Q: Can I buy a CPAP machine without a prescription?

In the United States, under federal law , CPAP machines are classified as Class II medical devices by the FDA. As such, they require a prescription from a licensed healthcare provider for purchase. This classification is in place because CPAP therapy is considered a medical treatment that needs to be customized for each patient's condition and safety. A prescription ensures that your treatment is appropriate and monitored by a healthcare professional. Most suppliers, including USA Medical Supply, will not ship a CPAP machine without first receiving a valid prescription. You can submit your prescription through the following methods: Text : (413) 200-4191 Email : info@usamedicalsupply.com Fax : (413) 732-2238 This requirement ensures compliance with federal regulations and guarantees you receive the correct equipment and pressure settings.

Q: Differences Between CPAP, APAP, and BiLevel?

CPAP (Continuous Positive Airway Pressure) delivers a fixed pressure throughout the night. APAP (Auto-Adjusting Positive Airway Pressure) automatically adjusts pressure based on your breathing patterns. BiPAP (Bi-Level Positive Airway Pressure) provides two different pressure levels — one for inhalation and a lower one for exhalation. BiPAP is typically recommended for users with specific needs or those who find CPAP uncomfortable.

Blog: Commonly Asked Questions & Answers

1. What Is the ResMed AirSense 11 and How Is It Different From Previous Models?

The ResMed AirSense 11 is a premium CPAP device designed to provide comfortable and user-friendly treatment for sleep apnea. Key differences from previous ResMed models (like the AirSense 10) include:

Enhanced Digital Health Features: Improved Bluetooth and cellular connectivity to sync with ResMed’s myAir™ app.
Sleeker Interface: A modern touchscreen display makes navigation more intuitive.
Advanced Comfort Settings: Upgraded AutoRamp, heated humidifier, and expiratory pressure relief.

Overall, the AirSense 11 incorporates ResMed’s latest design and technology innovations, aiming for a more seamless therapy experience.

2. How Do I Set Up the Device for the First Time?

Unpack and Inspect: Remove the AirSense 11, power cable, tubing, and optional humidifier tub from the box. Check for any damage.
Assemble the Equipment:
- Attach the tubing to the AirSense 11’s air outlet port.
- Connect your preferred CPAP mask to the free end of the tubing.
Fill the Humidifier Tub (Optional): If using the integrated humidifier, fill the tub with distilled water.
Connect to Power: Plug in the device using the supplied power cord and ensure it’s securely connected.
Initial Settings: Follow the on-screen prompts to select language, date, time, and other basic preferences.

Your healthcare provider or DME (Durable Medical Equipment) provider may have pre-programmed your therapy settings, but if not, contact them to confirm the correct pressure settings before using the device.

3. How Do I Clean and Maintain the AirSense 11?

Proper cleaning and maintenance can extend the life of your device and ensure optimum performance.

Daily:
- Wipe down your mask cushion with a mild soap and warm water or use mask wipes specifically designed for CPAP equipment.
- Empty and rinse the humidifier tub with clean water.
Weekly:
- Wash the humidifier tub with a mild detergent in warm water. Rinse thoroughly and allow it to air dry away from direct sunlight.
- Clean the tubing by soaking it in warm soapy water, rinsing it well, and hanging it to dry.
- Wipe the exterior of the device with a soft, slightly damp cloth.
Monthly:
- Check the air filter for dust accumulation. Replace it if it appears dirty or discolored (generally every 1–3 months or as recommended by your provider).

4. What Kind of Mask Can I Use With the AirSense 11?

ResMed offers a variety of mask styles, including:

Nasal Masks: Cover only the nose (e.g., ResMed AirFit™ N30i).
Nasal Pillow Masks: Minimal contact with the face (e.g., ResMed AirFit™ P10).
Full Face Masks: Cover both the nose and mouth (e.g., ResMed AirFit™ F20).

Each mask style is compatible with the standard CPAP tubing and the device’s pressure range. Your choice often depends on comfort preferences, sleeping style, and prescription settings.

5. Is There a Heated Humidifier Included?

Yes, the AirSense 11 features a built-in heated humidifier. Proper humidity levels can:

Reduce dryness in your nasal passages, mouth, and throat.
Improve overall comfort, especially in colder or drier climates.

You can adjust humidity settings on the device’s touchscreen or leave it on “Auto” mode so the AirSense 11 can fine-tune humidity based on your environment.

6. How Do I Track My Therapy Data and Progress?

The myAir™ app by ResMed allows you to:

View compliance hours (i.e., how many hours you’ve used therapy each night).
Track events per hour (AHI—Apnea-Hypopnea Index).
Check mask seal quality and get tips for improvement.

Simply download the myAir™ app (available for iOS and Android), create an account, and follow the prompts to sync your device’s data via Bluetooth or cellular connectivity.

7. How Do I Adjust the Pressure and Other Therapy Settings?

Caution: Changes to therapy pressure should be done under medical supervision.

Patient Menu: Allows you to adjust comfort features such as Ramp Time, Humidity Level, and Tube Temperature (if heated tubing is used).
Clinical Menu: Accessible to clinicians or on prescription from your healthcare provider. This menu manages your therapy mode (CPAP, AutoSet), minimum/maximum pressures, and other clinical parameters.

If you feel your therapy is uncomfortable, consult your sleep specialist rather than self-adjusting pressures.

8. What Is AutoRamp and How Does It Help Me?

AutoRamp is a comfort feature that:

Starts therapy at a lower, more comfortable pressure to help you fall asleep.
Gradually increases the pressure to your prescribed level once it detects you are asleep or after the set Ramp Time.

This feature can make the start of therapy more comfortable for users who are sensitive to high pressures.

9. Can I Travel With the AirSense 11?

Absolutely. Here are some travel tips:

Carry-On: Bring it in your carry-on luggage to avoid damage in checked baggage.
Power Requirements: The device typically works with voltages worldwide (100–240V). Use the correct plug adapter for your destination.
Air Travel: Most airlines allow CPAP machines to be used in-flight, though you should notify them in advance. Check if the seat has a power outlet or consider a battery pack designed for CPAP use.

10. How Quiet Is the AirSense 11?

ResMed devices are known for their quiet operation. The AirSense 11 typically operates in the low 20-decibel range (dBA). Most users report it is quiet enough not to disturb their bed partner’s sleep.

11. Does the AirSense 11 Adjust for Altitude Changes Automatically?

Yes. The AirSense 11 has automatic altitude adjustment, meaning you can use it in various elevations without manual calibration. This is particularly useful for frequent travelers or those living in higher altitudes.

12. What If I Experience Dryness or Nasal Congestion?

Increase Humidity: Try raising your humidifier setting or switch to a heated tube if dryness persists.
Nasal Saline Spray: A saline rinse before and after use can help maintain nasal moisture.
Mask Fit: An improperly fitting mask can worsen congestion. Ensure your mask fit is correct and not leaking excessively.

If symptoms persist, consult a sleep therapist or your healthcare provider for further adjustments.

13. How Often Do I Replace the Filters, Mask Cushions, and Other Accessories?

The following are general guidelines:

Disposable Filters: Replace every 1–3 months or when visibly dirty.
Mask Cushion: Replace every 1–2 months (or as soon as it loses seal).
Tubing: Replace every 3–6 months if signs of wear appear.
Humidifier Tub: Replace every 6–12 months, depending on usage and mineral buildup.

Always refer to your device’s user manual and insurance guidelines for specific replacement schedules.

14. How Do I Connect to the myAir™ App?

Download: Get the myAir™ app from the App Store (iOS) or Google Play (Android).
Create Account: Use an email and password.
Sync Device: Follow the on-screen instructions to pair via Bluetooth. Some models connect via built-in cellular connectivity automatically, so you might only need to confirm your details.

15. Are Software or Firmware Updates Available for AirSense 11?

ResMed occasionally releases software or firmware updates to improve device performance. These updates typically happen automatically via the device’s wireless connectivity. If prompted, follow the on-screen instructions to update. If in doubt, contact your healthcare provider or ResMed customer support for assistance.

16. What Are Common Error Messages and How Do I Troubleshoot Them?

“AirTube disconnected”: Ensure the tubing is firmly attached at both ends.
“High leak detected”: Check mask fit, cushion wear, and if necessary, replace or adjust your mask.
“Water tub not inserted”: Push the water tub in fully until it clicks into place.
No Display / Power Issues: Check that your power cord is firmly plugged in and your outlet is functioning.

If an error persists, consult the user manual or contact ResMed technical support.

17. Can I Adjust the AirSense 11 Brightness and Display Settings?

Yes, the touchscreen allows you to adjust screen brightness. You can also set it to dim after a certain period of inactivity. Check the “Settings” or “Preferences” menu on the device for these options.

18. Who Should I Contact for Additional Support?

Healthcare Provider / Sleep Specialist: For questions on therapy settings, pressure adjustments, or ongoing symptoms.
DME Supplier: For replacement parts, device care, or warranty queries.
ResMed Customer Support: For technical issues, software updates, or connectivity concerns.

Can I buy a CPAP machine without a prescription?

In the United States, under federal law, CPAP machines are classified as Class II medical devices by the FDA. As such, they require a prescription from a licensed healthcare provider for purchase. This classification is in place because CPAP therapy is considered a medical treatment that needs to be customized for each patient's condition and safety.

A prescription ensures that your treatment is appropriate and monitored by a healthcare professional. Most suppliers, including USA Medical Supply, will not ship a CPAP machine without first receiving a valid prescription. You can submit your prescription through the following methods:

Text: (413) 200-4191
Email: info@usamedicalsupply.com
Fax: (413) 732-2238

This requirement ensures compliance with federal regulations and guarantees you receive the correct equipment and pressure settings.

Do you accept insurance?

No, and we are not contracted with any provider. We do provide a Universal Claim Form that you can download [here] if you wish to try and get reimbursed yourself.

Insurance billing using a Universal Claim Form (UCF) involves submitting a standardized document to your insurance provider to request reimbursement for medical expenses. However, it is not guaranteed that you will be reimbursed, and we are not implying that you will be. It is important to check with your insurance provider to understand your coverage and eligibility for reimbursement, especially for durable medical equipment (DME) like CPAP machines and supplies.

Here’s how the process typically works:

1. Obtain a Universal Claim Form

The UCF is usually provided by your insurance company or available on their website. The form includes sections to detail the medical services or products you've received, such as CPAP supplies, and what you're seeking reimbursement for.

2. Complete the Form

Personal Information: Enter your personal details, including your name, insurance policy number, and contact information.
Provider Information: Include details of the healthcare provider or supplier (such as USA Medical Supply), like their name, address, and tax identification number (TIN).
Service Details: Provide specific information about the medical service or product. For CPAP equipment, this might include the model number, date of purchase, and a description of the equipment (e.g., CPAP machine, mask, tubing).
Cost and Charges: Indicate the total cost, including what you've already paid out-of-pocket.

3. Attach Supporting Documentation

Receipts: Attach copies of receipts for the medical service or product you've purchased.
Prescription: If required, include a copy of the prescription from your healthcare provider for the CPAP equipment.
Explanation of Benefits (EOB): If your insurance company has already processed part of the claim, include any EOB documents that detail what they have paid and what remains your responsibility.

4. Submit the Claim Form

Send the completed form and all supporting documentation to the address provided by your insurance company. Some insurers may allow you to submit the form electronically, while others may require it to be mailed.

5. Review and Processing

Once submitted, your insurance company will review the claim and determine the amount of reimbursement based on your policy’s coverage for durable medical equipment (DME), such as CPAP machines and supplies. The insurer may contact you or the supplier if more information is needed.

6. Receive Reimbursement

After approval, the insurance company will send you a reimbursement check or direct deposit for the amount they cover, minus any deductibles or co-payments.

Things to Note:

Coverage Varies: Insurance policies differ in their coverage for DME, so check with your provider to understand your benefits.
Out-of-Network Providers: If your supplier is out-of-network, you might receive partial or no reimbursement.
Time Limit: Ensure you submit the claim within the time frame allowed by your insurance provider, as delays can result in denial.

Please remember, reimbursement is not guaranteed. You need to verify all details with your insurance provider.

Additionally, we do accept HSA/FSA payments, which you may be able to use to cover the cost of CPAP equipment and supplies.

Replacement Schedule for CPAP Supplies?

To maintain effective therapy, it’s essential to replace certain CPAP components regularly:

Mask Cushions: Every 1-3 months
Tubing: Every 6-12 months
Filters: Every 1-3 months
Headgear: Every 6 months These recommendations ensure your equipment stays in optimal condition and your therapy remains effective.

How to Clean and Maintain CPAP Equipment?

Cleaning your CPAP equipment regularly is crucial for effective therapy and hygiene:

CPAP Mask and Tubing: Wash weekly with warm water and mild detergent. Let it air dry completely before use.
Humidifier Chamber: Clean once a week with mild soap and warm water, and replace it every 6 months.
CPAP Machine Exterior: Wipe down weekly with a dry, non-abrasive cloth. Avoid using ozone-based cleaning devices as they may damage your machine and void warranties.

Differences Between CPAP, APAP, and BiLevel?

CPAP (Continuous Positive Airway Pressure) delivers a fixed pressure throughout the night.
APAP (Auto-Adjusting Positive Airway Pressure) automatically adjusts pressure based on your breathing patterns.
BiPAP (Bi-Level Positive Airway Pressure) provides two different pressure levels — one for inhalation and a lower one for exhalation. BiPAP is typically recommended for users with specific needs or those who find CPAP uncomfortable.

How to Choose a CPAP Mask?

Choosing the right mask is key for comfort and therapy compliance:

Full Face Mask: Best for mouth breathers or those with nasal congestion.
Nasal Mask: Ideal for those who breathe through their nose and move around during sleep.
Nasal Pillow Mask: Great for users who prefer minimal contact with their face. If unsure, our customer support can guide you through finding the best option based on your preferences.

Traveling with a CPAP Machine?

CPAP machines are FAA-approved and can be carried as a medical device during air travel. We do Sell Travel Models.Our Travel Models are compact enough to use during flights. Consider investing in a portable battery for convenience if you frequently travel.

How Do Heated and Non-Heated Tubing Differ?

Heated Tubing: Helps prevent condensation buildup by maintaining consistent temperature from the humidifier to your airway. Also they have an anti-microbial effect by preventing condensation from building in the tubing.
Non-Heated Tubing: More affordable, lighter, and suitable if you don’t experience condensation issues. It’s compatible with most CPAP machines and masks.

What are the Signs of Sleep Apnea?

Common signs of sleep apnea include:

Loud snoring
Gasping or choking during sleep
Daytime fatigue
Morning headaches If you experience these symptoms, consult a healthcare provider for a sleep study to diagnose sleep apnea.
