An altered level of consciousness is any measure of arousal other than normal. Level of consciousness (LOC) is a measurement of a person's arousability and responsiveness to stimuli from the environment. [1] A mildly depressed level of consciousness or alertness may be classed as lethargy; someone in this state can be aroused with little ...
The Glasgow Coma Scale [1] (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury. The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These three behaviours make up the three elements of the scale: eye, verbal, and motor.
In the hospital or long term healthcare facilities, caregivers may consider an AVPU score of less than A to be the patient's normal baseline. [3] In some emergency medical services protocols, "Alert" can be subdivided into a scale of 1 to 4, in which 1, 2, 3 and 4 correspond to certain attributes, such as time, person, place, and event. For ...
GCS was initially used to assess level of consciousness after head injury and the scale is now used by first aid, EMS and doctors as being applicable to all acute medical and trauma patients. In hospital it is also used in chronic patient monitoring, in for instance, intensive care.
The FOUR Score is a clinical grading scale designed for use by medical professionals in the assessment of patients with impaired level of consciousness.It was developed by Dr. Eelco F.M. Wijdicks and colleagues in Neurocritical care at the Mayo Clinic in Rochester, Minnesota.
Obtundation is mild to moderate alertness reduction (altered level of consciousness) with decreased interest in the environment and slower than normal reactivity to stimulation. [citation needed] It is distinguished from the much stronger states of unresponsiveness of stupor and coma.
But cerebral metabolism has been shown to correlate poorly with the level of consciousness in patients with mild to severe injury within the first month after traumatic brain injury (TBI). [16] A person in a state of coma is described as comatose. In general patients surviving a coma recover gradually within 2–4 weeks.
The medical approach focuses mostly on the amount of consciousness a person has: in medicine, consciousness is assessed as a "level" ranging from coma and brain death at the low end, to full alertness and purposeful responsiveness at the high end.
