Description
3.5 Alarms
User adjustable alarms: Use the menu systems to set the required limits. Press the menu switch on the front panel (see 3.5.2), and select ALARM
SETTING, or touch the alarm area on screen (see 3.5.1)
Alarm Priority Trigger Mute
time
Set by:
Ventilator inoperative (vent
inop) High Internal system failure. Check error log for key zero Automatic
Outlet blocked High Positive pressure on PEEP sensor exceeds 122 cmH2O, due to blocked exhaust
valve outlet zero Automatic
Low supply pressure High Supplied drive gas pressure on pressure switch is less than 235 kPa (35 ±1 psi) zero Automatic
Low airway pressure High Bellows drive gas pressure sensor fails to see at least 75% of set target level
(pressure control) 120 s Automatic
Low drive gas pressure High Airway and drive gas pressure fails to reach minimum level (volume control) 30 s Automatic
High drive gas pressure High Airway and drive gas pressure exceeds calculated target level 120 s Automatic
High continuous pressure High PEEP +10 cmH2O for 1 cycle, or PEEP +5 cmH2O for 3 cycles. A PEEP value
of 4 cmH2O is used for PEEP values ≤4. Standby: the alarm triggers after 15
seconds
120 s Automatic
High airway pressure High Airway pressure sensor: Pressure reaches set limit (10 to 80 cmH2O adjustable) 30 s User/Default
Negative airway pressure High Airway pressure sensor: Breathing system pressure exceeds (-)10 cmH2O 120 s Automatic
Check pressure sensing High Airway pressure sensor: Breathing system pressure exceeds (-)10 cmH2O 120 s Automatic
Low tidal volume (V
T
) High a) Expiratory spirometer sensor: Measured V
T
less than 50% of volume set
b) Expiratory spirometer sensor: disconnected
120 s User/Default
Low minute volume (V
M
) High Expiratory spirometer sensor: Calculated volume lower than -50% of volume
set 120 s User/Default
Apnoea High Breath not detected within 15 seconds in spontaneous mode. 15-120 s Automatic
High tidal volume (V
T
) High Inspiratory spirometer sensor - measured value exceeds 150% of set value 120 s User/Default
High minute volume (V
M
) High Inspiratory spirometer sensor - calculated value exceeds 150% of set value 120 s User/Default
High O2 concentration % High Oxygen monitor : Measured O2 % exceeds set value 120 s User/Default
Low O2 concentration % High Oxygen monitor: Measured O2 % lower than set value 120 s User/Default
O2 sensor low output Low Oxygen monitor: Output voltage low, sensor life exhausted / sensor not
calibrated zero Automatic
Oxygen sensor fault High Oxygen monitor sensor disconnected 120 s Automatic
Rate or ratio error Medium Ventilator parameter settings unachievable 120 s Automatic
AC power failure Low Mains power fails. Note: A fully charged battery gives 60 minutes use. zero Automatic
Battery power fail Medium Ventilator is running on mains power, but: (a) Battery is disconnected or not
fitted. (b) Battery is discharged below critical level 120 s Automatic
Low battery Low Ventilator is running on mains power or battery power, but battery charge is
approaching a critical level. Note that if the ventilator is running on battery
power, less than 20 minutes battery life remains. zero Automatic
Power about to fail High Ventilator is running on battery power and is about to shut down because
battery power is depleted to a critical level. Note: (a) Less than 5 minutes
battery life remains. (b) When total power failure is imminent, the shutdown
procedure starts automatically. zero Automatic
Cable fault Low Disconnection or short circuit zero Automatic
Primary alarm fault Low Primary alarm circuit not functioning.
Note that incidence of this alarm is
accompanied by a continuous tone from the secondary alarm system while any other
alarm condition is in effect.
zero Automatic
Printer not available Low Printer disconnected, or has no power, or has no paper. zero Automatic
Priority level:
1. High priority: Five ascending tones - repeated.
2. Medium priority: Three ascending tones - repeated.
3. Low priority: Single tone
