Sandman Duo BiLevel CPAP Machine

The Sandman Duo is lightweight, compact and user-friendly. The Duo BiLevel features an intelligent pressure stability and respiratory events detection system that reacts to an obstruction event. Also, the Sandman Series includes the humidifier technology called HumidControl. The built in humidifier actually measures the temperature outside the chamber and adjusts the heater plate to minimize condensation. At 2.64 pounds, take the Sandman Duo anywhere and feel confident you will receive effective therapy.

Learn More About Your New Machine

The Sandman Duo BiLevel machine is designed to provide accurate therapy pressure using an advanced Adaptive Pressure Stability system that helps in detecting respiratory events. The Duo is equipped with pressure and flow sensors that detect apneas, hypopneas, inspiratory flow limitations and snoring. Once an event occurs, the machine reacts using an enhanced algorithm that smoothly adjusts the pressure during events.

The Sandman Series uses Covidien's unique Adaptive Pressure Stability (APS) technology that limits the peak to peak variations of CPAP pressure when a user breathes. Adaptive Pressure Stability responds quickly and accurately to several common conditions that result in changes from your prescribed pressure down to each breath.

Common conditions affecting Pressure

Switching Masks
Mask leaks
Altitude
Natural respiratory effort
Barometric pressure
Sleep stage
Body position

Each patient is different and Covidien has created FlowSens technology that allows you to adjust the machine's sensitivity along with setting the rise time. Allowing you to adjust the Sandman Duo to match your apnea needs.

True Circuit Calibration helps the Sandman Duo compensate for pressure variances created when using different styles of masks and tubing. For instance, when using a Full Face Mask, a digital signal processor microcontroller helps to improve flow generation capabilities, delivering an accurate pressure at the mask.

The Sandman Duo records compliance data which allows a digital signal processor to work interactively with the user and provides accurate flow control. For advanced therapy effectiveness, use the Sandman Therapy Software to help visualize user sessions and take control of your sleep therapy.

The device is quiet, discreet and user-friendly. Small and light, traveling with the Sandman is convenient. Use either AC or DC power from an external battery source. If altitude is an issue, the Auto Altitude Compensation feature accounts for barometric changes. All Sandman CPAP units contain an advanced pressure transducer that compensates for altitudes up to 9,000 feet, which could effect your cpap as much as 3cmH2o of pressure.

Covidien also addresses the need for humidity, incorporating a built-in heated humidifier, together weighing only 2.75 pounds. The humidifier is located to the rear of the CPAP with a water chamber that is easy to clean. Using a new technology, HumidControl, the humidifier provides the best temperature according to the relative humidity outside the water chamber. This prevents water from collecting in the CPAP hose and keeps the humidification level constant throughout the night.

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.

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.

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.

We provide many easy ways to get your prescription:

We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.
Fax your prescription to our toll-free fax number: 866.353.2727, or our international fax number: 713.541.7377
Email your prescription to cpap@cpap.com
Upload your prescription in your account, under the Prescriptions Section
Ask your doctor to fill out our prescription form. We have both a standard prescription form and an EPAP prescription form.

For more information on prescriptions, please see our Prescription Section of the Learning Center.

What does a BiPAP prescription need to say?

A BiPAP prescription must contain all of the following information:

One of the following words or phrases: "BiPAP", "BiLevel", "VPAP"
Your physician's contact information
Your physician's signature
The patient's full name
Your inspiration pressure (Also called IPAP or breathing in pressure)
- Example: IPAP 13 CM/H20
- Example: IPAP 13
- Example: IPAP 4 CM/H20
- Example: IPAP 4
Your expiration pressure (Also called EPAP or breathing out pressure)
- Example: EPAP 13 CM/H20
- Example: EPAP 13
- Example: EPAP 18 CM/H2O
- Example: EPAP 18

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:

What are the benefits of using a humidifier?

Many CPAP users experience nasal congestion and dryness of the nose and throat during treatment. This can be especially problematic for new users who are adapting to treatment. Humidification adds moisture to the air helping to reduce the symptoms of dryness and congestion.

Nasal congestion also leads to mouth breathing, which perpetuates the problem of dryness. If this is an issue for you, try a heated humidifier.

What is an integrated humidifier?

An integrated humidifier is used with a specific CPAP and fits directly onto the machine. For most heated humidifiers, this design eliminates the need for a second hose as well as a second power cord.

An advantage of an integrated humidifier is that it works very closely with the CPAP machine to deliver humidification. Also, an integrated humidifier is a compact unit that uses fewer parts to provide moisture to the user.

A disadvantage of the integrated humidifier is the user will receive less moisture when it is used with a passover humidifier. The smaller surface area effects the amount of moisture produced. Also, a integrated humidifier will only function with the CPAP for which it was designed.

You can see if your machine has an integrated humidifier option by reviewing our Compare Charts.

An example of an integrated humidifier is the PR System One Heated Humidifier as seen below attached to a machine in the PR System One line.

Here are some of the integrated humidifiers we carry:

DreamStation Heated Humidifier
Transcend Heated Humidifier
IntelliPAP 2 Heated Humidifier with Pulse Dose Humidification
PR System One 60 Series Heated Tube Humidifier with Heated Tube

What is a built in humidifier?

A "built in" humidifier is designed as a part of the CPAP machine and cannot be removed or separated from the CPAP machine. As with an integrated humidifier, the design eliminates the need for a second hose or power cord. The water chamber can be removed for cleaning or replacement purposes.

The advantage of a "built-in" humidifier is its compact shape, which operates on fewer parts. This integrated design helps to ensure optimum moisturized comfort and effectiveness when CPAP therapy and humidification are used together. Also, it allows an option for the humidification to be turned off while the CPAP is blowing.

A disadvantage is that a built in humidifier may produce less moisture if used as passover because the surface area is typically smaller. Also, since the humidifier is "built in" to the machine, detaching it is not an option. This can be an issue for frequent travelers. Lastly, if the machine or humidifier stops working, the entire unit must be sent in for repair or replacement, not just the component that failed.

An example of a machine with a built in humidifier is the ICON Auto CPAP Machine with Built In Heated Humidifier and SensAwake as seen below.

Here are some other machines we carry with built-in humidifiers:

AirSense™ 10 CPAP Machine with HumidAir™ Heated Humidifier
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier

Verified purchase | Oct. 13, 2009 | Verified CPAP.com Customer

I have been on Cpap/Bipap for 8 years+. I had another failure of my Respironics BiPap again contacted the company the sold me it and the gave me a loaner the M series unit. I got back my machine only to have it fail again. I ordered this machine that I have been on for the End of August. This is the best machine I have ever used. Smooth air flow does not stop before you finish inhaling. I have had more steady sleep in years. Even if I wake up I am back to sleep in minutes I would recommend this machine over Respironics any day. The best I have tried.

Sandman Duo BiLevel

Verified purchase | Jun. 18, 2009 | Verified CPAP.com Customer

The Sandman Duo is a very quiet and effective BiLevel. It takes up very little space on my nightstand. I am sleeping much better than with the Puritan 425 BiPaP. I hope the build quality is equal to the machine's performance.
