This identifies the machine as continuous, auto adjusting, or bilevel operation. This does not identify whether the machine automatically adjusts pressure. Auto adjusting refers to APAP, whereas BiPAP Auto is differentiated using the Auto Pressure Adjustment property. BiPAP machines are defined further using Spontaneous or Timed properties.
A CPAP machine blows one constant pressure of air into your passageway throughout the night. Your ideal pressure was determined during your sleep study.
A BiPAP machine delivers two separate pressures of air; One when the patient inhales and a separate pressure when they exhale. The machine alternates between the two set pressures to help optimize your sleep apnea treatment.
An APAP machine automatically adjusts on a breath by breath basis to blow the minimum pressure needed to keep your airway open during sleep. This allows your machine to provide you with your ideal pressure nightly.
Warranty is the length of time that the manufacturer will guarantee a product to be free of defects. Warranties vary in length depending on manufacturer, but generally all machines come with a 2 Year Warranty.
|5 Years||2 Years||2 Years|
This is the level of sound the machine produces at a pressure of 10cm, standing 1 meter away or roughly 3 feet from machine. Measured in Decibels, the values also indicate whether the machine is considered a "quiet CPAP"; see Quiet property.
|26 dB||<30 dBA||24 dBA|
This identifies which machines have a decibel rating of 29 and lower. This does not account for use with the humidifier attached, which could supply additional volume that can muffle or amplify sound. This property does not account for noise that travels through the CPAP tubing, seemingly sounding louder than the measured db rating.
This indicates which manuals are included with the purchase of a CPAP machine. Most all machines come with a patient manual; also called 'user manual', which may or may not have pressure setting instructions. Some machines come with both the patient and quick setup guide or both patient and clinician manuals.
|Patient/Quick Setup||Patient||Patient/Quick Setup|
Looking to travel? We have found some machines are easier to travel with than others. These smaller and more lightweight machines are still robust enough for constant daily use as well as travel.
|Under 3 lbs|
This measures only the weight of the machine and does not include total weight of power cables, bag, additional batteries or non-built-in humidifiers.
This is the actual weight of the CPAP Machine without any accessories, power cord, or humidifier. Machines with a weight 3lbs or less are also identified in the Under 3 lbs property.
|2.75 lbs||2.8 lbs||1.8 lbs|
This is the combined weight of the machine, heated humidifier, power cables, bag and hose.
|6.1 lbs||6.8 lbs||7.4 lbs|
This is the combined dimensions of the CPAP with the Heated humidifier.
|6.5" x 8.4" x 6.4"||6.5" x 10.75" x 4"||11.25"x6.25"x3.25"|

|Machine Size Only|
Measures the overall dimension of the machine only. Machines with a built-in humidifier are marked NA and must refer to Entire Size dimensions.
|4.2" x 6.5" x 6.9"||7" x 5.5" x 4"||6" x 5.5" x 3.25"|
This indicates which heated humidifier works best with the listed CPAP machine. In some instances, Built-in is used to describe a machine/humidifier combination system. The Fisher and Paykel HC150 was used for machines that do not have an integrated or built in humidifier system.
|IntelliPAP Heated||System One 60 Series||H5i|
Identifies which CPAP has a humidifier that is built into the CPAP. Built-In humidifiers cannot be separated from the CPAP machine.
|Heated Humidifier Type|
This property identifies how the machine incorporates a Heated Humidifier. Build In humidifiers are built into the CPAP machine and cannot be separated from the machine. Integrated humidifiers connect directly to the CPAP machine and they can only be used with compatible CPAP machines. With Integrated¯ humidifiers, the CPAP machine, can be separated and used without the humidifier. CPAP machines that do not have a built in humidifier and do not have an integrated humidifier option have to use a Stand Alone humidifier as the machine's heated humidifier option. Stand Alone¯ humidifiers can be used with any machine and connect to the CPAP machine with an additional hose.
Manufacturers are finding ways to reduce the amount of water that collects in the CPAP hose when using a Heated Humidifier. The Rainout Reduction feature varies by manufacturer and machine and can be anything from an integrated heated hose, to technology that measures the humidity at the mask and adjusts the humidity to reduce rainout.
|No||60 Series Heated Tube||Climate Control|
|Integrated Heated Hose|
This indicates that the machine has an integrated heated hose option to enhance humidification and reduce rainout. An integrated heated hose draws its power from the machine itself and does not have a separate power cord and is adjusted through the machine settings.
|Auto Pressure Adjustment|
This property defines whether the machine automatically adjusts pressure to meet the needs of the CPAP user on a breath-by-breath basis. All APAP machines are defined as 'Auto Adjusting', but some BiPAP's also use an Auto feature on both the IPAP and EPAP. If not marked, Yes, assume the machine does not have AUTO capabilities.
A CPAP (Constant Positive Air Pressure) delivers continuous airflow at a prescribed pressure at 4cm to 30cm. APAP operates between a range and BiPAP machines are a mix of ranges and constant pressures. This pressure is measured in centimeters of water pressure (H2O) and 4-20cm is average pressure range on most CPAP machines.
|4-20cm H20||4-20cm H2O||4-20cm H20|
|EPAP Pressure Range|
This Property lists the operating range for the Exhalation Positive Airway Pressure (EPAP). This is the pressure setting used when you exhale. EPAP is always lower than the IPAP (inhalation) pressure, making breathing out easier and more comfortable.
Pressure Relief is a feature that lowers your therapy pressure to help with difficulties breathing against the machine's airflow, providing a more comfortable and natural breathing pattern. Assistance can occur on the Exhalation, on the Inhalation, and on both exhalation and inhalation at the same time.
|SmartFlex||A-Flex||AutoSet with Easy-Breathe|
The Ramp feature allows the user to start treatment at a lower pressure to fall asleep with, gradually raising the pressure over a set time. This is a comfort setting and can set from 0 to 45 minutes on most CPAP machines.
This property defines whether the machine is capable of continuously blowing a constant pressure. All CPAP machines are defined as 'continuous', but some BiPAP's and APAP's also come with a CPAP mode; some BiPAP and BiLevel machines Do NOT. By setting the IPAP and EPAP to the same pressure, a CPAP Mode is achieved, preventing the EPAP pressure from dropping.
|Direct Battery Operation|
Indicates which machines have a DC port in which you can use to connect a battery pack or a deep cycle marine battery with an optional DC cable. This is different from an integrated battery that works only with the machine it was designed for. (i.e. Everest CPAP Machine) see property Integrated Battery
Domestic Voltage is the voltage that is used with a standard wall outlet in the United States and ranges from 100-120 volts. International Voltage can range from 220v-240v AC.
|100-240V AC||100-240V AC||100-240V AC|
|Optional DC Cable|
A 'Yes' answer indicates that the CPAP Machine has an optional DC cable that plugs directly into a DC port (see _Direct Battery Operation_). This allows you to use a DC power source, such as a battery or car cigarette lighter. Although some cables already come with battery terminal leads, some DC cables will need a separate part that connects the cigarette lighter adapter to another adapter with terminal leads.
An integrated battery pack attaches to and functions seamlessly with the machine it is integrated with. It allows your CPAP to run on AC and fail over to the DC battery only if necessary.
Identifies which machines are data capable and have the ability to track your therapy progress over time. The machine captures key metrics like AHI (Apnea/Hypopnea Index), Leakage, and most pressure used. Depending on the machine, the data can be retrieved through an on Machine Screen Display (MSD), through Optional Software (OS), and/or through SmartCode (SC).
|MSD; OS||MSD||MSD; OS|
This property marks the machines that have the ability to record performance data on a removable card. Some machines that are flagged as having software (seeOptional Software), do not have removable memory cards, rather instead, records information on-board and must use a download cable to retrieve the data from the machine.
Software is an option on some CPAP machines. The software can give details on compliance and performance. The patient or physician downloads the data from the CPAP machine to determine how long a patient has used their machine each night and how well the machine is working to stop Apnea/Hypopnea events. This property shows the software package to use for machine that has the ability to transfer data to your computer and report Hours of Usage. See Advanced Software for a list of machines that can report AHI or Leakage.
|Auto Altitude Adjustment|
Altitude Adjustment is defined as the machine's ability to compensate for changes in altitude. Compensation can either occur manually or automatically. Manual adjustments occur within the Setup Menu and must be set by the user. Automatic requires no user intervention.
This feature turns the machines off and on when putting on or taking off the mask. When you put your mask on the machines senses you breathing and turns itself on. Take off the mask and the machine turns off.
|Mask Off Alert|
This feature detects excessive mask leaks due to poor cushion seal or when a user stops therapy by removing a mask when in use. The alert can be in the form of an audible alarm (ALARM) or a text message on the unit's LCD display (LCD).
Spontaneous (S) mode tells the machine to start blowing at IPAP pressure with no specific interval set. The machine must wait and detect a break in the breathing cycle before reacting, switching from exhalation to inhalation. If a backup rate is needed, then the unit will need a time interval setting and will be marked 'Yes' on the Timed property.
Timed (T) or Spontaneous Timed (ST) modes provide a customizable backup rate that forces the machine to switch from exhalation to inhalation. In ST Mode, the machine monitors the breathing cycle and switches from EPAP to IPAP once the backup time is met or whenever the break is detected through the sensors; whichever occurs first. The time aspect is only meant to act as a backup respiratory rate to the (S) function (see Spontaneous). This is used for patients with central sleep apnea, or those who need non-invasive mechanical ventilation.

5 Year Manufacturer IntelliPAP Machine Warranty
DeVilbiss offers an industry leading 5 (five) year manufacturer warranty on IntelliPAP machine orders placed on or after 2/15/2012.
3 Year Manufacturer IntelliPAP Humidifier Warranty
DeVilbiss offers a 3 (three) year manufacturer warranty on IntelliPAP Humidifier orders placed on or after 2/15/2012.
CPAP.com will work with the manufacturer on your behalf if the machine needs repairs. Please follow these steps:
Please note: The manufacturer warranty is voided by water damage or misuse of the machine.
DeVilbiss offers free firmware upgrades for the IntelliPAP Series of CPAP machines. For example, The AutoAdjust update allows existing owners to add SmartCode and SmartFlex technologies. You can check for the most recent firmware update here: Model DV5 Series Firmware Updates.
Once you have downloaded the firmware software, use the IntelliPAP CPAP to PC Firmware Upgrade Serial Cable to upload your DeVilbiss firmware to the machine from your computer. The cable connects to the back of the CPAP and to any PC serial port on your computer.
IntelliPAP users must have a PC serial port available for the firmware upgrade to work. The DeVilbiss software only supports a serial connection; USB-to-USB or other connections will not work. If your computer does not come with a serial port, CPAP.com provides a USB male to Serial male (9-pin) DB-9 RS-232 adapter that allows users to update their IntelliPAP CPAP machines through your computer's USB port. If you do not have a serial port available, then you will need to buy both cords together: IntelliPAP Firmware Upgrade Cable with USB-to-Serial PC Adapter.
Here are some basic instructions on how to install a firmware update once you have downloaded the software to your PC:
A bacteria filter will not install directly to the air outlet port on the IntelliPAP Heated Humidifier. The filter is too bulky and there is not enough space. IntelliPAP humidifier owners can order the FlexiTube Angle Adapter for CPAP and BiPAP Machines to provide a spacer between the humidifier and the bacteria filter. Your CPAP hose can then fit onto the other end of the bacteria filter.
*Note: This is a battery life estimation based on the battery and the machine. Each machine has unique power needs. Look for the Battery kit that has all the cables needed to safely run your machine. Each battery kit page contains a note about which machines are compatible with that specific battery kit. Please always read the "Important Tips" tab for further information on battery use.
"I switched from a two-year old CPAP to this auto CPAP four nights ago. I am amazed at how much the tech has advanced in two years. This unit is much smaller and lighter, which is very helpful for travel. It also is much quieter.
It took a few nights for me to adjust to the auto adjusting pressure level. Although I was used to constant pressure, I am beginning to appreciate the benefits of auto adjusting. The average pressure seems much lower -- at least for me -- and it requires less effort to breathe.
An interesting feature -- you can turn the machine on, or you can put on a mask and take a breath, and it turns on automatically.
Although the literature says the unit will have a battery operation option, DeVilbiss has not released that yet."
"I paid extra to get this machine because it would adjust the pressure automatically. However, when I began to use it, my wife reported that I snored a lot during the night WITH THE MACHINE ON and it kept at the minimum pressure. I had to raise the minimum pressure until it was at my prescribed pressure before I would stop snoring at night. So the part of it detecting and increasing the pressure as needed does not work at least on this particular machine. It almost makes me think it is defective. The one aspect that is nice is that it does go on and off automatically when I put it on or take it off. I also made the mistake of not ordering the option to upload the data from the machine to my computer. If I had done that, perhaps that would give me some insight as to why it is not increasing the pressure to stop my snoring. Unfortunately now it costs me more money to get the data upload option because it is not part of a package. Unless you order that, the display really does not give any useful information.
Other than that, the machine is compact and easy to install and do teh setup. The documentation is clear. But if I had known about its lack of respponse to my snoring, I would have bought a simple CPAP and not an "Auto" model."
"Bought this as an upgrade from a 7 yr old ResMed S8 that had gone south. What a difference! Easy sleeping, super quiet, easy to set up."
"good , handy , easy to use"
"The S9 is a quieter unit, but much more fragile than the IntelliPAP. This Auto-CPAP is nicely adjustable - almost customizable. Auto adjust is the way to go for anyone who has to use this type of equipment.....much more comfortable than fixed pressure units. I would highly recommend this unit - it woudl be great if it were just a little quieter. I get my sound information from my wife who doesn't sleep as soundly as I do; she is very sensitive to the noise my units have made.
This IntelliPAP is fairly tall with the humidifier installed and it is subject to tipping over when the hose is pulled on at night. The hose port on the humidifier points upwards - giving the hose even more leverage. For this reason, I keep my IntellliPAP on the floor where it has no place to fall if I pull on the hose while I am asleep. The low baciklight feature is great and allow me to find the off switch at night when I have to get up and go to the bathroom - it is not too bright, either. This is my third CPAP over the past 8 years and I would recommend it to anyone. [The S9 is a great unit, but the knob on top breaks off too easily and water gets into the hose easily if the unit is distrurbed at night. ]"
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.
We provide our customers with many tools to make informed decisions about their machine purchases. Options include:
We work very hard to provide many different ways for our customers to compare products. Here are the machine product guides we have created and maintain:
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 / BiPAP / APAP 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.
All CPAP masks work with all machines.
Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine and/or humidifier.
We provide many easy ways to get your prescription:
The only care a CPAP 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.
There are some other suggested actions to care for your machine:
Exhalation relief is a comfort feature offered by two manufactures which reduces the air flow at the time of exhalation making the breathing process more natural.
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. The image below shows the black foam filter at the back of the Everest 3 CPAP Machine.
An adapter may be required to plug a US power cord into a wall outlet in a foreign country. CPAP.com sells an assortment pack of World Traveler Power Adapter Plugs, which allow CPAP machines to plug into different types of wall sockets found in different countries.
All the models CPAP.com sell contain power converters that enable the machine to operate on any AC current from 100 to 240 volts without any adjustment. Check with your dealer or manufacturer to see if your machine needs an external converter that lowers the voltage from 240 to 120 VAC.
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 they ease up to their pressure.
CPAP machines which record full data (like AHI and leak info):
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 big local hospital or ask you physician for sleep lab phone numbers. 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.
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.
First you need to determine if your machine is configured to operate on DC power and has a DC power outlet. If your machine does have a DC power outlet and you want to run your marine battery, then you will need the correct DC cable for your machine and an adapter cable that fits over the cigarette lighter plug and ends in alligator clips.
CPAP.com sells complete battery kits with everything you need for your machine including the right cables for your machine and the battery. You can find the right battery kit for your machine here.
If your machine does not have a DC power outlet, then you will also need an inverter to be able to run your machine on battery power.
If you have questions about the specific power needs of your machine, review the "Power" tab on your machine's product page, or give us a call at 1-800-356-5221.
Some CPAP users find it more pleasant to breath with APAP than with CPAP because the pressure automatically changes as needed to deliver the minimal pressure needed. With a CPAP, on the other hand, the pressure is set at the highest necessary to keep the airway open, even though the high pressure is needed only a fraction of the time.
There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend II Travel CPAP Machine has Batterie Options available for that can set up as a fail-over, back up battery. Review the "Power" Tab on the machine page.
CPAP.com sells battery packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
All CPAPs will operate on DC power with the use of an inverter to change the current from DC to AC before it reaches the machine. However, many will operate on DC power without the need for an inverter, just a power cord that plugs into the CPAP and ends in a cigarette lighter plug.
Inverters do require a lot of power. If you need to use an inverter to run your machine on battery power, the inverter will probably take about half the life off the battery.
To determine if your CPAP will operate without an inverter, look for a DC outlet on the machine, either at the back or on the side, with a single opening directly in the center. It should be labeled "DC Power" or similar term. You can also review our Compare Charts to see if your machine has a optional DC cable option.
For longer battery use, we suggest a deep-cycle marine battery. A CPAP set at 10cm will usually run for about three nights before having to recharge a deep cycle marine battery. A car battery will usually run a machine for 8 hours and still start the car.
There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. CPAP.com sells full battery kits that come with everything needed to run your machine off battery power including the right cables needed for your machine and a battery. You can find the battery kit for your machine here. On each battery kit page, you can input your machine and pressure setting to see an estimate battery life for your machine.
Your CPAP does NOT count against your carry on limits. Allow for an additional 10-20 minutes in security, not likely but it happens. If airport personnel ask about the CPAP, let them know politely that it is a medical device (a CPAP unit). Most of them understand what it is and that it is an exception to the normal rules. We provide a luggage tag for CPAP systems: http://www.cpap.com/productpage/medical-identification-luggage-tag-cpap-equipment.html
You can use your CPAP on board, just use batteries or make sure you're seated by a power outlet. You can call or reserve one of these seats online with most airlines. Alternatively visit Seat Guru , a website that works with most major airlines.
Be sure to bring spare parts and a back up mask. If you're in a bind, CPAP.com delivers all over the US and to most international destinations.
To prepare for your international travel, be sure to:
The IntelliPAP AutoAdjust generates advanced user data. The IntelliPAP Standard only generates basic compliance information. See the image below for a complete breakdown of the reports available for each type of IntelliPAP. See a Sample Report.
This is a list of report topics generated when using SmartCode to track therapy effectiveness.
Usage Threshold: Determines the minimum amount of time that the patient must use the device to be logged as a compliant day. Device settings allow for 4 or 5 hours, with 4 hours being the default setting. This setting can be changed in the device clinical set-up menu.
Adherence Score: Shows the maximum adherence achieved for any period of thirty consecutive days of use within a ninety-day time frame. The score represents the percentage of days, within thirty consecutive days, where usage met or exceeded the 'Usage Threshold.' The Adherence Score reports the 'best' consecutive thirty days of usage. For example, if the 'best' 30 out of the last 90 days show 22 days used above the usage threshold and 8 days below the threshold, then the Adherence Score would show 73% (22/30). For this calculation, the usage must be continuous hours and longer than the Usage Threshold.
Days at Least X Hours: Shows the number of days in the timeframe where the total usage within each day is at least X hours. "X" represents the 'Usage Threshold' setting in the patient's device. For this calculation, all usage within a 24-hour period is recorded.
% Days at Least X Hours: Shows the percentage of days in the timeframe where the total usage within each day is at least X hours. "X" represents the 'Usage Threshold' setting in the patient's device. For this calculation, all usage within a 24-hour period is recorded.
Day Count: Shows a count of days for each timeframe. If, for example, the 90-day code is collected at day 45 of therapy, then the "Day Count" for this code will be 45 days. In most cases, however, the day count is equal to the days in the code's timeframe(s).
While Breathing Hours: While breathing hours are only available within the last-day timeframe and with the cumulative code. This measurement shows the total hours of use.
95th Percentile Pressure: AutoAdjust pressure was at or below this pressure 95-percent of the time it is in use.
90th Percentile Pressure: AutoAdjust pressure was at or below this pressure 90-percent of the time it is in use.
AHI: Apnea/Hypopnea Index (AHI) represents the average number of apneas and hypopneas per hour for the timeframe.
Pressure Plateau Time: Represents the percentage of time the AutoAdjust spent at the upper pressure setting. A value of 10% or more indicates a possible need to raise the upper pressure setting to allow higher pressures.
High Leak Flow Time: Shows the percentage of time where leak was above 95 liters per minute. A value of 10% or more indicates that the mask fit should be checked.
NRI: Non-Responding Event Index (NRI) represents the average number of non-responding events per hour. A non-responding event is a respiratory event that is detected but by design does not result in a pressure change during AutoAdjust therapy.
EPI: The Exhale Puff Index (EPI) is the number of exhale puff events detected per hour. Exhale puffing is caused by inhaling through the patient circuit and exhaling through the mouth.
There are three (3) tabs that attach the SmartLink Module to the DeVilbiss IntelliPAP CPAP Machine. Image of SmartLink Module's adjoining face. Also, there is a release button located on the same side as the oximeter and data cord connections.
The top 2 'tabs' and connector must be aligned first, then the last tab can be slid into place. If all 3 are aligned at once, the module will not attach properly. Typically, there will be an audible 'clicking' noise when the module is fully attached. Verify that all points are connected by lightly pulling on the module after installation.
If you are receiving an "EA1 Module Fault Contact Provider" message on your IntelliPAP screen, your SmartLink module is not properly attached.
