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.

The inflation limits, venous stasis pressure and venous stasis times are listed in the table below.
Inflation limit
Infant 150+5 mmHg (19.3 ± 0.7 kPa)
Child 200+10mmHg (26.7 ± 1.3 kPa)
Adult 280+10 mmHg (37.3 ± 1.3 kPa)
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)
