What are the 5 parameters and nursing observation that comprise a MEWS score?
It is based on the EWS model and accounts for 4 patient parameters (systolic BP, heart rate, respiratory rate and temperature) and a level of consciousness assessment (AVPU).
What is a MEWS score of 3?
For a critical total MEWS score of ≥5 or a single physiological parameter score of 3, they observed a significant increase in relative risk and therefore a higher level of care may be warranted. The parameters and criteria used in this study are the ones used for this calculator.

- Systolic BP. ≤70 mmHg. +3. 71-80 mmHg. +2.
- Heart rate. <40 bpm. +2. 41-50 bpm. +1.
- Respiratory rate. <9 bpm. +2. 9-14 bpm.
- Temperature. <35°C / 95°F. +2. 35–38.4°C / 95–101.1°F.
