as part of the admission examination, a Glasgow score of three to five points often suggests that the patient has likely suffered fatal brain damage, while eight or more points indicates that the patient's chances for recovery are good.
The social responsiveness scale (SRS)
The Glasgow Coma Scale (GCS) is a tool medical professionals use to objectively evaluate the degree to which a person is conscious or comatose. Also referred to as the "Glasgow Coma Score," it operates on a scale of "3" to "15," in which progressively higher scores indicate higher levels of consciousness. For example, while a patient who is profoundly unconscious would receive a 3 according to the Glasgow Coma Scale, conscious, healthy adults would be rated at 15. Immediately after a head trauma, emergency doctors and nurses will use the Glasgow Coma Scale to assess a patient's condition. Others who use the GCS include intensive care staff, EMTs and chronic care professionals. If a person has a brain injury resulting in a GCS of 3, it is most likely that the person has suffered some amount of brain damage.

AVPU scale stands for alert, verbal, pain, unresponsive
General rule is less than 8...that being said there are very few always and nevers in medicine. A 2009 study of 73 patients with Glasgow scale less than 12 (many less than 8) did not intubate and they did not aspirate. A better answer would be to thoroughly assess the patient including history if available when deciding whether to tube or not.
In the middle are those patients who may be able to respond, but who require an intense or painful stimulus, and whose response may demonstrate some degree of brain malfunctioning
severe head injury
Glasgow Coma Scale-GCS
The Glasgow Coma Scale is a method of quantifying neurological dis-impairment by assigning values to eye actions, verbal responses, and motor skills. Possible values range from 15 (alert and unimpaired) to 3 (deep coma or death). A Glasgow of 4 is indicative of significant coma or neurological impairment.
The NIH Stroke scale is a tool used by medical professionals to evaluate a patient's neurological deficits following a stroke. This tool is used in part to predict what the patient's short and long term outcomes will be.
The facts of the scale would not be protected, but expressions of it would be--for example, taking an image of the scale from a journal and including it in a new document would require permission.

Japan uses the Richter scale to measure earthquakes. This scale quantifies the energy released by an earthquake using a logarithmic scale from 1 to 10. In addition to the Richter scale, Japan also uses the Japan Meteorological Agency (JMA) seismic intensity scale to evaluate the intensity of shaking felt at specific locations.
