General Use Procedure 33
Cuff Deflation
A cuff may be deflated at any time during a procedure.
To deflate a cuff:
♦ Press the Deflate button for the selected cuff for 1.5 seconds.
As the cuff deflates, the following happens:
♦ The numeric pressure and gauge indicate a real-time pressure
decrease. When the cuff pressure reaches zero, the numeric
pressure display and the pressure gauge become blank.
♦ The Deflation indicator appears next to the pressure value on the
relevant side of the display.
In its deflated (inactive) state, the SmartPump continues to monitor ambient
air pressure. The SmartPump exhausts any ambient pressure that may be
caused by cuff or patient movement automatically, prior to cuff removal.
WARNING: At the end of a procedure, as soon as the tourniquet cuff
pressure is released, remove the cuff, sleeve and other underlying
materials. The slightest impedance of venous return may lead to
congestion and pooling of blood in the operative field. Failure to
comply may result in patient injury.
The total elapsed cuff time remains displayed.
Prior to pressing the Default Display button, a deflated cuff may be re-
inflated to the highest pressure used during the procedure by pressing the
Inflate button. The Timer will restart and continue to accumulate inflated
cuff time.
The most recent procedure’s cuff time is cleared when the Default
Display button is pressed.
NOTE: The IVRA Lock may be used to prevent accidental cuff deflation during
Bier Block procedures. See Intravenous Regional Anesthesia (IVRA) Lock
and Bier Block Procedure.
