Finapres - Guided Automatic Testing Software
New GAT application enables standardization and quantification! In autonomic testing, standardized procedures are essential for reliable test results. Finapres Medical Systems developed a Guided Autonomic Testing (GAT) application as part of the Finapres® NOVA, which guides the operator and the patient through a series of autonomic test maneuvers.

Software Overview
The GAT application consists of a graphical user interface on the NOVA and also includes a tablet. The tablet provides instructions for the patient during the tests and has the ability to record a video during the test. Upon completion of the test, the application generates a PDF report with quantified results of all performed tests. Together, all these features support standardization and quantification of your autonomic tests!
- Valsalva test
- Tilt Table test
- Deep Breathing test
- Stand test
- Cold Pressor test
- Carotid Sinus Massage test
- Drugs Administration test
The GAT application uses a pre-defined protocol. Yet, all test protocols are adjustable. This means that the operator can select which tests should be performed, including test order and frequency. Operators can also modify the test parameters, for example test duration and minimal airway pressure during the Valsalva test, and save these parameters in a custom user profile. Another relevant feature of the GAT application is that markers are automatically added to the measurement during all procedure steps, for example when a new maneuver is being started, executed or finished. These markers and corresponding time points are also included in the GAT report.
Video recording during Tilt Table test
A tablet records a video of the patients’ face during the Tilt Table test. After the test, this video can be synchronized with the measurements for a complete review via the NOVAscope PC application. Video recording is recommended by international autonomic testing guidelines, such as the ESC 2018 Guidelines for the diagnosis and management of syncope. They state: “Adding video recording to a tilt table test permits objective and repeated review of clinical signs in relation to Blood Pressure and Heart Rate, and helps to assess the relative contribution of bradycardia and hypotension to syncope”.
Guidance of the patient during Deep Breathing test
During the Deep Breathing test, the patient can follow the breathing rhythm that is visualized on the tablet. Moreover, it shows the remaining time to inhale and exhale according to the indicated rhythm. These features support a standardized procedure any time.
Guidance of the user and the patient during Valsalva test
During the Valsalva test, the patient blows into a mouthpiece that is connected to the Finapres® NOVA. The tablet provides instant feedback to the patient on this blown pressure and on the duration of the test. The operator can check the blown pressure to assess whether the subject has generated sufficient respiratory effort for an adequate Valsalva maneuver. When necessary, the pressure threshold and maneuver time can also be changed by the operator. When multiple Valsalva maneuvers are performed by the subject, the GAT application provides an overview of all available data. Thereby, the operator can select the best maneuver, which facilitates an accurate and quantified result.
GAT reporting
After finishing the tests, the GAT application creates a report with quantified results of all performed tests. Comments can be added by both the operator during the test and by the specialist during the measurement review. All comments appear on the first page of the PDF report.

Medical solutions for autonomic failure diagnosis sector - Medical / Health Care - Medical Monitoring
For over 30 years, Finapres® devices have been used by cardiologists, neurologists, physiologists and researchers to better understand autonomic failure, or dysautonomia. Many studies using Finapres devices® have been performed to show subjects’ neurological and cardiovascular reactions, including autonomic failure. Finapres® NOVA hardware and software support protocol-driven diagnosis of autonomic failure in patients and support documentation of treatment progress.
