The UAM was especially designed for use in environments where unreliable electrical power and the lack of compressed oxygen are common problems.

Here we explain how the UAM works when there is no source of compressed oxygen, when there is no electrical power, and when both of these conditions are present at the same time.

When there is no source of compressed oxygen

  • Oxygen is obtained from the UAM’s built-in concentrator
  • The function of the ventilator is not affected

When there is no electrical power

  • The oxygen concentrator will turn off
  • Oxygen is obtained from the pipeline or a cylinder
  • The UAM’s oxygen monitor is powered by the internal battery for up to 10 hours
  • The ventilator runs on battery power for up to 6 hours
  • After the ventilator battery is depleted, the user can switch to the manual bellows

When there is no electrical power and no source of compressed oxygen

  • The oxygen concentrator will turn off
  • The UAM’s oxygen monitor is powered by the internal battery for up to 10 hours
  • Room air (21% oxygen) is entrained automatically to support breathing
  • The ventilator runs on battery power for up to 6 hours
  • After the ventilator battery is depleted, the user can switch to the manual bellows
