This manual is intended for the Clinician and home care Provider. Under no circumstances should it be
provided to the patient.
Safety Precautions
WARNING:
This signals a risk of injury or accident to the patient.
Pay attention to the Safety Precautions indicated in the DreamStar™ Patient Manual.
Refer to the Patient Manual for all information relating to installation, maintenance and storage of the device.
Without exception, be sure to supply the patient with the Patient Manual and accessory use instructions.
Use only the accessories that the manufacturer has authorised for use with this device, as listed in this
manual.
During treatment, only equipment included in the List of authorised accessories should be connected to the
device USB connector.
To ensure that maintenance is performed correctly and to avoid any possibility of damage, only qualified
personnel are permitted to perform maintenance on the device and make authorised changes to it. The user
assumes full responsibility for any device malfunction that results from the device being maintained by
personnel other than personnel authorised.
Never use the device without making sure that an air intake filter is installed.
If you observe any anomaly in the device, do not begin treatment.
The swivel outlet elbow, 70° 22 mm diameter, is an accessory intended for single patient use.
WARNING: Portable RF communications equipment (including peripherals such as antenna cables and
external antennas) should be used no closer than 30 cm (12 inches) to any part of the DreamStar™ product
range devices, including cables specified by the manufacturer. Otherwise, degradation of the performance of
this equipment could result.
In the following cases where the device is equipped with a water chamber:
In case of heated humidification feature use, the cover must be removed and replaced by a water chamber.
When the heated humidification feature is enabled on a device equipped with a water chamber, the patient
must take, precautions to eliminate the risk of introducing water into the device and causing irreversible
damage to it. The device must be positioned on a stable horizontal surface and must not be tilted.
The water chamber should always be emptied before moving or transporting the device.
CAUTION:
This indicates that there is a possibility of material damage to this device or
any other device.
If the device is equipped with a cover where the water chamber should be, the heated humidification feature
must be disabled. Otherwise, the device may apply the heat setting. However, there would be no risk as the
device would not reach high temperatures. If you are unsure, check the Service menu to confirm that the
heated humidification feature is disabled.
Since DreamStar™ devices are medical electrical devices, instructions concerning electromagnetic
compatibility indicated in this manual should be followed during installation.
Like all medical electrical devices, the DreamStar™ product range device is vulnerable to interference from
mobile and portable radiofrequency communication equipment (mobile phones, Wi-Fi…).
The DreamStar product range device has to be controlled to check the proper operation, whenever it is
located near to a AM, FM or broadcast antennas.
After storing or transporting the device, ensure it is used in compliance with the conditions of use specified
in this manual.
Intended use
The DreamStar™ product range devices are intended to treat patients suffering from Obstructive Sleep
Apnea Syndrome (OSA) in patients over 30 kg (66 lbs.) and breathing spontaneously. They can be
used in Home Healthcare Environment or in a sleep center.

DreamStar Intro, Info, Auto Before you start 5
The DreamStar™ device is not suitable to be used in close proximity to CT scanners, MRT devices, RF
surgical devices or in transportation vessels (on land, sea or in the air).
NOTE: The EMISSION characteristics of this device allow the machine to be used in industrial zones
and in healthcare centres (class A defined in the CISPR 11). When it is used in a residential area (class
B defined in the CISPR 11 is normally required), this device may not provide enough protection for
communication services with radio frequencies. Users may have to take certain measures, such as
the repositioning or the reorientation of the device in order to correct for this.
Contra-indications
Studies have shown that the use of positive pressure is contra-indicated in some patients affected by
any of the following pre-existent pathologies:
Severe bullous emphysema or emphysema previously complicated by pneumothorax.
Pneumoencephalus, trauma or recent surgery with sequela of cranio-nasopharyngeal fistula.
Decompensated cardiac insufficiency or hypotension, particularly in case of decreased blood
volume or cardiac arrhythmia.
Dehydration.
Massive epistaxis or history of massive epistaxis. Acute sinusitis, otitis media, or perforated
tympanic membrane.
Tracheotomy.
In addition, because positive pressure is known to affect cardiac output in certain patients, patient
arterial pressure and heart rate should be closely monitored when starting treatment at an effective
pressure. The risks and benefits of treatment by Continuous Positive Airway Pressure (CPAP) must be
weighed case by case in such subjects. This evaluation should take into account the fact that the
DreamStar™ device can be set to deliver pressures up to 20 cmH2O and, under certain fault conditions,
static pressures up to 30 cmH2O are possible. The DreamStar™ device therefore should not be used if
such pressure levels pose a risk to the patient.

WARNING: Use of cables, transducers and accessories other that those specified, may result in increased
electromagnetic emissions or decreased electromagnetic immunity of the DreamStar™ product range
devices and result in improper operation.

DreamStar Intro, Info, Auto Available Features 7
Available Features
The DreamStar™ Intro and DreamStar™ Info devices operate in continuous mode (CPAP), i.e. the device
delivers a constant pressure level.
The DreamStar™Auto device operates in either constant mode (CPAP) or in automatic mode (Auto-
CPAP), i.e. the pressure fluctuates between a minimum pressure and a maximum pressure as a
function of respiratory events detected.
The first 5 minutes of operation of the device are not included in the ramp time or latency time. During
this time, depending on the device in question, compliance and AutoCPAP features are unavailable.
Heated Humidification feature available on Evolve models
The DreamStar™ Intro Evolve, DreamStar™ Info Evolve and DreamStar™ Auto Evolve devices can be
delivered either with a cover or with a water chamber. These devices are equipped with a heated
humidification feature which you can enable or disable.
The heated humidification function is enabled on the devices delivered with a water chamber and it is
disabled on the devices delivered with a cover.
If the device is equipped with a cover and if you want to use the heated humidification feature, it is
necessary to order a water chamber and to proceed as follows:
1. Remove the cover from the device and replace it with the water chamber by referring to the Patient
Manual.
2. Enable the heated humidification function by referring to Item 4 of the Service menu in the settings
procedure of the device concerned page 18, 22 or 28.
Pressure Alter
You can enable this feature which provides the option to the patient to change the prescribed pressure
by 1 cmH2O.
Note:
This feature is only available in CPAP mode.
Auto ON feature
Functionality allowing to automatically start the treatment without pressing the device On/Off button.
Mask unplugged feature
If the patient removes his mask, the device automatically switches to low power. The machine will
restore normal power when the mask is reconnected or if the On/Off button or the ramp button
is pressed. Otherwise, the device will stop after 30 minutes.
Note:
If the patient uses a resistive interface (full face mask with anti-asphyxia valve), a specific calibration of the
pneumatic configuration must be carried out so that the DreamStar ™ unit detects that the mask is
unplugged.
Patient reminders
The DreamStar™ device has a patient reminder feature to help the patient remember key events such
as filter and mask changes, device inspections, and memory card compliance data downloads on the
memory card. This feature is described under “Reminders about key events”, on page 32.

8 Available Features DreamStar Intro, Info, Auto
Comfort Calibration
Available on DreamStar™ Info / Info Evolve and DreamStar™ Auto / Auto Evolve , the (C.C.+) Comfort
Calibration feature is intended to increase the treatment pressure during inspiration and to decrease it
during expiration to make the patient's breathing more comfortable during the treatment. It can be
enabled continuously or during the ramp.
Ramp feature
Whatever the type of ramp used, the ramp feature can be stopped during device operation by pressing
the ramp button for 2 seconds. It can be reactivated by stopping and restarting the device.
The comfort pressure, the ramp time (only if the time ramp is selected and if comfort pressure <
prescribed pressure) and the maximum ramp time can be adjusted.
Time ramp
The Time Ramp feature (T.Ramp) allows for a gradual rise in pressure to help the patient go to sleep.
When it is programmed (ramp time 0), it will be automatically activated at the beginning of the
session at comfort pressure.
In CPAP mode, the treatment begins at a reduced pressure called comfort pressure, then the pressure
increases to treatment pressure.
In Auto-CPAP mode, the Ramp feature delays the commands to raise or lower the pressure. If the
comfort pressure is lower than the minimum pressure, the gradual rise in pressure will be made from
the comfort pressure to the minimum pressure during the ramp time.
Ramp feature in CPAP mode

DreamStar Intro, Info, Auto Available Features 9
Indexed Ramp
Available on DreamStar™ Info / Info Evolve and DreamStar™ Auto / Auto Evolve, the Indexed Ramp
feature (I.Ramp) allows to start the treatment at the adjustable comfort pressure, then to have a rise in
pressure in CPAP mode or the activation of the Auto-CPAP as soon as the device starts to detect
respiratory events which indicate that the patient is asleep.
If the end of the indexed ramp is not detected before the value of the set maximum ramp time, it will
automatically stop.
The table below lists the different cases of the indexed ramp operation in CPAP or Auto-CPAP mode.

10 Device Settings DreamStar Intro, Info, Auto
Device Settings
The adjustment of the therapeutic pressure must be determined by the prescribing physician for each
patient individually, with the configuration of the equipment to be used, including the accessories. The
correct installation and positioning of the patient interface constitute a critical condition for the proper
operation of the device.
The most recent compliance data are recorded by session in the device memory within one year and 8
hours usage day, and they can be retrieved for analysis using DreamStar™ Analyze software.
The settings are accessible directly on all the devices. You can also adjust the settings of the
DreamStar™ Info, DreamStar™ Info Evolve, DreamStar™ Auto and DreamStar™ Auto Evolve using the
DreamStar™ Analyze software on a computer connected via a RS232 or Mini USB cable, or via a
wireless connection
WARNING
Before changing the device settings, confirm that the device delivers sufficient airflow when it is in operating
mode. If it does not, stop immediately and contact the technical support.
