Alarms
Many alarms such as HIGH PRES or LOW O2 PRES can occur during normal operation. Information
on addressing alarms is covered in Chapter 9 – Ventilator Alarms. Single occurrences of some
alarms, such as HW FAULT or RESET may be caused by ESD. If these alarms reoccur, and for other
alarms that do not usually occur during normal operation, follow the instructions in this section or
immediately contact Pulmonetic Systems.
Multiple Alarm Priorities
When multiple active alarms occur at the same time, the alarm with the highest priority level will be
displayed. When a highest priority active alarm is reset, any remaining active alarms will be displayed
in order of priority one by one as each alarm is reset.
When multiple alarms occur:
• A flashing alarm message appears in the display window showing the highest priority active
alarm.
• An audible alarm will sound.
• Any associated control displays will flash.
• Depending on the alarm, other actions may be taken, such as terminating an inspiration or
opening the exhalation valve.
When an alarm is reset and other alarms have occurred at the same time, the active alarms will occur
in order of priority level until each alarm is individually reset.
Active alarms take priority over inactive alarms.
Priority levels
Alarm condition priority levels are categorized in one or more of the following levels: High Priority,
Medium Priority, or Low Priority.
