NPi-300 Pupillometer

The NPi-300 Pupillometer is a reliable handheld device for objective measurement of pupil reactivity in intensive care and also has an integrated barcode reader for 1D and 2D codes.

  • Technical data

    Infrared camera with light stimulus provided by LED lamps. Contactless inductive charging of the Li-ion battery.

  • MDD classification

    Class 1 LED product in accordance with IEC 60825.

  • Measurement

    During the automated measurement, a total of 90 images are captured within 3 seconds. Measurement accuracy: +/- 0.03 mm.

    The measurement result is displayed on the screen and saved on the SmartGuard. The data can be read out with a SmartGuard Reader and saved in a table as preparation for the PDMS.

  • Measured parameters:
    • NPi:
      Neurological Pupil index
    • MAX:
      Pupil diameter before light stimulus in mm
    • MIN:
      Smallest measured pupil diameter in mm
    • % CH:
      Percentage change in pupil size in %
    • CV:
      Average constriction velocity in mm/s
    • MCV:
      Maximum constriction velocity in mm/s
    • LAT:
      Time delay until reaction to light stimulus occurs in s
    • DV:
      Dilation velocity in mm/s
  • Evaluation of the NPi
    • 3,0 – 4,9:
      Normal pupillary response
    • < 3,0:
      Abnormal pupillary response*
    • 0:
      Non-reactive or atypical pupillary response

    *A difference in NPi between the right and left pupils of ≥ 0.7 may also be considered an abnormal pupil reading.

The NPi is a numerical indicator of pupil reactivity. Any change in the NPi can be objectively determined, displayed as a trend, and documented for further action.

Neuroptics NPi-200 Pupillometer

Angina is a coronary heart disease and can now be treated successfully with balloon dilatation, stent implantation, bypass surgery and medication.

Despite optimal treatment, some patients have persistent symptoms that can reduce their quality of life considerably. Even at rest or with little physical exertion, these patients suffer from chest pain, chest tightness or shortness of breath.

Implantation of a reducer to create a narrowing of the coronary sinus produces a back pressure that dilates the capillaries and thereby reduces resistance to blood flow.

After 4-6 weeks, the reducer is incorporated into the endothelial tissue, narrowing the coronary sinus to a diameter of 3 mm.

This normalises the pressure ratios in epicardial and endocardial blood flow, the chest pain subsides and other improvements are seen.

In Switzerland, the reducer is already being successfully implanted.

The conventional method for determining pupil size and reactivity is a manual penlight examination. This examination depends on the observer and is undoubtedly subjective.

The NPi®-300 Pupillometer from NeurOptics allows easy automated and reproducible measurements of pupil size, symmetry, the pupillary light reflex, and reactivity. Using an algorithm developed and validated by NeurOptics, all measurement parameters are combined in the device to give the NPi®.

Because the entire neurological network is involved, the NPi® provides an objective and accurate record of overall pupil reactivity.

The Pupillometer is therefore an important component of multimodal neuromonitoring, allowing easy access to many other pupillary response parameters.

Successive NPi measurements enable any change in the neurological condition of a patient to be recorded quickly and reliably. Measurements taken for each pair of eyes are stored on a device called SmartGuard. They can be displayed as a trend by the Pupillometer itself and transferred to a PC using a reader called SmartGuard Reader.

With additional software, pupil measurements can also be transferred to the digital patient record in the PDMS.

The NPi® (Neurological Pupil index) developed by NeurOptics has already been used in numerous studies and publications that depend on reliable measurements. It has also been included in guidelines (AHA and ERC).

Indications for pupillometry include objective, reproducible, and documentable pupillary response measurements in patients with stroke, subarachnoid hemorrhage, or traumatic brain injury. It can also be used as a prognostic tool in resuscitated cardiac arrest patients and patients on ECMO.
