6.3 Occlusion Pressure
Occlusion pressure is adjustable, which can meet the requirements for occlusion
pressure of different patients during infusion. Pressure in the infusion tube can be
measured by the built-in pressure sensor, pressure can be calculated by the internal
CPU, which is compared with the preset occlusion alarm threshold. [ Occlusion ]
alarm will be triggered if pressure exceeds the threshold.
6.3.1 Set Occlusion Pressure
1. Select [ Main Menu
]→[
General Options
]→[
Pressure ].
2. Select [ Pressure ]: Occlusion pressure Degree 12, lowest at 75mmHg, and
highest at 975mmHg. Occlusion pressure should be selected according to actual
needs.
CAUTION

If the patient experiences discomfort at a higher occlusion pressure,
monitor the patient's physical conditions under the higher occlusion
pressure closely, and take measures instantly if any abnormal condition
occurs.

When the infusion set with ultrafilter at a lower occlusion pressure, the
[Occlusion] alarm might be triggered at high rate due to resistence
generated from liquid flow of ultrafilter. Select a higher occlusion pressure
or lower rate to cancel alarm.
6.3.2 Set Pressure Unit
1. Select [ Main Menu
]→[
User Maintenance
]→Input User Maintenance
Password→[
Pressure Unit ].
2. Select [ Pressure Unit ]: The 4 various forms of pressure units, mmHg, kPa, bar
and psi are converted automatically, and can be selected according to actual
needs.
CAUTION

Carefully confirm the edit when changing the current pressure unit.
