ClimateLine OXY Heated Tubing is designed exclusively for use with ResMed's AirSense 10 Series CPAP and AirCurve 10 Series BiLevel machines. It includes a supplemental oxygen port built directly into the tube so it is an ideal solution for Sleep Therapy users who also require oxygen therapy. ClimateLineAir OXY adjusts heating and humidity throughout the night to protect against rainout and deliver constant, comfortable temperature and humidity levels. It also features a 360° swivel for increased freedom of movement without kinks or dragging.
