Automatic Alarms
The following alarms are automatically set by the ventilator based on patient settings or device
condition. Violated alarms are indicated by an audible alarm, an alarm message displayed on the
touch screen, and the LEDs in the handle flashing.
+ only available on the HT70PM when the on-airway flow sensor is in use
6.5.1
High Baseline Pressure Alarm
The High Baseline Pressure alarm is activated by obstruction or high resistance to exhalation.
Check for obstructions to patient exhalation or for improper exhalation valve function. This could
be caused by aerosol medication buildup on the exhalation valve, an occluded filter, or incom-
plete exhalation due to auto-triggering.
6.5.2
Low Baseline Pressure Alarm
The Low Baseline Pressure alarm is activated by an unstable baseline (for example, leak in the
breathing circuit or at the patient interface). Check for leaks and for improper exhalation valve
operation. If the leak is purposeful (that is, deflated tube cuff), turn NIV on and adjust bias flow to
stabilize PEEP (baseline).
