High Frequency Variability Index
HFVi
The High Frequency Variability Index (HFVi) is an innovative technology that provides a measurement of the parasympathetic tone in order to continuously evaluate the patient’s comfort level. Thanks to the international, independent publications we can provide anesthesiologists a device and a measurement that will individualize and refine their daily practice of anaesthesia. Using HFVi, doctors can assess the sympathetic/parasympathetic balance allowing them to TAKE CONTROL OF THE SURGICAL STRESS.
From ECG to HFVI:
heart rate variability computation
Heart Rate Variability is a well-known phenomenon that controls the regulation of the cardiovascular system via the Autonomic nervous system. By analyzing the heart rate variability oscillations, it reflects the activity of the sympathetic and parasympathetic nervous systems.
Developed in order to provide clinicians a monitoring system of analgesia matching the requirements of routine clinical practice, in other words, easy to use, easy to interpret, reliable, and continuous. During general anesthesia, the HFVi range relates to adequate analgesia, which means that antinociception is adequate and that the parasympathetic activity is mildly predominant over sympathetic activity.

Testimonials
Our technologies are used by top physicians around the world in both OR and ICU settings
"The MDoloris technology has been a very
valuable tool in intraoperatively. The HFVI
provides us with more information on
the patients’ status, allowing us a better
decision making."
Dr. Tiffany Moon
"I find that using HVFI during anesthesia brings
additional knowledge and appreciation of
what is happening to the patient during
the surgery. It gives me more confidence in
treating hemodynamic responses and is easy
and reassuring to interpret."
Dr. Irene Osborne
