Alarms
Power Fail
If the electrical power to the ventilator is interrupted, an audible
alarm will sound. This alarm will run for 5 minutes unless cancelled with the mute
button. Once cancelled the power fail alarm will not re-activate.
Low Internal Battery
When running on its internal battery, the alarm will operate when
the battery is low. This could last for up to 1 hour. When the alarm becomes constant
there is approximately 10 minutes running time left.
Low External Battery
When running on its external battery, the alarm will operate
when the battery is low. This could last for up to 1 hour. When the alarm becomes
constant there is approximately 10 minutes running time left.
Low Pressure
A pre-set low pressure alarm is provided. If the control pressure falls
to below 50% of the set IPAP level for 10 seconds an audible and visual alarm will
operate.
High Pressure
A pre-set high-pressure alarm is provided. If the pressure rises above
120% of the working pressure, an audible and visual alarm will operate after a 2 second
delay.
Breathing Circuit Disconnect
A disconnection alarm is provided as a back up to
the high flow alarm. If the patients flow waveform indicates that a significant leak
maybe present in the breathing circuit an audible and visual alarm will operate.
The sensitivity of the alarm is adjustable
.
Breathing Circuit Malfunction
This alarm warns of a malfunction of the exhale
valve in the IPPV mode circuit.
High Flow alarm
An adjustable alarm is provided to warn of excess inspiratory flow.
This is activated when the inspiratory flow exceeds the set high flow alarm level
for 5 seconds. An audible and visual alarm will operate.
Low Flow alarm
An adjustable alarm is provided to warn of insufficient inspiratory
flow. This is activated when the inspiratory flow fails to achieve the set low flow
alarm level for 10 seconds. An audible and visual alarm will operate.
Apnoea Alarm
An adjustable Apnoea alarm is provided. If an apnoea is detected an
audible alarm will sound with a visual indication on screen.
Max Breath Rate
An adjustable maximum breath rate alarm is provided. If the max
breath rate is exceeded an audible and visual alarm will operate.
Fault
The alarm may also be operated by an internal fault. In this case the fault will be
displayed on screen.
These alarms may be muted for approximately 2 minutes to allow for setting up of
the ventilator.
Low Internal Alarm/Memory Battery
An intermittent alarm (short beep) with no
onscreen message indicates a depleted mains fail alarm battery. If the ventilator has
been stored for more than a few weeks the internal battery will self-discharge. In this
case the alarm will stop after the battery has recharged.
