6.3.3 Dynamic Pressure Scanning (DPS)
During the infusion, the bottom-right corner of the Run screen demonstrates real-time
pressure changes of the patient, in order to find the tube occlusion at an earlier time
and to prevent the occurrence of further complications.
The pressure icon on the screen indicates the condition of the current pressure:
◆
When the progress bar is white, this indicates that the current pressure
value is below 80% of the occlusion pressure.
◆
When the progress bar is yellow, this indicates that the current pressure
value is above 80% and below 95% of the occlusion pressure.
◆
When the progress bar is red, this indicates that the current pressure
value is above 95% and below 100% of the occlusion pressure.
NOTE

When occlusion occures in the infusion set before entering the device, or
occlusion pressure reaches the threshold value. The occlusion alarm will
sound, and the screen will display “Upstream occlusion”.

When occlusion occures in the infusion set between the device and the
patient, or occlusion pressure reaches the threshold value. The occlusion
alarm will sound, and the screen will display “Downstream occlusion”.
6.3.4 Automatic Pressure Release Function (Anti-Bolus)
When occlusion occurs, infusion will stop and the [ Downstream occlusion ] alarm
will be triggered. After the alarm is triggered, the motor is reversed, and the cannula
pressure is then released. This prevents an additional aggressive dose to the patient
after the occlusion is eliminated.
6.4 Set Air Detection
Air bubble size indicates the size of air bubble that can be monitored in the tube. The
lower of the bubble size, the smaller air bubble can be identified. Bubble in the
infusion tube can be measured by the built-in ultrasonic sensor, bubble size can be
calculated by the internal CPU, which is compared with the preset threshold. [ Air in
line ] alarm will be triggered if bubble size exceeds the threshold.
1. Select [ Main Menu

Air detection ].
2. Select [ Air detection
], 6 levels of air detection can be selected, lowest at 20μl,
and highest at 800μl. Air detection level should be selected according to actual
needs.
