ResMed introduces its new ClimateLine Heated Tubing with the S9 series machines. Exclusive to ResMed the ClimateLine Tubing is 40% lighter, 20% thinner, and takes up 35% less space. The ClimateLine Heated Tubing works in harmony with your H5i humidifier to give you measured and controlled heat and humidification at the mask, virtually eliminating rain out. (Can only be used with the Climate Control System) Providing more flexibility and less drag with light weight materials, this tubing promises to be a favorite among CPAP users. In addition to this, ResMed introduces a smart-fit cuff design that makes it easier to attach and remove the tube from your mask and machine.
