CPAP Video & FAQ

Frequently Asked Questions (FAQs)

What does CPAP therapy do?

CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. It is traditionally provided through a nasal mask that seals around the nose to maintain the pressure level.

Which CPAP masks work on which machines?

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:

ResMed AirFit™ N20 Nasal Mask
ResMed AirFit™ F20 Full Face
ResMed AirTouch™ F20 Full Face
ResMed AirFit™ P10 Nasal Pillow

When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

What comes with my machine?

Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP, APAP, and BiPAP machines do not come with a delivery system or mask. CPAP masks must be purchased separately.

To see the list of what specifically comes with each machine, you can Browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.

Do all CPAPs use filters?

Yes, all CPAPs use at least one filter that is usually a type of foam material and washable. Some CPAPs offer finer filtration with the addition of a disposable paper filter.

Cleaning and changing filters is the only maintenance required for a CPAP machine.

The filters are located at the back of the machine at the air intake.

Are prescriptions required for mask, machine, humidifier, and EPAP purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or EPAP therapy, including Provent and Bongo RX. You will also need a prescription to purchase the Nightbalance POSA device.

What is ramp?

The ramp button on a machine is a feature that allows for a gradual pressure build-up to your prescribed pressure. The feature is enjoyed by those with high pressures because it eases up to their pressure.

What is exhalation relief?

Exhalation relief is a comfort feature which reduces the air flow at the time of exhalation, making the breathing process more natural.

The following are the different types of exhalation relief names by manufacturer.

Philips Respironics = C-Flex, C-Flex+, A-Flex and Bi-Flex
Resmed = EPR (Expiratory Pressure Relief)
3B Medical = RESlex
Apex Medical = PVA (Pressure Variation Algorithm) Pressure Relief
Curative Medical = EUT (Expiratory Unloading Technology)
DeVilbiss = SmartFlex
Fisher & Paykel = SensAwake Technology
Human Design Medical = Z-Breathe
Somnetics = EZEX

Here are some machines with an exhalation relief feature:

Transcend Auto miniCPAP™ Machine with EZEX
PR System One REMStar 60 Series Auto with Bluetooth
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
+ See More

What is Bi-Flex?

Bi-Flex is a feature that makes breathing back against CPAP pressure easier to do. Bi-Flex pressure relief technology offers pressure relief at the transition from exhalation to inhalation, at the transition from inhalation to exhalation, and during exhalation to make BiPAP therapy more like natural breathing.

Here are some machines with Bi-Flex:

DreamStation BiPAP Auto Machine
PR System One REMStar 60 Series BiPAP Auto with Bluetooth

What is the difference between Bi-Flex and C-flex?

C-Flex only works at the start of an exhale. Bi-Flex works during the transition from exhalation to inhalation, the transition from inhalation to exhalation and during exhalation.

What maintenance is required on machines?

The only care a CPAP, APAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.

Here are some other suggested actions to care for your machine:

Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.

What data capable machines are available?

CPAP machines which record full data (such as AHI and leak info):

AutoPAP ("Autotitrating CPAP" or "APAP") machines which record full data:

BiLevel ("BiPAP") machines which record full data:

CPAP Machines that only record compliance data (hours used) are:

How do I use a battery to operate my CPAP?

All machines can connect to DC power. Some machines are configured to operate on DC Power and have a DC power outlet. Other machines require AC power and will need an Inverter that turns DC power to AC power.

Having the proper equipment is the biggest key to successfully operating the machine from a battery. For example, if your machine does have a DC outlet and you want to run your machine from a marine battery, be sure to get the correct DC cable for the machine, as well as an adapter cable with alligator clips that fits over the cigarette lighter plug.

CPAP.com sells complete battery kits with everything you need for many machines including the correct cables for those machines and batteries. You can see if there is a battery kit available for your machine Here. If you have questions about the specific power needs of your machine, review the 'Power' tab found on the machine's product page, or give us a call at 1-800-356-5221.

What is CPAP therapy?

CPAP stands for Continuous Positive Airway Pressure. CPAP therapy is the most commonly recommended, and the most effective, treatment for obstructive sleep apnea.

A CPAP machine provides air at a constant prescribed pressure. The air is delivered to the person through a tube and a CPAP mask. CPAP therapy provides a constant airflow which keeps the airway open so uninterrupted breathing is maintained during sleep. The air stream eliminates Sleep Apnea events and allows the person to get a restful sleep.

The level of air pressure required to maintain your airway is determined during your sleep study. Your doctor will write a prescription for a CPAP machine set at that pressure.

CPAP therapy is delivered through a nasal mask that seals around the nose, nasal pillows which seal at the nasal opening, or nasal prong masks that seal inside the nares. Full face masks are available for a person who breathes through both the nose and mouth. Many innovative and comfortable options are available and advances in the delivery of CPAP therapy are continually occurring.

For instance: Some machines offer a comfort feature such as FLEX or EPR technology. It provides exhalation relief, a slight drop in pressure at the time of exhalation to help make therapy more natural. APAP, BiPAP and BiLevel machines offer various levels of pressure throughout the night.

What are the benefits of using CPAP therapy?

Successful CPAP users report improvements in:

Quality of Sleep
Quality of Life
Energy and Motivation
Mood & Disposition
Job Performance
Sexual Drive and Performance
Alertness While Driving

A failure to use CPAP therapy to treat Sleep Apnea may increase your risk for conditions linked to untreated OSA:

Hypertension (OSA increases your risk of hypertension by up to five times)
Stroke
Congestive Heart Failure (CHF)

How do I change the pressure setting of my machine?

When a physician orders a pressure change, or a patient moves to an area with a very different altitude and does not have an altitude compensating machine, there are a number of ways to ensure you are receiving CPAP therapy at the correct pressure.

Sleep laboratories and sleep disorder centers may be willing to make this pressure change. Just call a local hospital or ask your physician to recommend a sleep lab. Be sure to take your prescription.

A second way is to do it yourself. We sell manometers that are very portable, accurate, and simple to use. All the machines we sell come with instructions on how to set pressure to physician orders. Most patients have little trouble doing this themselves. If you need help we can talk you through the procedure. Contact us by phone at 1-800-356-5221.

Gauge Manometer (for pressure measurements)

Fisher and Paykel Water Column CPAP Manometer with HC325 Chamber

A third option is to ship the machine to us with the new prescription. We will set it and ship it back.

It is the law and good common sense to run all sleep disorder devices at the prescribed pressure. If you think your prescribed pressure is wrong, talk to your physician.

Why might I prefer an APAP machine?

Some CPAP users find it more pleasant to breathe with an APAP than with CPAP. The pressure delivered by an APAP machine automatically changes as needed to deliver the minimal pressure required to maintain the airway. The pressure delivered by a CPAP machine is set to a single pressure, the highest necessary to keep the airway open as determined during the sleep study. This is the case even when the higher pressure is needed only a fraction of the time.

What does an APAP prescription need to say?

An APAP prescription must contain all of the following information:

One of the following words or phrases: "APAP", "AutoPAP", "AutoSet", "Auto CPAP", "Auto Adjusting CPAP", "Self Adjusting CPAP", "CPAP" or "Continuous Positive Airway Pressure" or similar term.
Your physician's contact information
Your physician's signature
The patient's full name

An APAP prescription may contain the following information:

Your pressure range (Optional, Not Required)
- Example: 4-20 CM/H20
- Example: 4-20
- Example: 6-18 CM/H2O
- Example: 6-18

CPAP prescriptions are accepted for Auto Adjusting (APAP) machines.
