Uncovering the Power of the NPi Pupillometer: A Comprehensive Guide to the Neurological Pupil Index Exam
The NPi pupillometer is a device that measures the size and reactivity of the pupils using the NPi or Neurological Pupil Index and provides valuable information about the function of the brainstem and autonomic nervous system. It assesses neurological conditions such as concussions, brain injuries, strokes, and mental health disorders. In this guide, we will explore the use and significance of the NPi exam, as well as its applications and limitations.
How does the NPi exam work? The NPi exam, also known as the Neurological Pupil Index exam, is a non-invasive evaluation of pupillary reaction that measures the responsiveness of a person's pupils to light. The exam is typically administered by a healthcare professional, such as a doctor or nurse. During the NPi exam, a small pupillometer shines light into the eyes. The pupillometer measures the size of the pupils in response to light and the time it takes for the pupils to constrict and dilate.
