Operating the Ventilator
5-14 Operator's Manual
Backup Battery Shutdown
Imminent alarm
Internal battery system is
depleted. Connect to external
power immediately.
Minimum of 15 minutes internal
battery system use time left. Connect to external AC or DC power, and make sure that
the green external power LED lights up. Do not leave the
ventilator until you see the green light.
If no external power is available, prepare an alternate
method of mechanical ventilation immediately.
High Respiratory Rate alarm
The delivered breath rate is
higher than the alarm setting
Patient is breathing fast. Check the patient and resolve.
Auto-triggering of ventilator
caused by leak. Resolve leak in circuit by tightening all connections.
If airway leak, turn on NIV and increase bias flow setting.
The sensitivity setting for flow,
pressure trigger, or both is too
sensitive. Optimize trigger setting(s).
Double triggering caused by too
short of an inspiratory time setting. As appropriate, increase i-time, or PS max i-time, or both.
Decrease expiratory threshold.
High O
2
alarm
The delivered oxygen concentra-
tion is higher than set high limit
Oxygen was increased prior to an
intervention (for example,
suctioning) and was not reduced
back to prescribed value. Adjust oxygen setting back to prescribed value.
Low flow reservoir is in use and:
• Patient’s minute volume has
decreased
• Airway or circuit leak has
decreased during pressure control
and so delivered minute volume is
lower
• NIV is on and bias flow was
decreased
• Oxygen concentrator is putting
out a higher FiO
2
than expected
Evaluate patient and readjust settings or alarm as
appropriate.
High O
2
alarm is set
inappropriately.
Set the High O
2
alarm appropriately.
Oxygen sensor calibration was not
done appropriately. Calibrate oxygen sensor appropriately.
