Why it occurs
Passive, active flow, or dual limb circuit types:
The estimated exhaled tidal volume is greater than or equal to the High Vte alarm setting for a number
of consecutive breaths. The number depends on the therapy mode as follows.
Three consecutive breaths: A/C-PC, CPAP, PSV, S/T, SIMV-VC, and SIMV-PC.
Six consecutive breaths: A/C-VC
Active PAP circuit type:
The delivered tidal volume is greater than or equal to the High Vti alarm setting for three consecutive
breaths.
What to do
•
Check the patient for pain or anxiety.
•
Check the circuit for kinked or pinched tubing.
•
Ensure that the active exhalation valve is attached.
Note: For active flow and dual limb, low flow O
2
or the use of a nebulizer may increase tidal volumes
beyond the alarm setting.
Device
performance
during active
alarm
The alarm is automatically resolved when a breath occurs in which the exhaled tidal volume does not
reach the High Vte alarm setting.
Device will continue to operate.

Why it occurs
Passive, active flow, or dual limb circuit types:
The estimated exhaled tidal volume is less than or equal to the low tidal volume alarm setting for a
number of consecutive breaths. The number depends on the therapy mode as follows.
Three consecutive breaths: A/C-PC, CPAP, PSV, S/T, SIMV-VC, and SIMV-PC.
Six consecutive breaths: A/C-VC
Active PAP circuit type:
The delivered tidal volume is less than or equal to the low tidal volume setting.
What to do
•
Check the circuit for kinked, pinched, or blocked tubing.
•
Ensure the leak device is not blocked, occluded, or disconnected.
•
Ensure the diaphragm in the active exhalation device is inserted correctly.
•
Check the mask fit or change the mask.
Requirements
Passive, active flow, or dual limb circuit types:
The alarm is automatically resolved when a breath occurs in which the exhaled tidal volume exceeds
the low tidal volume alarm setting.
Device will continue to operate.
