INSTALLATION AND OPERATING INSTRUCTIONS
CAUTION:
•
An LOP measurement is used only to obtain patient LOP prior to Tourniquet use, but is not necessary
before using the
A.T.S.
4000TS.
•
Once the patient LOP measurement is complete, remove the LOP sensor from the patient and store.
DUAL-BLADDER CUFF LOP MEASUREMENT
LOP measurement for a dual bladder cuff is identical to a single bladder cuff except for the following points:
1
Connect a dual bladder dual port cuff to the unit (Reminder: Main Cuff is the Red ports, Second Cuff is the Blue
ports).
2
At the end of the LOP determination using the fi rst bladder, touch the Next button
to accept the RTP as the
set-point as well as any additional adjustments made. Touch the Cancel button to reject the RTP.
3
Begin an LOP determination using the second bladder by pressing its corresponding LOP button
.
4
At the end of the LOP determination using the second bladder, touch the Next button
to accept the RTP as
the set-point as well as any additional adjustments made. Touch the Cancel button to reject the RTP.
5
Compare the RTP currently displayed with the RTP that was accepted in step 2 above.
CAUTION:
•
The RTP accepted in step 2 above is now the pressure set-point for that cuff. To verify the RTP,
momentarily press the corresponding PRESSURE button. During this activity the RTP in step 4 will
temporarily be “cleared” from the display but will return following a 3-second delay.
•
If the RTP from the fi rst LOP determination is higher than the second RTP, adjust the pressure setting to
the higher RTP. Refer to Manual Tests and Checks for how to adjust pressure.
•
If the RTP from the fi rst LOP determination is lower than the second RTP, adjust the pressure in the fi rst
RTP to the higher RTP of the second determination. Refer to Manual Tests and Checks for how to adjust
pressure.
CUFF OPERATION
This section describes operation of the
A.T.S.
4000TS Tourniquet Cuff functionality. See below for details of:
•
Single Cuff Operation,
•
Dual Cuff Operation
, and
•
Bier Block (IVRA) Cuff Operation
.
SINGLE CUFF OPERATION
1
Press the
button to turn the unit ON.
The unit will execute a diagnostic and calibration self-check test. After successful completion of the self-check test, the
A.T.S.
4000TS unit is ready for use. The default settings for cuff pressure and time limit are retrieved during power-up.
CAUTION:
If a connected cuff is pressurized to 50 mmHg or more during power-up, the
A.T.S.
4000TS
Tourniquet will declare it an abnormal start-up sequence. It will assume that a surgical procedure is in
process, and will adopt the pressure sensed in the cuff as the new set-point. It will automatically go into
the regulate mode on the cuff. To alert the operator of this condition, the unit will sound a tone and display
a “CUFF INFLATED” alarm. The operator should immediately check the pressure set-point by touching the
corresponding pressure tile and readjust to the proper set-point if necessary. The alarm will be cleared as
soon as the cuff set-point is examined.
