Curasa Auto CPAP Machine Overview
Featuring a truly integrated optional heated humidifier, the Curasa Auto CPAP Machine with EUT leaves a minimal footprint for use at home or away.
The Cursa Auto is no longer available, but we recommend the DreamStation Auto with Heated Humidifier as a suitable alternative. The DreamStation Auto is one of the quietest machines on the market today. The included humidifier keeps therapy air warm and moist so that your sinuses will dry out less and you'll be more comfortable.
The Curasa Auto CPAP Machine with EUT is a sturdy machine that features modern features to make therapy more comfortable. This is an auto-adjusting machine that will adjust on a breath by breath basis to provide the optimal pressure needed.

Optional Integrated Heated Humidifier
The Curasa Auto CPAP Machine features slots on one side of the machine for the humidifier to latch in to. Rather than having a humidifier with a chamber that is taken in and out, the Curasa humidifier chamber is the humidifier. All electrical components are built in to the bottom half of the chamber. A short jumper cord attaches the humidifier to the machine making for an overall small system.
Small Design & Footprint
The Curasa Auto comes in at 7 1/8 in L x 4 5/8 in W x 3 1/2 in H, making it roughly the size of a ITEM???. With the optional humidifier attached it measures 9 in L x 7 3/4 in W x 4 in H, which will leave a relatively small footprint on a nightstand. The machine weighs 2.4 lbs alone and 3.3 lbs with humidifier and connector tube.
EUT Exhalation Relief
The Curasa Auto features EUT (Expiratory Unloading Technology) an exhalation relief function like many other popular machines. Exhalation relief can make therapy more comfortable and feel more natural. The EUT feature can be set on one of three different levels from a light amount of relief to a larger drop in pressure when exhaling. The EUT feature can also be set to 0 which turns the feature off entirely.
Advanced Data Recording
The Curasa Auto will record up to 365 nights of the following therapy information to the on-board memory and can be transferred to the included data card and viewed using the OPTIONAL AutoManager software:
- Apnea Index
- Hypopnea Index
- Snore Index
- Leak Rate
- Flow Limitation Information
Auto On / OFF Feature
The Auto On / Off feature allows the Curasa Auto to detect when the mask is on the user and he or she is breathing. The machine automatically begins providing the therapy air stream without having to press a button. This feature may be turned off if desired.
If the AUTOON feature is set to off and the mask is removed or there is a significant mask leak while the machine is blowing air, the mask off alarm will sound. The alarm can be silenced by pushing the up and down arrow keys and by turning the blower off.
Power Out Alarm
If the power goes out while the Curasa APAP machine is running, the machine sounds an alarm to notify the user of the disruption in power. To silence the alarm press the power key. The power out alarm will also sound if the power cord is disconnected from the wall outlet while the machine is running. The power out alarm function cannot be turned off.

Filter Care & Opening the Filter Cassette
- With the filter end of the machine facing you, remove the cassette from the machine by lifting the tab on the left side of the cassette.
- Once the cassette is removed from the machine hold it in front of you with the black filter facing you oriented with the long sides of the cassette parallel with your body.
- Hold the short sides of the cassette by the frame edges using both hands.
- Place the flat balls of your thumbs against the outside edges of the black filter.
- Aim the white side of the filter way from you and towards a table or bed in case the cassette back pops out with force.
- Applying even pressure with both thumbs, push with the balls of the thumbs to force the back of the cassette to pop out of the frame.
- The black foam filter should be washed weekly, allowed to dry completely and reinstalled. It should be replaced around every 6 months.
- The white fine filter cannot be washed and should be discarded and replaced monthly.
- The black foam filter goes into the cassette frame first so it will be facing the out when the cassette is reinstalled.

Curasa Machines Work with Domestic and International Voltages:
The Curasa CPAP Machine and OPTIONAL Heated Humidifier operate on 110v to 240v AC. There is no need to changes fuses or switches to operate on 240v, only an appropriate plug adapter for the country. CPAP.com offers the World Traveler Power Adapter Plugs as an option for operation in many European and Asian counties.
DC Operation With Inverter:
Want to use the Curasa machine while away from AC power? Although the Curasa machine has a DC port, at this time an appropriate DC cable is not available. CPAP.com is working to change that. This kit provides AC power to connect the Curasa's AC cord to the power inverter.
Respironics Battery Kit with 400 Watt DC to AC Power Inverter includes the 400 Watt DC to AC Power Inverter and the sealed lead acid Respironics Battery Pack.
Machine works eventually, but the instructions are totally incomprehensible. If you have a problem there is no point in looking at the manual. more...
I have used the Curasa CPAP machine on the "auto" setting (effectively used it as an APAP) for 4 nights. It is a solid, basic machine and it felt like it successfully adjusted to the pressure needed to avoid my apnea. However, although the Curasa supposedly records usage data internally, it does not display any information like a Apnea-Hypopnea Index after a night's sleep like my Resmed Airsense S10 does. That is the major reason for the 4-star rating. Supposedly you can download that information on the 2-gigabyte SD card that is provided, but to read that information on your computer you must purchase special software for an additional $30 or so. Thus, with the basic machine you get no feedback and you must already know what you are doing to use it correctly. I feel the software should at least be included with the package so that the user always has that feedback for adjusting his or her regimen for breathing therapy. Secondly , you must know if you need a humidifier or a heated air supply tube. I do not use a humidifier, but it is available as an option for an extra fee and would attach directly to the side of the basic Curasa machine. However, I do not see any provision for a heated tubing connection (as there is on the Resmed Airsense 10), so if you need a heated tubing, you should probably buy a different machine. I am curious how well the EUT adjustment for lowering the air pressure during exhalation will work as the concept seemed to be quite good, but I have not tried that feature yet. Compared to my Resmed Airsense 10 machine, I noticed that the fan blower noise coming up the hose was slightly louder and seemed to change pitch on inhalation versus exhalation, which was distracting until I got used to it . I also noticed a curious acrid odor somewhat like burnt insulation during first use although that seemed to be abating somewhat with repeated use over the nights. The intake air filter is a black cassette with a washable, coarse-weave plastic mesh as the outside layer and a fine-weave Dispoable filter on the inside, which is the same dimensions as the replacement air filters I have purchased for my Resmed S10. One such filter cassette is installed in the machine and a second such cassette is provided in the packaging. The flexible air supply tubing that comes with the Curasa seems to be a standard, non-heated , lightweight 22 mm plastic tubing with standard sized connectors at each end. Also included is a 24-volt DC power supply brick that has a figure "8" type of socket for the cord that plugs into the 120 volt AC source. Finally, the Curasa comes with a rather nice black fabric carrying case with compartments for the air hose, CPAP machine, power supply brick, and your mask. That case with all materials is about 2/3 of the size of the case for my Resmed Airsense 10, and thus I will be using this machine when I travel. Cheers! more...

Purchased for travel. A tad bit large for travel, and case is a bit big to get in suitcase. But, BIG improvement over previous travel machine. Much quieter and easier to exhale. more...

I love it. It's nicely compact. It makes a funny noise when you disconnect, I.e., getting up to the bathroom, but I just turn it off for that duration. This could be a safety feature to wake you if something disconnects during the night. I purchased the software, which will allow me to see what rates I register during the night, but I haven't connected that yet. Note of a stong plastic odor for about the first 24 hrs of use. You may want to run it during the day before use to get rid of the plastic odor. I've been using it for about 6 days and there is no longer any odor. more...
