In addition to the flashing "VENTILATOR FAILURE" message on the display, the following audible tones that
accompany the alarm may be used to identify which solenoid has failed:

RATE- The monitored rate is calculated and displayed as a rolling average over 5 breaths. In CONSTANT FLOW
mode, the rate alarm is disabled.
HIGH PEAK PRESSURE- Inspiratory is terminated if the peak pressure reaches the set high limit. In Constant
Flow/CMV mode, if a situation arises that causes the Peak Pressure High Alarm limit to be exceeded, PIP and Flow
will be terminated and the unit will alarm. They will be restored when the pressure decreases to what the PEEP
reading was prior to the occurrence. When in Constant Flow/CPAP, this continuously follows the pressure.
LOW PEAK PRESSURE- This alarm is inactive during spontaneous and CPAP breaths
EXHALED TIDAL VOLUME- Exhaled Tidal Volume and Exhaled Minute Volume share the same line in the
ALARM 1 menu. Therefore, only one or the other may be displayed at any given time. To display one or the other,
press either EXHTV or EXHMV, depending on which is currently displayed, and press either arrow key. Repeatedly
pressing an arrow key will toggle between EXHTV and EXHMV. Once the desired parameter is displayed, it becomes
the active alarm.
