*Glasgow Coma Scale* **Intended Use** NEWS2 applies to adults aged 16 and over and is not validated for children or during pregnancy. SpO2 Scale 2 must only be used for patients with confirmed hypercapnic respiratory failure and a prescribed oxygen saturation target of 88–92%. **Intended Use** The Glasgow Coma Scale rates a patient's level of consciousness from the eye, verbal and motor responses. Report the three components alongside the total (e.g. E3 V4 M5 = 12) — the same total can arise from different combinations. If a component cannot be tested (for example the verbal response in an intubated patient), leave it unselected: it is reported as NT (not testable) rather than scoring 1, adds nothing to the total, and the severity is not graded. **Source** Teasdale G, Jennett B.
