    "EUT is a very nice feature, the machine breathes with you rather than the other way around."

    "This is very nice small machine. I ordered it without a humidifier, and immediately regretted it. I ordered the humidifier unit and anxiously await its arrival."

    Product 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.

    Manufactured by Curative Medical.

    Product Features

    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.
