Gas Supplies

The current measured values of the O
adjusted. The inlet pressure for O
If the pressure falls below the limit value, a visible and audible alarm is generated. The operator is
informed about the cause of the alarm by a plain text message on the display. If the adjusted O
concentration is 21% or 100%, only an advisory message (no alarm) is displayed if the non-added gas
type fails.
If the pressure exceeds the limit value, the safety venting mechanism is activated and the continuous flow
is switched off. The Babylog will continue to operate only when the pressure has decreased to a
permissible level.
If the AIR supply fails, the Babylog control switches to O
to AIR supply.

Airway Pressure Monitoring

Depending on the selected mode and parameter settings, a certain airway pressure time profile is set. If
the actual profile deviates from the set profile, the Babylog generates an alarm.
4.4

Disconnect Monitoring

Babylog recognizes whether or not the hose system has been connected correctly. If the hose system has
been connected incorrectly, the continuous flow is (partly) directed to atmosphere. No pressure builds up
in the hose system. Babylog checks during each breathing cycle whether a sufficiently high pressure is
available during inspiration. Since inspiratory breaths occur in the mandatory ventilation modes
IPPV/IMV, SIPPV and SIMV, this monitoring does not function in the CPAP mode.
