LTV 1100 Operator Manual - CareFusion

HIGH f
When the Total Breath Rate (f) exceeds the high breath rate and time period alarm values, the HIGH
f alarm is generated.
To prevent nuisance alarms, the HIGH f alarm is suspended for the first 60 seconds of ventilator
operation after power up and passing the Power On Self Tests.
When a HIGH f alarm occurs:
The HIGH f message is flashed in the display window.
The audible alarm is sounded.
To reset the HIGH f alarm:
1) Push the Silence Reset button once to silence the audible alarm.
2) Push the Silence Reset button twice to reset the alarm (silences the audible alarm and clears the
flashing display).
When the HIGH f alarm is reset (Silence Reset button pushed twice), the alarm is
suspended for the next 60 seconds.
The 60-second suspension of the HIGH f alarm is only enabled when the alarm is manually
silenced/reset by pushing the Silence Reset button twice. It is not enabled when the HIGH f
alarm is automatically silenced/reset because the patient’s breath rate no longer exceeds the
set HIGH f alarm value.
