The Philips Respironics DreamStation™ heated tube is a replacement hose (or uprade to Standard Tubing) that is used with the DreamStation™ series heated humidifier. When the tube is connected to the humidifier, the temperature can be set from zero (off) to 5 with 5 being the highest level of humidification being applied through the hose. The temperature control allows you to personalize the humidity based solely on your environment. Some areas in the world are extremely humid meaning the need for extra humidity is not needed, however, some areas are dry climates and may increase the need for additional humidification to keep your airway moist and lubricated.
The Dreamstation™ heated tube can increase therapy comfort by helping to maintain heat and moisture delivered to the nasal cavity. Direct pressure from the Bi-Level or CPAP machine can cause dryness and the heated tubing helps reduce the chances of dryness while using the CPAP or Bi-Level.
