NOL Technology

Control pain. Avoid overdose. Eliminate doubt.

The NOL – Nociception Level Index®

NOL (Nociception Level) is the technology and index developed by Medasense to objectively quantify a patient’s physiological pain response (nociception), enabling clinical teams to provide personalized pain treatment.

Medasense’s flagship product, PMD-200™ applies this technology in critical care settings to visualize pain response and personalize treatment. Recent evidence shows that NOL-guided surgery results in 33% less pain.1 Other studies have shown that NOL-guided analgesia reduces the risk of excessive use or underuse of opioids and associated complications.2

Medasense is developing its pipeline products for clinics and home care, to lead pain prediction, stratification and prevention strategies.

Control Pain

Objectively measure pain and tailor analgesia dosing to each patient’s needs.

Avoid Overdose

Patients vary in their pain threshold and response to opioids.3 Avoiding excessive use of opioids can improve patient safety and outcomes.2

Eliminate Doubt

NOL monitoring enables confident assessment of the adequacy of pain treatment.

How It Works

The Physiological Principles Behind NOL

NOL is based on a proprietary, patented artificial intelligence technology that quantifies the individual physiological response to pain in real-time, continuously and noninvasively.

Activation of the sympathetic nervous system, as a result of multiple stimuli and inputs, leads to a constellation of nociception-related physiological responses, with complex inter-associations and different response profiles. Recognizing the complex nature of this process, the Nociception Level (NOL) index was developed as a multiparameter composite of autonomic signals.
