Detecting circuit disconnection and de-cannulation

Detecting circuit disconnection and de-cannulation
Inadvertent disconnection of a circuit component or accidental removal of a cannula poses a hazard to a
dependent patient. Astral is equipped with a number of alarms that when used in conjunction with the
Disconnection Alarm are able to reliably detect circuit disconnection (including de-cannulation).
The optimal alarm may depend on the therapy target and circuit type as shown in the table below.
However, Astral provides a number of alarms that can be configured by your clinician specifically for this
purpose.
WARNING
Alarm settings are sensitive to any changes to the circuit, ventilation settings or co-therapy. Test
the effectiveness of the alarm after any of these changes are made.
CAUTION
Alarms should be configured and tested to ensure that circuit disconnection and de-cannulation is
detected. We recommend configuring and testing multiple alarms and testing disconnection at the
ventilator and at the cannula. Independent monitoring can be used as an alternative.
The following table provides the most appropriate alarms for use in detecting circuit disconnection.
