Once either the flow target or the maximum pressure is reached, the ventilator
automatically terminates FLC if:
• negative flow is detected, or
• flow varies from the current flow by over 40 LPM (software versions
earlier than 13.2) or 20 LPM (software versions 13.2 and later).
Example: if 160-170 LPM is reached, the ventilator terminates FLC if:
• flow is below 120 LPM or above 210 LPM (older software)
• flow is below 140 LPM or above 190 LPM (newer software)
If the flow target is not reached, the ventilator targets the maximum pressure
instead (10 cmH O for software version 11.2 and 11.3, or 15 cmH
2
software version 11.3a and higher).
Example: if the ventilator can only reach 80 LPM at 10 cmH
software) or 15 cmH O (newer software), FLC terminates if of
2
• flow is below 40 LPM or above 120 LPM (older software)
• flow is below 60 LPM or above 100 LPM (newer software)
This allows FLC to terminate when the mask is refitted to the patient, without
requiring the patient to breathe back into the ventilator.
To terminate Standby manually (which is also terminated automatically as
described above), methods, select the highlighted Standby soft key on the
Monitoring screen.
When FLC is terminated during a Disconnect alarm, the alarm self-cancels
(that is, the audible alarm is silenced but the visual alarm remains). To clear
the alarm, press the Alarm reset key.
NOTE: During FLC oxygen concentration is 21%, regardless of the setting.
