Parasympathetic tone activity
Animal comfort
PTA
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
Veterinarians face a challenge when it comes to assessing animal’s surgical stress during surgery due to the absences of clear physiological signs. That’s why MDoloris developed a heart rate variability analysis device simple of use, not operator-dependent, based on the acquisition of electrocardiographic (ECG) signal.
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.

"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"
Miguel Angel Cabezas
"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"
