More Information

  • Caution:
    - The Evolution is not suitable for use during sleep.
    - The Evolution is not suitable for children.
  • Function: When we breathe, approximately one-third of the time is spent inhaling, and two-thirds exhaling. As a result, oxygen delivered by continuous flow is wasted during exhalation. By eliminating oxygen flow during exhalation, a two-thirds savings is possible. Additionally, the application of the Evolution is based on the fact that only oxygen inhaled at the beginning of the breath actually reaches the alveoli and is absorbed by the body. The oxygen inhaled during the remainder of the breath is not used and is exhaled again. For this reason, the Evolution only administers oxygen at the beginning of inhalation. This makes the oxygen source last longer. The Evolution is designed to be an integral component of a lightweight, long-lasting ambulatory system.
  • Care and Maintenance: The Evolution conserver is designed for a long and accurate life, however, as with any electronic device, prudent care is required. The unit should be kept clean and free from moisture and dust, as well as extreme temperature. Do not expose the unit to water, such as when bathing or swimming. It is advisable to keep the device in a carrying bag to afford a degree of protection.
