Non-invasive blood pressure (NIBP)
Venous stasis
By maintaining a constant cuff pressure, the M540
stops the blood flow to the lower extremity of the
cuffed limb long enough to cannulate a patient. In
this mode, the cuff occludes the limb for about as
long as an non-invasive blood pressure
measurement takes (approximately 2 minutes for
adults and approximately 1 minute for neonates).
Activating or deactivating venous stasis
To activate or deactivate venous stasis
1 Select the non-invasive blood pressure
parameter field to select the NIBP page directly,
or
Select Sensor parameters... from the main
menu bar.
2 Select the NIBP tab to access the NIBP page.
3 Make sure non-invasive blood pressure
continuous mode is not activated (see
page 300).
4 Select On next to Venous stasis.
During active venous stasis, the non-invasive blood
pressure parameter field reports the remaining time
and displays the message Stasis in the parameter
field. As soon as venous stasis is terminated, the
parameter field resumes its previous appearance
(see page 294).
Interval measurements are suspended during
venous stasis but resume immediately after the cuff
deflates.
WARNING
Do not use venous stasis on a limb that is
unsuitable for non-invasive blood pressure
measurements (for example, an arm with a
catheter). If the patient experiences adverse
reactions, immediately press the NIBP
start/stop button to deflate the cuff.
NOTE
Make sure continuous non-invasive blood pres-
sure mode is not enabled (see page 300) be-
cause it prevents you from using venous-stasis
mode.
NOTE
If configured to appear on the main menu bar, the
Venous stasis button is also accessible on the
main menu bar. For more information, see
page 452.
NOTE
When the venous-stasis mode begins, an
attention tone sounds.
