PTA
Following the results of the ANI technology (Analgesia Nociception Index)
on the monitoring of non-communicating patients, an adaptation of the algorithm was performed
to develop the PTA index (Parasympathetic Tone Activity). The PTA technology enables the evaluation
of the parasympathetic part of the autonomic nervous system of animals
The first parasympathetic tone monitoring device in the world for pets
The PTA index provides an objective value to veterinarians to evaluate analgesia. The monitor offers a value between 0 and 100 corresponding to the percentage of activity of the parasympathetic part of the Autonomic Nervous System of the animal. The higher the value of the PTA index is the higher the animal’s comfort.

Testimonials
Our technologies are used by top physicians around the world
In my opinion, the inclusion of PTA in the monitoring protocol allows us to complete the information and refine the treatment in something as complicated as nociception, thinking not only intraoperatively but also in postoperative pain
Dr. Miguel Angel Cabezas
Head of the Anesthesia at Hospital Veterinario Puchol, Madrid
Currently, the clinical assessment method for nociception (intraoperative ‘pain’) is based on simple but basic responses, such as sudden increases in heart and respiratory rates or blood pressure. These responses imply that we are late in providing a good pain reliever and stability plan for our patients. The PTA monitor is a novel approach and a significant advance to detect the presence of nociception, and to anticipate situations where our patients do not have sufficient analgesic coverage.
Dr. Ignacio Álvarez Gómez de Segura
Chef of the Anesthesiology department at Universidad Complutense de Madrid
The evaluation of the autonomic nervous system during general anesthesia allows for more accurate control of what happens after nociceptive stimuli. The PTA monitor allows me to detect most of the sympathetic responses that occur during surgery, even the ones that are very slight and do not cause major changes in blood pressure and heart rate.
