7.2 Alarm silence<br />

7-00086<br />

7-00423<br />

Alarm handling<br />

Silences the alarm sound for 2 minutes<br />

from the most recent key press. (The visual<br />

alarm indicators do not change.) If a new<br />

alarm occurs during the alarm silence<br />

period, the alarm sound resumes. If the<br />

condition that caused the initial alarm still<br />

exists after 2 minutes, the alarm sound<br />

resumes.<br />

NOTE:<br />

If the condition that caused a HIGH PRESSURE alarm persists, it<br />

cannot be silenced.<br />

During certain bedside procedures, you may want to silence new<br />

alarms. Pressing the alarm silence key when the ventilator is in a<br />

normal state prevents a new alarm from sounding for 2 minutes. If a<br />

new alarm occurs, the ALARM or CAUTION indicator flashes and its<br />

alarm message is displayed in the message window. New alarms that<br />

do not sound if an alarm silence is in effect are:<br />

• APNEA<br />

• DISCONNECT<br />

• HI EX TIDAL VOLUME<br />

• HI RESP RATE<br />

• HIGH PRESSURE (if circuit pressure is less than 90 cmH2O (90 hPa)<br />

• LO EX TIDAL VOLUME<br />

• LOW EX MINUTE VOLUME<br />

• LOW INSP PRESSURE<br />

• LOW RATE<br />

Warning<br />

For all bedside procedures, such as breathing circuit disconnection,<br />

<strong>Covidien</strong> recommends that you use the alarm silence key only<br />

when you plan to perform the procedure immediately.<br />
