The Rapid Acute Physiology Score (RAPS) is a severity scale which can be used to assess patients being transported between intensive care units. This is a simplified version of the Acute Physiology and Chronic Health Evaluation (APACHE II) score.
Parameters:
(1) mean arterial pressure
(2) heart rate
(3) respiratory rate
(4) Glasgow coma score

where:
• mean arterial pressure = ((2* (diastolic pressure)) + (systolic pressure)) / 3
• The respiratory rate is either (1) the spontaneous respiratory rate or (2) the ventilated rate if not spontaneous

= SUM(points for the 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 16
