Welcome to the fantastic world of FOUR Score calculation, where we blend numbers and neurology in a delightful cocktail of scientific precision! It’s like a soiree where everyone’s invited, but the doormen are neurologists. We assure you, it’s a lot more enjoyable than it sounds!
FOUR Score Calculation Formula
FOUR Score = Eye Response (ER) + Motor Response (MR) + Brainstem Reflexes (BR) + Respiration (R)

FAQs
- What is a FOUR Score? A FOUR Score is a tool used by clinicians to assess the level of consciousness in patients with impaired consciousness, particularly those in intensive care units.
- How is a FOUR Score calculated? A FOUR Score is calculated by adding the scores of four different components: Eye Response, Motor Response, Brainstem Reflexes, and Respiration.
- What does a high FOUR Score indicate? A high FOUR Score (13-16) indicates normal brain function.
- What does a medium FOUR Score indicate? A medium FOUR Score (9-12) indicates mild to moderate brain injury.
- What does a low FOUR Score indicate? A low FOUR Score (4-8) indicates severe brain injury.
- How accurate is the FOUR Score? The FOUR Score is highly accurate when calculated correctly. However, different practitioners may interpret responses differently, and medications may interfere with the patient’s responses.
- Are there alternative methods to the FOUR Score? Yes, one alternative method is the Glasgow Coma Scale (GCS), which is globally recognized but is less detailed compared to the FOUR Score.
- Can the FOUR Score change over time? Yes, a patient’s FOUR Score can change over time, reflecting changes in their neurological status.
- What factors can influence a FOUR Score? A FOUR Score can be influenced by several factors, including the patient’s underlying health conditions, the severity of their brain injury, and the effects of any medications they are taking.
- How often should a FOUR Score be calculated? The frequency of FOUR Score calculation depends on the patient’s condition and the judgment of the treating physician. In critical cases, it may be calculated multiple times a day.
