5 Ventilator settings
5.7.1 Limits: Setting alarm limits
WARNING
• Ensure the alarm limits are appropriately set
before you place the patient on the device pre-
venting possible patient injury.
• Although you can set all alarms rapidly using
the
Auto
alarm function, some settings are not
appropriate under all clinical conditions. HAM-
ILTON MEDICAL recommends: you set the
alarms manually when possible. If circum-
stances require to use the
Auto
alarm function,
verify the correctness of the settings at the
earliest opportunity.
NOTE:
• Always ensure the high pressure alarm is correctly
set. This alarm provides a safety pressure limit for the
device to appropriately adjust the inspiratory pres-
sure necessary to achieve the target tidal volume.
The maximum available inspiratory pressure for
INTELLiVENT
®
-ASV, ASV
®
, APVcmv and APVsimv is
10 cmH2O below the high pressure limit, indicated
by a blue colored band on the pressure waveform
display. Set the high pressure limit to a safe value
(example, 45 cmH2O, this limits the pressure target
to a maximum of 35 cmH2O). When the high pres-
sure alarm is set too low, it can lack enough margin
for the device to adjust its inspiratory pressure to
deliver the target tidal volume.
• In the ASV
®
and the INTELLiVENT
®
-ASV controls
window, the high pressure alarm will be changed by
adjusting the Pasv limit (pressure target 10 cmH2O
below high pressure alarm limit).
