9-10 Respironics V200 Ventilator Operator’s Manual REF 1057983 A
Alarms
When a ventilator inoperative condition is detected, the Vent Inop indicator
will display a steady red light, and the ventilator will sound a five-tone audible
alarm sequence.
The Vent Inop alarm cannot be reset by an operator. It cannot be auto-reset or
silenced. The ventilator must be serviced by a qualified service representative,
in order for the Vent Inop audible and visual alarms to be cleared.
Safety Valve
This indicator signals that the Safety Valve is open and the ventilator is not
providing breath support to the patient. It is accompanied by a five-tone
audible alarm sequence and a Safety Valve Open message in the touch screen
display.
The Safety Valve opens automatically whenever the ventilator is not able to
provide breath support to the patient. It allows the patient to spontaneously
breathe room air through the ventilator system.
The Safety Valve Open condition is normal during start-up and restart, and it
automatically turns off when the start-up sequence is complete. If this
condition occurs at any other time, it cannot be reset. Immediately use an
alternative ventilation source and call for service.
Alarm Silence
The indicator ( ) on the Alarm Silence key will illuminate with a steady yellow
light whenever the operator presses the alarm silence control. The indicator
remains lit for two minutes after the Alarm Silence key is pressed. If Alarm
Silence is active and an alarm takes place that involves an operator alarm limit
being exceeded, the alarm will be anunciated visually, but Alarm Silence will
continue to be active and the Alarm Silence timer will continue to time out.
Alarms that can not be silenced are listed in Table 9-1: “Alarm Alert
Messages” on page 9-5. If Alarm Reset is pressed at any time during the Alarm
Silence period, the Alarm Silence period is terminated. If any high or medium
priority alarm condition exists after pressing Alarm Reset, an audible alarm
sounds.
WARNING: When the safety valve open indicator is lit, the ventilator does not provide
any ventilatory support to the patient. Immediately use a backup means of
ventilatory support.
WARNING: Visually monitor the patient and ventilator during the Alarm Silence period
to ensure that alarms do not go undetected. Allowing alarm conditions to
continue without intervention may result in harm to the patient and/or
ventilator.
