Astral Disconnection Alarm
English 123
So if simulating disconnection, the measured disconnection should consistently exceed the
disconnection tolerance (disconnected icon). By contrast, during ventilation of the patient, the measured
disconnection percentage should be mostly below the configured disconnection tolerance.
Some interface types (vented mask and mouthpiece) will allow for the alarm to be turned off.
The default Disconnection Tolerance will change according to the Pediatric/Adult setting and the
Interface type selected. Interfaces offering a very high resistance (eg, small diameter tracheal tubes) may
require a Lower Disconnection Tolerance setting than the default value.
To access the Disconnection Alarm:
1.
Access Clinical mode. The Settings screen is displayed.
2.
Select
. The Alarms screen is displayed.
3.
Select the
Disconnection Alarm
tab.
Note:
The Disconnection Alarm default setting is ON.
To set the Disconnection Tolerance:
These steps should be performed prior to starting ventilation on the patient.
1.
Attach all components of the patient circuit, including interface (a test cannula should be used in the
case of a tracheostomy).
2.
Start ventilation at the appropriate therapy settings, circuit configuration, and supplemental oxygen (if
required).
3.
If necessary, adjust the Disconnection Tolerance value until it is exceeded by the measured
disconnection value which will turn red.
Note:
The Disconnection Tolerance value should not be set above the measured disconnection value otherwise
disconnection or de-cannulation will not be detected.
