    Product Features

    The AirCurve™ 10 S BiLevel Machine with HumidAir™ Heated Humidifier operates on a set, higher pressure for inspiration and a set, lower pressure for expiration. The machine's comfort features are designed to help the user adjust to the two delivered pressures. This is a bilevel machine delivering one pressure for inhalation and one for exhalation while monitoring the length of the breaths and responding to alter the timing as needed to maintain the respiratory cycle.


    • Easy-Breathe Comfort Feature
    • Built-In HumidAir™ Heated Humidifier
    • TiControl and Adjustable Rise Time
    • LCD Displays with My Options
    • Enhanced Vsync Technology
    • SmartStart / SmartStop
    • SD Card and Data Storage

    Easy-Breathe Comfort Feature

    The Easy-Breathe feature on the AirCurve™ 10 S is designed to imitate a more natural breathing pattern. At the point of transition between the two pressures, a waveform of increasing and decreasing pressure is released to encourage a natural resting breath.

    Built-In HumidAir™ Heated Humidifier

    The AirCurve™ 10 S has a fully integrated humidifier built-in to the machine to supply moisture and a warmer temperature throughout the hose to increase therapy comfort. Using the My Options screen on the machine, the humidification level is easy to set. Numbers 1 through 8 are listed on the screen, 1 represents the lowest level of humidification, and 8 represents the highest. The humidifier is not required for therapy, so it may be turned off if it is not desired.

    The addition of the OPTIONAL ClimateLineAir™ heated tube assists in maintaining the warm temperature throughout the hose to prevent Rainout as the environmental temperature changes.

    TiControl and Adjustable Rise Time

    The TiControl feature on the AirCurve S machine monitors the pattern of inhalation and exhalation, comparing it against the TiMax and TiMin settings on the machine. Those with respiratory disorders such as COPD or obstructive lung disease may experience early or delayed changes from inspiration to expiration, referred to as cycling. The 10 S BiLevel TiControl feature is designed to prevent cycling by setting a minimum and maximum time limit on inspiration. When the machine detects the user breathing which falls outside the machine settings, it will intervene to alter the timing of the delivered IPAP (inhalation) or EPAP (exhalation) pressure.

    TiControl Settings:

    • Ti Max: Maximum length of Inhalation
    • Ti Min: Minimum length of Inhalation
    • Trigger: Sensitivity level for inhalation trigger
    • Cycle: Sensitivity level for exhalation

    Adjustable rise time is similar to TiControl. Both features support the user's ability to breathe at the appropriate time. Rise time is designed for this bilevel machine to increase the range of time from expiration to inspiration based on the set time requirement. Please Note: The rise time should not exceed the time set for inspiration due to a required higher pressure at inhalation.

    IMPORTANT FUNCTION NOTE: The AirCurve 10 S machine does spontaneously regulate the breathing pattern to avoid cycling which results in inefficient breathing. This machine DOES NOT deliver a breath on a timed basis. This machine is NOT a BiLevel ST machine and DOES NOT have a back up rate setting.

    LCD Display with My Options

    The AirCurve™ 10 S BiLevel has a color LCD display. The menus are designed to be easy to read and use. Select the menu item on the screen by turning the easy grip dial. Select the My Options menu to view and modify the current settings:

    • Ramp time - Ease into therapy with a period of lower pressure, or select AutoRamp™ allowing the machine to sense and adjust when sleep begins.
    • Humidity Level - Set humidity between 1 (lowest) & 8 (highest), or turn it off.
    • Mask Fit - Runs a seal integrity check showing a green smiling face for a good fit or red frowning face for a poor fit.
    • Leak Alert- Set the device to begin beeping when a large leak is detected or the mask is removed.
    • SmartStart™ - Therapy automatically starts when it senses breathing.
    • SmartStop™ - Therapy automatically stops when the mask is removed.
    • Mask Type - Set the mask type being used: Nasal; Nasal Pillow; Full Face Mask.
    • Run Warmup - Preheat the humidifier water before starting therapy.

    Enhanced Vsync Technology

    If changes occur in mask pressure or the seal of the mask, Vsync technology is established to quickly detect the leak. Vsync leak management is developed by ResMed to track and control leakage and to relay accurate data in the instance that a leak arises. The goal is to provide the user with a factual estimation of airflow. Likewise, the differences in lung capacity can be determined by the Trigger and Cycle Sensitivity feature. The level selected reflects the respiratory effort of the user.

    SmartStart™ / SmartStop™

    The intuitive AirCurve™ 10 S SmartStart™ component automatically starts the device when the user breathes into the mask. The SmartStop™ component stops the device when the user removes the mask.

    SD Card and Data Storage

    The AirCurve™ 10 S BiLevel records the information about the sleep therapy, which can be downloaded onto an SD Card. The SD Card is installed in the machine at the time of shipment and must be in the machine before it is used. The machine's on board memory holds compliance information for 365 sessions of use as well as detailed data for 30 sessions.

    Important Tips

    FAA Compliance Letter: To view the FAA compliance letter for the AirCurve™ 10 S BiLevel Machine with HumidAir™ Heated Humidifier, click here.


    This is a bilevel machine. It delivers one set pressure for breathing in (inhalation) and another separate pressure when breathing out (exhalation). The machine is designed to monitor for instances of the inhalation time being too short or too long and compare it against the TiControl settings of the machine. When the machine detects a breathing pattern which is outside of the setting parameters it responses in one of two ways:

    1. If the user attempts to inhale for longer or shorter than the settings the machine will intervene by beginning the set EPAP (expiration) pressure.
    2. If the user attempts to exhale for a longer or shorter time than the settings of the machine, it will intervene and begin, or deny, the IPAP (inspiration) pressure until it is called for by the settings.

    This machine is NOT a BiPAP ST. This machine does NOT offer Spontaneous and Timed responses to breathing events. This machines ONLY offers Spontaneous responses to inhalation breaths being too short or too long. This machine will not serve the needs of a person who has been prescribed to used a BiPAP ST or BiLevel ST or Spontaneously and Timed BiPAP. This machine CANNOT be purchased using a prescription written for a BiPAP ST machine.

    Travel Bag Tips

    As of early 2015, the AirCurve™ 10 S BiLevel Machine with HumidAir™ Heated Humidifier comes with an upgraded travel bag. The improved design is bigger, measuring 13.24 in long, 12 in wide, and 5 in tall. The larger space allows the user to pack and protect their machine as well as the accessories for the machine, such as a mask. There is a zippered compartment located between the lid and the base of the bag. The included SlimLine™ hose is located in this compartment. An image of a hose is placed along the compartment to note it is the location where the user can safely store the hose. Additional images are placed on the flap near the edge of the bag. These pictures signify the designated location for the power cord and the mask.

    Humidifier Tips

    Do not fill the water chamber past the maximum fill line as this could result in water entering and damaging the device. After use, allow the water chamber to cool for ten minutes before handling as it could be too hot to the touch. The machine will display a blue snowflake in the upper right of the screen while cooling is taking place. The water chamber should be washed weekly using warm water and a mild detergent, it should be rinsed well, and allowed to dry out of direct sunlight. The standard water chamber included IS NOT dishwasher safe and should only be hand washed. To view a dishwasher safe chamber, see the Dishwasher Safe Water Chamber for AirSense™ 10 and AirCurve 10 Humidair™ Heated Humidifier.

    If the integrated heated humidifier is not being used, purchase the Side Cover for AirSense™ 10, AirStart™ 10, and AirCurve™ 10 Machines separately in order to enclose the machine opening. The side cover is not needed to operate the machine.

    How to Determine if the Water Chamber is Dishwasher Safe?

    AirSense™ 10 and AirCurve™ 10 machines denote the water chamber model with an "S" or "C" label. Look directly above the maximum fill line located on the side of the chamber to find the word HumidAir™ and the corresponding letter embossed into the tank.

    • If the water chamber is dishwasher safe, the chamber will appear as HumidAir C, which represents a cleanable tank.
    • If the water chamber is the standard model, the chamber will appear as HumidAir S, which represents a standard tank.

    Hose Tips

    Either a 15mm (Slim) hose or a 22mm (Standard) hose may be used with the AirCurve™ 10 line of machines. The machine must be changed to the proper setting to ensure accurate therapy pressure. Also available is the optional ClimateLineAir™ heated hose which will instantly activate the Auto Climate Control feature when connected to the machine.

    A SlimLine™ hose is included with the purchase of the AirCurve™ 10 S BiLevel machine. The hose is found in the interior, zipped compartment of the travel bag. The zippered nook is located at the point where the cover meets the bottom of the travel bag at the back of the machine compartments.

    Tube Brush Compatibility with ClimateLine Hoses

    The Tube Brush Second Gen is not compatible with the following tube brands:

    • ClimateLineAir™ Heated Tube for AirSense™ 10 and AirCurve™ 10 Machines
    • ClimateLineAir™ Oxy Heated Tube for AirSense™ 10 and AirCurve™ 10 Machines

    While the tube brush can certainly be used to clean these hose models, it's not able to make the 90-degree turn at the machine connection end and will be unable to clean the entire hose. The tube brush is fully compatible with all other hoses.

    Health Tips

    ResMed's AirCurve™ 10 S has exciting technological advances to improve sleep therapy. Though, some health conditions may defer progress for some users.

    • Lung disease
    • Collapsed lung
    • Air leaking into the thorax, near the heart
    • Consistently low blood pressure, particularly due to the volume of blood in the user's circulatory system
    • Dehydration
    • A fluid leak in the brain or spine
    • Brain surgery or trauma to the brain

    AutoRamp™ Tips

    The AirCurve™ 10 S BiLevel machine feature AutoRamp™ technology. Unlike traditional ramp features that will slowly ramp up pressure over a set amount of time, AutoRamp™ will remain at the set starting pressure until it senses the user is asleep. The default starting pressure is 4 cm H2O. Once the user is asleep, the machine will start ramping 1 cm H2O per minute until it reaches the full prescribed pressure. AutoRamp™ will always reach the full prescribed pressure within 30 minutes, even if the user is not asleep, the machine will start to ramp in 1 cm H2O increments every minute to reach the full prescribed pressure at the 30 minute mark. Additionally, the AirCurve™ 10 S BiLevel machine can be set to a traditional ramp if needed, or turned off altogether.

    SmartStart™ Tips

    Per the manufacturer, the SmartStart™ technology may not function as intended when used with a nasal pillow mask and a pressure setting of 7 cm H2O or less. If the feature does not appear to be functioning, this comfort feature can be turned off. Please refer to the User Guide for more information.

    Airplane Mode Tips

    PLEASE NOTE: The AirCurve™ Line of machines include a built-in wireless modem giving the machine data transfer capabilities over a wireless cellular network. The wireless modem will automatically connect if the machine's "Airplane Mode" is turned to "Off". For privacy concerns, ships the machine with Airplane Mode "On" so that sleep data information will not be transmitted unintentionally over the wireless network. If Airplane Mode is turned "Off", sleep data could be transmitted to ResMed's servers.

    PLEASE NOTE: The AirView data transfer system is for use only in North America. It cannot be used to transmit data wirelessly outside of North America. The SD card that accompanies the machine can be used to store and share data.

    SD Card Location

    The included SD card comes installed in the machine ready to use. While looking at the machine with the display facing forward, the SD card is located under the upper flap with the white "SD" logo on the left side of the machine.
