There are many types of early warning charts in use:
Modified early warning score (Table 1)
Example EWSS 2 (Table 2)
Example EWSS 3 (Table 3)
Sign | Measure |
Respiratory rate | Breaths per minute (bpm) |
Heart rate | Beats per minute (bpm) |
Blood pressure | mmHg |
Conscious level | AVPU scale |
Temperature | Degrees Celcius |
Urine output | ml per hour |
