Alarms
This ventilator contains several alarms: high airway pressure, low source gas, low
battery, and breath delivery failure.
The high airway pressure alarm is an audible alarm with a red LED that is actuated
when the airway pressure during inspiration reaches 45 cm H
relief will actuate at pressures between the alarm setting and 60 cm H
Warning: Preset tidal volumes may not be delivered when the
maximum pressure limit is reached. Inspiratory times will remain
constant. However, no additional tidal volume will be delivered after
the pressure limit is reached.
This alarm is automatically cleared when 25 seconds pass without a high airway
pressure being detected.
The low source gas alarm is an audible alarm with a red LED that activates when the
source gas pressure drops below 40 to 35 psi. This is an indication that the unit will
stop functioning soon and that the unit may not be delivering proper tidal volumes.
Warning: Preset tidal volumes may not be delivered when the low
source gas pressure is reached.
This alarm clears when proper source gas pressure is restored for 15 seconds.
The low battery alarm is a red LED that indicates the battery is running low. The unit
will operate for approximately 2 hours after the alarm first turns on. The batteries
should be replaced when the low battery alarm turns on.
Warning: The displays on the unit will stay on after the unit has
stopped delivering breaths. Batteries should be replaced when a low
battery condition is encountered.
This alarm clears when the batteries have proper battery voltage.
The breath delivery alarm is a flashing red LED. This alarm uses the same light as the
high airway pressure alarm. The breath delivery failure alarm will sound when the
airway pressure does not reach 9 cm H
is detected. This alarm may indicate that the patient has become disconnected from the
unit or the unit has stopped delivering breaths. This alarm clears when airway pressure
exceeds 9 cm H

Silence Button – When an alarm occurs, the user may press the button for the
currently selected inspiratory time for 3 seconds to silence the alarm. This will turn off
the buzzer for 110 seconds as long as there are no other alarms. Pressing this button
will not clear the alarm LEDs.
