Alarms
Low External Battery When running on an external battery, the alarm will operate
when the battery is almost depleted. Machines fitted with an internal battery will
automatically switch to internal battery power without alarming.
High Pressure A pre-set high-pressure alarm is provided. If the pressure rises above
120% of the working pressure, a visual alarm will operate after a 2 second delay.
Patient Pressure Tube Disconnected If the pressure pick up tube is not
connected the clearway will use the internally measured pressure for control. A
visual alarm will operate after a 2 second delay. This does not compensate for the
length of the circuit. Reconnect the pressure tube for most effective treatment.
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 cancelled by pressing the Set button.
Low Internal Alarm/Memory Battery If the machine has been stored for more
than a few months, the internal memory back up battery will self discharge. An
intermittent alarm (short beep) with no onscreen message indicates a depleted
memory back up battery. The alarm will stop after the battery has started to
recharge. This may take a few minutes.
The user cannot replace this battery. Refer to qualified technical personnel if
the alarm operates when the Nippy Clearway is in daily use.
Inspiratory Trigger
The Nippy Clearway employs a unique triggering mechanism. When the patient
starts to inhale, the decrease in pressure and increase in flow rate causes the
internal control valve to move
as an automatic response in order to compensate for
the pressure drop. This movement signals the start of inspiration.
