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.

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.

5.4 DEVICE ERROR CODES
The following table lists the error level and descriptions for the DreamStation devices.
ERROR LEVEL DESCRIPTION
STOP The error information is recorded in NVRAM and the unit is
placed into Safe State. The only functionality available to th e user is serial communication, turnin g off the audible alarm via a key press and removing power.
REBOOT The error information is recorded in NVRAM and the unit is
rebooted. The fifth occurrence of a REBOOT level error within a 24 hour period (while power is maintained), will be promoted by the system to a STOP level error.
ABORT The error information is recorded in NVRAM.The fifth
occurrence of a ABORT level error within a 24 hour period (while power is maintained), will be promoted by the system to a STOP level error. This error is similar to a Reboot-Level Error with the exception that the system is unable to handle the error prior to the reset, e.g. watchdog timeout.
