Alarms Unrecoverable errors are displayed on the
EFM LCD by the warning triangle.
Three errors are identifi ed on the ventilator screen
by the alarm message, CHECK TOTAL FLOW. The
three conditions triggering this alarm are:
• Oxygen fl ow is less than 100 ml/min.
• Gas fl ow is absent (indicated on the EFM display
by dashed lines).
• The ventilator receives no fl ow data from the
EFM for more than 45 seconds.
