NPi-300 Pupillometer
Completely accurate, reliable and objective pupillary size measurement and reactivity data independent of examiner
- Pupil reactivity expressed numerically so that now changes in both pupil size and reactivity can be trended over time, just like other vital signs
- Infrared camera, high-precision optics, processor and LED light source
- Modern Graphical User Interface (GUI) features simple and intuitive icon-based navigation
- Upgraded keypad – easy-to-press buttons designed for fast and simple navigation with or without gloves
- Durable, ergonomic design
- Industry-best full two-year replacement warranty
Determining normal or abnormal pupil reactivity is often difficult and sometimes impossible with manual penlight pupil assessment. NPi® solves this problem.
Pupillary Effects of High-Dose Opioid Quantified with NPi Pupillometry

An examiner using manual penlight pupil assessment in these patients might conclude abnormally reacting pupils when in reality, the pupils are reacting normally as shown with NPi

NPi confirms abnormally
reacting pupils and possible
need for acceleration of care
The Neurological Pupil index TM (NPi®) Pupil Reactivity Assessment Scale

* A difference in NPi between right and left pupils of ≥ 0.7 can also be considered an abnormal pupil reading
* Per the Neurological Pupil index (NPi) algorithm
