S9 H5i Features
With its optional ClimateLine Heated Tubing , ResMed has solved any rainout problems caused by changing temperatures in your tubing. This special tubing system adjusts the heat and humidification by the mask, allowing you to receive the exact heat and humidification that you selected on your machine. It has a thermostat at the mask end, and it will measure the temperature at the mask. If the temperature has dropped between the humidifier and the mask, the tubing will heat the air to the temperature that you selected. In this way, any problems of rainout that are so common among patients who use humidifiers, are solved.
