1. Safety information
Intended use
The DreamStation 2 CPAP/DreamStation 2 Auto CPAP system delivers positive airway
pressure therapy for the treatment of Obstructive Sleep Apnea in spontaneously breathing
patients weighing over 30 kg (66 lbs). It is for use in the home or hospital/institutional
environment.
Important
The device is to be used only on the instruction of a licensed physician. Your home care
provider will set the correct pressure settings and will provide accessories according to your
health care professional’s prescription.
Several accessories are available to make your OSA treatment with the DreamStation 2 system
as convenient and comfortable as possible. To ensure that you receive the safe, eective
therapy prescribed for you, use only Philips Respironics approved accessories.
Contraindications
When assessing the relative risks and benets of using this equipment, the clinician should
understand that this device can deliver pressures up to 20 cmH2O. In the event of certain fault
conditions, a maximum pressure of 40 cmH2O is possible. Studies have shown that the following
pre-existing conditions may contraindicate the use of CPAP therapy for some patients:
• Bullous Lung Disease
• Pathologically Low Blood Pressure
• Bypassed Upper Airway
• Pneumothorax
• Pneumocephalus has been reported in a patient using nasal Continuous Positive Airway
Pressure. Caution should be used when prescribing CPAP for susceptible patients such
as those with: cerebral spinal uid (CSF) leaks, abnormalities of the cribriform plate, prior
history of head trauma, and/or pneumocephalus. (Chest 1989; 96:1425-1426)
The use of positive airway pressure therapy may be temporarily contraindicated if you exhibit
signs of a sinus or middle ear infection. Not for use with patients whose upper airways are
bypassed. Contact your health care professional if you have any questions concerning your
therapy.

Warnings
A warning indicates the possibility of injury to the user or operator.
Device usage This device is not intended for life support.
Contact your health care professional if symptoms of sleep apnea recur.
Personnel
qualifications
This manual serves as a reference. The instructions in this manual are not intended to
supersede your health care professional’s instructions regarding the use of the device.
The prescription and other device settings should only be changed on the order of the
supervising physician.
The operator should read and understand this entire manual before using the device.
Operating
temperature
Do not operate the device in direct sunlight or near a heating appliance because these
conditions can increase the temperature of the air coming out of the device.
Bacteria filter If the device is used by multiple persons in a hospital environment (such as rental
devices), a low-resistance, main ow bacteria lter should be installed in-line between
the device and the circuit tubing to prevent contamination.
Humidication can increase the resistance of the bacteria lter and the operator must
monitor the bacteria lter frequently for increased resistance and blockage to ensure
the delivery of the therapeutic pressure.
Improperly
functioning
device
If you notice any unexplained changes in the performance of the device, if it is making
unusual sounds, if it has been dropped or mishandled, if water is spilled into the
enclosure, or if the enclosure is cracked or broken, discontinue use and contact your
home care service provider.
Power cord Route the power cord to the outlet in a way that will prevent the cord from being
tripped over or interfered with by chairs or other furniture.
To avoid strangulation hazards, ensure that all cords connected to the device are
properly routed.
This device is activated when the power cord is connected.
Use only power cords supplied by Philips Respironics for this device. Use of power cords
not supplied by Philips Respironics may cause overheating or damage to the device.

- 3 -
Patient
circuits and
tubing
The device should only be used with compatible patient interfaces (e.g., masks, circuits
and exhalation ports). Proper operation of the device with other circuits has not been
veried by Philips Respironics and is the responsibility of the health care professional.
A mask should not be used unless the device is turned on and operating properly. The
exhalation port(s) associated with the mask should never be blocked.
Explanation of warning: The device is intended to be used with special masks or
connectors that have exhalation ports to allow continuous ow of air out of the mask.
When the device is turned on and functioning properly, new air from the device ushes
the exhaled air out through the mask exhalation port. However, when the device is
not operating, enough fresh air will not be provided through the mask, and exhaled
air may be rebreathed. Rebreathing of exhaled air can, in some circumstances, lead to
suocation.
If you are using a full face mask (a mask covering both your mouth and your nose), the
mask must be equipped with a safety (entrainment) valve.
An exhalation port is required. Do not block the exhalation port. This can reduce airow
and result in rebreathing of exhaled air.
At low expiratory pressures, the ow through the exhalation port may be inadequate to
clear all exhaled gas from the tubing – some rebreathing may occur.
Do not pull or stretch the tubing. This could result in circuit leaks.
Do not cover the tubing with a blanket or heat it in an incubator or with an overhead
heater. This can aect the quality of the therapy or injure the patient.
The device should only be used with a compatible Philips Respironics mask, as
prescribed by your Healthcare Provider.
Accessories To ensure that you receive the safe, eective therapy prescribed for you, use only
Philips Respironics accessories. The use of accessories, transducers, and cables other
than those specied by Philips Respironics may result in increased emissions or
decreased immunity of the device.
Pulse
oximeter
Use only Philips Respironics recommended pulse oximeter and sensors. Use of
incompatible sensors can result in inaccurate pulse oximeter performance.
Do not use a damaged pulse oximeter or sensor.
Before use, carefully read these instructions and the instructions for use provided with
the pulse oximeter and sensor.

- 4 -
Integrated
humidifier
For safe operation when using the integrated humidier, the device must always be
positioned below the breathing circuit connection at the mask. The device must be level
for proper operation.
Allow the heater plate and water to cool down for approximately 15 minutes before
removing the humidier water tank. A burn may result from: touching the heater plate,
coming in contact with the heated water, or touching the humidier water tank pan.
Cleaning To avoid electrical shock, always unplug the power cord from the wall outlet before
cleaning the device.
Do not immerse the device in any uids or spray the device with water or cleaners.
Clean the device with a cloth dampened with an approved cleaner.
Empty and clean the humidier water tank daily to prevent mold and bacteria growth.
Oxygen When using oxygen with this system, the oxygen supply must comply with local
regulations for medical oxygen.
Do not connect the device to an unregulated or high pressure oxygen source.
When using oxygen with this system, a Philips Respironics pressure valve must be placed
in-line with the patient circuit between the device and the oxygen source. The pressure
valve helps to prevent the back ow of oxygen from the patient circuit into the device when
the unit is o. Failure to use the pressure valve could result in a re hazard.
Oxygen supports combustion. Oxygen should not be used while smoking or in the
presence of an open ame.
Do not use the device in the presence of a ammable anaesthetic mixture in
combination with oxygen or air, or in the presence of nitrous oxide..
Do not use the device near a source of toxic or harmful vapors.
When using oxygen with this system, turn the device on before turning on the oxygen.
Turn the oxygen o before turning the device o. This will prevent oxygen accumulation
in the device. Explanation of the Warning: When the device is not in operation and
the oxygen ow is left on, oxygen delivered into the tubing may accumulate within the
device’s enclosure. Oxygen accumulated in the device enclosure will create a risk of re.
