ANI MONITOR V2

Our stand-alone solution. Robust against artifacts. Get more and better ANI measurement.

The ANI (Analgesia Nociceptor Index) is an innovate parameter that allows assessing the level of comfort in hospitalized patients as demonstrated in a 2023 published meta-analysis. 

ANI Index from 2 years old until end of life

ANI Measurement

The parasympathetic tone measurement is represented by 2 indicators : ANIm & ANIi respectively the activity of the ANS in the last 4 and 2 minutes.
The ANI index permit to the anesthesiologist to adapt and anticipate opioid need so the patient can benefit of an adequate anesthesia, with several peri and post operative benefits.

Nb : The energy must be between 0,05 and 2,5 for an interpretable ANI.

ANIm

The ANIm is the general view of the ANI trend. It permit to observe the evolution of the ANI during the surgery, being less volatile than the ANIi.

ANIi

The ANIi permit by itself to consider the exact instantaneous reaction  of the patient during the surgery, meaning the impact of an incision or an opioid injection for example, will be visible in the ANIi indicator in the minute following.

Energy

Scientifically, the Energy is represented by the standard deviation of the cardiac variability over the last 64 seconds. In other words it represents the power of the parasympathetic tone.

ANI Measurement Benefits

A recent 2023 Korean Meta-analysis on 30 ANI studies hascome to 4 confirmations:

Accuracy of pain / Nociception in ANI monitoring during general anesthesia
ANI monitoring can reduce intraoperative opioid consumption
Applicability of ANI monitoring for predicting postoperative pain
Correlation between hemodynamic changes and ANI monitoring
