mmHg). The default value can be adjusted in the settings (3.1.6)

Accurancy of the pressure

The Hpm™ Tourniquet is designed in order to maintain the inflated cuff pressure during the
time of the procedure.
When the cuff is inflated, you may change the Pset pressure in steps of + or – 5 mmHg keys, or
press the "Pset" icon and use the menu (section 3.2). A change of the Pset pressure will result in
a change in the inflated cuff(s).
If an unexpected change of the pressure is detected, an alarm message is shown, followed of an
audio alarm. Reset the alarm by pressing the "Alarm" button and locate the cause of the alarm
and take corrective measures (ref. chap. 4) .

Inflate/deflate cuff in normal mode

In order to inflate the cuff, press the "Inflate" icon. The pressure will be achieved within
seconds, meanwhile a leak test is performed. If no leaks are detected, the pump will inflate the
cuff until the desired pressure is achieved. A white frame and a green arrow indicate which cuff is
inflated and active. If a leak or a kink is detected during the inflation, the pump tries to inflate the
cuff. If inflation fails, the user will be alerted by an error message followed by an audio alarm (ref.
chap. 4). Inflation can be aborted at any time by pressing "Deflate". If you press "Deflate", you
will have to confirm the deflation, by answering the question " Deflate the distal/proximal
cuff?", by pressing "Confirm". This will deflate the cuff in approximately 15 seconds.

Timer

A timer is built into the tourniquet. The timer is activated automatically each time a cuff is
inflated. The time is noted on the display along with the cuff pressure. The time is shown on the
display as YYY min (minutes). The timer counts each minute that the pressure is retained in the
cuff(s). A beep alerts the operator after sixty (60) minutes, after an additional period of thirty
minutes another beep alerts the operator of the time elapsed. After the thirty (30) minute beep,
the operator will be alerted by a beep every fifteenth (15
After one hundred and eighty (180) minutes the alarm goes into medium priority level which
means three (3) beeps repeated every twenty (20) seconds
the cuff(s) is deflated. The total of the elapsed time that the cuff has been inflated will be shown
on the display until a new procedure starts. When performing an IVRA procedure, the time
shown is the total time which the proximal and the distal cuffs have been inflated. Each side has
an individual timer.
The timer has the "Counting Up" or "Counting Down" options. In order to change time
counting, enter the sub menu (section 3.1), timer (section 3.1.2) to make changes.
Factory default setting (090 minutes) can be restored by entering sub menu (section 3.1), press
the "Settings" icon and press "Restore default" (section 3.1.6)
