While in PD mode, low and medium priority alarms mute behavior is maintained. Triggered
low and medium priority alarms will display. When muted or resolved the start menu will
display again. PD mode has no affect on high priority alarms.
The device immediately starts ventilating with the setting described in the table below:
Note:
When the Patient Detect alarm is active the Mode Parameter window displays "---".
The is done to encourage the user to configure the ventilator appropriately for the
patient.
While in PD Mode, Battery and Power, Environmental, and Self check alarms are detected and
displayed when present in the device. Only the following selected patient safety alarm
conditions are detected:
•
Service Code 2110 - Patient Detected
•
Service Code 2062 and Service Code 1060 - Exhalation Valve Fault / Failure
•
Service Code 1061 - Excessive Airway Pressure
Backup Modes
In the event of certain internal system failures, a backup mode takes control to continue
ventilating and alerts the user with audible and visual alarms. While in backup mode the device
continues to ventilate with the currents settings that were in use before the failure. Changes to
the device settings are not possible. The backup mode is activated with all internal COMM
failure alarms. (Service Codes: 1173,1471, 1472, 1474, and 1475)
While in backup mode, if any of the following conditions are detected for three consecutive
breaths, the device will switch to a pressure targeted configuration, see table below, to continue
support of the patient and prevent excessive airway pressure:
•
Airway Pressure High (Service Code: 2070)
•
Patient Disconnect (Service Code: 2100)
•
Auto-PEEP (Service Code: 3091)
Note:
Since the priority of these conditions are lower priority than the initial failure causing
backup mode, these alarms will not be visible in the AMC.
The Mitigation/Resolution Instructions for the individual alarms should be followed to manage
the patient and device if Backup is active.
Apnea Backup Mode
Apnea Backup is activated when the Apnea alarm (Service Code 2076) is triggered during
CPAP or BL mode. The alarm triggers when the spontaneous breathing rate is less than the
BPM low alarm limit. Apnea Backup settings should be configured for the individual patient’s
needs. This is done in the Mode context menu when either CPAP or BL is the mode. Chapter 4
contains detailed information on editing the Mode context menu along with the default settings
and setting ranges.
Additionally, the Manual Breath button delivers a single breath when pressed, using the current
Apnea Backup settings for a mandatory breath in CPAP and BL modes.
