Universal–Single Use XactTrace™
Instructions
The Universal-Single Use XactTrace Respiratory Inductive Plethysmogragh
(RIP) sensor belt is a respiratory effort sensor used in the diagnosis of
sleep disordered breathing. XactTrace measures changes in inductance,
and converts it into a digital signal that gives both qualitative and
quantitative data. This sensor is more sensitive and reliable than typical
respiratory effort sensors, especially in cases of paradoxical breathing.
The Universal-Single Use XactTrace belts consist of a belt roll that can be
cut to appropriate lengths for each patient and two Belt Locks for the
abdomen and thoracic regions.
Fitting the XactTrace Belts
The XactTrace belts must be custom fit for each patient. When using the
XactTrace belts, avoid all unnecessary contact with
moisture.
1. Encircle the belt around the patient’s chest
under the arm to approximate the
circumference for the thoracic belt.
2. When cutting the belt, reduce its circumference by 10-15cm (4-6
in) so it stretches around the thorax. The belt should fit snugly to

prevent slippage during the study. It is important to use sharp
scissors for a clean cut.
The wire should not exceed the end of the belt.
3. Secure the cut ends of the belt into the Belt Lock with the blue
connector according to the following steps:
Twist the top end of the
Belt Lock clockwise to
open the catch. The white
mark on the top should
match the open lock
symbol on the catch.
Insert the cut end
of the belt into
the catch. Make
sure to insert the
end all the way
to the bottom of
the catch.
Twist the top end of the
Belt Lock counter-
clockwise to close the
catch. When the white
mark on the top
matches the closed lock
symbol on the catch, the
Belt Lock is properly
closed.
4. Prepare the abdominal belt in the same manner, only this time, fit
the belt around the patient’s stomach at the navel, and use the
Belt Lock with the yellow connector.
Attaching the XactTrace Belts
The XactTrace belts are intended to be worn over the patient’s
nightclothes.
1. Place the belt with the yellow connector around the patient’s
stomach, at the navel.

2. Take the two components of the Belt Lock and connect them, as
shown below.
3. Place the second belt with the blue connector around the patient’s
chest, under the arm.
4. Connect the second Belt Lock as shown above.
5. Insert the connector from the Chest belt into the driver module
labeled Thorax (* in the following drawing).
6. Insert the connector from the Abdomen belt into the driver module
labeled Abdomen.
7. Plug the thorax module output into the appropriate bipolar input
of your polygraph. The red touch-proof plugs into (+) input, and
the black plugs into (-) input.
8. Plug the thorax module output into the appropriate bipolar input
of your polygraph.

Note: Do not use two abdomen or two thorax modules in the
same recording. This causes interference between the two
sensors, resulting in bad signals.
Storage
Proper storage of the XactTrace Belt Locks between recordings is
important.
To protect the sensor cable from damage, do not wrap it tightly around
the Belt Lock, as it might cause the cable to break where it connects to the
Lock.
Do not wrap the wires around the Belt Locks, as it may cause the
wire
to break.
To save battery power, the modules MUST be disconnected from
the Belt Locks when not in use.

Cleaning and Disposal
Wipe the Driver Modules and Belt Locks clean with a moist cloth in
hospital-grade laundry detergent, then dry them with a clean, dry cloth.
Take care to avoid contact of the cleaning solution with the sensor
connector and plug of the Belt Lock. The Belt Lock does not require
sterilization.

The belts do not need cleaning, as they should be discarded after use.
Warnings
See the list of warnings below.
Do not stretch the belts too tightly around the patient, as this may
cause discomfort. To prevent the belt from slipping during the
study, fix the position with medical tape.
The belts shall be worn over night clothes.
This product is for diagnostic purposes only, and is not to be used
as an apnea monitor.
Take care not to cut any cables when cutting the belts.
Do not use damaged sensors or accessories.
Be certain that cables or sensors do not encircle the patient’s
neck.
Do not use the equipment in a magnetic resonance imaging
(MRI) environment.
Do not use the device in an explosive environment—in other
words, in the presence of flammable liquids, such as aesthetic
mixture with air, or with oxygen or nitrous oxide.
Connect the XactTrace sensors to an electrically isolated input
only. Do not plug the cables into electrical outlets, as this could
result in serious electrical shock.
The device contains a battery; therefore, it must be disposed of
properly. Local, state, or national laws might prohibit disposal of
batteries in ordinary trash. Contact your local waste authority for
information regarding available recycling and disposable
options.
Portable and mobile radio frequency (RF) communications can
affect the performance of the device.
