RTP CALCULATION
LOP

(mmHg)
90–130

131–190

191–300

= 291-400
The RTP can be accepted, overridden, rejected, or changed at the physician’s discretion.
•
When deciding whether to accept the RTP value, the physician may take into account other factors such as the
patient’s blood pressure, anesthetic technique to be used, expected procedure duration, cuff location, cuff type,
cuff width, snugness of cuff application and surgical procedure to be performed.
•
To improve visual quality, the RTP may be overridden at any time by changing the pressure set-point.
The
A.T.S.
4000TS will suggest the RTP for the extremity to ensure the fi eld will remain clear even during changes
in blood pressure. However, large changes in the patient’s blood pressure during surgery may result in reduced
visibility in the fi eld.
LOP PULSE SENSOR
To sense a patient’s pulse, the Zimmer
A.T.S.
4000TS uses a custom LOP sensor applied to the index fi nger or
second toe of the affected extremity. Though it appears very similar to other sensors used for pulse measurements,
the Zimmer LOP pulse sensor is designed for use only with Zimmer
A.T.S.
4000TS tourniquets featuring LOP
technology. The LOP sensor does not measure Oxygen Saturation, nor can it be modifi ed to do so.
CAUTION:
Never use any sensor with the
A.T.S.
4000TS other than approved Zimmer LOP pulse sensors.
Non-Zimmer sensors will not work with the
A.T.S.
4000TS and attempting to use one may damage the
A.T.S.
4000TS or cause unpredictable operation.
CAUTION:
•
The determination of LOP is intended as additional, supplementary information for the physician
responsible for selecting the tourniquet pressure to be employed for a specifi c patient and procedure.
The physician’s judgment should always be paramount in the selection of tourniquet pressure.
•
Certain physiologic or anatomical conditions, including small fi ngers and toes of infants and children,
may prevent the
A.T.S.
4000TS from making a determination of LOP, in which case the instrument
will display an appropriate message and will terminate the attempt to measure LOP. In that event, the
physician’s judgment should be used to set Tourniquet pressure in the absence of the LOP feature.
•
The LOP feature is not intended for use in pediatric procedures.
