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. For
information related to the mask to be used, including any need for a separate exhalation device, consult the instructions for use that
accompany both the mask and therapy device.
The DreamStation Heated Humidifier with Heated Tubing is designed to deliver humidification to provide added 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 heat water found in the water tank. This manual includes
instructions that explain how to set up and take 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 manual 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, to control the
provided humidification. This is accomplished by controlling the temperature of the air in order to ensure that it does not cool
down prior to reaching the mask. This manual includes instructions that cover how to connect and take care of the heated tubing.
For instructions on how to adjust the temperature of the heated tubing, refer to the instructions for use that accompanied the
therapy device.
