  • The small long-lasting battery is easy to charge and replace
  • Easy to read display located in clear view on top of the unit

  • The alarm system keeps track of multiple key functions to warn users of any issues
  • autosat feature measures breath rate in real-time and automatically adjusts the amount of oxygen delivered so the user can be certain to receive the prescribed dose every minute without interrupting the activity
  • ultrasense sensitive breath detection technology identifies even the faintest breaths to automatically trigger delivery so the user never misses a breath next. If the unit detects no breath from the user the auto dose feature automatically delivers oxygen pulses until the unit detects a normal breathing pattern
