Rapid Acute Physiology Score (RAPS) - Medical Algorithm

Description

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

Parameter	Finding	Points
mean arterial pressure	<= 49	+4
	50 - 69	+2
	70 - 109	0
	110 - 129	+2
	130 - 159	+3
	>= 160	+4
heart rate	<= 39	+4
	40 - 54	+3
	55 - 69	+2
	70 - 109	0
	110 - 139	+2
	140 - 179	+3
	>= 180	+4
respiratory rate	<= 5	+4
	6 - 9	+2
	10 - 11	+1
	12 - 24	0
	25 - 34	+1
	35 - 49	+3
	>= 50	+4
Glasgow coma score	14 or 15	0
	11, 12 or 13	+1
	8, 9 or 10	+2
	5, 6 or 7	+3
	3 or 4	+4

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

RAPS =

= SUM(points for the 4 parameters)

Interpretation:

• minimum score: 0

• maximum score: 16
