- NEWS2: (i) The oxygen saturation should be scored according to either the SpO2 Scale 1 or 2 presented in the table above. The SpO2 Scale 2 is for patients with a target oxygen saturation requirement of 88–92% (e.g., in patients with hypercapnic respiratory failure related to advanced lung diseases, such as chronic obstructive pulmonary disease [COPD]). This should only be used in patients confirmed to have hypercapnic respiratory failure by blood gas analysis on either a prior or their current hospital admission. The decision to use the SpO2 Scale 2 should be made by the treating physician and should be recorded in the eCRF. In all other circumstances, the SpO2 Scale 1 should be used. (ii) For physiological parameter “Air or Oxygen?”: Any patients requiring the use of oxygen or other forms of ventilation to maintain oxygen saturations and support respiration should be assigned a score of 2. (iii) The consciousness level should be recorded according to the best clinical condition of the patient during the assessment. Patients who are assessed as “Alert” (A) should be assigned a score of 0. Patients assessed as “New Confusion” (C), “Responsive to Voice” (V), “Responsive to Pain” (P), or “Unconscious” should be assigned a score of 3
