Alarms
These messages are accompanied by a repeating intermittent beep of approximately one
second duration. A flashing text message will appear on the screen in area 1, where the
Junior
logo normally sits. Alarms are critical events that have serious implications for the
efficient ventilation or support of the patient. Each alarm that is shown on the screen will
have an asterisk at each end of the text, e.g.:
* OXYGEN SUPPLY PRESSURE LOW *
To clear an alarm manually press and hold any of the 4 control knobs until two beeps are
heard. Here is a list of the alarms.
* OXYGEN SUPPLY PRESSURE LOW *
The piped oxygen pressure, whether it is from the hospital supply Line, or from the E-
cylinders has fallen below 40 psi. This alarm can only be cleared by connecting a source of
oxygen with a pressure greater than 40psi.
* LOW BREATHING SYSTEM PRESSURE *
This Alarm occurs when, at the end of an inspiratory phase during IPPV or Assist, a
maximum pressure of 7 cmH
2
O has not been reached. This can occur when the patient has
become disconnected from the system. It can also occur when the patient takes a breath at
the same time as the ventilator delivers a breath.
The Alarm will continue until either a pressure in excess of 7cm H
2
O is registered during an
inspiratory phase OR the alarm is cleared manually.
* BATTERY 1 CRITICALLY LOW *
and/or
* BATTERY 2 CRITICALLY LOW *
Either one of the batteries voltage has reached the critical level. Below this level ventilator
function may be severely compromised, particularly with regard to piston movement and the
action of the Dump Valve.
The ventilator must be connected to the mains supply
immediately
.
* NO RESPONSE TO INPUT KNOBS *
The circuit board for the front control knobs has failed to respond to the main controller. It
will not be possible to change any of the ventilation settings.
This is a critical error and the
patient should be changed to manual ventilation
.
* RD VACUUM FAILURE *
The vacuum level in the double diaphragm has fallen below a critical level. Continued use of
the ventilator will result in severe damage to the piston assembly. The vacuum level must be
restored before ventilation is re-enabled. Check the connections of the hose at the vacuum
port on the ventilator cylinder
. Until the vacuum has been restored the patient should be
changed to manual ventilation
