High-priority alarm.<br />
Two consecutive breaths were<br />
truncated because circuit<br />
pressure reached the HIGH<br />
PRESSURE setting. (Inspiration<br />
phase ends and exhalation<br />
valve opens to prevent<br />
excessive pressure.)<br />
Autoreset when circuit pressure<br />
is less than alarm setting for<br />
5 breaths. Cannot be silenced if<br />
alarm condition persists.<br />
Medium-priority alarm.<br />
Delivered tidal volume less than<br />
LOW TIDAL VOLUME setting for 3<br />
out <strong>of</strong> 4 consecutive breaths. If<br />
LOW TIDAL VOLUME ALARM<br />
setting = 0 and breath type is<br />
PCV, this alarm indicates that<br />
delivered tidal volume is less than<br />
3 ml for 3 out <strong>of</strong> 4 consecutive<br />
breaths.<br />
Autoreset when delivered value<br />
is at least equal to alarm setting<br />
for 3 out <strong>of</strong> 4 consecutive<br />
breaths.<br />
Alarm handling<br />
Check patient.<br />
Check for water in the<br />
inspiratory limb or<br />
kinked tubing.<br />
Consider appropriate<br />
HIGH PRESSURE and<br />
ventilator settings.<br />
Check patient. Check<br />
for blocked or kinked<br />
ET tube (PCV and PSV<br />
breath types when<br />
LOW TIDAL VOLUME<br />
setting = 0).<br />
Consider appropriate<br />
