the mask or switching cushion type. Dryness or congestion responds to humidifier adjustments. Pressure discomfort can improve with a ramp feature or a switch to APAP/BiPAP if clinically appropriate. Noise is usually filter- or humidifier-related and can be fixed with simple maintenance.
Tips To Improve Comfort and Long-Term Adherence
Start gradually. Use the ramp setting, practice wearing the mask while awake, and take advantage of heated humidification. Keep sleep diaries and bring concerns to us or your respiratory therapist. We’ll troubleshoot face-to-face or by phone and can provide replacement parts quickly, call today to find the right equipment for you.

Frequently Asked Questions About CPAP Devices in South Texas
Does Medicare cover CPAP supplies in Texas?
Yes, Medicare Part B covers CPAP therapy including the machine, mask, tubing, and filters when you meet specific criteria: a sleep study confirming sleep apnea, a face-to-face evaluation with your doctor, and a written prescription. Medicare typically covers 80% of approved costs after your deductible. We handle Medicare billing and can explain your coverage details.
How often should I replace my CPAP mask and supplies?
Medicare and most insurers follow this replacement schedule: masks every 3 months, cushions and pillows monthly, tubing every 3 months, headgear every 6 months, filters monthly (or more frequently in dusty South Texas conditions), and water chambers every 6 months. We track your replacement schedule and remind you when supplies are due.
Can I travel with my CPAP machine on airlines from Valley International Airport?
Yes, CPAP machines are considered medical devices and don’t count toward carry-on limits. Bring your prescription, pack your CPAP in a clear bag for TSA screening, and consider a travel-sized machine if you fly frequently. For international travel from McAllen or Brownsville airports, check voltage requirements. We stock travel cases and portable batteries for your convenience.
What’s the difference between a CPAP and oxygen concentrator?
CPAP machines deliver pressurized air to keep airways open during sleep but don’t add oxygen. Oxygen concentrators extract and deliver concentrated oxygen for people with low blood oxygen levels. Some patients need both devices. Our respiratory therapist can explain which equipment your condition requires.
How long does it take to get used to a CPAP machine?
Most people adapt within 2-4 weeks with consistent use. Start by wearing your mask while awake, use the ramp feature to gradually increase pressure, and ensure proper mask fit. Our respiratory therapist provides personalized tips, and we offer follow-up support during your adjustment period.
Can the South Texas humidity affect my CPAP machine?
Yes, our Rio Grande Valley climate creates unique considerations. High humidity can increase condensation in tubing (rainout), while dust requires more frequent filter changes. We recommend heated tubing for condensation control and keeping extra filters on hand, especially during windy seasons.
What should I do if my CPAP stops working during a power outage?
Keep a backup battery system, especially during hurricane season. Portable CPAP batteries provide 1-3 nights of power depending on your pressure settings. We stock battery backup solutions and can help you prepare an emergency kit with essential supplies before storm season.
Can MacPherson’s Medical Supply help if I already have a CPAP prescription?
Yes. Bring your prescription and insurance information to our Harlingen location. We’ll verify coverage, help select the right equipment, provide mask fitting, and offer ongoing support. Our respiratory therapist ensures you’re comfortable with your device before leaving our store.
