Vivosonic Integrity

Vivosonic Integrity™

Using Kalman Weighted Filtering, the Integrity is able to generate superior diagnostic results without sedation. This is particularly suitable to pediatric patients, who can now feed, speak, play or wake up while being tested. It is also an invaluable tool for-hard-to test patients from the general population.

​The first system to possess wireless capabilities, Integrity is a revolution in portable diagnostics, fitting unobtrusively on an alert child’s back who is playing quietly during testing, or into the OR. In addition, the Amplitrode (a miniature electrode mounted bio-amplifier) protects against electromagnetic noise, delivering clear results in places with electric and magnetic interferences such as Neonatal Intensive Care Units (NICU), hospitals, military medical centers, Operating Rooms (OR) and other clinical settings
