    Explanation of Modes and Controls occurs when (1) the set i time elapses, or (2) Paw exceeds the Pressure Control setting by 8 cmH O (mbar). Maximum airway pressure won’t exceed the user set High P alarm setting. The target airway pressure for pressure controlled mandatory breaths in A/CMV and SIMV is the display setting above ambient pressure, not above PEEP.
  • Page 110 Explanation of Modes and Controls Backup Ventilation is not active for 60 seconds after the user adjusts ventilator controls, changes modes or starts ventilation from the Setting condition.
