How do you score a GCS assessment?
The final part of the GCS assessment involves assessing a patient’s motor response. You should score the patient based on the highest scoring response you were able to elicit in any single limb (e.g. if they were unable to move their right arm, but able to obey commands with their left arm, they’d receive a score of 6 points).
What is the GCS score for verbal response?
Verbal response (V) The GCS score is the sum of the score in each of the three categories, with a maximum score of 15 (normal) and a minimum score of 3 (deep unconsciousness), as follows: GCS score = E + M + V
What are the components of the GCS?
The score is made up of three components: eyes, verbal and motor. The scale is from 3 (completely unresponsive) to 15 (fully alert). It is not possible to achieve a score of zero! Orientated means the patient is aware where they are (place), who they are (person) and the current date. The motor score is the most complex part of the GCS assessment.
What is the GCS and PGCs scale?
Similar to the adult version, the sum of the eye response, motor response, and verbal response equals the PGCS. The highest score is a 15 (fully awake and aware) and the lowest is 3 (deep coma or brain death). The GCS and PGCS can be confusing at times but understanding the basics is the first step in mastering the scale.
How do you examine GCS?
To calculate the patient's GCS , you need to add together the scores from eye opening, verbal response and motor response. Added together, these give you an overall score out of the maximum of 15.
What are the 3 areas of GCS assessment?
[1] The Glasgow Coma Scale (GCS) is used to objectively describe the extent of impaired consciousness in all types of acute medical and trauma patients. The scale assesses patients according to three aspects of responsiveness: eye-opening, motor, and verbal responses.
What is normal GCS score?
The responses are scored between 1 and 5 with a combined total score of 3 to 15, with 15 being normal. An initial score of less than 5 is associated with an 80% chance of being in a lasting vegetative state or death. An initial score of greater than 11 is associated with 90% chance of recovery.
How do you assess motor response in GCS?
Motor responseScore 6: obeys commands. The patient can perform two different movements;Score 5: localises to central pain. ... Score 4: withdraws from pain. ... Score 3: flexion to pain. ... Score 2: extension to pain. ... Score 1: no response to painful stimuli.
What are the three categories measured in the Glasgow Coma Scale and how are they scored?
The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These three behaviors make up the three elements of the scale: eye, verbal, and motor. A person's GCS score can range from 3 (completely unresponsive) to 15 (responsive).
What does a GCS of 3 mean?
Patients with head injury with low Glasgow Coma Scale (GCS) scores on hospital admission have a poor prognosis. A GCS score of 3 is the lowest possible score and is associated with an extremely high mortality rate, with some researchers suggesting that there is no chance of survival.
What is GCS 3 in medical terms?
The GCS is the summation of scores for eye, verbal, and motor responses. The minimum score is a 3 which indicates deep coma or a brain-dead state. The maximum is 15 which indicates a fully awake patient (the original maximum was 14, but the score has since been modified).
What are the 5 levels of consciousness medical?
Often, an altered level of consciousness can deteriorate rapidly from one stage to the next, so it requires timely diagnosis and prompt treatment.Confusion. ... Delirium. ... Lethargy and Somnolence. ... Obtundation. ... Stupor. ... Coma.
How do you assess the level of consciousness using the Glasgow Coma Scale?
There are three aspects to the GCS that are assessed to determine a patient’s level of consciousness. They are motor responsiveness, verbal perform...
What is a good score on the Glasgow Coma Scale?
The highest possible score is 15 (fully conscious) and the lowest possible score is 3 (coma or dead).
What are the 5 levels of consciousness?
Conscious, Preconscious, Unconscious, Non-conscious, and Subconscious.
What does a Glasgow Coma Scale of 8 or less indicate?
Patients with a Glasgow Coma Scale score of 8 or less are considered to have suffered a severe head injury.
What does a 6 on the Glasgow Coma Scale mean?
Patients with a Glasgow Coma Scale score of 7 or less are considered comatose.
What does a GCS of 15 mean?
A GCS of 15 means a patient is fully conscious.
Can you recover from a GCS of 7?
Yes, a patient can recover with the proper medical care.
How do you calculate GCS intubated?
The maximum GCS score is 10T and the minimum score is 2T for intubated patients.
What are the components of the Glasgow Coma Scale?
The three components are motor responsiveness, verbal performance, and eye-opening.
When To Use The GCS
The patients who need a GCS assessment have generally suffered a traumatic brain injury and are either in the ER or ICU. An initial GCS should be done at time of admission and then every four hours unless otherwise indicated by the medical team.
Limitations of the GCS
While the Glasgow Coma Scale is a great diagnostic tool there are multiple limitations that can alter the score and not provide an accurate picture of the patient’s brain injury. These include:
Pediatric Glasgow Coma Scale
Another significant limitation of the Glasgow Coma Scale, as it was originally developed, is that it does not accurately measure traumatic brain injury in children under 5 years of age. The aptly-named ‘Pediatric Glasgow Coma Scale (PGCS)’ includes modifications for this patient population.

Observe
Observe for spontaneous behaviours in any of the three components of the GCS.
Stimulate
Verbal and physical stimuli will be needed in patients without spontaneous behaviours.
Rate
Judge observed response against presence or absence of defined criteria.
1. What factors can interfere with assessment of the Glasgow Coma Scale and what can be done about them?

2. How is the Glasgow Coma Scale modified for Children?
The scale can be applied without modification to children over 5 years old. In younger children and infants, an assessment of a verbal response as “orientated” and motor response as “obeys commands” is usually not possible.
3. What is the reliability of the Glasgow Coma Scale? How is it optimised?
Consistency in its findings is a key feature of a clinical assessment and during the development of the Glasgow Coma scale it was shown to be better than existing methods.
4. Is the Glasgow Coma Scale only for use in Head Injuries?
The Glasgow Coma Scale can be applied to describe impairment of consciousness from any cause. It has found most use in head injuries, but reports of its application in impaired consciousness from other aetiologies are indicated below.
5. When and how often should Observations be recorded?
The timing and frequency of assessment that are appropriate varies according to the stage after onset of the impairment of consciousness and the pattern in any previous observations of a patient.
6. How much change is important?
Rigid criteria for what changes should prompt actions are not appropriate; circumstances vary widely and the role of the scale is to support not replace clinical decision-making. Nevertheless, some factors can provide guidance.
7. What are the relationships and roles of the Coma Scale and the Coma Score?
The core concept in the Scale is that the patient’s eye, verbal and motor responses are described in simple, objective terms in order to convey a clear unambiguous picture of their condition. 1 The allocation of numbers to the steps in the three responses (e.g.

Doctors use the Glasgow Coma Scale to assess a patient's level of consciousness.
