The GCS can help guide trained clinicians such as physicians, nurses, and emergency medical technicians in determining appropriate interventions and identifying trends in a patient\u2019s condition. <\/p>\n<p>The GCS is commonly used for patients with traumatic brain injuries, but can be used to assess consciousness in many situations. A modified version of the GCS can be used to assess consciousness in children under 5 years of age.<\/p>\n<h2><span id=\"GSC_Components\" class=\"m-toc-anchor\"><\/span>GSC Components<\/h2>\n<p>\nThe Glasgow Coma Scale is comprised of three components\u2014eye opening, verbal response, and best motor response. <\/p>\n<p>These are assessed individually before the scores in each category are added together. <\/p>\n<p>The highest scores in each category are given to the most normal assessment findings, and the lowest scores indicate no response.<\/p>\n<p>Before performing the assessment, it is important to check for any factors that might interfere with accuracy, such as language barriers or other injuries.<\/p>\n<h3><span id=\"1_Eye_Opening\" class=\"m-toc-anchor\"><\/span>1. Eye Opening<\/h3>\n<p>\nThe first category of assessment is eye opening. These are the applicable ratings:<\/p>\n<ul style=\"list-style-type: none;\">\n<li style=\"margin-bottom: 10px;\"><strong>4<\/strong> \u2013 Spontaneous opening of the eyes.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>3<\/strong> \u2013 A patient whose eyes open in response to a spoken or shouted verbal request.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>2<\/strong> \u2013 If the patient\u2019s eyes do not open in response to sound, physical stimulus is applied in the form of increasing pressure to a fingertip for up to ten seconds.<\/li>\n<li><strong>1\/NT<\/strong> \u2013 No response during this assessment is rated a 1, but the presence of an interfering factor such as swelling of the eyes that prevents opening should be rated as \u201cnon-testable,\u201d or \u201cNT.\u201d<\/li>\n<\/ul>\n<h3><span id=\"Verbal_Response\" class=\"m-toc-anchor\"><\/span>Verbal Response<\/h3>\n<p>\nThe second category of assessment is verbal response. These are the applicable ratings:<\/p>\n<ul style=\"list-style-type: none;\">\n<li style=\"margin-bottom: 10px;\"><strong>5<\/strong> \u2013 A fully oriented and communicative patient.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>4<\/strong> \u2013 A patient who is able to express verbal thoughts in phrases or sentences but is not oriented.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>3<\/strong> \u2013 A patient who can speak single-word responses.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>2<\/strong> \u2013 A patient who moans, groans, or uses unintelligible words.<\/li>\n<li><strong>1<\/strong> \u2013 No audible verbal response without an interfering factor such as a tracheostomy.<\/li>\n<\/ul>\n<h3><span id=\"Motor_Response\" class=\"m-toc-anchor\"><\/span>Motor Response<\/h3>\n<p>\nThe third category of the Glasgow Coma Scale is best motor response. These are the applicable ratings:<\/p>\n<ul style=\"list-style-type: none;\">\n<li style=\"margin-bottom: 10px;\"><strong>6<\/strong> \u2013 A patient who can obey a simple two-step command such as opening his or her mouth and sticking out his or her tongue.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>5<\/strong> \u2013 If the patient responds to the central stimulus by bringing one arm across to try to remove the stimulus, it is considered \u201clocalizing.\u201d<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>4<\/strong> \u2013 The response of normal flexion of an arm that is not directed toward removing the stimulus.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>3<\/strong> \u2013 Abnormal flexion may appear as a slowed response of bringing the arm toward the body.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong>2<\/strong> \u2013 The elbows extend instead of flex in response to the stimulus.<\/li>\n<li><strong>1\/NT<\/strong> \u2013 No motor response is rated a 1, while patients with interfering factors, such as pharmacologically induced paralysis, should be rated \u201cNT.\u201d<\/li>\n<\/ul>\n<p>The score for each of the three categories is added together, with a total possible score of up to 15; and the lowest possible score of 3. <\/p>\n<h2><span id=\"Glasgow_Coma_Scale_Score_Meaning\" class=\"m-toc-anchor\"><\/span>Glasgow Coma Scale Score Meaning<\/h2>\n<p>\nOnce the score of a patient has been identified, it is important to understand the meaning. <\/p>\n<p>When scoring a patient with a brain injury, they are generally classified as severe, moderate, or mild.<\/p>\n<ul>\n<li>Severe is 3-8 on the Glasgow Coma Scale<\/li>\n<li>Moderate is 9-12 <\/li>\n<li>and Mild is 13-15. <\/li>\n<\/ul>\n<p>The purpose of the scale is to complement, but not replace assessments of other neurological functions.<\/p>\n<p>Thanks for watching, and happy studying!<\/p>\n<ul class=\"citelist\">\n<li><a href=\"https:\/\/www.glasgowcomascale.org\/downloads\/GCS-Assessment-Aid-English.pdf?v=3)\"target=\"_blank\">\u201cAbnormal Flexion.\u201d n.d.<\/a><\/li>\n<p>\n<\/ul \n\n<\/div>\n<\/div>\n\n<div class=\"home-buttons\">\n<p><a href=\"https:\/\/www.mometrix.com\/academy\/patient-care\/\">Return to Patient Care Videos<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Return to Patient Care Videos<\/p>\n","protected":false},"author":1,"featured_media":99640,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":{"0":"post-69464","1":"page","2":"type-page","3":"status-publish","4":"has-post-thumbnail","6":"page_category-neurologic-system-videos","7":"page_category-patient-care-videos","8":"page_category-video-pages-for-study-course-sidebar-ad","9":"page_type-video","10":"subject_matter-nursing"},"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 4.9.8 - aioseo.com -->\n\t<meta name=\"description\" content=\"The Glasgow Coma Scale was developed to test a patient&#039;s level of consciousness and can be modified for children.
