I never used a heated tube before with my previous Respironics M-Series Auto BiPAP machine. With my old machine and tubing, I not infrequently experienced "rainout" and either had to turn up the heat in my bedroom or apply a cylindrical "blanket" around the tube to prevent this phenomenon. Having used this new tube for the past 10 days, I am pleased to report that rainout is no longer an issue with this Philips Respironics DreamStation heated tube!
The tube connects easily to the swivel outlet port on top of the Philips Respironics DreamStation humidifier and receives power from the same circuit that supplies the DreamStation PAP machine and humidifier. Another thing I really like about this tube is that it seems to be much lighter and more flexible than the rather rigid standard tubes I had been using. I am no longer bothered by the tube brushing up during the night against my face.
If you have a DreamStation humidifier, this is an excellent addition to the system to help you get a good night's sleep.
