XactTrace Effort Belts
XactTrace effort belts 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 any PSG systems.
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
- No calibration necessary
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 RemLogic™ 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.
