Therapy Information
The following modes are available on the AirSense 11 device:
Device
Modes available
AutoSet
AutoSet for Her
CPAP
AirSense 11 AutoSet
AirSense 11 CPAP
AirSense 11 Elite
AutoSet mode
The treatment pressure required by the patient may vary due to changes in sleep state, body position and
airway resistance. In AutoSet mode, the device provides only that amount of pressure required to maintain
upper airway patency.
The device analyzes the state of the patient’s upper airway on a breath-by-breath basis and delivers
pressure within the allowed range according to the degree of obstruction. The AutoSet algorithm adjusts
treatment pressure as a function of three parameters: inspiratory flow limitation, snore, and apnea.
Normal airway
When the patient is breathing normally, the inspiratory flow measured by the device as a function of time
shows a typically rounded curve for each breath.
Flow limitation
As the upper airway begins to collapse, the shape of the inspiratory flow-time curve changes. The
AirSense 11 recognizes and treats traditional as well as less common flow-limited breath wave forms.
6
Snore
Snoring is sound generated by vibrations of the walls of the upper airway. It is often preceded by flow
limitation or a partial obstruction of the airway.
Apnea
The enhanced AutoSet algorithm detects both obstructive and central apneas. If an apnea occurs, the
device responds appropriately.
Obstructive apnea
An obstructive apnea is when the upper airway becomes severely limited or completely obstructed.
AutoSet generally prevents obstructive apneas from occurring by responding to flow limitation and snoring.
If an obstructive apnea occurs, the device will respond by increasing pressure.
Central apnea
During a central apnea, the airway will remain open, but there is no flow. When a central apnea is
detected, the device responds appropriately by not increasing pressure.
English 7
AutoSet for Her mode
AutoSet for Her mode is based on key aspects of ResMed’s AutoSet algorithm and delivers therapeutic
responses tailored to the characteristics of female OSA patients.
The AutoSet for Her is similar to ResMed’s AutoSet algorithm with the following modifications:
• Reduced rate of pressure increments designed to help prevent arousals.
• Slower pressure decays.
• Treats apneas up to 12 cm H
2
O (12 hPa) and continues to respond to flow limitation and snore up to
20 cm H
2
O (20 hPa).
• Minimum pressure (Min. Pressure) that adjusts according to the frequency of apneas:
If two apneas occur within a minute, the pressure reached in response to the second apnea will
become the new minimum treatment pressure until the next treatment session.
Patients who use AutoSet for Her will still get the benefits of ResMed's AutoSet technology including
improved sensitivity to flow-limitation and Central Sleep Apnoea Detection with Forced Oscillation
Technique.
CPAP mode
In CPAP mode, a fixed pressure is delivered—with optional Expiratory Pressure Relief (EPR
™
).
Reporting
The AirSense 11 reports Respiratory Effort Related Arousals (RERA), and detects Central Sleep Apnea
(CSA) and Cheyne-Stokes Respiration (CSR). The summary and detailed data of these parameters are
available to view on ResMed's patient compliance software (data availability depends on device mode and
parameter measured).
Central sleep apnea detection
Available in all modes on the AirSense 11 AutoSet and the AirSense 11 Elite.
The device detects both obstructive and central sleep apneas (CSA). CSA detection uses the Forced
Oscillation Technique (FOT) to determine the state of the patient’s airway during an apnea. When an apnea
has been detected, small oscillations in pressure [1 cm H
2
O (1 hPa) peak-to-peak at 4 Hz] are added to the
current device pressure. The CSA detection algorithm uses the resulting flow and pressure (determined at
the mask) to measure the airway patency.
8
Cheyne-Stokes respiration detection
Available in all modes on the AirSense 11 AutoSet and the AirSense 11 Elite.
Cheyne-Stokes respiration (CSR) is a form of sleep-disordered breathing characterized by a periodic waxing
and waning of respiration. The waxing periods (hyperpneas, typically 40 seconds in length) can include
large gasping breaths that tend to arouse the patient while the waning periods (hypopneas or apneas,
typically 20 seconds in length) cause blood oxygen desaturations.
The following example shows a typical CSR period.
The following example suggests periodic breathing due to the frequently occurring apneas. However,
when looking closely at the shape of the hyperpneas it can be seen that it is a typical OSA period.
The AirSense 11 device reports the time during therapy in which it detected breathing patterns indicative
of CSR. It analyzes the patient's respiratory flow for apnea/hypopnea events, calculates the time between
these events, and characterizes the shape of breathing between them.
English 9
Respiratory effort related arousals reporting
Respiratory Effort Related Arousals (RERA) reporting is available on the AirSense 11 AutoSet and AirSense
11 Elite in all modes.
RERAs are periods of increasing respiratory effort which are terminated by an arousal. Increasing
respiratory effort will be seen as airflow limitation.These flow-based RERA events are logged and stored as
summary and/or detailed data and can then be viewed in one of ResMed's patient management systems.
Comfort features
Ramp
Designed to make the beginning of treatment more comfortable, ramp is available in all modes.
In AutoSet and AutoSet for Her mode, ramp time defines the period during which the pressure gradually
increases from a lower more comfortable start pressure to the minimum treatment pressure before the
auto-adjusting algorithm commences.
In CPAP mode, the pressure increases from a low pressure (Start Pressure) to the prescribed treatment
pressure.
Ramp Time can be set to Off, 5 to 45 minutes or Auto. When Ramp Time is set to Auto, the device will
detect sleep onset and then gradually increase from the start pressure to the minimum treatment pressure
at a rate of 1 cm H
2
O (1 hPa) per minute. However, if sleep onset is not detected, the device will reach the
target pressure within 30 minutes.
Expiratory Pressure Relief
Designed to make therapy more comfortable, Expiratory Pressure Relief (EPR) maintains optimal treatment
for the patient during inhalation and reduces the delivered mask pressure during exhalation.
EPR On—EPR is enabled.
Off—EPR is disabled.
The following settings are only available if EPR is On:
EPR Type
Full Time—If set to Full Time, EPR is enabled for the whole therapy session.
Ramp Only—If set to Ramp Only, EPR is only enabled during ramp time.
EPR Level
1, 2, 3 cm H
2
O (1, 2, 3 hPa)
When EPR is enabled, the delivered pressure will not drop below a minimum pressure of 4 cm H
2
O
(4 hPa), regardless of the settings.
10
AutoSet Response
AutoSet mode (AirSense 11 AutoSet device only).
For patients who are sensitive to faster changes in pressure during therapy, AutoSet Response can be set
to either Standard or Soft. If set to soft, patients will receive gentler pressure rises during therapy.
Patients who use the AutoSet Response feature will still get the benefits of ResMed's AutoSet technology
including improved sensitivity to flow-limitation and CSA Detection with Forced Oscillation Technique.
About the heated tubing
The ClimateLineAir 11 is a heated breathing tube that delivers air to a compatible mask. When used with
the device humidifier tub, ClimateLineAir 11 heated air tubing allows you to use the Climate Control
feature.
Note: Not all types of air tubing are available in all regions.
Climate Control
Climate Control is an intelligent system that controls the humidifier and the ClimateLineAir heated air
tubing. This feature:
• delivers comfortable humidity level and temperature during therapy
• maintains the set temperature and relative humidity during sleep to prevent dryness in the nose and
mouth
• can be set to either Auto or Manual
• is only available when both the ClimateLineAir 11 and HumidAir 11 tub are attached.
Climate Control - Auto setting
Auto is the recommended and default setting. It is designed to make therapy as easy as possible so there
is no need to change the temperature or humidity settings.
• Sets the tube temperature to Auto (80ºF/27ºC). If the air in the mask is too warm or too cold, you can
adjust the tube temperature to anywhere from 60 to 86ºF (16 to 30ºC) or turn it off completely
• Adjusts the humidifier output to maintain a constant, comfortable humidity level of 85% relative
humidity
• Protects against rainout (water droplets in the heated air tubing and mask).
Climate Control - Manual setting
Manual is designed to offer more flexibility and control over settings and offers the following:
• Temperature and humidity can be adjusted to find the most comfortable setting
• Temperature and humidity level can be set independently
• Rainout protection is not guaranteed. If rainout does occur, first try increasing the tube temperature
• If the air temperature becomes too warm and rainout continues, try decreasing the humidity.
Notes:
• If Climate Control is set to Manual, the Auto Tube Temperature setting is not available.
• The temperature and humidity settings are not measured values.
Tube Temperature
The temperature sensor located at the mask end of the ClimateLineAir 11 heated air tubing enables the
system to automatically control the temperature of the air delivered to the patient. This ensures the
temperature of the air delivered to the patient does not fall below the set minimum temperature, therefore
maximizing breathing comfort for the patient.
Humidity Level
The humidifier moistens the air and is designed to make therapy more comfortable.
• If the patient is getting a dry nose or mouth, turn up the humidity
• If the patient is getting any moisture in the mask turn down the humidity.
English 11
• The Humidity Level can be set to: Off or between 1 and 8, where 1 is the lowest humidity setting and
8 is the highest humidity setting.
For each humidifier setting, the Climate Control system delivers a constant amount of water vapor, or
absolute humidity (AH), to the patient's upper airway.
Automatic Adjustment
The humidifier and ClimateLineAir 11 heated air tubing are controlled by the Climate Control algorithm to
deliver constant humidity and temperature outputs. The system adjusts automatically to changes in:
• ambient room temperature and humidity values
• flow due to pressure changes
• flow due to mask or mouth leak.
12
Setting up your device
WARNING
Do not use any additives in the humidifier tub (eg, scented oils or perfumes). These may reduce
humidification output and/or cause deterioration of the tub materials.
CAUTION
Use only ResMed parts (eg, air inlet filter, power supplies), masks and accessories with the machine.
Non ResMed parts may reduce the effectiveness of the treatment, may result in excess carbon
dioxide rebreathing and/or damage the machine. For compatibility information, refer to
ResMed.com for more information.
When using the humidifier tub:
• Always place the device on a level surface, lower than your head, to prevent the mask and air
tubing from filling with water.
• Do not overfill the humidifier tub as water may enter the device and air tubing.
• Do not fill the humidifier tub with hot water as this could lead to excessive air temperature at the
mask. Ensure the water is cooled to room temperature before filling the humidifier tub.
• Do not place the device on its side while the humidifier is attached as water might get into the
device and reduce motor life.
When setting up the AirSense 11 system:
• Do not place the power supply where it can be bumped, stepped on, or where someone is likely
to trip over the power cord
• Do not block the air tubing and/or air inlet of the device while in operation as this could lead to
overheating of the device
• Keep the area around the device dry, clean and clear of anything (eg, clothes or bedding) that
could block the air inlet or cover the power supply unit
• Ensure the system is correctly set up. Incorrect system setup may result in incorrect mask
pressure reading.
When using a mask:
• Use only vented masks recommended by ResMed or by the prescribing doctor with this device
• Fitting the mask without the device blowing air can result in rebreathing of exhaled air
• Make sure that the mask vent holes are kept clear and unblocked to maintain the flow of fresh air
into the mask.
