consecutive breaths. This can occur due to changes in the patient’s status,
where the patient attempts to inhale more gas than what is currently set. When
this occurs, the user should note if the patient is breathing or fighting with the
ventilator. The user should increase the flow rate (by decreasing the inspiratory
time) and/or reduce the rise time. The physician should be consulted.
Mitigation/Info: Patient May be Breathing with the Ventilator, Increase I
Time and/or Decrease Rise Time, Check Patient and Circuit for Leaks,
Disable Alarm, **Consult Physician**
