3. What does CPAP stand for?

CPAP is the acronym for Continuous Positive Airway Pressure. CPAP therapy provides a constant flow of air at a set pressure into the airway to ensure that the airway stays open through the night.

4. Why are your prices so low?

We buy all new equipment from the distributors in large quantities. Because of this, we get a discount and we can pass the savings on to you. All of our products are new from the distributor.

Most of our CPAP machines are warranted for two years by manufacturer-issued warranties. We are happy to handle any problems that arise and will gladly contact the manufacturer for you. Turn around time for a repair can be as long as 2-3 weeks. Thirty-day rental machines are available to help you while the manufacturer of your machine is attempting repair or replacement.

6. Which CPAP mask will work with my machine?

All CPAP masks and CPAP tubing are made to a standard size. Because of this, you can choose any mask to use with your CPAP or BiLevel machine. You should choose your CPAP mask based on previous good experiences with a mask, a doctor’s recommendation based upon your sleep study, or suggestions from CPAP providers who have experience in this field, such as ourselves. Give us a call for questions or suggestions!

7. Which type of mask should I choose?

This is a tough question because it truly varies on an individual basis. There are traditional nasal masks (by far, the most popular with CPAP users), alternative nasal masksfull face masks (for those patients who have problems with mouth breathing or leaking from the mouth), nasal interface systems (such as nasal pillows systems), and oral masks (such as the Fisher & Paykel Oracle Oral). Each of these masks has benefits and drawbacks and may work for some and not for others. For the best possible choice, stick with what has worked in the past. If you do well with nasal CPAP masks, stick with them. If this is your first mask purchase or you are unhappy with your current mask type, please give us a call and we will be happy to give you suggestions based on your individual therapy needs.

8. What is the purpose of adding humidification to my machine?

Heated or Passover humidification can definitely increase your comfort while completing your therapy. Humidification adds moisture to the air being blown into your airway, and without it, many patients find that they have significant drying out of their nostrils, mouths, and throats. Studies have shown that because patients’ comfort levels are increased when humidification is added to therapy, their compliance with the therapy is also greatly increased as well. If you are purchasing your first CPAP or do not normally use humidification, we strongly recommend adding a humidifier to your machine.

9. Is there a machine that has a CPAP and humidifier all in one unit?

Many of our CPAP machines have the option to add on integrated humidifiers that attach in some way to the machine. But these units are still essentially two separate pieces of equipment. There are only a few manufacturers who actually produce an all-in-one humidified CPAP machine. These units require only one outlet with a removable chamber to add water to the humidifier component.

10. What are auto-titrating or auto CPAP machines?

Auto-titrating CPAPs are machines that automatically adjust your pressure throughout the night to ensure that at all times you are receiving the exact pressure necessary to keep your airway open. Because of this, you do not need to have another sleep study done every time your prescription pressure does not seem to be working for you. The auto machine senses and adjusts to whatever pressure is necessary for your needs. Even the smallest change, such as a loss or gain of only ten pounds, can change the optimal pressure for your therapy. A standard CPAP will not adjust to these changing needs. It would have to be reset. Auto CPAPs sense your new needs and function according to what your body demands. If you are unsure whether or not an auto CPAP is correct for your therapy, please give us a call and we will be happy to help you choose the best machine for your needs!

11. How Do I Clean my tubing and mask?

For home cleaning, mix two parts vinegar and one part warm water. Allow tubing and mask parts to soak for a few minutes. Rinse clean and allow to air dry.

12. What is a BIPAP machine?

BIPAP (Bilevel Positive Airway Pressure) machines deliver airflow to the airway at a certain pressure in the same manner as a CPAP, but they have different pressures for the patient’s inhalation and exhalation. Inhalation pressures are higher and keep the patient’s airway open, but exhalation pressures are lower to make breathing out against the airflow easier for patients. BIPAPs are only needed in specialized cases where the pressure must be very high, patients cannot tolerate a standard CPAP, or a muscular disease is present that makes it harder for a patient to breathe against the pressure. If you believe you may need a BIPAP, please consult with your physician.

13. What is the difference between compliance and clinical data?

Compliance data monitors patients usage. Clinical data monitors the patients breathing rate, snoring index, apnea and hypopnea index, average pressure used, and breathing trends.

14. What are the benefits of having a CPAP machine with compliance and clinical data

Compliance data allows the physician or employer to monitor usage. The clinical data assists the physician in making necessary changes to your treatment.

15. Can any manufacturer’s CPAP mask be used with any CPAP or BiPAP machine?

All masks are universal and can be used with any CPAP or BiPAP machine from any manufacture, excluding the Transcend & Resmed Airmini

16. Why is a full face mask recommended for mouth breathers?

If a patient is a mouth breather and uses a nasal mask, the pressure is reduced making treatment ineffective. Full face masks allow the patient to breathe from the nose or the mouth, while still obtaining maximum treatment.

17. How often should I change my CPAP supplies?

Many CPAP and BiPAP users don’t realize that most of the supplies associated with sleep therapy are designed to be disposable. Masks, tubing, filters, and headgear are not designed to last extreme amounts of time, and using them past their recommended life span can actually jeopardize your CPAP therapy. Delicate silicone mask cushions can develop leaks, clogged filters can allow dust and pollen to be delivered into your airway, and over-stretched headgear can require extreme tightening, causing pressure point pain.

18. What is the benefit of using the custom CPAP bed pillows?

A traditional bed pillow can affect the seal of your CPAP mask during movement while your sleep. The custom CPAP bed pillows are designed to help prevent the mask from moving while you sleep.

19. What do I do if my nose becomes sore from using a nasal pillow system?

First, you want to make sure you are using the correct size nasal pillows. Nasal pillows should have a secure fit. Using nasal pillows that are too large can flare the nostrils causing irritation. Using nasal pillows that are too small can create friction in the nostrils, also causing irritation. Not using heated humidification can dry your nasal passages, causing discomfort. 
Recommended solutions would be using heated humidification, or using a nasal moist gel.

20. What if my pressure seems too high?

Most first time CPAP users experience this sensation. It normally takes 1 to 2 weeks for you to adjust to the pressure. If you still feel your pressure is to high, you must contact your physician before any adjustments can be made. Patience is extremely important while you adjust to your pressure.

21.What happens if I wake up and my CPAP mask has been pulled off?

This is a common problem with new CPAP users. Once your body adjusts to having a CPAP mask on your face while you sleep, this will become less of a problem. If you still experience problems after 2 to 4 weeks of consistent use, please contact our CPAP experts for help.

22. What happens if my machine is out of warranty and needs repairs?

25. How often should I change the water in my humidifier?

Distilled water should always be used to prevent calcium build up in your water chamber and also to prevent sinus infections. Your water should be changed on a daily basis. Always rinse your humidifier chamber out before adding new water. Washing your humidifier on a weekly basis helps prevent bacterial build-up.

26. What is the difference between CPAP and BiPAP therapy?

CPAP therapy is used for patients who have been diagnosed with OSA (obstructive sleep apnea) and only require one continuous pressure. BiPAP therapy is normally used for patients who have more complex forms of sleep disorders. BiPAP therapy allows for both inhalation and exhalation pressures to be set at different ranges. Your physician will always determine which therapy type you need.

27. What happens if I become very bloated while using CPAP therapy?

Patients who experience an abnormal amount of gas build-up commonly referred to as gastric distention, normally are swallowing air causing excess air in the stomach. If you experience this condition, please contact your physician.

28. What if I continue to experience mask leakage during the night?

Mask leakage can be caused by a variety of issues. With your machine running, pull your CPAP mask away from your face so that the seal can be properly inflated. Then gently set the CPAP mask back into place. Another common problem is having your CPAP mask too tight. Try loosening the head straps to allow proper inflation of the seal. A misconception with many CPAP users is that a CPAP mask should be leak-free 100% of the time. All CPAP masks will leak from time to time. Eventually, you will need to readjust your mask if a leak occurs. Purchasing a different type of CPAP mask may not always solve your leakage problem. Always allow yourself ample time to adjust to the CPAP mask. If you continue to have problems, give our CPAP experts a call for alternative solutions.
