GENERAL INFORMATION
• Whenever the Tourniquet cuff pressure is released, the wound should be protected from blood surging back by
applying pressure dressings and, if necessary, elevating the limb. Transient pain upon Tourniquet pressure release
can be lessened by elevation of the limb. If full color does not return within 3 to 4 minutes after release, the limb
should be placed in a position slightly below body level.
• Whenever IVRA (Bier Block anesthesia), is used, it is recommended that the Tourniquet remain infl ated for at least
20 minutes from the time of injection.
WARNING: Cuffs will not defl ate in STANDBY mode. Ensure cuffs are fully defl ated before setting the unit to
STANDBY.
ADVERSE EFFECTS
A dull aching pain (Tourniquet pain) may develop throughout the limb following use.
Pathophysiologic changes due to pressure, hypoxia, hypercarbia, and acidosis of the tissues occur and become
signifi cant after about 1 1/2 hours of Tourniquet use. Symptoms of Tourniquet paralysis are motor paralysis and loss of
sense of touch, pressure, and proprioceptive responses. Intraoperative bleeding may be caused by:
• The slight impeding effect exerted by an unpressurized cuff (and its padding, if used), which prevents venous
return at the beginning of the operation.
• Blood remaining in the limb because of insuffi cient exsanguination.
• Inadequate Tourniquet pressure (between systolic and diastolic blood pressure of the patient), or slow infl ation
and defl ation, all of which allow arterial blood to enter while preventing venous return.
• Blood entering through the nutrient vessels of the long bones, such as the humerus.
SPECIFICATIONS AND PERFORMANCE CHARACTERISTICS
~ AC Power Mains Line Voltage Range 100–240V ~ (AC), 50/60 Hz. Auto switching.
Line Current 1000 mA RMS @ 120V ~ (AC) (max).
Input Power
120 VA
Battery Type Rechargeable, Li-Ion, 14.4 VDC, 4300 mAh.
Battery Discharge Time 360 minutes
Unit will automatically switch and operate on bat-
tery power for 360 minutes minimum with a fully
charged battery when no ~AC Power Mains is de-
tected. Poorly maintained cuffs, hoses, or extreme
pressure transients will impact battery performance.
The backlight will automatically be set to the nomi-
nal value when in backup battery mode.
Battery Recharge Time 10 hours
Unit should be plugged in 10 hours before initial
use. In the event of a deep battery discharge that
cannot be recovered in the fi rst 10 hours, a second
10 hour charging period may be required.
