B30 Patient Monitor
16-8
Using venous stasis
Venous Stasis initiates and holds the pressure in the cuff to help venous cannulation. A
constant pressure is maintained in the cuff. The value is selected automatically after the
inflation limits (infant, child or adult) are set.
To release the pressure before two minutes have expired:
•
Press the
Start/Cancel
key on the module, or
press the
NIBP
key on the Command Board and select Stop Ven. Stasis .
The inflation limits, venous stasis pressure and venous stasis times are listed in the table below.
Venous stasis pressure may be lower than the values above if the patient has low blood
pressure. The venous stasis pressure adapts to the measured mean pressure being
approximately the same as the mean pressure but always at least the following:
Infant 20 ± 5 mmHg
(2.7 ±0.7 kPa)
Child 30 ± 5 mmHg (4.0 ±0.7 kPa)
Adult 40 ± 5 mmHg (5.3 ±0.7 kPa)
Inflation limit Maximum venous stasis
inflation limit Venous stasis time
Infant 150+5 mmHg (19.3 ± 0.7 kPa) 40+5mmHg (5.3 ± 0.7 kPa) 1 min
Child 200+10mmHg (26.7 ± 1.3 kPa) 60+5mmHg (8.0 ± 0.7 kPa) 2 min
Adult 280+10 mmHg (37.3 ± 1.3 kPa) 80+5 mmHg (10.7 ± 0.7 kPa) 2 min
