A new high-tech tool is helping researchers to treat patients with neurological disorders. Many researchers are using NPi for pupillary size measurement and evaluating the functioning of the autonomic nervous system, gauging the metabolism of drugs, observing drug injury and fatigue, and many other applications. The NPi-200 Pupillometer is authentic, reliable, and eliminates subjectivity.

NPI: a revolutionary invention
NPI uses the contour of the pupil for pupil measurement. This latest digital pupilometer allows medical specialists to measure the distance between the center of each pupil. The spectrum changes from 47 to 84 mm in 0.5mm steps. The corneal reflection pupil diameter measurement measures the distance between the center of each pupil.
By allowing rigorous performance and classification of the pupil response, the index has contributed to offering increased conviction in neurological assessment.
What does NPI mean?
The Neurological Pupil index, or NPi, is an algorithm formulated by NeurOptics, Inc. The device helps remove subjectivity from the pupillary evaluation.
Pupillometer calculates the NPi and indicates a comparison of all measured variables in the PLR to known normal observations. On the numeric scale of NPi, the index from 3.0 to 4.9 is considered normal, while an NPi less than 3.0 is deemed as abnormal.
NPi on assessing Pupil Reactivity
Pupil reactivity or pupillary response is a physiological reaction that differs the size of the pupil via the optic cranial nerves and oculomotor. The constriction response or the narrowing of the pupil may be caused by drugs such as medications to treat hypertension or opioids.
The handheld noninvasive optical scanner provides valid and objective measurements of pupillary size, reactivity, and symmetry. With a gentle flash of light as the infrared camera, the device stimulates pupil constriction measuring all the parameters comprising the entire pupillary light reflex.
The resourceful technology is being used in the evaluation of pupillary light reflex, which has contributed to neurosurgery, critical care medicine, neurology, emergency medicine, and applied research.
This objective, precise, and reliable system has improved pupil evaluation. NPI pupillometer helps to detect cerebral insult, inform prognosis, and guide treatment.
Role of NPi in Neuro Critical Care
The invention of the NPi-200 Pupillometer has proven to be an objective means of evaluating and trending pupillary reactivity across a broad spectrum of neurological diseases, including traumatic brain injury, ischemic and hemorrhagic stroke, and cerebral edema, and Status Epilepticus.
As a prognostic tool, the Automated Pupillometer can demonstrate emerging value, with predictive properties that allow practitioners to foresee neurological injury as well as retrieval.
On Treating Traumatic Brain Injury
Clinicians need to check the pupils of critically injured and ill patients routinely to monitor neurological status. The manual pupil measurements are inaccurate, subjective, and not consistent or repeatable. Therein lies the importance of using NPi, a cutting-edge advanced neurological tool.
In ICUs, pupillometers are used to assess neurological details of gravely ill patients. Besides measuring pupillary size and reaction, NPi is literally a revolution beneficial for optical pupillometry in traumatic brain injury.
The NPi works the best in such conditions by providing impeccable service. The tool makes a big difference in several cases, and one of them is assessing the pupillary response in traumatic brain injury.
Recognized as the cutting-edge tech revolutionizing neurological tools in the ICU, automated pupillometry like NPi is being adopted in hospitals worldwide. Pupillometer has been accepted as a standard of care for pupillary assessment in patients in critical care nursing.
Other Critical Illnesses
Automated pupillometry is also proving useful to patients with potential for neurologic complications from conditions such as cardiac arrest, acute respiratory distress syndrome (ARDS), liver failure, and sepsis; also in procedures like mechanical ventilation and extracorporeal membrane oxygenation (ECMO).
