XactTrace and XactTrace Universal are
examples of new sensor technologies developed
at Embla. These respiratory effort sensors
are based on the proven Respiratory Inductive
Plethysmograph (RIP) technology. Both
solutions deliver unmatched effort tracing
accuracy and are comfortable for the patient.
The new XactTrace Universal belt is compatible
with non-Embla systems, as well
as other PSG systems that have the same
signal range.
Why You'll Never Use Anything Else
Superior signal quality
Easy to use and adjust
Adult one size fits all belt reduces
cost and inventory
No additional modules necessary
Cost-Effective
No calibration necessary
XactTrace Technology
XactTrace delivers a highly sensitive
and reliable respiratory effort tracing.
This sensor creates a conductive loop
when stretched around the patient. A precise
quality signal is then generated that
is a measure of the shifts in chest or
abdominal circumference. This technology
is especially accurate in cases of paradoxical
breathing, where an exact and reliable
measure of respiratory effort is needed.
The Embla Software Advantage
In addition to eliminating false paradoxing,
additional derived channels are available
when XactTrace belts are used with Embla's
Rembrandt™and Somnologica™ software
platforms.
XFlow™ - a semi-quantitative
measure of inspiratory and expiratory
flow, provides a complementary flow
signal for studies without airflow
sensors. A reliable backup and great
tool for titrations.
XSum™ - the summation
of the abdominal and thoracic signals
providing a semi-quantitative measurement
of lung volume.
RMI™ - (Respiratory
Mechanics Instability) is a proprietary
algorithm that assesses the severity
of Sleep Disordered Breathing by
analyzing the phase relationship
between the abdomen and thorax.
A Phase Analysis between the thoracic
and abdominal effort and Respiratory Rate
is also provided.
XactTrace vs Piezo
XactTrace measures a cross sectional
area of the torso/abdomen and delivers
a qualitative signal. This gives an accurate
and reliable assumption of the volume
in the lungs.
The polarity of the tracing is always
consistent and the DC characteristics
allow the user to see more clearly the
residual volume in the lungs. The signal
does not drift towards baseline, for example,
if the patient holds their breath.
Piezo crystals measure the tension in
one location where the Velcro bands pull
the sensor during chest/abdominal movement.
The tension gives an indication of the
respiratory movement which corresponds
approximately to the chest/abdominal circumference
but is affected by how the bands pull
the sensor. If the tension is too little,
the polarity of the piezo signal may invert,
which can indicate false paradoxical breathing.
If the patients lie on their side, the
tension can be reduced, as the bands are
not able to pull on the sensor consistently.
Piezo crystals are AC coupled and drift
relatively quickly to baseline. XactTrace
overcomes these limitations.
