TVe Below
Control Range
M In the VCV mode, TVe is lower than the minimum tidal
volume setting for five continuous breathing cycles. Check
the patient’s condition, pneumatic circuit connection and
flow sensor.
MV Too High M MV is higher than the high alarm limit setting. If ventilation
mode is switched or settings for ventilator parameters are
changed, this alarm is disabled temporarily within nine
breathing cycles or one minute (whichever is less) after
being set. Decrease settings for tidal volume or breath rate,
or increase high alarm limit.
MV Too Low M MV is lower than the low alarm limit setting. If ventilation
mode is switched or settings for ventilator parameters are
changed, this alarm is disabled temporarily within nine
breathing cycles or one minute (whichever is less) after
being set. Increase settings for tidal volume or breath rate, or
decrease low alarm limit.
Apnea Alarm M Two triggering conditions are met simultaneously:
1. Paw is lower than (PEEP+3) cmH
2
O for more than 20
seconds.
2. TVe is lower than 10 ml for more than 20 seconds.
Increase tidal volume and breath rate settings, or apply
manual ventilation.
Vo l u m e
Apnea>2 min
H No breath has been detected within the last 120 seconds.
Check the patient’s condition. Use manual ventilation mode
to help the patient breathe. Check if the tubes fall off.
Rate Too High L Rate is higher than the high alarm limit setting. If ventilation
mode is switched or settings for ventilator parameters are
changed, this alarm is disabled temporarily within nine
breathing cycles or one minute (whichever is less) after
being set. Decrease breath rate setting or increase high alarm
limit.
Rate Too Low L Rate is lower than the low alarm limit setting. If ventilation
mode is switched or settings for ventilator parameters are
changed, this alarm is disabled temporarily within nine
breathing cycles or one minute (whichever is less) after
being set. Increase breath rate setting or decrease low alarm
limit.
Pressure
Limiting
L Paw is greater than Plimit. Increase Plimit or decrease TV or
Rate.
