NOL Pain Response Monitor | Medtronic (UK)

Managing nociception during surgery is a major challenge, impacting patient outcomes, length of stay and cost of treatment.

Excessive use of opioids may result in intraoperative hypotension, respiratory depression, PONV etc.,^1,2,3and underuse of analgesics may promote acute or chronic post-operative pain, delayed recovery and the costs associated with these complications.^4,5,6

The PMD-200^TM nociception monitor, developed by Medasense Ltd., helps you monitor your anaesthetized patients' physiological pain response (nociception) to noxious stimuli and tailor analgesic medications to each patient’s specific sensitivity and needs. The integrated nociception level index (NOL^®) provides superior indication of the presence and severity of pain response vs. individual parameters (such as changes in heart rate and blood pressure) to reduce complications and improve patient outcomes.^7,8

1. ACQUIRE → 2. ANALYZE → 3. QUANTIFY → 4. OPTIMAL PAIN CARE

ACQUIRE

The non-invasive platform continuously acquires physicological signals through 4 sensors. Dozens of physiological parameters and derivatives are extracted

ANALYZE

Advanced articificial intelligence algorithms identify the pain-related pattern

QUANTIFY

The information is quantified and visualized with the NOL^® index on a scale of 0 (no nociceptive response) to 100 (extreme nociceptive response)

OPTIMAL PAIN CARE

NOL^® guides clinicians to ensure optimal pain control while avoiding overmedication

Potential to Reduce Post-Operative Complications

By optimizing analgesic administration in critical care, NOL^®-guided analgesia might enhance the patient experience as it reduces the risk of excessive use or underuse of opioids and associated complications.⁹
