The MediByte Jr Home Sleep Testing (HST) device provides simple, cost effective and reliable screening for sleep apnea. Constructed of smooth nylon/plastic with an extra-strength LEMO connector, the MediByte was designed for durability. Weighing less than three ounces, it is ideal for both adult and pediatric studies. Side wings attach the unit to the chest effort belt so that a holding vest or pouch is not required. On-board oximetry and internal pressure sensor eliminate external transducers.
