1.1 HUMIDIFIER SYSTEM OVERVIEW

The DreamStation Heated Humidifier attaches to the therapy device and provides an air outlet port to connect
a breathing circuit. The breathing circuit is comprised of patient tubing, a mask, and in some instances a
separate exhalation device. The patient tubing can be Respironics heated tubing, 22 mm (non-heated)
performance tubing or 15 mm (non-heated) performance tubing.

The DreamSt ation Heated Humidifie r with Heated Tubing is designed to deliver humidification to provide ad ded
comfort during therapy. This humidification level is controlled through the output of the heated humidifier as
well as the temperature of the optional heated tubing. Use of these two accessories allows for a comfortable
level of humidity to be maintained at the mask.

The DreamStation Heated Humidifier is comprised of the following components:

• Heated Humidifier - The heated humidifier is the primary source of humidification. Humidification

is controlled by adjusting the temperature of the heater plate . The heater plate is then used to hea
water

found in the water tank. This manual includes instructions that explain how to set up an

t

ake care of the heated humidifier . For instructions on how to adjust the heated humidifier settings

refer

to the instructions for use that accompanied the therapy device.

• Water Tank - The water tank stores the water that will be used by the heated humidifier . This man-

ual includes instructions that cover how to use and take care of the water tank.

• Heated Tubing - The heated tubing is an optional accessory that is used, along with the heated

humidifier
ture of the air in order to ensure that it does not cool down pr ior to reaching the mask. This manu
in

cludes instructions that cover how to connect and t ake care of the hea ted tubing. For instruction s
on how to adjust the temperature of the heated tubing, refer to the instructions for use that accom­panied the therapy device.

SmartRamp When SmartRamp mode is enabled, the therapy device’s

ramp function utilizes an Auto titrating algorithm during the
ramp period. It allows patients the ability to stay at lower
pressures during the ramp period, to improve their acclimation
to therapy.
SmartRamp mode functions differently, depending on the
therapy mode that the device is using.
*In CPAP or CPAP-Check mode, the SmartRamp applies the
Auto-CPAP algorithm during the ramp period. The Ramp Start
pressure becomes the Auto Minimum pressure during the
ramp period. The Auto Maximum pressure during ramp is the
CPAP or CPAP-Check pressure.
*In Auto mode, the SmartRamp applies the Auto-CPAP
algorithm during the ramp period. The Ramp Start pressure
becomes the Auto Minimum pressure during the ramp period.
The Auto Maximum pressure during ramp is the Auto
Minimum under normal Auto mode.
*In BiPAP or Auto-BiPAP mode, the SmartRamp applies the a
modified version of the Auto-BiPAP algorithm during the ramp
period. The Ramp Start pressure becomes the EPAP
Minimum pressure, and the Pressure Support Minimum
pressured is applied.
The IPAP Maximum pressure during ramp is the EPAP or
EPAP Minimum under normal BiPAP or Auto-BiPAP mode.
The SmartRamp period will terminate in either of two ways:

1) If SmartRamp pressure reaches the minimum pressure of
the therapy mode selected, then SmartRamp ends, and the
device continues to deliver therapy under the selected therapy
mode, or:

2) If SmartRamp pressure does not reach the minimum
pressure of the therapy mode selected by the end of the
Ramp Time, then pressure is increased at a rate of
approximately 1 cm H2O per minute. Once the pressure
reaches the minimum pressure of the therapy mode selected,
then the device will continue to deliver therapy for that mode.
If SmartRamp mode is not enabled, then the standard, linear
pressure ramp mode is active.

and statistics to help make troubleshooting over the phone easier. If there is not a modem installed in the
therapy device, you can direct the patient to read you the five codes off the Performance Check screen over
the phone. You can decode these codes in EncoreAnywhere, EncorePro or Encore Basic to populate the
troubleshooting dashboard.

4.12 BLUETOOTH WIRELESS TECHNOLOGY

The device may be equipped with Bluetooth wireless technology. If available, you can pair the therapy device
to a mobile device that has the DreamMapper app installed. DreamMapper is a mobile and web-based system
designed to help Obstructive Sleep Apnea (OSA) patients enhance their sleep therapy experience.

4.12.1 PAIRING TO YOUR BLUETOOTH ENABLED MOBILE DEVICE

NOTES

• You can only pair your therapy device to one mobile device at any given

time.

• Pairing works best when your therapy device and mobile device are in the

same room.

Follow the steps below to manually pair to your mobile phone or tablet.

1. To pair to your mobile device, first ensure that the Bluetooth setting is turned ON on your mobile
device. Refer to your mobile device’s instruction manual for more information.

2. If you need to select from a list of available Bluetooth devices, the therapy device will appear as
“PR BT XXXX” (XXXX will be the last four digits of the serial number listed on your therapy
device).

3. When your therapy device is powered up but the blower is off, initiate pairing from your mobile
device.

4. If your mobile device is in range, one of the following two steps will apply:

PAGE 4-291117539, VER. 07

• Your mobile device has Bluetooth Secure Simple Pairing (SSP)

The following icon will pop-up on your therapy device screen with a 6 digit number and “Pair?”:

This number is a six digit passkey generated during SSP. Verify that the six digit SSP passkey is the same on
both the mobile device and therapy device. Rotate the Control Dial between “yes” or “no”, and then press the
Control Dial to choose. If “no” is selected, or the pop-up screen times out after 30 seconds, the device will
reject the pair request. If “yes” is selected, the therapy device will acknowledge the six digit SSP passkey. If the
mobile device also acknowledges the request, the two will now be paired and ready to connect using
DreamMapper.

• Your Bluetooth enabled mobile device does not support Bluetooth SSP

Your mobile device will prompt you to enter a pin code. Enter “1008” on your mobile device. The following icon
will pop-up on your therapy device screen with the number “001008” and “Pair?”:

Rotate the Control Dial between “yes” or “no”, and then press the Control Dial to choose. If “no” is selected, or
the pop-up screen times out after 30 seconds, the device will reject the pair request. If “yes” is selected, the
therapy device will acknowledge the 001008 passkey. If the mobile device also acknowledges the request, the
two will now be paired and ready to connect using DreamMapper.

Note: Do NOT select “yes” on the pop-up screen unless you are currently trying to pair your devic es. This will
ensure that only your mobile device connects to your therapy device.

4.13 ACCESSORIES

There are several accessories available for the DreamStation system such as a Humidifier, Cellular Modem,
Wi-Fi Accessory or a Link Module. When using optional accessories, always follow the instructions enclosed
with the accessories.

CAUTION

Pins of connectors should not be touched. Connections should not be made to these
